this study was conducted to investigate the effect of bacillus subtilis and licheni formis on broiler breeder performance and gastrointestinal health of their progenies. a total of 336 broiler breeder hens (cobb 500) from 22 to 32 weeks of age were used in a completely randomized design of 2 × 2 factorial arrangement with four treatments, each with seven replicates. dietary treatments included:...

This research was conducted to investigate the effect of inclusion of wheat bran (as a source of insoluble fiber) in a barley-based diet, fed from 11 to 42 d of age, on villus morphology of jejunum, serum cholesterol level, abdominal fat pad and growth performance of broiler chickens. Three hundred and thirty six 10-d-old female Ross 308 chicks were allocated to six diets with four replicates o...

an in vivo experiment was conducted to study the effects of probiotic bacillus coagulans spores, with and without prebiotic, inulin, on gastrointestinal (gi) microbiota of healthy rats and its potentiality to survive in the gi tract. forty-eight male wistar rats were randomly divided into four groups (n=12) and fed as follows: standard diet (control), standard diet supplied with 5% w/w long cha...

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....

 This study was carried out to investigate the apparent digestibility coefficients (ADCs) value of protein, amino acid and energy and body amino acid composition of rainbow trout fed solvent extracted soybean meal (SBM) and full-fat soybean meal (FFS) partly replacing fish meal (FM) in diets. Five iso nitrogenous (average 50.36% crude protein) and energetic (4294 kcal/kg total energy) diets wer...

this experiment was conducted to investigate the effects of using protexin, propionic acid growth promoters, and a blend of them on broilers performance. in a completely randomized design, three hundreds and twenty unsexed 1-d-old chicks were divided into four groups. dietary treatments were consisted of 1) control diet without any supplement, 2) the control diet + 0.01 % protexin, 3) the contr...

The main goal of this study was to evaluate the possible effect of whole-body magnetic field (MF) exposure on the variations of corticosterone, Free-T3, Free-T4 and malonyl dialdehyde in plasma in 48 adult white New Zealand male rabbits. Animals were divided into six groups namely, C1 (normal diet, not exposed), C2 (normal diet, sham exposed), T1 (normal diet, exposed to electromagnetic field),...

Few studies have investigated the effect of exercise on homocysteine and 15-F21-isoprostane in animal models. The present study was designed to examine the effect of long-term exercise and/ or high cholesterol diet on MDA, 15-F21-isoprostane and total homocysteine in the aorta and plasma of rabbits. Methods: 56 male rabbits were divided into four groups: normal diet (control), normal diet wi...
