An experiment was carried out to determine the effects of different levels of lysine and protein on the performance of 240 Hy-Line W36 layers. Ten experimental diets were tested in a 2×5 factorial arrangement with a completely randomized design. Two basal diets (13 and 14% protein) were tested at different levels (10 and 20% lower than NRC, NRC and 10 and 20% above NRC recommendations). Dietary...

This experiment was conducted to compare the effects of Roxarsone (Rox) and Bacitracin methylen disalicylat (BMD) on the performance of broiler chicks. A control corn-soybean meal diet without growth promoter was formulated according to NRC (1994) recommendation for starter (0-21d) and grower (22-42d) periods. The control diet was also supplemented with Rox (50 mg/kg diet ) BMD (55 mg/kg diet) ...

In a 2×2 factorial experiment the hypotheses tested were that the metabolic acid load caused by benzoic acid (BA) added to the feed affects bone mineralization of weanling pigs, and that a wide dietary calcium (Ca) to phosphorus (P) ratio in phytase-supplemented feeds with a marginal P concentration has a positive effect on bone mineralization. The four experimental diets, which contained 0.4% ...

The effect of dietary protein level and feed restriction on performance, body temperature and hematological values was evaluated, using Ross 308 broiler chicks under heat stress. For this purpose, three dietary treatments were fed to broilers during 21 to 42 days of age. Two treatments consisted of diets with protein levels recommended by NRC, 1994 and 85% of NRC recommendation and were fed ad-...

The aim of this study was to evaluate the effect of inclusion of tannic acid on some performance traits and nutrient digestibility in Holstein dairy calves. A total of 20 seven days old Holstein calves were randomly assigned to 4 experimental treatments with 5 calves each. The treatments were as follows: 1) basal diet formulated to meet all nutritional requirement of calves according to NRC (20...

In this research, influence of Revabio enzyme on improving anti-nutritional of wheat bran (high in fiber, non-starch polysaccharides and phytate) were investigated. The total number of 320 commercial male broiler chicks (Ross 308) in a factorial experiment 4×2 with four replications were used. Treatment consists of four levels of wheat bran (0, 10, 15 and 20 percent) and two levels of enzyme (0...

Three-hundred and twenty 7-day-old Ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin B 1 (AFB1) from 7 to 28 days of age. Sodium bentonite (0.5%), yeast (Saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (HSCAS) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...
