Survey assessing foot trimmer involvement in managing lameness in UK beef cattle.

BACKGROUND: Cattle lameness is a significant welfare and economic problem facing the livestock industry. Published research has investigated foot trimming practices in dairy herds, but little is known about the practices in beef herds. Therefore, the objective of this study was to obtain information about the current practices of professional cattle foot trimmers concerning beef cattle within the UK. METHODS: An online survey comprising 16 questions was created using the Joint Information Systems Committee platform. The survey was open for 3 months. RESULTS: There was a significant difference (p < 0.05) between the proportions of dairy cattle and beef cattle receiving preventative foot trims. Digital dermatitis was the most commonly recorded cause of lameness when a lame beef animal was trimmed by the respondents, followed by white line disease. A thematic analysis of foot trimmers' opinions of barriers to engagement on beef farms is presented, in addition to their opinions on veterinary involvement with beef lameness. LIMITATIONS: Distribution bias may have affected the results, as the survey was distributed online with support from the Cattle Hoof Care Standards Board and the National Association of Cattle Hoof Trimmers. The percentage of foot trimmers not affiliated with either professional body is not known. CONCLUSION: Further research on the impact of lameness on suckler and finishing cattle, including investigations into preventative actions to reduce lameness in beef systems, is warranted.

Evaluation of potassium monopersulfate footbath solution for controlling digital dermatitis in lactating dairy cattle. A randomized clinical trial.

Our objective was to assess potassium monopersulfate as a disinfectant used in footbath to control digital dermatitis (DD) in dairy cows. We hypothesized that a potassium monopersulfate solution would control DD. A 180-day randomized negative controlled trial was conducted in a 265-Holstein free-stall facility. Throughout the trial, foot bathing was performed bi-weekly using a split (left vs. right feet) footbath: one tub filled with 1% potassium monopersulfate (treatment), the other with tap water (control). Digital dermatitis lesions were scored during trimming chute examinations of the unwashed hind heels every 90 days using the modified M-scoring system. Digital dermatitis lesions were re-categorized into four variables: 1) inactive; 2) active; 3) any; 4) inactive or absence of DD lesions. Three longitudinal outcomes were characterized: risks of 1) developing a DD lesion; 2) reactivating an inactive DD lesion; 3) development of an inactive or the absence of the DD lesion. A generalized linear model was used to compare the variables and longitudinal outcomes between treated and control groups. Prevalence of active DD lesions increased from 12.5% to 39.9% between days 0 and 90. This significant increase in prevalence justified the discontinuation of the study on day 90 for ethical reasons. There was no statistical difference between treated and control groups for the first outcome (RR: 1.0; 95% CI: 0.62, 1.7), the second outcome (RR: 1.0; 95% CI: 0.62,-1.7); or the third outcome (RR: 0.88; 95% CI: 0.37, 2.1). A 1% potassium monopersulfate footbath solution appears ineffective to control DD in this study.

Continuous digital hypothermia for prevention and treatment of equine acute laminitis: A practical review.

Laminitis is a severely debilitating and life-threatening condition that occurs as a consequence of different primary triggering factors. Continuous digital hypothermia (CDH) is recommended in horses at risk of, or diagnosed with, acute laminitis due to its several physiological and biochemical alterations that may be positive for the prevention and early treatment of the condition, representing a low risk of adverse effects. Modulation of the inflammatory response, profound vasoconstriction, and prevention of tissue damage are the most notable protective effects of cryotherapy on the lamellae. This practical review aims to summarize the published literature evaluating CDH efficacy in the prevention and early treatment of acute laminitis in horses, highlighting the most important clinical findings and discussing the best methods to provide cryotherapy. Nineteen publications evaluated different CDH methods, including the use of commercially available ice boots or fluid bags filled with iced water or crushed ice, as well as alternatives to immersion in ice, e.g., frozen gel packs and a perfused cuff prototype. Although some techniques were effective for cooling and maintaining the hooves below the optimal temperature of 10 °C, relevant limitations such as labor intensiveness, reliance on an ice source and price make its use impractical in some clinical situations. Twelve experimental studies assessed the efficacy of CDH on the prevention or early treatment of laminitis, finding multiple positive effects in terms of clinical improvement, immunological and inflammatory modulation, and histological protection. After the analysis of the literature, the clinical importance of CDH in different stages of laminitis remains clear. However, it also highlights the need for a safer, more user-friendly, and more effective method of cryotherapy that can be used both in a hospital and an ambulatory setting.

Investigating the effect of prophylactic claw trimming on the interval between calving and first observed elevated locomotion score in pasture-based dairy cows.

AIMS: To evaluate, in a pasture-based dairy herd, the response to a three-time point hoof trimming regime on lameness incidence and time from calving to observation of an elevated locomotion score (LS). METHODS: This study was conducted on a 940-cow spring-calving herd in New Zealand's North Island between May 2018 and May 2019. Cows (n = 250) were randomly allocated to the hoof trimming group, with the remainder assigned to the non-trim cohort. One trained professional hoof trimmer used the five-step Dutch method to trim the hind feet of the trimming group. Throughout the subsequent production season, the whole herd was locomotion-scored fortnightly using the 4-point (0-3) Dairy NZ lameness score. Kaplan-Meier survival curves were used to assess the univariable effect of trimming on the interval between calving and first LS of ≥ 2 and first LS ≥ 1. A multivariable Cox proportional hazards regression was used to further evaluate the effect of trimming on time to elevated LS. RESULTS: Mean lameness (LS ≥ 2) prevalence was 2.6%, with 30% of cows having ≥ 4 observations during the study period when at least one LS was ≥ 2. For LS ≥ 1, mean prevalence was 40%, with 98.6% of cows having ≥ 4 observations during the study period when at least one LS was ≥ 1 during lactation. Hoof trimming had no apparent effect on the incidence of clinical lameness (LS ≥ 2) (trimmed vs. non-trimmed: 33.2% vs. 28.8%, respectively), but for LS ≥ 1, there was a small decrease in the incidence of LS ≥ 1 (trimmed vs. non-trimmed: 96.9% vs. 99.3%, respectively). The hazard of a cow having a first observed LS ≥ 2 in the control group was 0.87 (95% CI = 0.66-1.14) times that of the trimmed group; however, the hazard of a cow having a first LS ≥ 1 was 1.60 (95% CI = 1.37-1.88) times higher in the control than in the trimmed group. CONCLUSION AND CLINICAL RELEVANCE: On this farm, prophylactic hoof trimming had no clinically relevant impact on the incidence of clinical lameness and was not associated with clinically beneficial reductions in time to first observed LS ≥ 2. This may be because claw horn imbalance was not pronounced on this farm, with 53% of cows needing no trim on either hind limb on the first trimming occasion. Further research on the response to prophylactic trimming in pasture-based dairy cattle is required.

Perceptions of Australians with diabetes-related foot disease on requirements for effective secondary prevention.

INTRODUCTION: Secondary prevention is essential in reducing recurrence of diabetes-related foot disease (DFD) but is frequently poorly implemented in clinical practice. OBJECTIVE: To explore the perceptions of people with diabetes-related foot disease (DFD) on their self-perceived knowledge in managing DFD, facilitators and barriers influencing their DFD care, and ideas and preferences for a secondary prevention program. DESIGN: Sixteen people with a history of DFD from Queensland and Victoria, Australia, underwent semi-structured interviews. Interviews were audio-recorded over telephone and transcribed and analysed following a thematic framework. Participants were asked about their experiences and perceptions relating to DFD and factors influencing the care they receive for DFD relevant to the development of a secondary prevention program for DFD. FINDINGS AND DISCUSSION: Participants had high self-perceived knowledge in managing DFD, especially in implementing healthy lifestyle changes and conducting daily foot checks and foot care, though most received support from family members acting as carers. However, issues with access and adherence to offloading footwear, and a lack of clear education received on footwear and other aspects of DFD care were perceived as major barriers. Improved patient education, provided in a consistent manner by proactive clinicians was perceived as an essential part of secondary prevention. Telehealth was perceived positively through facilitating faster care and considered a good adjunct to standard care. Health and technological literacy were considered potentially major barriers to the effectiveness of remote care. CONCLUSION: People with DFD require improved access to offloading footwear and education about secondary prevention, which could be provided by telehealth with adequate support.

Chopped straw and coffee husks affect bedding chemical composition and the performance and foot pad condition of broiler chickens.

Bedding material is a crucial environmental factor for chickens. Coffee husks are waste from the industry that could be reused. The study aimed to analyze the chemical composition of various bedding types and assess their impact on the performance characteristics of broiler chickens and the incidence of footpad dermatitis (FPD). Ross 308 broilers were used in the study. Birds were divided into 3 groups (216 chickens, 72 per group). Group 1 was kept on chopped straw (S). Group 2 was kept on coffee husks (CHs), and the 3rd group (PB) was kept on pellet bedding made from S and CHs in a 1:1 ratio. The dry matter (DM), crude fiber (CF), nitrogen (N), phosphorus (P), potassium (K) content, and the pH of the bedding were analyzed. Production results were examined during 42 days of rearing. FPD was assessed on a point scale. The tissue composition of the carcasses and qualitative physicochemical characteristics of the meat (pH, color, water holding capacity, drip loss) and bone-breaking strength were analyzed. Straw had a higher CF content. In total, the highest N content in CHs was noticed. P content was lower in the S, and K was the highest in the CHs group, followed by S and PB. The pH of the bedding was lower in the CHs group, higher in PB, and highest in S bedding. The DM was decreasing within the days of rearing. A significant interaction was demonstrated between the type of bedding and rearing days on the bedding (manure) composition. On days 1-14, FCR deteriorated in the PB group compared to the S group. The presence of FPD was significantly lower in the PB group than in the others. In the PB group, chickens had a higher slaughter yield than in the S group and a lower weight and liver share than in the CHs group. The weight and proportion of abdominal fat were higher in the group kept on S than on CHs. It can be concluded that coffee husks as a component of pellets had a beneficial effect on reducing FPD in chickens and their slaughter yield and enriched bedding with nutrients, which with poultry manure, could be a good fertilizer for agricultural soils after rearing. It could be recommended to use pelleted bedding.

Strategic palmar trimming before conventional shoeing shows potential for managing underrun heels in horses.

Background: Underrun heels are among the most hoof imbalances, causing poor performance in hoses. Several corrective shoeing protocols have been performed, but the outcomes have yet to be consistent. In this study, we proposed an alternative trimming protocol for managing underrun heels: strategic palmar trimming before conventional shoeing. Therefore, the current study aimed to investigate the potential of strategic palmar trimming before conventional shoeing for managing hoof imbalance in horses with underrun heels. Methods: Eleven affected horses were divided into control (5 horses with 14 defective hooves) and experimental (6 horses with 16 defective hooves) groups. The experimental group underwent strategic palmar trimming before conventional shoeing, while the control horses received regular trimming before traditional shoeing. Dorsal hoof wall angle (DHWA)/heel angle (HA) ratios, heel-bulb distance, and six parallel lines indicating solar surface dimension were determined before, and after 5, 10, 15, 20, 25, and 30 weeks of the different trimming protocols. Palmar trimming distance was only measured in experimental horses. Results: A group-by-time interaction was observed for DHWA/HA ratios and solar surface dimension. Separate effects for group and time were observed in the heel-bulb distance. A modification in hoof conformation was detected at 25-30 weeks only in horses in the experimental group, including decreases in DHWA/HA ratio, heel-bulb distance, and palmar trimming distance, coinciding with an increase in palmar width of trimmed hooves. Conclusions: Different trimming protocols produced a different effect on hoof conformation. Therefore, tactical remedial trimming can potentially control poor hoof conformation in horses with underrun heels.

Preventative Care: Managing the Geriatric Horse with Integrative Therapies.

Horses 15 years of age and older now account for a significant portion of the equine population. Integrative therapies can provide important diagnostic and treatment tools for managing and maintaining the health of geriatric horses. Aged horses are often afflicted with chronic disease processes that are difficult to effectively manage with conventional medicinal approaches, such as laminitis and osteoarthritis. Diagnostic and therapeutic approaches using integrative therapies, such as acupuncture and spinal manipulation, are presented in this article for managing aged horses with metabolic disorders and musculoskeletal pain, stiffness, or muscle hypertonicity.

A proposed structural approach to improve cow-claw health on Dutch dairy farms.

Despite extensive research leading to an improved understanding of the risk factors and pathogenesis of infectious and non-infectious disorders, claw health has not structurally improved in recent decades. Several studies have shown that claw disorders harm milk production, fertility and longevity of the dairy cows and job satisfaction of the farmer. This is enough reason to structurally improve claw health on dairy farms. The focus should be on a rapid curative intervention when lameness occurs and above all the prevention of claw problems. Most claw disorder diagnoses are nowadays made during regular claw trimming by the professional trimmer or the dairy farmer. Registration of the detected disorders during claw trimming is not always done consistently, so the estimated prevalence (number of cows with a claw disorder) is in most cases an underestimation of the real prevalence. The quality of these records often makes it difficult for consultants to formulate appropriate claw health advice. To be able to give good advice on claw health, insight into the prevalence of the various hoof disorders on a farm is a key condition. However, good quality advice alone is not a guarantee for an improved claw health situation on a farm. Research has shown that in addition to high quality substantiated advice, the communication style between the consultant and the dairy farmer is essential for the interpretation and motivation of the dairy farmer to implement the advice. In this paper a 7-point plan is presented as a guidance for herd advisors who want to support dairy farmers to improve claw health.

"Feeding the Foot": Nutritional Influences on Equine Hoof Health.

Nutrition plays an important role in equine health, including that of the foot. Deficiencies and excesses of dietary components can affect the growth and function of the foot and have been associated with important podiatric diseases. The recognition, prevention, and treatment of specific notable nutritional diseases of the foot are discussed, as well as information regarding specific ingredients included in supplements meant to improve equine hoof quality. Ensuring provision of a balanced diet, maintaining horses in appropriate body condition, and seeking guidance from an equine nutritionist when creating dietary recommendations will prevent most equine foot disease related to nutrition.

Review of guidelines for functional claw trimming and therapeutic approach to claw horn lesions in cattle.

Lameness is one of the most pressing health and welfare problems in cattle, especially on dairy farms. The most common cause of lameness is claw pathology, often due to lack of appropriate functional claw trimming. Functional claw trimming restores the physiological shape of the claws and distributes weight properly between the claws and over the claw weight-bearing surface. It also allows closer examination of the claws for early signs of pathology. The methods of functional claw trimming described in the previous century are still applicable today, considering some recent findings on the subject. It is essential not to over-trim the claws and to maintain strict hygiene of the trimming tools. Claw horn pathology in the early stages is usually treated effectively by therapeutic claw trimming alone. The stoic nature of cattle and their natural tendency to hide pain often result in delayed treatment of claw diseases, leading to more advanced stages of disease/pathology associated with higher-grade lameness. This situation often leads to the development of neuropathic pain and hyperalgesia requiring multimodal treatment. Because claw horn diseases are multifactorial, veterinarians and others involved in animal management must be familiar with the preventive measures available to improve claw health in a cattle herd. Further research to improve claw horn quality and effectively control/prevent claw infections without polluting the environment or negatively affecting worker and animal health is still needed. This article reviews the latest knowledge on functional claw trimming and treatment of the most common claw horn diseases in cattle.

Cloves (Syzygium aromaticum) fluid gel on healing of pododermatitis in rabbits.

Wounds are damaging to quality life of confined animals, causing dysfunction in spinal, members injuries, and reduction in productive performance. This research investigated the clove antimicrobial and antioxidant activity on the healing of decubitus wounds (pododermatitis) of rabbits (Oryctolagus cuniculus). Adult animals were treated for 21 days every three days with a fluid gel spray in the wound region: control fluid gel without addition of clove (FGC0), fluid gel with addition of 1% clove powder (FGC1), and fluid gel with 2% clove powder (FGC2). Microbiological analysis for Escherichia coli and Pseudomonas spp. were performed during 21 days of experimental period. After this period, samples from treated skin were evaluated for histological analysis and evaluation of the healing process by spectroscopy (FTIR-ATR). Rabbits treated with FGC2 showed advanced healing and decreased tissue inflammation similar to healthy rabbits, while FGC0 rabbits showed a decrease in bacterial contamination without signs of healing. Both FGC1 and FGC2 rabbits demonstrated antimicrobial and antioxidant action against both bacteria tested, favoring the wound healing process. Considering the results, the use of fluid gel with 2% of clove powder (Syzigium aromaticum) based on the best antimicrobial, antioxidant and anti-inflammatory activities on healing of decubitus wounds (pododermatitis) of rabbits in commercial farming system.

The effects of social environment on standing behavior and the development of claw horn lesions.

The primary aim of this prospective experimental study was to evaluate how the social environment after calving influenced standing behavior in primiparous cows. At calving, primiparous cows were mixed with familiar peers in a low-stocked pen (≤33% stocking density; n = 22) or mixed with unknown older cows at 100% stocking density (n = 20). All study cows were mixed with older cows 3 wk after calving. Time spent standing and perching (standing with only the front feet in the stall) were measured d 1 to 3 after calving using 5-min scan sampling. To evaluate if the low-stocked treatment constituted a low-stress social environment, agonistic interactions at the feed barrier were measured for 90 min following feed delivery for a subsample of cows in both treatments (12 cows/treatment). The daily behavioral time budget, including the 90 min following milking, was examined for this subset of cows. A secondary aim was to assess if the social environment after calving was related to the risk of developing claw horn lesions later in lactation. Sole and white line lesions were recorded at wk 6 and 12 after calving, and cows were categorized as either having or not having at least 1 hemorrhage of severity ≥3 (scale 1 to 5) for each lesion type and assessment. Prolonged standing after regrouping was not observed, and we found no differences in standing time and time spent perching between treatments. Agonistic behaviors directed toward the focal cows occurred less frequently in the low-stocked pen compared with the control. The number and severity of sole and white line lesions increased after calving. At wk 6 postpartum there was a numeric (but not statistically significant) difference between treatments in the proportion of primiparous cows that had white line hemorrhages of severity score ≥3 (low-stress social environment: 20% vs. control: 50%). In conclusion, under the conditions of this study the social environment did not influence standing behavior, but did affect agonistic interactions and may have influenced the risk of claw horn lesions in the weeks following calving. Further studies should evaluate the relationship between the social environment and claw health.

A commentary on podiatry during the Covid-19 pandemic : Podiatry during the Covid-19 pandemic.

BACKGROUND: The arrival of the novel coronavirus (SARS-CoV-2) has impacted the many aspects of modern life, especially, in the immediate term, the delivery of healthcare. CONTEXT: This commentary examines the profession of podiatry and how it has adapted and responded to the emerging crisis. It focusses on but is not exclusive to the position in the United Kingdom (UK) and the edicts and direction from the UK Government. PODIATRY ROLES DURING THE PANDEMIC: It describes the role of podiatry in the pandemic and highlights the deployment of podiatry resources to fight the pandemic beyond traditional podiatric practice. It also looks at the shift from conventional consultation to digital solutions for managing patients in an effort to achieve the goals of maintenance of foot health whilst reducing the spread of the virus. The commentary summarises the emerging data related to a possible foot related presentation of the coronavirus. CONCLUSION: The podiatry profession proved its flexibility and adaptability during the pandemic, to adjust rapidly to ensure that patients were able to access treatment to reduce risk of infection, ulceration and amputation. Dermatological presentations on the feet have been associated with Covid-19 in adolescents as is often the case in viral infections. CPD webinars to support clinicians and manage and prevent the spread of Covid-19 have been widely disseminated along with algorithms to ensure that patients that need treatment are being treated appropriately. Podiatrists have embraced remote technology to ensure that patients are correctly and safely triaged and, signposted and given appropriate self-care advice. MSK podiatrists have the ability to play an intrinsic role within the post discharge rehabilitation pathway.

[Improvement of claw health of cattle in Switzerland]. / Verbesserung der Klauengesundheit beim Rind in der Schweiz.

INTRODUCTION: The modern technique of cattle hoof care was founded by E. Toussaint Raven in 1977. Environmental risk factors on cattle claws altered in the past 43 years. The change from free ranging to indoor housing, the intensified feeding and the breeding towards traits of high performance have significantly increased the mechanical and chemical stress on the claws. In modern free-stalls, dairy cows are required to walk on hard flooring to feed, drink and get milked. Good hoof health is a basic requirement for cattle welfare. Professional and regular hoof trimming is still considered the most effective measure to promote hoof health in dairy cattle. In order to meet today's requirements and to promote claw health, the Swiss Hoof Trimmers Association (SKV), in collaboration with the Vetsuisse faculties, Universities of Berne and Zurich, and the Bovine Health Service (RGD, Bern) developed and described the Swiss technique of functional claw trimming. The aim was to establish a consistent method, which takes into account the size and bodyweight of the modern cow, the anatomical and physiological characteristics of their claws and includes adaptations counteracting very relevant diseases such as digital dermatitis. The result is a workflow described and illustrated with coloured pictures and consisting of five individual steps based on the technique of E. Toussaint Raven, Additionally, the upcoming Swiss national resource project on long-term improvement of claw health is presented in some detail. The key point of this project is the electronic documentation of clinical findings by the trained professional claw trimmers. This data will later (i) be used to assess the foot health of Swiss cows, (ii) allow to determine the prevalence of foot diseases of cattle in Switzerland and (iii) to monitor the effect of the implementation of foot health concepts. The aim of this work is to combine the findings from science and the practical experience of hoof trimmers in one method, to standardize the applied hoof care in Switzerland and to adapt it to today's hoof health requirements.

INTRODUCTION: La technique moderne du soin des pieds des bovins et du parage des onglons a été fondée par E. Toussaint Raven en 1977. Au cours des 43 dernières années, le passage d'une détention au pâturage à une détention à l>intérieur, l'intensification de l'alimentation et la sélection vers des caractéristiques de hautes performances ont provoqué une augmentation sensible du stress mécanique et chimique exercé sur les onglons. Dans les stabulations libres modernes, les vaches laitières doivent se déplacer activement sur un sol dur pour se nourrir, boire et se faire traire. Pour cela, une marche indolore est une exigence de base. Un parage professionnel et régulier est toujours considéré comme la mesure la plus efficace pour promouvoir la santé des onglons chez les bovins laitiers. Afin de répondre aux exigences actuelles et de promouvoir la santé des onglons, l' Association suisse des pareurs d'onglons (ASPO), en collaboration avec les facultés Vetsuisse des universités de Berne et de Zurich et le Service sanitaire bovin (SSB, Bern) a développé et décrit une technique suisse de parage fonctionnel des onglons. L'objectif était d'établir une méthode cohérente, qui tienne compte de la taille et du poids corporel de la vache moderne, des caractéristiques anatomiques et physiologiques de ses onglons et qui inclue en même temps des innovations pour lutter contre des maladies très importantes telles que la dermatite digitée. Le résultat est un processus de travail composé de cinq étapes individuelles adaptées selon E. Toussaint Raven, décrites et illustrées dans un tableau avec des illustrations en couleurs. En outre, un projet de ressource nationale suisse sur l'amélioration à long terme de la santé des onglons est présenté en détail. Dans ce cadre, la documentation électronique des découvertes pathologiques faites pendant le parage des onglons par des ongleurs professionnels et formés représente le cœur de ce projet. Ces données seront ensuite utilisées (i) pour évaluer la santé des pieds des vaches suisses, (ii) pour permettre de déterminer la prévalence des maladies des pieds des bovins en Suisse et (iii) pour surveiller l'effet de la mise en œuvre des concepts de santé des onglons. Le but de ce travail est de combiner les résultats de la recherche et l'expérience pratique des ongleurs en une seule méthode, de standardiser les soins pratiqués en Suisse et de les adapter aux exigences actuelles en matière de santé des onglons.

Prognostic Factors for Drop Foot Due to Lumbar Degenerative Diseases: The Impact of Surgical Timing on Postoperative Recovery.

STUDY DESIGN: Retrospective clinical series. OBJECTIVE: To investigate the prognostic factors for the improvement of drop foot caused by degenerative lumbar disease after surgery. SUMMARY OF BACKGROUND DATA: Drop foot may be caused by lumbar spinal diseases and may affect daily life. There are limited data regarding predictors of drop foot, especially surgical timing. METHODS: We retrospectively reviewed data from 87 patients with drop foot. Prognostic factors and precise timing of surgery affecting drop foot improvement were examined by multivariate logistic regression analysis. RESULTS: Forty patients (46.0%) recovered from drop foot after surgery. Age [odds ratio (OR)=0.93; 95% confidence interval (CI), 0.87-0.98; P=0.01], preoperative anterior tibialis muscle strength (OR=12.0; 95% CI, 2.41-59.9; P=0.002), and duration of drop foot before surgery (OR=3.59; 95% CI, 1.09-11.8; P=0.04) were significant prognostic factors. Two months was the most appropriate cutoff for surgery after appearance of symptoms. CONCLUSIONS: Age, preoperative tibialis anterior muscle strength, and duration of drop foot were statistically significant prognostic factors of recovery from drop foot. Surgery within 2 months after the onset of drop foot may improve postoperative outcome.

Lower odds of sole ulcers in the following lactation in dairy cows that received hoof trimming around drying off.

Sole ulcers negatively affect production and animal welfare in dairy cows. Hoof trimming around drying off is frequently recommended, but has not previously been evaluated scientifically. The association between hoof trimming around drying off and the odds of sole ulcers in the following lactation was evaluated based on recordings from 621,228 hoof trimmings in Danish dairy herds. Overall, 6.2% of cows had sole ulcers at the first hoof trimming 0-180 days in milk. The odds of sole ulcers increased with increasing days in milk, and were approximately 20% lower in cows hoof trimmed around drying off. Odds were higher in older cows, and in cows with sole ulcers in the previously lactation. Hoof trimming around drying off may help reduce the occurrence of sole ulcers in the following lactation.
