Giloyan, G.H. | Kasumyan, N.A.
The data of the study indicate that the service period of the cows of the 4th-5th lactation is 5-58 days higher than the norm in the “Vamaks” LLC cattle farm of the Syunik region of the RA, and the coefficient of reproductive ability varies in the range of 86.3-98.6 %. Due to sterility, the loss of lactations in the 5th lactation is 16 and the loss of milk quantity is 126 tons. We propose to identify and inseminate (mate) animals with sexual desire in a timely manner, as well as to establish strict veterinary control to monitor and regulate the service period of 4-5 calving cows.
