a total of 448 ross 308 seven-day old male broiler chicks were assigned to seven treatments with four replicates, each containing 16 chicks, to determine effects of physical sizes and rate of dietary inclusion of clinoptilolite. the chicks fed diet containing clinoptilolite at 1.5% and particle size of 0.4-0.8 mm showed significantly higher body weight gain than the control group that did not r...

exogenous enzymes such as xylanase can cause recovery of efficiency in poultry. in this study we investigated the effects of xylanase supplementation on small intestine histomorphometry in broilers chicken. two levels of xylanase supplementation (with or without 0.07% xylanase) was used in 4 treatment groups (two repetitions for each group and 15 chicks per group). after 42 days, 10 chicks from...

Effect of probiotic Bioplas 2B was tested on morphologic and cecal microbial populations in quails. Experimental treatments included control; 30 mg/kg antibiotic; 0.1% probiotic; 0.05% probiotic. 320 one-day quail with four experimental treatments in four replications were used in a completely randomized design. The best feed conversion ratio (FCR) was observed in quails fed with 0.05% probioti...

This study was conducted to investigate the effects of garlic powder (GP) black seed (BS) and plant premix (GP and BS) in the diet on broiler growth performance and intestinal morphology. included 480 Hubbard broiler chicks(day-old). There were 4 treatment groups each consisting of 3 replicates. The four dietary treatments consisted of a control (basal diet), basal diet +0.5% GP, basal diet +0....

            The aim of this study was to investigate the effect of different levels of soybean meal peptides on body weight gain, feed conversion ratio, feed intake intestinal morphology and microbial population in broiler chicks. In a completely randomized design 280 one-day-old Ross 308 male broiler chicks were allocated to 7 treatments with 4 replicates and 10 chicks per replicate. Broiler c...

A modified Roux-en-Y repositioning of rat small intestine was performed so that the proximal segment of bowel (A) received only bile and pancreastic secretions, the second (B) received food direct from the stomach, and these two segments drained into a third (C). Four to five weeks after operation, cell production was assessed by injection of vincristine into operated, sham-operated and unopera...

The effects of dietary supplementation of grape seed extract (GSE) and vitamin C on carcass characteristics, gut morphology and ileal microflora in broiler chickens exposed to chronic heat stress were examined. Experimental diets included a control diet (without additive), 3 levels of GSE (150, 300, 450 mg/kg of diet), and vitamin C (300 mg/kg of diet). Each of the five diets was fed to 5 repli...

Hyaluronic acid (HA), a component of the extracellular matrix, affects gastrointestinal epithelial proliferation in injury models, but its role in normal growth is unknown. We sought to determine the effects of exogenous HA on intestinal and colonic growth by intraperitoneal injection of HA twice a week into C57BL/6 mice from 3 to 8 wk of age. Similarly, to determine the effects of endogenous H...
