background & aim: medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.this experiment was conducted to investigate the effects of milk thistle (mt) and thyme seeds (ts) on the performance in broilers. experimental: in this study, 160 one-day-old (ross 308) male broiler chicks were divided randomly into four major groups with 4 replicate...

an experiment was conducted to evaluate the efficacy of exogenous enzymes supplementation (es) on performance, carcass traits and some blood parameters of broilers chickens. one hundred and eighty day old chicks with 40 ± 2 g initial body weight in a completely randomized design with 3 treatments and 4 replications were fed experimental diets included, 1) basal diet no enzymes (control), 2) bas...

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),...

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 research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...

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 objective of the study was to compare the effects of antibiotic virginiamycin, probiotic Protexin® and Plantago major L. (plantain) on performance, serum metabolites, immune response, and the ileal microbial population of broilers. The experiment was carried out with a total of 200 day-old male Ross 308 broiler chickens in a completely randomized design. Chickens were allocated to five grou...

A randomized complete block design with factorial arrangement was used (three concentrations of Zn supplementation×two concentrations of dietary Ca-P),...

Abstract Black Soldier Fly (BSF) larvae ( Hermetia illucens ) is a feed that has high protein content. The research aims to determine the role of use BSF performance grower-phase poultry substituted fish flour. A total 120 4-week-old native chickens were alloted 5 dietary treatments and 4 replications based on completely randomized design. treatment consists P0 (basal rations + 100% flour), P1 ...
