the effects of different levels of whole cottonseed (wcs) on feedlot performance and morphology of small intestine were studied in a completely randomized design with four diets containing 0, 4, 8 and 16 percent wcs on 20 chaal male lambs for 90 days. the metabolisable energy and proteins contents of rations were equal. number and dimensions of different types of villi and depth of crypt gland ...

Lysozyme is often used as a feed additive and acts as an antimicrobial protein that enhances immune function and defends against pathogenic bacteria in pigs. In this study, we genetically added recombinant human lysozyme (rhLZ) to sow milk by somatic cell nuclear transfer and investigated whether the presence of recombinant human lysozyme can influence intestinal microbiota and morphology in su...

In the present study, chicory root powder (CRP) as growth promoter at 1% and 3% levels was supplemented in broilers' diet to investigate the growth performance and histomorphometry of jejunum. One hundred twenty, one-day-old male broilers were used in a completely randomized design (CRD) with 3 treatments and 4 replicates (10 chicks per replicate). At the end of each period (0-10, 11-24 and 0-2...

Objective: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks.  Methods: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks. Results: The results of experiment 1 indicated that there were no significant differences between earthw...

BACKGROUND/AIMS The combination of starvation and surgical trauma induces disturbances to the intestinal mucosal structure and function, as well as changes in mucosal barrier function in the rat small bowel. The aim of the present study was to evaluate the effects of nimodipine administration, on intestinal mucosal structural changes and enterocyte apoptosis, following laparotomy and subsequent...

this study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. in this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (galt) in chicken were selected. one hundred an...

this study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, ph value of gastrointestinal (gi) tract and small intestinal morphology of laying hens. the experiment was a completely randomized design with 160 laying hens strain (w-36) from 32 to 42 weeks of age, with five treatments, four replicates an...

This study investigated the role of acteoside in the amelioration of mucositis. C57BL/6 mice were gavaged daily with acteoside 600 μg for 5 d prior to induction of mucositis and throughout the experimental period. Mucositis was induced by methotrexate (MTX; 12.5 mg/kg; s.c.). Mice were culled on d 5 and d 11 after MTX. The duodenum, jejunum, and ileum were collected for myeloperoxidase (MPO) ac...
