Abstract

High productivity breed cows are delivered to the Republic recently for intensive development of livestock. Subsidies are allocated to farmers, modern type livestock complexes are constructed by state. But, although all conducted works, there are several diseases which prevent the development of livestock. The leading one of such diseases are diseases occurred after delivery among breed cows. Along with various factors, special attention involves the age of animals and number of lactation in occurrence of such diseases. In order to study the effect of livestock age and the number of lactations on the occurrence of diseases, a study was conducted on highly productive thoroughbred and local cows of the Guba-Khachmaz region. During the study period, on the farms located in the Guba, Gusar, Khachmaz regions of the Guba-Khachmaz economic region, 4826 cattle were examined. Thus, in the Guba region, 828 heads of cows were examined: 130 heads at the Shahin farm, 141 heads at the Guneshli farm, 438 heads at the Pirvahid farm, and 119 heads at private farms. In the Gusar region, a total of 3696 cattle were examined: 3540 animals in the Shahdag livestock complex, 119 cows on private farms. In the Khachmaz region, 302 heads of cattle were examined: on the Isaev farm – 170 heads, on private farms - 132 heads of cows. Metritis was observed in 361cows from 4826 cows between 3–8 ages and older, as well as passing lactation for 6 and more times (7.5%), mastitis in 278 of 4826 cows (5.8%), latency delay in 106 of 4826 cows (2.2%), and birth paresis in 42 of 4826 cows (0.9%) in Guba – Khachmaz natural – economic geographic region. The results of the study show that as the age of cows and the number of lactations increase, their sensitivity to postpartum diseases increases.
