This study determined the effect of feeding trough shapes on growth performance, carcass characteristics and cost benefit analysis 180 broiler chickens two strains (90 birds each Marshal Hubbard strains) subjected to circular, rectangular square-shaped 2 troughs with a surface area 900 cm each. The chicks were brooded for weeks thereafter allotted into six treatment groups 30 each, consisting 3...

OBJECTIVE The net energy requirement for the maintenance (NEm) of broilers was determined using regression models by the indirect calorimetry method (ICM) or the comparative slaughter method (CSM). METHODS A 2×4 factorial arrangement of treatments including the evaluation method (ICM or CSM) and feed intake (25%, 50%, 75%, or 100% of ad libitum recommended) was employed in this experiment. In...

The study was conducted to determine the effects on growth performance and immune response of free-range chicken supplemented with different levels spirulina in their diet. Sixty free range chicken, fifteen day-olds, were used which randomly distributed four treatments, three replicates each treatment five experimental birds replicate. Treatment 1- Control (pure commercial feeds); 2- 4% feeds; ...

Ninety six 21 day- old unsexed broiler chickens were used for the study designed to evaluate effect of different levels pawpaw leaf meal on serum biochemistry chickens. The experiment consisted four treatment groups, each in three replicates eight birds per replicate. treatments reflect inclusion meal: T1 (control 0 g/kg PLM feed), T2 (3 T3 (5 feed) and T4 (7 feed). was framed a completely rand...

effect of adding hibiscus sabdariffa (hs) in diet on performance and immune response of broilers was examined during aflatoxicosis using a total of 192 day-old ross 308 male chicks in a completely randomized design with four treatments, four replicates and 12 chicks per each replicate. treatments were include: 1. negative control (without additives), 2. positive control (2.5 mg aflatoxin b1/kg)...

in this research the effect of feeding wheat/ barley based diets supplemented with three commercial enzymes containing xylanase and ?-glucanase activities and including matrix value their on performance and gastrointestinal tract size of broiler chicks was investigated. a total of 260-day-old male broiler chicks (ross 308) were allocated to 5 treatment groups, with 4 replicates per treatment an...

the study was carried out to evaluate the effects of complete replacement of maize with two varieties of guinea corn and two varieties of millets on the growth performance and nutrient retention in broiler chickens. five isonitrogenous and isocaloric diets for the broiler starter (23.5% cp; 2800 kcal/me) and finisher (21.5% cp; 2900 kcal/me) phases were formulated. diet 1 consisted on a maize b...

An experiment was conducted to study the effect of supplementing Non-starch Polysaccharide enzymes and prebiotics alone or in combination to sub-optimal energy corn soybeanbased broiler diets on performance. 150 day old broiler chicks were randomly distributed in to five experimental groups, six replicates per group and five birds per replicate. A standard diet (SD) and a basal diet (BD) (225 k...

this study was designed to investigate the effects of different levels of tarragon powder on performance, carcass characteristics of broiler chickens. two hundred ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. at each replicate ten birds were used. experimental diets were set on the basis of corn-soy-wheat and ross 308 broiler chic...

In this experiment 144 Hy-line (W36) laying hens, 65 to 77 weeks of age were separated into 4 treatments with 3 replicates (12 birds per replicate) in a completely randomized design experiment. The grass clipping wastes incorporated into a complete formulated layer diet, consisting on a corn and soybean based diet, were 0, 1.5, 3.0 and 4.5% in 1 to 4 experimental groups. The results showed that...
