RESUMEN

BACKGROUND: Goats are important worldwide as a source of milk, meat, fibre and hide, and as show animals and pets. HYPOTHESIS/OBJECTIVES: To document the type, signalment associations and prevalence of skin disease in a referral hospital population. ANIMALS: Case population at a university veterinary teaching hospital. METHODS AND MATERIALS: Retrospective study by searching computerised medical records of goats seen between 1 January 1988 and 1 January 2021. Key words employed were "alopecia, caseous lymphadenitis, Chorioptes, dermatitis, dermatophyte, dermatophytosis, goat, lice, louse, mange, mite, pemphigus foliaceus, Psoroptes, ringworm, seborrhea, skin" RESULTS: Of 1,488 records reviewed, 358 (24%) goats had skin disease recorded. Seventy-nine (22.1%) of 358 goats presented primarily for skin disease. The Nigerian Dwarf goat breed was at higher risk of developing skin disease (P < 0.0002). As goats aged, the odds for developing skin disease was higher [odds ratio (OR) = 1.07 per year, 95% confidence interval (1.04, 1.12)] as was the predilection for malignant skin tumours (P < 0.001). Sex was not associated with skin disease (P = 0.98). The most common clinical sign was exfoliative dermatitis, noted in 94 (26.4%) of 358 goats. The most common diagnoses were pediculosis, bacterial skin disease and squamous cell carcinoma. Less frequent diagnoses were Chorioptes spp. infestation, contagious ecthyma (orf), coronitis/interdigital dermatitis, demodicosis, dermatophytosis, Psoroptes spp. infestation, dermatophilosis and pemphigus foliaceus. CONCLUSIONS AND CLINICAL IMPORTANCE: Skin diseases are common in goats. Nigerian Dwarf goats and older goats are at greater risk of developing skin disease; Nigerian Dwarf goats had a predilection for malignant skin tumours. Clinicians should include a dermatological examination in goats regardless of the reason for presentation.

RESUMEN

BACKGROUND: Rumen juice analysis (RJA) involves analysis of a 10mL sample within minutes after sampling. However, it can be challenging to collect 10 mL of rumen juice (RJ) from some ruminants, and clinical circumstances can delay RJA. OBJECTIVES: Quantify the effect of sample volume (2, 5, 10, 50, and 100 mL), and time-to-analysis (0, 30, and 60 minutes) on RJA. ANIMALS: Cannulated cow. METHODS: Observational experimental study. Two liters of RJ were collected at 26 separate times. The samples were subdivided into 2 duplicates of each sample volume at each sampling time; and analyzed at 0, 30, and 60 minutes after collection. Rumen juice analysis included pH measurement, methylene blue reduction time (MBRT), and protozoal motility. RESULTS: The pH of 2 and 5 mL samples was significantly (P = .01) higher than the pH of 50 and 100 mL samples at all time points. The MBRT was significantly lower (faster bacterial reduction) for 100 mL samples compared to all other samples at 0 minute and to 2, 5, and 50 mL samples at 30 min. The pH and MBRT at 60 minutes were significantly higher than at 0 minute for all volumes (P < .05 and P < .01, respectively). For large protozoa, small sample volumes (2 and 5 mL) had significantly lower protozoal motility (scores of 5 and 4.5, respectively) compared to 100 mL samples at 60 minutes (score of 4; P < .05). CONCLUSIONS AND CLINICAL IMPORTANCE: Interpretation of RJA could be affected by small sample volumes and delays to analysis. Sample volumes of ≥10 mL analyzed within 30 minutes after collection are recommended.

RESUMEN

This article provides information to help US-based practitioners develop differential diagnoses for, and recognize foreign animal diseases associated with, dermatologic lesions in small ruminants. Sheep and goat pox are currently considered foreign animal diseases (in the United States) and may cause lesions similar to other endemic diseases of small ruminants including orf, ulcerative dermatosis, bluetongue, and dermatophilosis. Any cases involving unusual dermatologic lesions associated with high morbidity and/or mortality warrant reporting to governmental authorities including USDA APHIS or state regulatory veterinarians for herd or flock investigations. Vigilance on the part of livestock veterinarians and small ruminant producers is of paramount importance in preventing the entry and spread of economically devastating foreign animal diseases.

RESUMEN

BACKGROUND: Peripheral blood vessels in pigs are not easily accessible, making placement of intravenous catheters difficult. Alternative methods to intravenous administration of fluids, such as administering fluids via the rectum (proctoclysis), are warranted in pigs. HYPOTHESIS: Administration of polyionic crystalloid fluids via proctoclysis results in hemodilution changes similar to intravenous administration. The objectives of this study were to evaluate the tolerance for proctoclysis in pigs and compare analytes before and after intravenous or proctoclysis therapy. ANIMALS: Six healthy, growing, academic institution-owned pigs. METHODS: Randomized, cross-over design clinical trial, with 3 treatments (control, intravenous, and proctoclysis) with a 3-day washout period. The pigs were anesthetized and jugular catheters were placed. A polyionic fluid (Plasma-Lyte A 148) was administered at 4.4 mL/kg/h during the intravenous and proctoclysis treatments. Laboratory analytes, including PCV, plasma, and serum total solids, albumin, and electrolytes were measured over 12 h at T0 , T3 , T6 , T9 , and T12 . Effects of treatment and time on analytes were determined by analysis of variance. RESULTS: Proctoclysis was tolerated by pigs. Albumin concentrations decreased during the IV treatment between T0 and T6 (least square mean of 4.2 vs 3.9 g/dL; 95% CI of mean difference = -0.42, -0.06; P = .03). Proctoclysis did not significantly affect any laboratory analytes at any time points (P > .05). CONCLUSIONS AND CLINICAL IMPORTANCE: Proctoclysis did not demonstrate hemodilution similar to intravenous administration of polyionic fluids. Proctoclysis might not be an effective alternative to the intravenous administration of polyionic fluids in healthy euvolemic pigs.

RESUMEN

BACKGROUND: Goats are increasingly popular as both production animals and pets. The frequency of and factors associated with periparturient reproductive complications in goats are largely unreported. OBJECTIVES: (1) To report the frequency of periparturient reproductive complications in does presented to university veterinary hospitals and (2) to identify factors associated with uterine tears in the study population. ANIMALS: A total of 198 periparturient does presented to 9 university veterinary hospitals from October 2021 to June 2022. METHODS: Multicenter, cross-sectional study, with data collected from questionnaires completed by attending veterinarians. Logistic regression was used to identify factors associated with diagnosis of uterine tears. RESULTS: Ninety-three (47%) does had at least 1 periparturient reproductive complication. Periparturient complications included retained fetal membranes (n = 38, 26%), vaginal or perineal trauma (n = 33, 19%), uterine tears (n = 32, 18%), metritis (n = 22, 13%), uterine or vaginal hemorrhage (n = 8, 5%), Cesarean section complications (n = 8, 8%), and uterine prolapse (n = 1, 0.5%). A positive interaction effect was found between small breeds (Nigerian Dwarf and Pygmy) and manipulation on the farm by a layperson upon diagnosis of uterine tears (odd ratios [OR], 5.48; 95% confidence interval [CI], 1.41, 21.25; P = .01). CONCLUSIONS AND CLINICAL IMPORTANCE: Periparturient reproductive complications were common. Small breed combined with manipulation on the farm by layperson was associated with diagnosis of uterine tears. Clients should be educated that in the event of dystocia, small breed does are at greater risk of uterine tears and prompt veterinary intervention is critical.

RESUMEN

This article provides information to assist practitioners in the diagnosis, medical, and surgical management of obstructive urolithiasis in miniature pigs. The article focuses primarily on pigs managed as pets because production swine rarely undergo intensive treatment for urolithiasis. As much as possible, the information in this article is based on published literature, but given the limited number of publications addressing obstructive urolithiasis in pigs, some information is based on the authors' clinical experience. Medical and surgical management of obstructive urolithiasis of pigs is often similar to management in ruminant and small animal species, but differences in swine anatomy, handling, and temperament create unique challenges. Pigs tend to be more difficult to restrain and examine than other livestock and often require heavy sedation or anesthesia to facilitate physical examination and basic diagnostic procedures. Because pigs are monogastrics, some oral treatments used in small animals may be used effectively in pigs. Clinicians should follow AMDUCA and consult the Food Animal Residue Avoidance Databank prior to extralabel drug use because pet pigs are still considered a major food-producing species in the United States.

RESUMEN

OBJECTIVE: To characterize injuries and describe medical management and clinical outcomes of goats, sheep, and pigs treated at a veterinary medical teaching hospital for burn injuries sustained during wildfires. ANIMALS: Goats (n = 9), sheep (12), and pigs (7) that sustained burn injuries from wildfires. PROCEDURES: Medical records were searched to identify goats, sheep, and pigs that had burn injuries associated with California wildfires in 2006, 2015, and 2018. Data regarding signalment, physical examination findings, treatments, clinical outcomes, time to discharge from the hospital, and reasons for death or euthanasia were recorded. RESULTS: The eyes, ears, nose, mouth, hooves, perineum, and ventral aspect of the abdomen were most commonly affected in both goats and sheep. In pigs, the ventral aspect of the abdomen, distal limb extremities, ears, and tail were most commonly affected. The median (range) time to discharge from the hospital for goats and pigs was 11 (3 to 90) and 85.5 (54 to 117) days, respectively. One of 9 goats, 12 of 12 sheep, and 5 of 7 pigs died or were euthanized. Laminitis and devitalization of distal limb extremities were common complications (13/28 animals) and a common reason for considering euthanasia in sheep and pigs. CONCLUSIONS AND CLINICAL RELEVANCE: Burn injuries in small ruminants and pigs required prolonged treatment in some cases. Results suggested prognosis for survival may be more guarded for sheep and pigs with burn injuries than for goats; however, further research is needed to confirm these findings.

RESUMEN

OBJECTIVE To describe concentration-over-time data for ampicillin and sulbactam in the digital and systemic circulations and synovial fluid (SYN) of cattle following a single injection of ampicillin-sulbactam as a regional IV perfusion (RIVP). ANIMALS 6 healthy adult nonlactating Jersey-crossbred cows. PROCEDURES The right hind limb of each cow was aseptically prepared. A tourniquet was applied around the midmetatarsal region, and 1.0 g of ampicillin with 0.5 g of sulbactam in a combined formulation was administered as an RIVP into the dorsal common digital vein (DCDV). Blood samples from the DCDV and jugular vein and SYN samples from the metatarsophalangeal joint of the prepared limb were collected immediately before and at predetermined times for 24 hours after RIVP. One blood sample was obtained from the abaxial proper plantar vein of the lateral digit of the prepared limb 0.25 hours after RIVP. Serum and SYN ampicillin and sulbactam concentrations were determined by high-performance liquid chromatography. RESULTS Mean ± SD maximum concentration of ampicillin in SYN and serum obtained from the abaxial proper plantar and jugular veins was 1,995 ± 1,011 µg/mL, 5,422 ± 1,953 µg/mL, and 2.5 ± 1.6 µg/mL, respectively. Corresponding serum and SYN concentrations of sulbactam were lower but followed the same pattern over time as those for ampicillin. Synovial fluid ampicillin concentration remained above 8 µg/mL for a mean time of 18.9 hours. CONCLUSIONS AND CLINICAL RELEVANCE Potentially therapeutic concentrations of ampicillin were achieved in regional serum and SYN samples; SYN concentrations remained at potentially therapeutic values for > 12 hours following RIVP of 1.5 g of ampicillin-sulbactam in the hind limb of healthy cows.

RESUMEN

A 5-week-old Holstein heifer calf presented for emergency treatment of signs referable to gastrointestinal disease and hypovolemic shock. Fluid resuscitation uncovered clinical signs of primary cardiac disease and echocardiography revealed multiple congenital cardiac defects. Malformations included a cleft anterior mitral valve leaflet resembling an isolated cleft mitral valve and an apically-located muscular ventricular septal defect. The echocardiographic and postmortem findings associated with these defects are presented and discussed in this report.
