The influence of various factors on the fertility of multiparous kyrgyz sheep

The fertility of multiparous Kyrgyz sheep was studied in this work. It was revealed that the values of young stock actual accretion per 100 lambed ewes might vary greatly with age. Its value was increasing gradually up to the 4-year-old age of ewes. It was found that with the increase in ewes‘ live weight to a certain limit, fertility also increased, and the further increase in live weight was associated with the increase in fertility. Ewes with the live weight of 50.0-54.9 kg had the highest fertility (170.4%). Ewes‘ fertility in relation to age was in the range of 146.0-168.0%. The highest fertility was observed at the age of 4 years (168.0%). Revenues from sales of sheep products were 12,628 som from hybrid animals, including 7,284 som from meat (mutton), 334 som from sheep pelt, and 5,010 som from animal yield. The total receipts from local hair sheep amounted to 10,194 som, including 6,900 som from meat, 54 som from sheep pelt, and 3,240 som from animal yield or, in comparison with hybrid animals, 2,434 (19.3%) som less. © 2018, Pharmainfo Publications.
