Embodiment 1

[0025] Embodiment 1 is used to improve the preparation and preparation method thereof of sheep superovulation quantity and quality

[0026] Raw materials: melatonin, 75% ethanol solution.

[0027] Preparation method: dissolve melatonin with 75% ethanol solution, stir evenly, and prepare melatonin ethanol solution with a melatonin concentration of 5 mg / mL, and all operations are completed in a dark room.

Embodiment 2

[0028] Embodiment 2 is used for improving the preparation of sheep superovulation quantity and quality and preparation method thereof

[0029] Same as Example 1, the difference is that the 75% ethanol solution is replaced with absolute ethanol.

experiment example 1

[0030] Experimental example 1 Method for improving embryo production efficiency in sheep superovulation.

[0031] 1. Sheep superovulation treatment

[0032] Put a progesterone vaginal suppository (CIDR) into the vagina of the donor sheep on any day of the estrus cycle. This day is the first day, and intramuscular injection of FSH (the total amount is 200-280IU, domestic, such as Ningbo Sunshine Pharmaceutical Co., Ltd.), a total of 8 reduction injections in 4 days, CIDR was taken out at the same time as the seventh FSH injection, and estrus was 24-48 hours after the CIDR was taken out.

[0033] 2. Subcutaneously inject 2 mL of the injection prepared in Example 1 to the sheep with estrus symptoms after superovulation treatment:

[0034] Healthy donor ewes and recipient ewes with good reproductive performance were selected from the breeding farms (Beijing Aoxin Animal Husbandry Co., Ltd. and Hebei Province Zunhua Yahua Animal Husbandry Co., Ltd.), and they had free access to fo...

Abstract

The invention relates to the field of veterinary medicine for animal husbandry, and particularly provides a method for improving superovulating quantity and quality of sheep. The method comprises the following steps: injecting the sheep with estrous symptoms after superovulating treatment by using an injection with an effective component of melatonin through subcutaneous injection, wherein the injection dosage of the melatonin is 1-4 mL for each sheep (the melatonin concentration is 5 mg / mL). Animal experiments show that by the method, on the sixth day after insemination of a ewe, the total number of morulae / blastocysts flushed and the number of available embryos can be significantly increased, ova can be matured and the quality of inseminated embryos can be improved.

Description

technical field [0001] The invention relates to the field of animal husbandry and veterinary medicine, in particular to a method for improving the quantity and quality of sheep superovulation. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's demand for mutton, goat milk, and wool is increasing day by day, which puts enormous pressure on the sheep industry, and traditional sheep breeding and management methods can no longer the needs of the people. Sheep embryo transfer technology is a biotechnology developed in the past 40 years. Utilizing this technology can give full play to the reproductive potential of excellent ewes, and then expand the high-yielding herd, and it is also an effective means of breeding work. [0003] Embryo transfer is the process of taking out the early embryos of a good female animal after mating and fertilization, and transplanting it into another female animal of the...
