Ewe with four notes

Early ewes can increase production efficiency and shorten the interval between generations, and the ewes with early mating have stronger motherhood. At present, in some countries, the initial mating age of ewes is 6 to 9 months old, so that the ewes can breed lambs from 11 to 14 months of age. In China, small-tailed sheep can be mated at 6 to 7 months of age, that is, lambs born in spring can participate in breeding.

However, early ewe should pay attention to the following situations:

One should pay attention to the size and condition of the ewes when they are bred. It is generally believed that ewes can be bred when they reach 65% of their mature weight. Therefore, the feeding and management of the ewes before their initial allocation is particularly important.

Second, pay attention to varieties. When the early maturing cultivars were 6 to 7 months old, their physique and body condition met the requirements for normal reproduction, while the late maturing cultivars were not ideal.

Third, pay attention to the mother's birth time and breeding season. Studies have shown that females born in February have high fertility rates from September to October.

Fourth, pay attention to breeding groups. The mating of female lambs and adult ewes in the same group will reduce the breeding rate of female lambs. Therefore, female lambs and adult ewes should be grouped and grouped. In addition, the use of communal lambs of the same age can increase the reproductive rate of female lambs.
