Impact of intestinal bacteria on the anatomy and physiology of the intestinal tract in the PRM/Alf mouse model
… of the lamina propria, villus length and crypt depth [1]. Gut microbiota-derived factors have been proposed to also play a role in the development of a 30 % longer intestine, that is characteristic of PRM/Alf mice compared to other mouse strains [2, 3]. Polyamines and SCFAs produced by gut …

Effects of fructan source and degree of polymerization on intestinal barrier function and histomorphology characteristics in obese C57BL/6 mice
… 10% cellulose led to greater (p<0.05) intestinal crypt depth in all intestinal regions, except the distal colon. Mice fed 5% vs. 10% 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 …

A Forty-Nine Day Evaluation of Bio-Mos® Replacement of Roxarsone in a Commerically Based Broiler Feeding Program
… to 49 than challenged birds (P < 0.05). Jejunal crypt depth was increased in challenged broilers compared to non-challenged broilers at 28 days-of-age (P < 0.05). From day 0 to 35, ROX birds had lower BWG and FI than BIO and BIO+LAC birds (P < 0.05), while FCR was similar. Supplementing roxarsone …

Efficacy of exogenous phytase and protease enzymes on performance and gastrointestinal health in broiler chickens
… to the diet increased the duodenal villi length: crypt depth from 8.20 (PC) to 10.75 and 10.79 (Trt1 and Trt3, respectively). No differences in this ratio were noted between PC and the NC diets. The addition of phytase, alone and in combination with a protease, increased the available nutrient …

Impact of Dietary Proteins on Growth Performance, Intestinal Morphology, and mRNA Abundance in Weanling Pigs
… the sub-sanitary pens. In the duodenum, reduced crypt depth with Cu supplementation (P < 0.01) and a trend for greater villous length with SDPP supplementation (P = 0.09) were observed. Pigs reared in the sub-sanitary pens had lower ADG (P < 0.05) as well as shorter villous length and less crypt …

The Role of OSTalpha/beta in Bile Acid and Lipid Metabolism
… mass predominantly in ileum, villus width and crypt depth, and villus epithelial cell number. Fxr deficiency in Osta-/- mice reversed the increase in intestinal length, but not the increases in small bowel mass or villus hyperplasia. Fxr deficiency in Osta-/- mice was associated with decreased …

Intestinal Mucosal Mast Cell Immune Response and Pathogenesis of Two Eimeria Acervulina Isolates in Broiler Chickens
… 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 controls. In …

OVEREXPRESSION OR REDUCED BIOAVAILABILITY OF VEGF DURING MOUSE POST-NATAL INTESTINAL DEVELOPMENT ALTERS THE PROLIFERATION OF INTESTINAL STEM CELL PROGENITOR CELLS
… the transit-amplifying zone with the decrease of crypts per measured length and <em>Lgr5</em> expression. On the other hand, sFLT-1 overexpressing mice had an increase in crypt depth with a decrease in villus height, proliferation in the transit-amplifying zone, crypts per measured length and …

Effects of dietary feed additives on the performance and gastrointestinal health of broilers exposed with coccidial spores and varying litter conditions
… reliance. The second chapter provides an in-depth literature review on coccidiosis, alternative feed additives, and factors influencing litter quality. In the third chapter, the combination of essential oils and betaine was effective in mitigating the effects of coccidiosis. Broilers …

Supplementation of Avizyme1502 to corn/SBM/wheat diets fed to turkey tom poults from 0-56 days of age
… 1A, 2A, 3A, 4A, 5A, A and B. Villus height and crypt depth did not respond to dietary treatment, though a significant interaction of age and villus height occurred. Villus heights were similar during periods A and B; however, from period B to C, villus height dramatically increased in the PC …

Immunoprotective effects of lipopolysaccharide detoxification by a novel microbial-derived alkaline phosphatase
… 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 inflammation-induced …

Isoquinoline alkaloids in diets for young growing pigs improve nutrient digestibility and gut health
… increased (P < 0.05) in phase 1. In the ileum, crypt depth and lamina propia thickness decreased (quadratic; P < 0.05) and there was a tendency for the villus height: crypt depth ratio to increase (linear; P < 0.10). Neutrophil infiltration tended to increase in the jejunum and decrease in the …

The Effects Of Microencapsulated Vitamin And Trace Mineral Premixes And Red Osier Dogwood Extract On Growth Performance, Immune Response, And Gut Health Of Broiler Chickens In A Coccidiosis Vaccine Challenge Model
… in superior villus height and villus height-to-crypt depth ratios compared to the higher dose. The second study utilized 560 Ross 308 broilers to examine the effects of microencapsulated vitamin and trace mineral premixes. Dietary treatments consisted of a corn-soybean meal basal diet …

The role of Dietary Interventions in Broiler Intestinal Health and Immunity
… 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 mucus layer thickness. Incorporation of mannan-rich …

Effects of dietary enzyme supplementation on performance, bone ash, small intestinal morphology, and apparent ileal amino acid digestibility of broilers exposed to a live coccidia oocyst vaccine
… increased (P ≤ 0.05) small intestinal crypt depth and reduced (P ≤ 0.05) goblet cell numbers in EXP 3. Phytase supplementation of the NC diets fed to vaccinated broilers ameliorated the reduction in ileal goblet cells associated with vaccination (EXP 3). Enzyme supplementation tended to …

Characterising dysbiosis in Alzheimer’s disease utilising the APP/PS1 mouse model
… was a decrease in goblet cells in the villi and crypts of the ileum. A three-month age group was introduced which was found to have a significant difference in the mucosal- associated microbiota in the caecum of APP/PS1 mice. The dysbiosis was accompanied by a significant decrease in crypt depth …
