The objective of this study was to determine the effect of different levels of chicory root and stem powder (CRSP) and butyric acid (BA) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. Two hundred and forty one-day-old broilers (Ross 308) were used in a completely randomized design with four treatments with six re...

We determined the effects of dietary supplementation of different doses of Miswak (Salvadorapersica) steam and leaf powder on the performance, blood parameters, cecal flora, and carcass traits of broilers. Four hundred and eight one-day old Ross 308 broiler chicks were provided one of the following experimental diets over 42 days:  a basal diet without any additives, or a basal diet supplemente...

introduction antibiotic feed additives have long been used as growth promoters in poultry nutrition. however, concern has been expressed about the potential development of antibiotic resistant bacteria (25). consequently, the animal feed industry, exposed to increasing consumer pressure to reduce the use of antibiotic growth promoters in poultry diets, has to find alternative feed additives. ma...

The purpose of this study was to investigate the effects of diet supplemented with different levels of phytosterols (PS) on growth performance and lipid metabolism in broilers. A total of four hundred 1-day-old chicks (female: male =1:1) were randomly assigned into 4 treatments, each of which replicated 5 times with 20 chicks per replicate. Birds were fed with a basal diet without any additive ...

the effect of feeding barley-based diets (%60) supplemented with four commercial enzymes containing xylanase and ?-glucanase activities were investigated on performance and gastrointestinal size of broiler chicks. the enzyme supplemented diets were compared with unsupplemented barley- or corn-based diets. a total of 234-day-old male broiler chicks (ross 308) were allocated to 6 treatment groups...

The present study was aimed at studying the effects of inclusion of pomegranate seed extract to fat-containing diets on nutrients digestibility, intestinal microflora and performance of broilers. A total of 320 one-day-old broiler chicks (Ross 308) were selected in a 2 × 2 × 2 factorial experiment in a completely randomized design with 4 replicates o...

this experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. for doing this experiment, 320 one-day old chicks of the cobb 500 strains, in a completely randomized design with 4 treatments and 4 replicates were used. experimental diets include: control diet (without the guggul), control die...
