摘要：The article studies the influence of the frequency and time of consumption of colostrum on the immunobiological reactivity of lambs obtained from mothers of the same age, selected according to the principle of analogues. It has been established that first lambers (9–16 months) with intensive rearing and abundant feeding have an average level of resistance of the organism and its indicators are characterized by stability. The offspring obtained from these first lambers (experimental group) in terms of the level of immune parameters are not inferior to their peers obtained from the ewes of the control group. Lambs from first lambers in terms of lysozyme activity of blood serum, immunoglobulin content are superior to their peers from older ewes (the difference is not statistically significant, P> 0.05). At the same time, young animals regardless of the age of their mothers have the same vitality. The lambs' mortality from birth to wean in the experimental and control groups was approximately the same - 7.2 and 8.0%, respectively.
