Intestinal structure of male adult African Green monkeys (Cercopithecus aethiops ssp vervets) was studied after 3'/2 yr of consuming diets containing 10% psyllium husk or cellulose. Scanning electron microscopy (SEM) identified mild damage (cellular swelling and disarray, and microvillar denudation and disarray) at villous tips throughout the small intestine in the psyllium-fed monkeys. The cel...

Different challenges are being applied in the poultry industry order to protect animal health and increase immunity production. The supplementation of microbial phytase is essential terms both reducing inorganic rate contributing absorption other minerals. In this study, a newly isolated was added at different concentrations diet together with calcium (Ca$^{2+}$) available phosphorus (AP), effe...

this experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. one hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

Copper-bearing montmorillonite (Cu-MMT) was produced by Cu cation exchange reaction. X-ray diffraction analysis showed that that the (001) basal spacing of the MMT crystal lattice increased from 1.544 to 1.588 nm after Cu exchange. This indicated that Cu entered into interlayer position of MMT as a hydrated cation or composite cation. In vitro results indicated that CuMMT had antibacterial acti...

This study was conducted to evaluate the effects of phytogenic additive and antibiotic growth promoter in laying Japanese quails. One hundred and sixty five quails were divided into three groups of 5 replicates and 11 quails (8 females and 3 males) in each replicate. Treatment 1 was fed control diet, treatment 2 was fed control diet supplemented with 0.05% bacitracin methylene disalicylate as a...

Castrated male Iberian (n = 12) and Landrace × Large White (n = 12) pigs were used to study histological structure and enzymatic activity in the small intestine at 3 points of the productive cycle (BW = 15, 50, and 115 kg). Both strains were fed the same cereal-based diets (DE = 2,799 kcal·kg(-1), and CP = 15%) throughout the entire experimental period. Differences (P < 0.05) in histometrical v...

Intestinal damage in malnutrition constitutes a threat to the survival of many thousands of children globally. We studied children in Lusaka, Zambia, with severe acute malnutrition (SAM) and persistent diarrhea using endoscopy, biopsy and analysis of markers and protective proteins in blood and intestinal secretions. We carried out parallel investigations in apparently healthy adults, and analy...

Angiotensin converting enzyme (ACE) has been shown to be involved in regulation of apoptosis in nonintestinal tissues. This study examined the role of ACE in the modulation of intestinal adaptation utilizing ACE knockout mice (ACE-/-). A 60% small bowel resection (SBR) was used, since this model results in a significant increase in intestinal epithelial cell (EC) apoptosis as well as proliferat...

This experiment was conducted to investigate dietary putrescine effects on broiler performance. Treatments were 6 levels of putrescine (0, 0.01, 0.02, 0.03, 0.04 & 0.05 %) added to a basal diet and fed to 4-32 day old broilers. The weekly growth performance was recorded, and ileal digesta and small intestine samples were collected at the end of the 2nd and 3rd week of age. At 21 d, body weight ...

A feeding trial was conducted on broiler chickens to study the effects of the synbiotic BIOMIN IMBO [a combination of Enterococcus faecium, a prebiotic (derived from chicory) and immune modulating substances (derived from sea algae)], with a dose of 1 kg/ton of the starter diets and 0.5 kg/ton of the grower diets on the intestinal morphometry and nutrient absorption. The general performance was...
