an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...

Broilers with lower hatching weight (HW) present poorer performance than those with high HW, but there is limited research on the growth regulation of broilers with lower HW. The objective of this study was to investigate the effect of dietary methionine (Met) levels on the growth performance and breast muscle yield of broilers with different HW and underlying mechanisms. A total of 192 one-day...

Seven duplicate floor pens with 25 day-old commercial chicks were fed a practical type of broiler diet based on maize-palm kernel meal supplemented with varying levels ofniacin so that the rations had 15.0, 22.5, 30.0, 37.5, 45.0, 52.5 and 60.0mg of niacin per kg offeed. The treatments were maintained for a period of 42 days. The results based on liveweight gain, feed intake, apparent utilisati...

The aim of this study was to determine the binding capacity of a hydrated sodium calcium aluminosilicate (HSCAS) for aflatoxin B(1) (AFB(1)), and the efficacy of the HSCAS to reduce the concentrations of residual AFB(1) and its metabolites in the liver and kidney of broilers fed AFB(1). One hundred 1-d-old male broilers (Ross 708) were maintained in chick batteries and allowed ad libitum access...

this experiment was conducted to investigate the effects of different levels of creatine and protein in diets on performance and meat quality of broiler chickens. a total of 320 day old ross broiler chicks were used in a 2×4 factorial arrangement of dietary treatments comprised two levels of protein (ross recommendation and 10% higher than recommendation) and four levels of creatine (0, 0.1, 0....

an experiment was conducted to investigate the effect of thyroid gland activity modulation (hyper or hypothyroidism) on energy utilization in broiler chickens. two hundred and forty one-day-old cobb broiler chicks were distributed into three dietary metabolizable energy (me) treatment groups (80 chicks each). the control group (e0) was fed basal diet (3150 kcal/kg diet), the second group (e1) w...

Aim: To evaluate the effects of inclusion of roasted guar meal, also known as guar korma, as a partial replacement for deoiled soybean meal (SBM) in commercial broiler diets, on production performance and carcass traits of Cobb-400 broiler chickens. Materials and Methods: 1600 one-day-old Cobb-400 broiler chicks were randomly assigned into four dietary treatments, each with four replicates (n =...

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

A study was conducted on the impact of aflatoxin (AF) and mycotoxin binders on immunization against Infectious Bursal Disease (IBD) and Infectious Bronchitis (IB) in chickens. Broiler chicks (7-day-old) were randomly assigned to 9 dietary treatments with 4 replicates of 12 chicks each. Treatments were 1) control; 2) diet containing corn naturally contaminated with AF (NCD); 3) NCD + 0.2% Farmag...
