Five strokes to improve ewes' fertility

Scientific arrangements for lambing

The ewes' ectopic period is generally between 75 and 90 days of age, and the initial age can be as early as 5 to 7 months and weighing 15 to 20 kilograms. Two-year-olds are arranged for breeding in spring and autumn; two-year triplets are usually every 8 months for a breeding cycle, in which the gestation period is 5 months, the lactation period is 2 months, and the breeding period is 1 month. For the estrus ewes to be timely mated, a 2 to 6 year old ram can afford 20 to 30 breeding ewes during natural mating, and the ratio of male to female is 1:40 when artificially assisted in mating. Two or three-year-old children a year, the number of litters per year is between 2 and 4.

Implement early weaning of lambs

Lambs are mostly weaned at two months of age. The colostrum should be fed to the newborn lambs. The lambs should be fed scientifically from 15 to 20 days of age. Every day, 30 to 50 grams of mixed concentrates should be supplemented, and 70 to 100 grams of mixed concentrates should be supplemented at 30 days. ~ 150 grams, after 50 days of age to feed green rough feed, appropriate supplements fed mixed concentrate. Careful feeding, lambs can be weaned 10 to 15 days earlier.
Shortening ewes during gestation

Ewes are usually about 150 days pregnant. Using estradiol benzoate or cloprostenol injection 1 to 2 milliliters 3 days before the pre-production can make 90% of the ewe lambs within 48 hours. .

Strengthen feeding management

In the summer and autumn seasons, green fodder such as fresh grass and leaves is mainly used, and it is appropriate to mix with corn, bran and other concentrates; winter and spring seasons are mainly fed with ammoniated feed. Feeding should be quantified regularly, requiring that the feed be clean and fresh, free from silt and mildew. Provide sufficient drinking water, winter to drink warm water 30 °C ~ 40 °C is appropriate. Allow the ewe to exercise properly and keep the environment quiet. It is forbidden to chase, whip, and kick the pregnant ewes.

Strengthening health and epidemic prevention

Intensive sweeping homes, regular use of levamisole to drive off parasites in vivo and in vitro; regular injection of various vaccines; ground observation of the sheep, once the diseased sheep, immediately isolated diagnosis and treatment, strict disinfection.
