INVESTIGATION OF ACUTE STRESS IMPACT ON NURSERY PIG GASTROINTESTINAL FUNCTION AND ABILITY OF BIOACTIVE COMPONENTS OF GARLIC TO MITIGATE STRESS-INDUCED PHYSIOLOGICAL CHANGES
… nursery pig growth performance, although ileal villus height was increased. Furthermore, there was a linear increase in IL-8 and a decrease in zonula occludens 1 (ZO-1) ileal gene expression due to oral DADS + DATS administration. The optimal dosage of DATS + DATS to maximize ileal villus height …

Dietary supplementation of saccharin-based artificial sweeteners and capsicum oleoresin as a strategy to mitigate the negative consequences of heat stress on pig growth performance and intestinal physiology
… count (P<0.03), irrespective of treatment. Ileal villus height tended to decrease during HS and PFTN compared to TN (P<0.08). Duodenal and colon villus height nor duodenal, ileal and colon crypt cell depth did not differ between groups. Overall, TakTik Sweet Heat supplementation increases pig feed …

Intestinal Mucosal Mast Cell Immune Response and Pathogenesis of Two Eimeria Acervulina Isolates in Broiler Chickens
… EA1 produced duodenal lesions and reduced villus height to crypt depth ratios when compared to controls; however, no differences were found in mast cell counts. EA2 produced differing results, and observed data were suggestive of an intestinal secretory response when compared to EA1 or …

Resposta de pintainhos de corte desafiados com salmonella enteritidis e alimentados com dois níveis de treonina
… of the small intestine were processed to assess villus height, crypt depth and villus: crypt. Therefore, the high level of threonine positive influence on the histological analysis, performance and microbiology of cutting chicks infected with salmonella.

Influência da treonina sobre o desempenho e a morfometria intestinal de frangos de corte submetidos a estresse por calor de 1 a 15 dias de idade
… for histomorphometry analyses. It was evaluated villus height, crypt depth and villus:crypt ratio. Final weight and morphometry results were submitted to ANOVA and means were compared by Tukey’s test at 5% of probability. Weight gain, feed intake and feed conversion were submitted to descriptive …

Immunoprotective effects of lipopolysaccharide detoxification by a novel microbial-derived alkaline phosphatase
… and body weight. MAP-fed piglets had increased villus height and decreased crypt depth, and an increased villus height to crypt depth ratio in the duodenum, jejunum, and ileum. Furthermore, MAP-fed piglets were protected against weaning-induced downregulation of tight junction protein ZO-1 and …

The role of Dietary Interventions in Broiler Intestinal Health and Immunity
… with each mannan-rich fraction (MRF) increased villus height and villus surface area. In addition, crypt depth was increased upon dietary inclusion of naturally-derived additives. Dietary inclusion of mannan rich fraction (MRF) supplements (supplements 1 to 3) enhanced goblet cell density and …

Poultry Performance and Food Safety Impacts of Selected Organic Acids and Probiotics
… The results showed increased body weight gain, villus height, villus width, and villus surface area index in chickens treated with neonatal nutrition and/or glutamine, and a reduction in <em>Salmonella</em> incidence and nitric oxide from ileal tissues of treated groups. </p>

Effects of high incubation temperature on the developing small intestine and yolk sac of broiler chicks with insight into goblet cell development in the small intestine early posthatch
… lower body weights, lower hatchability and lower villus height in the duodenum, jejunum, and ileum. There were also differences seen in the depth of the crypt, which is the site for stem cells. Chicks from eggs incubated at a higher temperature had a lower crypt depth in the duodenum and jejunum. …

Effects of fructan source and degree of polymerization on intestinal barrier function and histomorphology characteristics in obese C57BL/6 mice
… cellulose, however, had greater (p<0.05) ileal villus height: crypt depth ratio, ileal MUC2 mRNA abundance, proximal colon AMPK mRNA abundance, and occludin mRNA abundance in the proximal and distal colon regions. When comparing fructan vs. cellulose treatments using contrasts, fructans resulted …

Effects of distillers dried grains with solubles and dietary fiber on the intestinal health of young pigs and chicks
… diarrhea (diet linear, P < 0.01) and increased villus height in jejunum of Ecoli pigs (diet linear × challenge, P < 0.001). Also in recovery, pigs fed either 5 or 10% DDGS had a larger bacterial diversity in cecum (P = 0.02) and colon (P = 0.08), than those fed 0 or 20% DDGS. When purified …
