We investigated the effects of dietary β-1,4-mannobiose (MNB) on the weights of body, breast muscles, thighs, liver, and abdominal adipose tissue in growing broiler chicks to evaluate whether MNB can be used as a feed additive for broiler chicks. A total of 24 eight day-old male broiler chicks were allocated to two cages and fed a control diet or a 0.01% MNB-supplemented diet for 14 days. Dieta...

the present study was carried out to investigate the effect of different levels of triticale with/ without enzyme cocktail (xylanase and β-glucanase) on performance of broiler chicks. five hundred day old male broiler chicks (ross 308), assigned to a factorial arrangement (5×2) with a completely randomized design with 5 replicates of 10 chicks each. the factors included 5 levels of triticale (0...

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...

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...

This study investigated the effects of coenzyme Q10 (CoQ10) supplementation on hematological, enzymes activities and biochemical parameters in broilers with pulmonary hypertension syndrome (PHS).Two hundred and forty 1-d-old Ross 308 male broiler chicks were randomly allocated into 3 groups with 4 replicates. From d 14, the diets were supplemented with CoQ10 at levels of 0, 20 and 40 mg/kg, res...

The present study was conducted to investigate the effects of dietary supplementation of chromium methionine (CrMet) on performance, immune responses, and stress status of broiler chicks subjected to heat-stress conditions. A total of 450 day-old Ross 308 broiler chicks were randomly distributed between 5 replicate pens (15 birds each) of 6 experimental treatments according to a 2 × 3 factorial...

abstract: this study was conducted to investigate the effects of diets containing different levels of hull-less barley on caecal microflora of broiler chicks. two hundred and forty one-day old male broiler chicks (arbor acres strain) were used in a completely randomized design with 4 tratments, and 3 replicates were allocated to each treatment. different levels of hull-less barley in diets had ...

Bacterial co-infections can probably influence the pathogenicity of H9N2 low pathogenic avian influenza virus (AIV). This study aimed to evaluate the effect of exposure time to Escherichia coli (O:2) on the pathogenicity of H9N2 AIV in broiler chickens. Three hundred and sixty broiler chickens were randomly allocated to six equal groups. At the age of 26 days, all chicks except groups 5 and 6 w...

Abstract This experiment was conducted at the poultry field, Agricultural Research and Experiment Station, College of Agriculture, Al-Muthanna University, from 21 February 2022 to 26 March 2022. A total 180 unsexed, 1 day old, Ross 308 broiler chicks were used, randomly distributed four experimental treatments, 45 for each treatment with three replicates (15 chicks/replicate) 35 days, treatment...
