The aim of the present study was to evaluate the effects of canola bioactive peptides (CBP) produced by enzymatic hydrolysis of canola meal on performance, digestive enzyme activity, nutrient digestibility, gut microflora and intestinal morphology of broiler chickens. A total of 250 one-day-old Ross 308 male broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates of 10 ...

this study was carried out to investigate the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, intestinal morphology and ileal digestibility of nutrients in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and 4 replicates with 12 chicks per each replicate in a completely randomiz...

This study investigated the effects of dietary supplementation with rosemary complex powder on growth performance native chickens. In total, 180 one day-old chicks were assigned to three groups (60 birds each). The control group (Group A) received basal diet. addition diet, two experimental diets (Groups B and C) supplemented 0.2% 0.4% powder, which contained leaves, sweet basil, pineapple sage...

an experiment was conducted to evaluate the effect of non-starch polysaccharides of barley supplemented with multi-enzyme on growth performance and physiological characteristics of broilers. a total number of 375 one day old ross-308 broiler chickens were allocated randomly to 3 treatments with 5 replicates at 2 rearing period (including 1 to 21 and 22 to 42 days of age) using a crd statistical...

the objective of this study was to determine the effects of 8 levels of threonine (0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 and 1.1%) and 2 levels of protein (17.5 and 20.5%) on growth performance, gut sizes and morphology as well as to estimate standardized ileal digestible (sid) thr requirements in ross 308 males at 0 to 21 days of age. chicks were randomized into 64 battery cages (5 chicks per ...

Intestinal crypts are invaginations in the connective tissue of the human intestine and are supposed to be the site in which tumors originate, starting from the alteration of certain genes and pathways [1]. Considering that, so far, only a partial characterization of the key features of intestinal crypts has been accomplished, the in-depth investigation of their structural and dynamical propert...

this experiment was performed in order to determine effects of different levels of dietary l-threonine supplementation in male japanese quails’ diets on immune response, small intestinal morphology, blood parameters and microflora.one hundred and forty four, 1-d old japanese quails have been selected and randomly distributed between six treatments and four replicates. basal ration was based on ...

Objective measurements of various histological features in rectal biopsy material were made using computerised interactive image analysis. Analysis of the resulting data by forward stepwise discriminant analysis showed that biopsies from patients with ulcerative colitis and infective diarrhoea could be distinguished from each other and from normal biopsies; they could not, however, be distingui...

The purpose of this research to study histological and histochemical characteristics the jejunum in broiler Ross – 308 chicks. A total 120 commercial eggs (Ross-308) were used conduct research, with embryos chicks ranging age from (11,15,21) pre hatch (7,14,21) post ,The samples stained using Hematoxylin-Eosin, Periodic Acids Schiff (PAS), Alcian Blue (AB pH-2.5), Masson’s Trichrom , measure le...

The consequences of feeding a protein-free (PF) diet, as compared to casein, on gut characteristics were studied in slightly energy-restricted rats fed similar amounts of feed for 10 d. The weight and pH of fresh digesta in the stomach were lower (P = 0.045 and P = 0.016). However, the weight of fresh digesta in the other segments and gut tissue weight were not significantly affected by the die...
