In unattached housing, the influence of the age of the cow on daily life expectancy was 1.5%, the fat content in milk – 0.6%, the protein content – 1.2%, the number of somatic cells in milk – 1.2%, and for the force of influence was smaller and probably affected only the daily life expectancy and the content of somatic cells in milk. Regardless of the husbandry technology, the percentage of cases of diagnosis of mastitis in cows increases, but the number of cases of mastitis was lower with tethered husbandry. The influence of the month of a cow's lactation on the daily life expectancy for unattached housing was 10%, for the fat content in milk - 1.4%, for the protein content - 10.7%, and for tethered housing - 26.9%, 5, 2% and 16.1%, respectively (Р<0.001). The tendency to increase the incidence of mastitis in the second and third stages of lactation is due to the increase in the age of the animals. When cows are tied, the influence of this factor was 4.6%, 10.4%, and 5.8%, respectively, and when cows are not tied, the degree of influence is lower - 1.02%, 4.15%, and 2. 30%. Mathematical models of the influence of the total nutrition of the ration, the content of raw and non-digested protein in the rumen, the average daily temperature and air humidity of the environment on the daily yield of milk in terms of basic fat content have been developed. Mathematical models have been developed for forecasting daily milk yield and milk quality indicators depending on paratypic factors. The established relationships and features of the influence of the technology of keeping and feeding dairy cattle indicate greater energy efficiency of the untethered technology of keeping cows and young animals fed with full-rational feed mixtures. In experimental farms, insufficient attention is paid to balancing feeding rations, especially for young animals, which   Product Description popup.authors ADMIN Oleksandr Ye.
