RESUMO
OBJECTIVES: Constipation is the infrequent or difficult emission of hard, dry faeces and is a common digestive condition in cats. Psyllium is a low-fermentable fibre, with soluble and insoluble components and water-holding properties. It forms a mucilaginous gel with water and is used for the symptomatic treatment of constipation in various species. This study evaluated the effect of dietary psyllium on faecal characteristics in cats. METHODS: Healthy neutered adult cats (six female and three male, aged 3.3-4.4 years) were consecutively fed a dry extruded diet containing either 6% psyllium (test) or 6% cellulose (control) for 10 days each. During the last 3 days (the collection days) of both feeding periods, bowel movements and faecal scores were recorded, and faeces were collected to measure wet weight and moisture. The statistical analysis used linear mixed models with diet, day and their interaction as fixed effects and animal as a random term. RESULTS: The test diet was associated with significantly more bowel movements per day over 3 days (P = 0.0052) and on collection day 2 (P = 0.0229) than the control diet. The mean faecal score was higher (softer faeces) over all three collection days (P <0.0001) and on collection days 1, 2 and 3 (P = 0.0011, P = 0.0349, P = 0.0003, respectively) for the test diet vs the control diet; the total faecal wet weight (P = 0.0003) and faecal moisture (%) were also higher (P = 0.0426) for the test diet. Faeces associated with the test diet often had a dry shell and soft interior, which increased the faecal score. CONCLUSIONS AND RELEVANCE: Psyllium promoted more bowel movements and higher faecal moisture and faecal score in healthy cats, consistent with a previous uncontrolled clinical trial in constipated cats. Together, the studies support the use of dietary psyllium for managing cats with constipation.

In the modern swine industry, inflammation and pain in sows after farrowing represent a crucial animal welfare concern. Cannabis sativa, a medicinal plant, has analgesic, anti-inflammatory and antipyretic properties and is rich in fibre. The objective of this study is to examine the impacts of supplementing sows with Cannabis sativa byproducts during transition periods (7 days before and after farrowing) on various aspects including postpartum behaviour, feed intake, constipation, farrowing duration, colostrum yield and piglet performance. The experiment involved a total of 100 Landrace × Yorkshire sows. The sows were distributed according to parity numbers into two groups, i.e., control (n = 54) and treatment (n = 46). The control group was provided with a lactation diet at 3.0-3.5 kg per day for a period of 7 days before and after farrowing. The treatment groups received the same quantity of the diet but with an additional supplementation of 150 g/d of Cannabis sativa byproduct. The byproduct was analysed and contained 0.24 % (w/w) cannabidiol (CBD), resulting in a daily intake of 360 mg of CBD per sow. The conventional lactational diet had a dietary fibre content of 4.3 %, whereas the diet supplemented with Cannabis sativa byproduct had a higher dietary fibre content of 16.9 %. Video cameras were used to observe and document the behaviour of sows within the initial 24 h after farrowing. The duration in which sows engaged in activities such as sleeping, sitting, standing, feeding and nursing their piglets was quantified. Additionally, the rectal temperature of the sows was measured, and a temperature equal to or exceeding 39.5 °C was considered indicative of fever. The faecal score of the sows was assessed, and a faecal score of ≤2 was classified as constipation. On the third day postpartum, the proportion of sows with fever in the treatment group was lower than that in the control group (20.0 % and 38.9 % respectively, P = 0.051). Sows receiving supplementation with Cannabis sativa byproducts exhibited increased durations of standing and feeding compared to those in the control group (P < 0.05). Notably, overall, sows without constipation issues spent more time consuming feed than those experiencing constipation (P = 0.006). The prevalence of constipation was significantly lower in the treatment group compared to the control group (17.4 % and 81.5 %, respectively, P < 0.001). Furthermore, the postpartum sows demonstrated increased feed intake following supplementation with Cannabis sativa byproducts (P < 0.05). Sow colostrum yield, piglet colostrum intake, piglet mortality and other piglet traits did not differ between the control and treatment groups (P > 0.05). In conclusion, supplementing Cannabis sativa byproducts during the transition periods in peri-parturient sows under tropical conditions resulted in a reduction in constipation issues and improved sow activities, such as increased time spent standing and consuming feed within the first 24 h postpartum.

Constipation and systemic inflammation are common in late pregnant and lactating sows, which cause health problems like uteritis, mastitis, dystocia, or even stillbirth, further influencing piglets' survival and growth. Probiotic supplementation can improve such issues, but the beneficial mechanism of relieving constipation and enhancing gut motility remains underexplored. This study aimed to investigate the effects and mechanism of probiotic supplementation in drinking water to late pregnant sows on constipation, inflammation, and piglets' growth performance. Seventy-four sows were randomly allocated to probiotic (n = 36) and control (n = 38) groups. Probiotic treatment significantly relieved sow constipation, enhanced serum IL-4 and IL-10 levels while reducing serum IL-1ß, IL-12p40, and TNF-α levels, and increased piglet daily gain and weaning weight. Furthermore, probiotic administration reshaped the sow gut bacteriome and phageome structure/diversity, accompanied by increases in some potentially beneficial bacteria. At 113 days of gestation, the probiotic group was enriched in several gut microbial bioactive metabolites, multiple carbohydrate-active enzymes that degrade pectin and starch, fecal butyrate and acetate, and some serum metabolites involved in vitamin and amino acid metabolism. Our integrated correlation network analysis revealed that the alleviation of constipation and inflammation was associated with changes in the sow gut bacteriome, phageome, bioactive metabolic potential, and metabolism.

Synbiotic dietary supplements, as an effective means of regulating the gut microbiota, may have a beneficial effect on constipation. This study evaluated the effects of synbiotic yogurt containing konjac mannan oligosaccharides (KMOS) and Bifidobacterium animalis ssp. lactis BB12 (BB12) on constipated Kunming mice (the model group). Following administration of yogurt containing 2.0% KMOS and BB12 (YBK2.0), black fecal weight and number and gastrointestinal transit rate increased by 97.5, 106.3, and 55.7%, respectively, compared with the model group. Serum levels of excitability neurotransmitters (motilin, substance P, and acetylcholine) in the YBK2.0 group were increased by 139.7, 120.4, and 91.8%, respectively, and serum levels of inhibitory neurotransmitters (vasoactive intestinal peptide, nitric oxide, and acetylcholine) were decreased. Moreover, synbiotic yogurt supplementation significantly downregulated the expression of vasoactive intestinal peptide receptor 1 (VIPR1) and upregulated the expression of serotonin receptor 4 (5-HT4) in the colon, and enhanced the expression of the stem cell factor (SCF)/c-Kit pathway. Additionally, YBK2.0 treatment significantly regulated the community composition and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of gut microbiota, which were positively correlated with physiological parameters of constipation. Thus, supplementation with synbiotic yogurt composed of KMOS and BB12 could facilitate fecal excretion by regulating related pathways and the gut microbiota. These findings demonstrated that the synbiotic yogurt can be considered a functional food for alleviating constipation.

OBJECTIVES: Constipation is a common complaint in cats presenting to the emergency room and can become a frustrating recurrent condition. Despite widespread anecdotal reports of risk factors for constipation, at the time of writing there have been no studies supporting these associations or assessing treatment outcomes. The aim of this study was to identify risk factors in the signalment, history, physical examination and clinicopathologic findings of cats presenting to the emergency room for constipation. In addition, we aimed to assess factors contributing to the success or failure of enemas administered to these cats. METHODS: A medical record search identified 189 cats with a diagnosis of constipation/obstipation that were treated and discharged by the emergency service at an academic veterinary hospital. Data regarding signalment, medical history, physical examination and clinicopathologic findings, as well as treatments performed, were recorded. Ninety-nine cats presenting to the emergency room for other reasons were identified as controls. Statistical analysis was performed to assess risk factors for constipation, as well as success/failure of enema treatments. RESULTS: Older, overweight cats and cats with chronic kidney disease or previous episodes of constipation were found to be at increased risk of constipation (P <0.0001, P = 0.0004, P = 0.0046 and P <0.0001, respectively). Ionized calcium levels were significantly higher in constipated cats, though varied significantly within the cohort (P = 0.0133). Cats noted to be painful on abdominal palpation were less likely to defecate following an enema. Adjunctive treatments (fluids, laxatives) increased the likelihood of a successful enema but were not statistically significant. CONCLUSIONS AND RELEVANCE: Older, overweight cats with a history of constipation or chronic kidney disease are more likely to present for constipation. Further studies are needed to determine the most appropriate treatment protocol in an urgent care setting.

Chronic constipation (CC) and idiopathic megacolon (IMC) occur frequently in cats. The aim of the study was to investigate the effects of a multi-strain probiotic (SLAB51™) in constipated cats (n=7) and in patients with megacolon and constipation (n=3). Ten pet cats with a diagnosis of chronic constipation, non-responsive to medical management received orally 2×1011 bacteria daily for 90 days. For microbiota analysis, selected bacterial groups were analysed by qPCR. Histological samples in megacolons were evaluated for interstitial cells of Cajal (ICC), enteric neurons, and neuronal apoptosis. Biopsies were compared at baseline (T0) and after the end of treatment (T1), and with those obtained from healthy control tissues (archived material from five healthy cats). Constipated cats displayed significantly lower ICC, and cats with idiopathic megacolon had significantly more apoptotic enteric neurons than controls. After treatment with SLAB51™, significant decreases were observed for feline chronic enteropathy activity index (FCEAI) (P=0.006), faecal consistency score, and mucosal histology scores (P<0.001). In contrast, a significant increase of ICC was observed after probiotic therapy. Lactobacillus spp. and Bacteroidetes were increased significantly after treatment (comparing constipated cats before and after treatment, and control healthy cats to constipated cats after treatment), but no other differences in microbiota were found between healthy controls and constipated cats. Treatment with SLAB51™ in cats with chronic constipation and idiopathic megacolon showed significant clinical improvement after treatment, and histological parameters suggest a potential anti-inflammatory effect of SLAB51™, associated with a reduction of mucosal infiltration, and restoration of the number of interstitial cells of Cajal.

Two field trials, involving 66 cats (15 trial 1; 51 trial 2) were conducted to assess the efficacy of a psyllium-enriched diet for management of constipation in cats. After investigations and faecal evacuation (by enema if required), all cats were fed on a moderate fibre, psyllium-enriched, dry extruded diet. Additional therapy was either not used (trial 1), or initially allowed but was subsequently withdrawn if possible (trial 2). The diet was well tolerated, and palatability was excellent. Most cases improved after initial therapy (at 2 months; trial 1: 14/15 [93%]; trial 2: 42/51 [82%]), and faecal consistency improved significantly in both trials (P < 0.001). Use of cisapride and lactulose decreased significantly in trial 2 (P < 0.001 for both). The diets used in these pilot studies were efficient in the management of recurrent feline constipation. Randomised control trials are now recommended to examine whether a clinical benefit can be proven.

A high frequency of constipation was observed in calves with an average body weight of 150 kg. Eleven out of 200 animals died, at necropsy intestinal obstruction was identified due to agglomeration of stone like particles, identified as shell fragments of palm kernels. The calves were fed 3 kg maize silage, 1.5 kg of a commercial mixed feed, 0.5 kg soya meal, and 50 g of a mineral supplement. Hay was offered ad libitum, all animals had free access to drinking water. The composition of the mixed diet was estimated by microscopy and was completely different from the label as provided by the manufacturer. A palm kernel product with high amounts of stone shells was identified in a concentration of 25% of the mixed feed, confirming the findings in the necropsied calves. The pathogenesis of the obstruction seemed to be influenced by a concurrent infectious disease, which might have had negative effects on the gastro-intestinal motility.
