The objective of the current study was to evaluate the effect of feeding time restriction in alternate day on performance and Heterophil to Lymphocyte (H/L) ratios as indices stress of broiler chickens. A total 180 seven day-old unsexed broiler chicks were randomly allocated to three treatments: chicks fed ad libitum (P-0); chicks had free access to feed from 07:00 to 09:00, 12:00 to 13:00 and ...

A 21to 42-day feeding study was conducted in Ross male broilers to evaluate the use of dried bakery product (DBP) and the influence of adding fat at different points in the manufacturing process. Six dietary treatments were formulated using a factorial arrangement (3×2 design) with three levels of fat in the mixer (high: 4.8%, medium: 3.8% and low: 2.8%) with or without DBP (0 and 7%). Addition...

the objective of this study was to investigate the effects of different levels of amino acid and feeding methods on performance and immune system of broiler chickens. experimental design was based on completely randomized design in a factorial arrangement with 3 feeding methods [control (ad libitum feed intake), intermittent feeding (if) and continuous feed withdrawal (fw)), and 2 amino acid le...

An Iowa grain processor attempted to alter the typical 12-h preharvest fasting period by giving broilers cornstarch derivative pellets and water for 6 h followed by 6 h of no feed or water. After slaughter, plant food inspectors determined that livers from the treatment group were lighter in color than normal, and consequently a significant number of chicken carcasses were condemned for human c...

The present study was carried out to evaluate the effects of thymol and carvacrol supplementation on performance, immune response, antioxidant enzyme activity and blood parameters of heat stressed broilers. Broilers were fed with commercial diet till 25 d of age, then they were allocated to a completely randomized design with a 3 × 2 factorial arrangement with 6 treatments including 3 levels of...

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...

Two experiments with 14- to 35-d-old male broilers were performed to investigate the interactions between increasing levels of balanced protein (BP; 9.7, 10.7, 11.7, and 12.7 g of digestible Lys/kg of feed) and physical feed form. In Experiment 1 diets were offered as coarse mash and pellets of either good or poor quality. Good pellet quality was characterized by high durability. In Experiment ...

for determination the effect of lemon pulp levels and organic acid premix (globacid) on performance, carcass traits,immune system, biochemical parameters and intestinal morphology of broilers, 288 ross broilers were used in 3×2 factorial arrangement with three levels of lemon pulp (0, 1.5 and 3 percent) and two levels of globacid (0 and 0.1 percent) in a completely randomized design with six tr...
