Embodiment 1

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

[0018] Twenty-four healthy weaned three-month-old Boer goats of the same strain, similar body weight, were randomly divided into 4 groups, of which three groups were the experimental group, and the other group was the control group. The experimental group was fed diets with different concentrations of vitamin E. shown in Table 1.

[0019] Table 1 Feeding amount of vitamin E in different groups

[0020]

[0021] After 5 months (at sexual maturity), they were slaughtered, and the testis of the same side were taken for tissue sectioning, and the sperm development was observed by microscope.

[0022] Section making process: sampling→fixing→dehydration→transparency→wax dipping→embedding→sectioning→staining→mounting→observation (MOTIC pathological image analysis system).

[0023] The specific operations are:

[0024] 1. Material sampling: After washing the obtained s...

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 andimprove 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 male animal sex organ development and sperm development. Background technique [0002] As the provider of sperm, the male animal has an important influence on the reproductive performance of the female animal. The quality of the semen directly affects the fertilization and lambing of the female animal. [0003] Sperm (Sperm) is a special cell produced by the gonads of male animals. Only viable sperm can reach the female reproductive organs to function and survive for a period of time. In order to maintain its life, sperm must carry out complex material metabolism activities in vivo and in vitro, among which are mainly glycolysis and respiration of sperm. There is a lot of oxidation in the metabolic process. If the oxidation products are not removed in time, it will cause great damage to the body. Vitamin E can not only directly scavenge free radicals generated by phys...
