Embodiment 1

[0017] This example takes the male lamb as the research object to illustrate the method of the present invention.

[0018] Select 24 healthy weaned three-month-old Boer goats of the same strain, similar in weight, and randomly divide them into four groups, three of which are experimental groups and one is the control group. The experimental groups are fed with different concentrations of vitamin E diets, specifically as follows: Table 1 shows.

Abstract

The invention provides a method for promoting the development of sexual organs and sperms of sires and feeds vitamin E to the sires from the weaning to the sexual maturity of the sires. The method of the invention can increase the weight of epididymides, the density of convoluted seminiferous tubules, the diameter of epididymides and the amount of spermatogenic cells, use the sires beforehand and improve the reproductive capacity and utilization years of herd sires. Additionally, the invention can also reduce tedious operations in keeping and improving semen quality and sperm motility in artificial insemination, improve the fresh precision quality used in artificial insemination and frozen semen so as to improve the quality of the artificial insemination and frozen semen, thus increasing the production efficiency from the source. The invention is easy and convenient in operation and significant in economic benefits.

Description

technical field [0001] The invention relates to animal husbandry, in particular to a method for promoting the development of male animals' sexual organs and spermatozoa. Background technique [0002] As the provider of sperm, the male animal has an important impact on the reproductive performance of the female animal. The quality of semen directly affects the fertilization and lambing of the female animal. [0003] Sperm are special cells produced by the gonads of male animals. Only viable sperm can reach the genitals of the female animal to play a role and survive there for a period of time. In order to maintain its life, spermatozoa must carry out complex material metabolism activities both in vivo and in vitro, mainly glycolysis and respiration of spermatozoa. There is a large amount of oxidation in the metabolic process, and if the oxidation products are not removed in time, it will cause great damage to the body. Vitamin E can not only act as an antioxidant to direct...
