Assessment 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 کاملDigestible 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 کاملValine nutrient recommendations for Ross x Ross 308 broilers.
Studies delineating the dietary Val needs of modern commercial broilers are sparse. Three studies were conducted to determine the dietary Val nutrient needs of Ross x Ross 308 male broilers. Three time periods were evaluated independently, 0 to 14 d (starter), 14 to 28 d (grower), and 28 to 42 d (finisher) of age. Corn- and peanut meal-based diets for each feeding phase served to titrate the Va...
متن کاملEffect of dietary lysine on hepatic lysine catabolism in broilers.
Lysine is frequently a first- or second-limiting amino acid in poultry diets. Improving the efficiency of lysine use for protein synthesis would effectively lower the lysine requirement and decrease feed costs. Understanding how lysine is degraded and how the degradation is regulated would identify potential molecular targets for interventions to decrease lysine degradation. To better understan...
متن کاملRegulation of Lysine and Threonine Synthesis.
Human and monogastric animals cannot synthesize 10 out of the 20 amino acids and therefore need to obtain these from their diet. Among the essential amino acids, lysine and threonine are considered to be exceedingly important in that they are the most limiting essential amino acids in cereal grains, which represent the largest source of food worldwide (Bright and Shewry, 1983). Because of the n...
