We postulated that the use of optimal levels and proportions of Lys, Arg and Met in compound feed allows for optimal exploitation of the growth potential of contemporary slaughter turkey hybrids and reduces metabolic disorders. The aim of the study was to determine the effect of different proportions of Lys, Arg and Met in diets whose Lys content is in accordance with NRC recommendations, that is a low level, on selected parameters of protein, lipid and carbohydrate metabolism and on hormone secretion in turkeys. The lowest Arg content (90% Lys) in the diet resulted in an increase in plasma total cholesterol levels in the turkeys as compared to higher Arg content (100% or 110% of Lys), (2.50 vs. 2.09 vs. 1.83). Plasma HDL and creatinine concentration increased in turkeys fed diets with higher Arg content (100% and 110% Lys) compared to turkeys receiving the diet with the lowest Arg content (90% Lys). Compared to turkeys receiving the lowest and intermediate Arg content (90% and 100% Lys), the diet with the highest content of this AA (110% Lys) resulted in an increase in the plasma T4 level (71.21 vs. 86.60 vs. 128.2). The varied Arg and Met levels relative to Lys did not affect the secretion of neurotransmitters or hormones regulating glucose metabolism. At low levels of Met in the diet, an decrease in Arg relative to Lys from 100% to 90% caused a growth depression of turkeys (10.68 vs. 10.21 kg), which was not noted in the case of the higher Met content. When using the Lys level recommended by NRC in the turkey diet, the optimal Arg level is 100% and Met is 45% compared to Lys.

赖氨酸、精氨酸和蛋氨酸的不同日粮比例对火鸡生化参数和激素分泌的影响。

我们假设在配合饲料中使用最佳水平和比例的 Lys、Arg 和 Met 可以最佳地利用当代屠宰火鸡杂种的生长潜力并减少代谢紊乱。该研究的目的是确定在赖氨酸含量符合 NRC 建议（即低水平）的日粮中不同比例的赖氨酸、精氨酸和甲硫氨酸对蛋白质、脂质和碳水化合物代谢的选定参数以及激素的影响。火鸡的分泌物。与较高的 Arg 含量（Lys 的 100% 或 110%）相比，饮食中最低 Arg 含量（90% Lys）导致火鸡血浆总胆固醇水平增加（2.50 vs. 2.09 vs. 1.83）。与接受最低 Arg 含量（90% Lys）饮食的火鸡相比，喂养高 Arg 含量（100% 和 110% Lys）饮食的火鸡血浆 HDL 和肌酐浓度增加。与接受最低和中等 Arg 含量（90% 和 100% Lys）的火鸡相比，这种 AA 含量最高（110% Lys）的饮食导致血浆 T4 水平增加（71.21 vs. 86.60 vs. 128.2） ）。相对于赖氨酸的不同 Arg 和 Met 水平不影响调节葡萄糖代谢的神经递质或激素的分泌。在日粮中 Met 水平较低时，Arg 相对于 Lys 的降低从 100% 到 90% 会导致火鸡的生长抑制（10.68 与 10.21 kg），这在 Met 含量较高的情况下没有注意到。当在火鸡饮食中使用 NRC 推荐的赖氨酸水平时，
