Raising New Technology for Cows and Mothers
1. Xinjiang Animal Husbandry Academy cooperated with Cornell University in the United States to use sperm separation technology to produce in vitro sex-control embryos for dairy cows. The application of this technology will enable the cows to have only mother-fitters as they wish, which has special effects on improving the rapid reproduction of high-yielding dairy cows.
2, feeding mother spirit. Feeding Mother Spirit (developed by Hunan Agricultural University), once a day, 3 to 5 grams each time, 10 days before breeding, 10 days straight to 10 days after mixing, and fed with spices or hydrating Beverages, the rate of females is 84.4. %.
3, light stimulation of maternal mother. When cows are mated or inseminated, the cows are allowed to stand for 20 to 30 minutes toward the sun, preferably from 10:30 to 12:30 in the morning on a sunny day, and the rate of female production is 83.7%.
4. 20 to 30 minutes before breeding or insemination, 20% of 20% white sugar water is input into the cow's uterus, or about 5 ml of 5% arginine is used, and the rate of maternal birth is 85% or more.
5. Neutral vitamin B12 injection is used as a freeze-dried diluent to increase sperm motility, fertilization rate, and female licking rate.
6. Give the cows more green and juicy feed to increase the body's vitamins and carotene. It can keep the uterus and ovarian steroids synthesis cells of cows from the harm of oxidants, maintain ovulation and implantation, and also help the sperm chromosome to give priority to the same egg. Combine.
7. The cows enter the thawed semen 8 hours before ovulation, and the rate of mother cubs produced is 86.67%.
