An experiment was conducted to determine the effects of unsaturated fatty acids supplementation on growth performance and carcass characteristics of finishing lambs. Thirty-two finishing Afshari lambs (initial weigh 58 ± 5 kg and 8 mo age) were used in a completely randomized design with 4 treatments (slaughtered in time series) and 8 lambs/treatment for the final 30 d before slaughter. The sla...

recent experiment was performed in order to determine effects of dietary l-threonine supplementation levels in japanese quails’ diets on performance, reproductive and internal organs and feathers growth. one hundred and forty four, 1-d old japanese quails, have been selected and randomly distributed between six treatments and four replicates. basal experimental ration was based on wheat, withou...

this experiment was conducted to determine the effects of myrtle essential oil (meo) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. a total of 200 ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...

introduction under commercial conditions broiler are feed restricted during rearing to limit growth rate. this quantitative restriction of feed intake aims at avoiding rapid growth and high body weights, which are associated with pathological conditions, such as ascites, lameness, and mortality. feed restriction (fr) in breeder layer hens was rarely and fr used for poor reproductive results and...

Two experiments were conducted to identify factors influencing feed conversion in broilers. The first experiment was conducted to develop a test for body temperature (BT) under mild handling stress. In the first experiment, BT was recorded periodically with birds briefly restrained after they had been removed from feed with either continuous lighting or 16L:8D. Body temperature was affected by ...

AIM This study was carried out to evaluate groundnut haulms (GNH) as alternate feed source by its incorporation and assessment in terms of feed intake and growth performance in the diets of broilers. MATERIALS AND METHODS A total of 240 1-day-old Cobb-400 broiler chicks were randomly assigned to four dietary treatments each with three replicates (n=60). Experimental Birds in group T1 were fed...

A feeding trial was carried out to investigate the effects of lecithin on growth performance, nutrient digestibility, lipid profile, carcass characteristics and meat quality of broiler chickens. A total of 240 oneday- old male broiler chicks (Cobb 500) were obtained from a local hatchery and raised for 42 days. The chicks were divided into 5 dietary treatments. The diets supplemented with prill...

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...
