This experiment was conducted to study the effects of two kinds of sodium and calcium bentonite (NaB and CaB) on performance, blood biochemical parameters, carcass characteristics and tibia ash of broiler chickens. Two hundred and sixty day old broilers of male Ross 308 strain were allocated to 5 treatments with four replicatates and 13 broilers in each. The experiment was carried out in a comp...

Problem Statement: The efficacy of Methionine (Met) sparing effect of Betaine (BET) has been shown to be associated with dietary compositions, animal physiological stage and living conditions. This study was to determine the extent to which dietary Met could be replaced by BET in broiler chickens under the feeding conditions specific to Chinese poultry industry.Approach: A total of 900 day-old ...

Crossbred growing-finishing pigs (112 barrows, 48 gilts) were used to determine the effect of reducing excess dietary arginine, through feedstuff variation, on performance, carcass composition and plasma amino acid concentrations. Diets contained five, four, three or two times the NRC requirement for arginine. Lysine in all diets was formulated to be equal to NRC requirements, and all diets con...

A total of 240 Ross 308 day-old male broiler chicks within a completely randomized design were used in this experiment to evaluate the effects of dietary inclusion of turmeric powder and cinnamon powder on performance and some immune responses of broiler chickens. Dietary treatments were as follow: a corn-soybean meal basal diet (control); basal diet + 10 ppm avilamycin; basal diet + 2.5 g/Kg t...

the objective followed in this study was to determine the amen equivalency of multienzyme natuzyme-p. one hundred and sixty male ross 308 broiler chicks were made use of in the experimentations. graded levels of amen, 2600, 2750, 2900, plus 3050 kcal/kg in the starter, and 2700, 2850, 3000, plus 3150 kcal/kg of the diet in the grower periods were used throughout the study. all the nutrients oth...

An experiment was conducted to determine the effect of different levels of potato replacing maizeseed on performance characteristicsand immunes system of broiler chicken in a completely randomized design. A total of 220 broiler chicks were randomly assigned to 5 treatment groups, with 4 replicates of 11 birds each. The chicks in the first group were fed basal diet (control), 2nd and 3rd groups ...

effect of adding melissa officinalis aqueous extract was studied on immune response and performance in 200 ross 308 broiler chicks in a completely randomized design with five treatments and four replicates and 10 observations per replicate. the amounts of 0 (control), 0.5, 1, 1.5 and 2 ml/l lemon balm extract were added in drinking water for 42 days. humoral immunity was evaluated by injection ...

Two experiments were conducted to investigate the effect of low-CP diets supplemented with crystalline amino acids, according to an ideal amino acid ratio, on the performance, plasma metabolites, nutrient digestibility, nitrogen balance, and water intake in male and female chickens from 1 to 48 d of age using a 4-phase feeding program: prestarter (1-7 d), starter (8-21 d), grower (22-35 d), and...

This study was performed to investigate the effects of dietary threonine (Thr). level on performance, metabolizable energy, intestinal morphology, and immune system in coccidian–infected broiler chickens. The diets contained: 88%, 100% (Non challenged (NC) and challenged control (PC)), 112%, 124%, and 136% of Thr requirement according to Cobb 500 recommendation and fed during grower (pre challe...

The aim of this study was to compare the effects of three antibiotic alternatives with a control (Antibiotic-free) and an antibiotic diet on performance and gut morphology of broilers reared on litter. 600 day-old ROSS-308 chicks were assigned to 48 pens in a CRD design with 6 × 2 factorial arrangements, in which 2 levels of chick density (5 and 7.5 chicks/m2) and 6 experimental diets (control,...
