Abstract

The invention discloses a composition for improving the conception rate of ruminants subjected to synchronization of ovulation and timed-insemination as well as a preparation method and application thereof. The effective component of the composition is melatonin with the concentration of 10-20 mg / mL. Animal experiments prove that when the composition provided by the invention is used together withinjection of GnRH at the last time in a synchronization of ovulation and timed-insemination program for ruminants, reproductive hormone in animal bodies can be regulated to secret, the content of luteinizing hormone LH and progesterone in pregnant female animals can be increased, which can improve ovum quality, promote ovulation, and then improve the conception rate of ruminants subjected to timed-insemination.

Description

technical field

[0001] The invention relates to the field of animal husbandry and veterinary medicine, in particular to a composition for improving the pregnancy rate of ruminant synchronous ovulation and timing insemination, as well as its preparation method and application. Background technique

[0002] In recent years, due to the gradual increase in the unit yield in the dairy farming industry, the breeding pregnancy rate of the dairy cows has shown a downward trend, and the calving intervals of dairy cows are long, which seriously affects the economic benefits. How to improve the reproductive efficiency of dairy cows has become an urgent task restricting the development of the industry. Timed Artificial Insemination (TAI) refers to a technology in which a group of dairy cows are in estrus and ovulate at the same period, and artificial insemination is performed regularly. This technology has good effect and high efficiency, and has been applied in many large pastures. T...
