Rearing young farm animals in the early stages of postnatal ontogeny is a critical point. There are many aspects of theoretical and practical research on improving the safety and prevention of diseases of calves, but one of the main ones is a comprehensive knowledge of the morphofunctional and adaptive features of calves during the newborn period. To continue to exist in a modified environment is to maintain vital activity and some aspects of homeostasis that are characteristic of organisms of this species, this level of development of its nervous and hormonal mechanisms. When analyzing the incidence and death of calves, it was found that the transfer of calves from individual cells to General ones and the change of milk feeding to hay and mixed feed provokes the growth of diseases at the age of 10 days and older than one month (70%), and also dies at this age (58%). Morpho-physiological features of newborns are the impenetrability of the placenta of hoofed productive animals to the immunoglobulins of the mothers ’ blood. Nature has created a unique mechanism for receiving immunoglobulins in the body of newborn ungulates. After direct maternal immune protection during pregnancy ceases, nature replaces it with colostrum immune protection. To confirm and derive biological laws, the dynamics of immunoglobulins in the blood and colostrum of cows and pigs before and after childbirth were studied.
