DYNAMICS OF DAIRY PRODUCTIVITY OF MARES OF NOVOОLEKSANDROVSKY HEAVY BREED BY SEASON PRODUCTION OF MILK
The article hightlights the dynamics of milk productivity of Novoоleksandrovsky heavy breed mares for 2015-2017 with seasonal milking. During the period of the experiments, the milk productivity of mares increases every year from May to June (F (1.83) = 9.64 p  0.05). Since August, there has been a significant decrease in milk productivity (F (1.88) = 11.71 p  0,05, for lactation number - F (2,42) = 0,35 p> 0,05. The trend of distribution of dairy productivity by months remained similar. The correlation of the milk yield and the mean monthly temperature was 0.29 (F (1.43) = 3.84 p <0.05.
