Embodiment

[0034]Yu Sheep Farm selected Gansu Alpine Merino Fine Wool Sheep from Chifeng Grassland Jinfeng Animal Husbandry Co., Ltd., Inner Mongolia Autonomous Region, as the donor. The average weight is between 45 and 76 kg, the age is 2 to 3 years old, the body condition is good, and there is no reproductive disease. The 2-3-year-old Ujimqin sheep with good body condition and no reproductive diseases had 3-5 parity of donors and recipients. The semen collection rams have strong libido, good semen quality inspection, and sperm motility above 0.6. Free access to food and water, natural light and supplementary light (light 16h / d), the temperature in the sheep house is 10 ~ 25 ℃, the diet is forage and premix. After embolization, each experimental sheep was fed at least 0.5 kg of carrots every day to supplement sufficient vitamins.

[0035] The donor sheep 14 days before embolization (CIDR) were selected as the experimental group donor sheep injected with cloprostol (Ningbo Sansheng, Pun...

Abstract

The invention provides a method for improving the breeding efficiency of livestock. Specifically, the invention provides an application of prostaglandin F2alpha or a homologue thereof in improving the superovulation efficiency of livestock, and a method for improving the superovulation efficiency of the livestock.

Description

technical field [0001] The invention belongs to the field of animal husbandry or veterinary medicine, and specifically relates to the application and method of prostaglandin F2α in improving the reproductive efficiency of sheep. Background technique [0002] Nowadays, the introduction process of foreign high-quality breeding stock is cumbersome, and the inspection and quarantine time is too long, which not only takes time and effort, but also increases the risk of disease transmission. Using embryo transfer technology to replace the introduction of breeding stock by introducing embryos from superior breeding stock can reduce the cost of keeping live animals and at the same time reduce the possibility of disease transmission. Embryo transfer technology can not only give full play to the potential of high-quality female animals in livestock breed improvement and population expansion, but also enable high-quality breeding stock genes to be inherited stably, and can effectively ...
