Digestible lysine requirements of male and female broilers from fourteen to twenty-eight days of age.
There is little research data available on the digestible Lys requirement of broilers from 2 to 4 wk of age. Two experiments were conducted to determine the digestible Lys requirements of male and female Ross x Ross TP16 broilers from 14 to 28 d. Two diets (dilution and summit) consisting of corn, soybean meal, poultry by-product meal, and peanut meal were formulated to be adequate in all other...
متن کاملDigestible lysine requirements of male broilers from 1 to 42 days of age reassessed
Three experiments were conducted separately to estimate the digestible Lys (dig. Lys) requirements of Cobb × Cobb 500 male broilers using different statistical models. For each experiment, 1,200 chicks were housed in 48 floor pens in a completely randomized design with 6 treatments and 8 replicates. Broilers were fed diets with increasing dig. Lys levels from 1 to 12 d (Exp. 1), from 12 to 28 d...
متن کاملAssessment of Threonine-to-Lysine Ratio of Male Broilers From 35 to 49 Days of Age
Digestible lysine (dLys) and digestible threonine (dThr) are considered to be the second and third limiting amino acids (AA) after sulfur containing amino acids (dTSAA) for broilers fed corn-soybean meal-based diets. Diets formulated to meet the AA requirements of modern broiler strains are required to maximize performance. Currently, nutritionists formulate poultry diets using the ideal protei...
متن کاملDietary digestible lysine requirements of male and female broilers from forty-nine to sixty-three days of age.
Experiments were conducted to evaluate digestible (dig) Lys requirements of male and female broiler chickens from 49 to 63 d of age. A dose-response diet consisting of corn, soybean meal, and corn gluten meal was formulated to be adequate in dig amino acid concentrations with the exception of Lys. L-Lysine . HCl was added to the dose-response diet to create 7 experimental diets. Concentrations ...
متن کاملThe Optimal Ratio of Apparent Digestible Valine to Lysine to Maximize Growth Performance of the Nursery Pig
A total of 210 nursery pigs (initially 19.6 lb and approximately 28 d of age) were used in a 21-d growth assay to determine the optimal ratio of valine to lysine to maximize growth performance. The seven treatments consisted of a basal diet (14.2% CP; 1.07% apparent digestible lysine) with increasing ratios of valine:lysine (48, 53, 58, 63, 69, and 74%) and a negative control containing 0.97% l...
