INFLUENCE OF FEEDING AND LIVESTOCK MANAGEMENT ON DEVELOPMENT OF HOLSTEIN CATTLE GENETIC POTENTIAL

abstract 1051501017 issue 105 pp. 325 – 338 30.01.2015 ru 943
This research reviews an analysis of several problems of milk production process as well as fast methods of dairy cows' health control widely used in the countries of high-level dairy breeding. The results of milk analysis via test stripes reveal that about 30% of cows during transition period - phases transit 2 and 1st phase of lactation - have clinical and subclinical ketosis marks what comes as one of the reasons of cow's low productivity. Evaluation of cows' fatness evidence that only 46,4% of tested animals have normal fatness according to the appropriate lactation period, whereas other animals have too high fatness index and only very small part - 1% have extremely low fatness index. Cows' obesity leads in future to ketosis and disturbance in metabolism. The research also revealed nonconformities in boxes size, they do not satisfy requirements of comfortable Holstein cows handling. The article provides recommendations on implementation of tested methods based on survey in order to suggest the ways of milk production efficiency increase
