This study was carried out to investigate the effect of humic acids (HA) supplementation provided through drinking water on performance, carcass and some gut traits of broilers. In a randomized design, 480 mixed-sexes Ross 308 broilers were allocated into four experimental groups consisted of four replicate (30 birds per replication). All birds were housed in pens over 42 day. All chickens were...

Commercial broiler males were used to evaluate body temperature response to heat stress and its relationship to gain, feed consumption, and feed conversion ratio. Individual gain, feed consumption, and feed conversion ratio were obtained from 28 to 49 d in a heat stress environment (32 C) and compared to a 21 C environment. Body temperatures were measured at 28, 35, and 42 d, then daily from 43...

The effect of either hot or cool brooding litter temperature on feed consumption, BW, and mortality of broiler chicks that had been exposed to either normal or high temperature during latter stages of incubation was studied in 2 experiments. The duration of experiments 1 and 2 was 14 and 21 d, respectively, with BW and feed consumption determined at 2, 5, 7, and 14 d of age in experiment 1 and ...

A comparative study was performed to investigate the efficacy of KiFAY as a feed additive on performance parameters, thyroid, and pancreatic hormone levels in broilers. Ninety birds (Vencobb 400) were randomly divided into three groups viz., Control (no DL-methionine supplementation), Treatment1 (containing added DL-methionine) and Treatment 2 (containing KiFAY and without DL-methionine supplem...

Contamination of animal and poultry feeds by Fusarium and the mycotoxin Fumonisin B1 is frequent in the feed supply chain. The present study evaluated the prevalence of fumonisin B1 producing Fusarium among irradiated and non-irradiated animal and poultry feed mixtures. Further, the efficiency of γ-rays (2.5, 5.0, 7.5, and 10.0 kGy) to minimize Fusarium growth and biosynthesis of fumonisin B1 i...

An experiment was conducted from 18th October, 2006 to 18th January, 2007 at IAAS Livestock Farm, Rampur, Chitwan to determine the substitution effects of soybean meal with brewer’s dried grain (BDG) on the performance, economics and meat traits of swine production. Starter, grower and finisher diets were formulated containing 18, 16, and 14% CP respectively with 3000 Kcal/kg ME and adequately ...

The present study aimed to investigate the effects of dietary supplementation of multi-enzyme on productive performance of laying hens fed different levels of safflower meal. A total of 250 Leghorn laying hens (Hy-Line W-36) 47 weeks-old were randomly assigned into 10 experimental treatments with 5 replicates of 5 birds each. Experimental treatments consisted of five safflower meal levels (0.0,...

For 1,442 Belgian Blue bulls performance-tested at the Centre de Sélection de la Race Blanc-Bleue Belge, nine traits were observed: height at withers at 7 mo, height at withers at 13 mo, weight at 7 mo, weight at 13 mo, average feed consumption of concentrates, average daily gain, average feed consumption of concentrates per average daily gain, average feed consumption of concentrates per mean ...

an experiment was conducted to evaluate the effect of dietary crude protein and lysine levels on quality and quantity of egg production. fifteen diets consisted of 3 levels of protein (14, 15 and 16%) and 5 levels of lysine (0.71, 0.74, 0.77, 0.80 and 0.83 %) in a 35 factorial arrangement were provided. each diet was randomly fed to 4 replicates of 12 birds, during four periods of 4 weeks (28-...
