Dairy cow embryo transfer technology succeeds in Yongji
In Yongji County, the first example of a full-moon dairy cow produced using the embryo transfer technology of dairy cows was “full moonâ€, which signified the success of dairy embryo transfer technology in this county.
On May 26th, this cow, whose embryo was transplanted by the cattle's abdomen, grew from 44 kg to more than 80 kg in only one month, and was able to produce about 40 kg of fresh milk per day.
Last year, Yongji County actively promoted the technology of embryo transfer of cows while steadily carrying out the work of converting cows to cows. They were strictly inspected in the townships of Xiyang, Bei Dahu, etc. according to the age, condition of the cattle, whether there were diseases in the reproductive tract, and whether there was any regularity in the estrus, and among the 47 recipients of the primary selection, 3 were selected. The bovine embryos were transplanted with only one normal pregnancy.
On July 15, 2005, Xishu hybrid cows from Xushan Wu, Xingyang Village, Xiyang Township were in heat. On July 21st, the expert team went to Xu Shuwu’s home to directly inspect the recipient cows, and selected dairy cattle frozen embryos from the Beijing Dairy Cow Center. Embryo transfer was performed on recipient cattle. On the morning of April 22 this year, the recipient cow successfully produced a female cow with a weight of 44 kilograms.
According to the person in charge of the Xiyang Town Animal Husbandry Station, at present, the black-and-white cows who are using embryos for the transfer of yellow cattle's abdomen are growing normally. The market price can reach 10,000 yuan by the age of one year. Farmers in the vicinity have contacted the county's breeding station through various forms and requested that their cattle be transplanted with embryos from cattle.
