an experiment was conducted to investigate the effect of zinc (zn) supplementation and different concentrations of calcium (ca) and phosphorus (p) in wheat-based diets on the performance, immune responses and bone parameters of broiler chickens. a randomized complete block design with factorial arrangement was used (three concentrations of zn supplementation×two concentrations of dietary ca-p),...

an experiment was conducted to determine the effect of different levels of potato replacing maizeseed on performance characteristicsand immunes system of broiler chicken in a completely randomized design. a total of 220 broiler chicks were randomly assigned to 5 treatment groups, with 4 replicates of 11 birds each. the chicks in the first group were fed basal diet (control), 2nd and 3rd groups ...

a total number of  5520 female and  480 male breeders (arbor acres plus) at 42wks of age  were used in a 10-week-trial to investigate the effect of an enzyme complex on  the quality  and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. there were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...

objective: an experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  methods: one hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. each replicate contains 15 chicks. the t...

The objective of this experiment was to evaluate the influence of glutamine (Gln) supplementation in the diet of broiler chickens on the growth performance, immune response as well as some blood parameters. Two hundred fifty one day old broiler chickens were allotted into five equal groups (50 chicks per each) of mixed sex. Five experimental diets were formulated to be isonitrogenous and isocal...

Using distillers dried grains with solubles (DDGS) as a feed ingredient in poultry nutrition has lately been increased. This study was conducted to evaluate the effect of adding different dietary levels of DDGS on the productive performance of broiler chicks from 1 to 35 d of age. Two hundred forty one-d-old broiler chicks were randomly distributed among 3 treatment groups with eight replicates...

The effects of selected herbal dietary supplements on the growth performance and carcass quality of broiler chicken were investigated. Three hundred and eight day-old, male broiler chicks of Indian River strain were randomly allotted to seven experimental diets namely negative control, 0.0125% flavomycin (positive control), 0.1% Moringa leaf powder (MLP), 0.05% Moringa leaf powder, 0.035% Zigbi...

this experiment was conducted to examine the effect of multi-strain probiotic (primalac) on performance, immune responses and cecal microflora in broiler chickens under cyclic heat stress condition. a total of 96 one-d-old mixed sex broiler chicks (ross 308) were weighed and randomly allocated to two treatment groups, each with 4 replicate pens of 12 chicks. the dietary treatments were basal di...

a 42-day study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (srbc). a total of 324 one-day-old chicks were attributed to 6 experimental groups. c: control (soybean-corn); cs1:7.5% cs; cs2:15% cs; cs-fs:10% fs + 10% cs; fs1:...

the aim of this study was to evaluate the effect of organic selenium supplementation on the immune response of broilers vaccinated against coccidiosis, infection bursal disease virus (ibdv) and newcastle diseases virus (ndv). the study included three treatments (t), t1= control (inclusion of inorganic selenium in a basal diet), t2= basal diet + 0.2 ppm of organic selenium as selenomethionine an...
