effect of probiotic (clostat) levels on the performance and immune response of heat stressed broilers, was evaluated in a completely randomized design on 144 day-old male ross broiler chicks with four treatments and four replicates (nine birds each). experimental diets were consisted in four levels of probiotic (0, 0.05, 0.1 and 0.2). birds were raised under normal condition till 25 days of age...

to study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). all treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called t1, 2t, t3 and t4 that were ad...

The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...

introduction & aim: the aim the present study is to examine the effects of boswellia serrata triana & planch on (immune response) performance and carcass characteristic in broiler chicks.  experimental: in this study, 360 one day old chicks (ross 308) were allocated to six treatments with four replicates in a completely randomized design for a six week period. treatments consisted of t...

The aim of the current study was to evaluate the effects of lavender (Lavandula angustifolia) powder as an herbal feed additive on growth performance, carcass traits, meat quality, jejunal histomorphology, and ileal microbial population in broiler chickens. A total of two hundred twenty one day-old male broiler chicks were used in a completely randomized design with five treatments and four rep...

A completely randomized design experiment was conducted to determine the effects of physical form of the diet (pellets or mash) on the growth performance and water intake of broiler chicken. Twenty seven days-old (n=32) broiler chicks were randomly allocated into 8 deep litter cages. Each cage housed 4 birds and contained a feeder and a drinker. Birds in four cages were fed a commercial broiler...

One thousand and eight unsexed one day-old broiler chicks (Ross-308) were randomly divided into 3 treatment groups of 336 birds each, consist of control and two essential oil mixtures (EOM) at level of 24 mg/kg and 48 mg/kg diet. There were not significant effects of dietary treatments on body weight gain of broilers at 21 and 42 days of age. On the other hand, there were significant difference...

the effect of feeding different protein profiles on growth performance, carcass components and nitrogen content of litter in cobb 500 broiler strain was evaluated using 800 chicks in a completely randomized design with four treatments, five replicates groups of 40 birds per each treatment. the treatments were consisted of four protein feeding profiles (based on cobb strain nutrition guide, reco...

This study was conducted to evaluate the effects of dietary supplementation with cinnamon powder, cinnamon oil, and synbiotic as growth promoter agents on growth performance, blood parameters, and intestinal microbial populations in Japanese quails. A total of 420 one-day-old Japanese quails were randomly assigned to 7 treatments with 4 replicates. The dietary treatments consi...

BACKGROUND:Herbal methionine can be compared relative toDl-methionine with evaluation of bioavailability of this source ofmethionine. OBJECTIVES: An experiment was carried out todetermine the relative bioefficacy of herbal methionine (H-Met)®relative to DL-methionine (DL-Met) on performance criteria andimmunocompetence of Met sources in male broilers. Atotal of 160male broilers were fed a Met-d...
