Heavy metals can selectively accumulate in certain organs and remain in them for a long time. As a result, the accumulation of metal in one or another organ may cause strongest intoxication of the animal. The purpose of the research is to study the morphological and biochemical composition of the blood of young cattle of different breeds of the dairy and dairy-and-beef direction of productivity fed in the technogenic zone in the RNO-Alania diets with a high content of heavy metals. According to the principle of analogues, taking into account the breed, origin, age, sex and body weight, 4 groups of 10 animals each of different breed were formed: Group I - black and white, Group II - Danish Red, Group III - Swiss, and Group IV - Simmental. The experimental material was statistically processed using the Microsoft Excel software for mathematical analysis. With a tendency of unreliable differences in morphological indices of blood, in diminishing numbers of erythrocytes and hemoglobin, the test breeds should be arranged in the following order: Simmental, Swiss, Red Danish, Black and White. At the same time, as compared to the animals of the black-and-white breed, the young cattle of the Simmental breed showed the best level of intermediate metabolism, which resulted in an increase in total protein and sugar in the blood, which indicates an improvement in their protein and energy metabolism; an increase in the content of albumin in the liquid internal medium and γ-globulins; an increase in concentration of total lipids in serum, respectively, while reducing the level of cholesterol, which indicates an improvement fat metabolism in animals; a significant decrease in blood saturation with cadmium, lead and zinc, respectively, by 26.8, 48.8 and 30.6%. The highest content of these elements was noted in the wool, then in decreasing order: in bone tissue, liver, muscle tissue, lungs, kidneys. Moreover, between the level of heavy metals in muscles, liver and lungs, on the one hand, and in the wool, bone tissue and kidneys, on the other hand, there was an inversely proportional relationship.

考虑到品种特征，重金属对幼牛血液形态和生化组成的影响

重金属可以选择性地堆积在某些器官中，并在其中保留很长时间。结果，金属在一个或另一个器官中的积累可能导致最强烈的动物中毒。该研究的目的是研究在RNO-Alania日粮中技术含量较高的RNO-Alania日粮中不同品种的奶牛的奶的形态和生化组成以及奶牛生产的方向。重金属。根据类似物的原理，考虑到品种，起源，年龄，性别和体重，共分为4组，每组10个动物，每个品种均不同：第一组-黑色和白色，第二组-丹麦红，第三组-瑞士人，第IV组-西门塔尔。使用Microsoft Excel软件对实验材料进行统计处理，以进行数学分析。由于血液形态学指标的差异存在不可靠的趋势，随着红细胞和血红蛋白数量的减少，应按以下顺序排列测试品种：西门塔尔，瑞士，丹麦红，黑和白。同时，与黑白品种的动物相比，西门塔尔品种的幼牛表现出最佳的中间代谢水平，这导致血液中总蛋白质和糖分增加，这表明他们的蛋白质和能量代谢得到改善；液体内部介质和γ-球蛋白中白蛋白的含量增加；分别增加血清中总脂质的浓度，同时降低胆固醇水平，表明动物脂肪代谢得到改善；镉，铅和锌的血液饱和度分别显着降低了26.8、48.8和30.6％。这些元素的含量最高的是羊毛，然后以降序排列：骨骼组织，肝脏，肌肉组织，肺，肾脏。而且，一方面，在肌肉，肝脏和肺中的重金属含量之间，另一方面，在羊毛，骨骼组织和肾脏中的重金属含量之间存在反比例关系。
