Embodiment 1

[0026] Example 1 Preparation for Improving Conception Rate of Dairy Cows and Preparation Method thereof

[0027] Raw materials: melatonin, vitamin E;

[0028] Preparation method: accurately weigh 0.4307mg vitamin E and 232.27mg melatonin, first dissolve 0.4307mg vitamin E in a 100mL volumetric flask with 75% ethanol solution, stir evenly, then add 232.27mg melatonin, stir evenly, set The volume was up to 100mL, and finally divided into 2mL injection doses. All operations were completed in a dark room.

Embodiment 2

[0030] With embodiment 1, difference is that the concentration of described melatonin is 10 -1 mol / L, the concentration of vitamin E is 10 -4 mol / L, and the vitamin E was dissolved with absolute ethanol.

Embodiment 3

[0032] With embodiment 1, difference is that the concentration of described melatonin is 10 -3 mol / L, the concentration of vitamin E is 10 -6 mol / L.

Abstract

The invention relates to the field of animal husbandry and veterinary medicines, and particularly provides a preparation capable of improving the cow conception rate, as well as a preparation method and an application of the preparation. An effective component of the preparation comprises melatonin with the concentration of 10<-3> to 10<-1>mol/L and vitamin E (Ve) with the concentration of 10<-6> to 10<-4> mol/L. The animal experiment proves that when in-vitro injection of the preparation is carried out on breeding at the same time, the damage of reactive oxygen species (ROS) to quality of ovum can be reduced, and egg-sperm binding is promoted to achieve fertilization. According to the preparation, the cow conception rate can be effectively improved, and the reproduction efficiency of cows is improved.

Description

technical field [0001] The invention relates to the field of animal husbandry and veterinary medicine, in particular to a preparation for improving the conception rate of dairy cows, a preparation method and application thereof. Background technique [0002] With the continuous improvement of people's living standards, the annual milk consumption is increasing day by day, but the number of breeding cows in China has been declining rapidly in the past two years. How to improve the reproductive efficiency of dairy cows is related to the speed of the expansion of dairy cows and the income of farmers. Vital interests are also an important indicator of scale farm production management. At present, the commonly used drugs to improve the reproductive efficiency of dairy cows are mainly gonadotropin drugs, which mainly promote the ovarian function of cows, such as promoting follicular development, ovulation and secretion of corpus luteum, and overcome the resulting reproductive obst...
