Answer: 1 Select the Damo lamb and male ewes to keep seeding. Twin lambs or multiple lambs are hereditary and were selected from the reserved herds of male and female rams when they were selected as reserved male and female ewes. These male and female mutton with good genetic basis are reserved for species use, which can fully exert their genetic potential in breeding and increase the chance of ewes having multiple births.
2 adequate nutrition. The better the ewe's emu, the greater the lamb's weight, the higher the odds.
3 Implement two breedings. When the ewes are in estrus, the practice of double breeding or two breeding insemination can increase the probability of producing twin lambs. Using the two breeding methods can maintain the fertilized spermatozoa in the genital tract and increase the chance of fertilization. Commonly used methods: For the ewes that confirm estrus, insemination is performed once and after 12 hours and 24 hours. Generally, the insemination interval is 10 to 12 hours.
