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....

the effect of different levels of dried purslane powder (dpp) in broiler diets on performance, immune response and some of blood factors was studied with 160 one day old chicken ross 308 in a completely randomized design with four treatments (diets included with levels zero (control), 2.5, 5 and 7.5 percent dpp), four replicates and 10 chicks in each replication. at 22-42 and 1-42 days differen...

The objective of this study was to evaluate whether the adverse effects of high dietary rice bran (RB) inclusion levels on the feed intake, performance, bone status and nitrogen (N) retention of broilers could be mitigated by wet feeding. Giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

There are many studies on the effects of probiotics on performance of broiler chickens, but none of them has evaluated the metabolizable energy (ME) equivalency values of probiotics. The aim of this study was to determine the metabolizable energy equivalency value of Bacillus subtilis spore and its potential for decreasing feed ME content and cost. One hundred seventy-six day-old male broilers ...

Acids (110%) as research indicates VZ has protease activity and is optimized at lower CP levels. Diets were fed in the mash form from 0-26 d, and VZ was either added post mixing of original feed (D) or sprayed on top of the feed (L). A total of 168 Ross x Ross male broiler chicks were allocated to 24 pens of a battery brooder in a Completely Randomized Design with 12 replicate pens/control and ...

this study was conducted to investigate the effects of different levels of soybean lecithin on performance and blood lipids of broiler chicks. a total of 180 one day old ross 308 broiler chicks were used in a completely randomized design with nine treatments (diets with 0, 0.2, 0.4, 0.6, 0.8, 1, 1.2, 1.4 and 1.6 percent of soybean lecithin) and four replicates for 47 days-rearing period. in ord...

an experiment was conducted to evaluate the feeding value of date pits in broiler chickens. one hundred sixty eight male broiler chicks (ross 308) from 1 to 42 days of age were used. experimental design was crd, in a factorial arrangement of 4 replicates per treatment. the factors included: 3 levels of date pits (10, 20 and 30%) either with or without multi enzyme supplementation. a control die...

background: glutamine supplementation to the pre-starter diet of broiler chicks could improve their performance during the first week of post-hatch. objectives: this experiment was conducted to evaluate the influence of glutamine levels in the pre-starter diet on intestinal mucosa morphology and performance of broiler chicks. method: a total of 160 ross 308, one-day old broilers were used in a ...
