Analytical control of protein and amino acid (AA) contents of animal tissues is an important problem in the fundamental and applied aspects. The aims of the work were the following: to measure the pig blood AAs; and to establish the correlations between AAs and biochemical parameters in dependence on the pig fattening duration. All 80 animals were divided onto 4 animal groups: 65, 72, 82, and 90 fattening days. The correlations between AAs and the total protein or its fractions (TP&F), nitrogen metabolites, carbohydrates, lipids, some enzymes in the pig blood for each of these animal groups obtained for the first time. The authors established the following total amounts of correlation coefficients (with reasonable p-values) in each of the group separately: group 1, 1* (p < 0.05); group 2, 0; group 3, 28* (p < 0.05) and 9** (p < 0.01); group 4, 28* (p < 0.05) and 25** (p < 0.01). Thus, about 82−90 days (groups 3 and 4) can be the optimal for the pig fattening, based on the correlation analysis for the numerous data of major AA and biochemical parameters of pig blood. These results can be useful for animal health monitoring and husbandry.
分析动物组织中蛋白质和氨基酸（AA）含量的控制是基础和应用方面的重要问题。本工作的目的如下：测量猪血液中的 AA；并建立 AA 与生化参数之间的相关性，以依赖于猪的育肥时间。所有 80 只动物被分为 4 个动物组：65、72、82 和 90 天育肥期。首次获得了这些动物组中每个组中 AA 与总蛋白或其分数（TP&F）、氮代谢物、碳水化合物、脂质和猪血液中某些酶之间的相关性。作者分别在每个组中确定了以下总相关系数（具有合理的 p 值）的数量：第 1 组，1*（p < 0.05）；第 2 组，0；第 3 组，28*（p < 0.05）和 9**（p < 0.01）；第 4 组，28*（p < 0.05）和 25**（p < 0.01）。因此，基于对大量猪血液主要 AA 和生化参数数据的相关性分析，约 82-90 天（第 3 组和第 4 组）可以是猪育肥的最佳时间。这些结果可用于动物健康监测和饲养。
