To study the effects of α-galactosidase (α-Gal) supplementation on performance and energy metabolism, 216 Arbor Acres male broilers were placed in 36 cages of 6 birds each and allotted to 4 diets for 42 d, with 0-21 d as starter period and 22-42 d as grower period. The 4 diets were based on corn non-dehulled soybean meal in a 2×2 factorial arrangement, with 2 levels of α-Gal (0 vs. 60 U/kg feed...

Three experiments were conducted to determine the digestible lysine requirement of female turkey poults during the starter period. Birds were fed a standard corn-soybean meal diet until the onset of each trial and were then randomly assigned to treatments that were fed for 2 wk. Dietary treatments included titrated levels of digestible lysine (1.18 to 1.72%) added to a basal corn-soybean meal d...

For chickens, arginine considered an essential amino acid due to the lack of urea cycle in birds. Arginine deficiency causes growth retardation, higher prevalence of disease due to the malfunction of immune system, and lower gastrointestinal capacity. However, higher levels of arginine in the diet improved growth performance, muscle hypertrophy, and meat quality. Arginine reduces carcass fat ac...

Three experiments were conducted to determine the effects of excess arginine on performance, plasma amino acid levels and N balance of young pigs (initial weights 6.9, 7.0 and 10.3 kg, respectively). In a 28-d growth trial, various amounts of arginine (0 to 1.6%) were added to a conventional starter diet. Addition of arginine decreased (P less than .01) average daily feed intake (ADFI) and gain...

an experiment was conducted in order to assess the effects of different levels of dietary canola meal (cm; 0, 10 and 20 %) and copper (0, 125 and 250 mg/kg) on performance, susceptibility to ascites syndrome and some blood metabolites of broiler chickens. during a six week period of experiment, a total of 495 male broilers (ross 308) were used in completely randomized design with a 3×3 factoria...

Three consecutive nitrogen balance experiments with fast-growing male broiler chickens (ROSS 308), both during starter and grower periods, were conducted to determine the ideal ratios of several indispensable amino acids relative to lysine. The control diets based on corn, wheat, fishmeal, field peas, wheat gluten and soybean oil were formulated by computer optimizing to meet the assumed ideal ...

The objectives of this experiment was to evaluate the subsequent growth and organ weights, blood profiles and cecal microbiota of broiler chicks fed pre-starter diets containing fermented soybean meal products during early phase. A total of nine hundred 1-d-old chicks were randomly assigned into six groups with six replicates of 25 chicks each. The chicks were fed control pre-starter diet with ...

To evaluate the effect of adding calcium salt of soybean oil on the performance and growth of suckling calves, 18 Holstein calves, after the birth with weight average 3.94 ± 42.43 kg were randomized into three groups. The experimental allotments including: 1) the starter without calcium salt of soybean oil (control), 2) starter with 0.3% calcium salt of soybean oil and 3) starter containing 0.5...
