Problems solved by technology

Since X sperm and Y sperm are only 0.007g / cm 3 The difference in density, density gradient centrifugation is difficult to separate the two accurately, and the centrifugation process can reduce energy vitality, thereby reducing the fertilization ability of sperm
Therefore, the effect of centrifuging X and Y sperm to control the sex of offspring rabbits is not ideal
Electrophoresis also has the problems of low separation efficiency and damage to sperm motility
In recent years, good results have been achieved in separating X and Y sperm by using flow cytometry, but the equipment is expensive and the separation speed is slow (300,000-350,000 sperm per hour), which is only suitable for large-scale breeding stations , should not be used in production
So far, there is no technology to effectively control the sex of offspring rabbits applied to production practice

Abstract

The invention relates to male rabbit feed beneficial to controlling sex of offspring rabbits and an application of the feed to increasing the female proportion of the offspring rabbits. The male rabbit feed contains the following raw materials in parts by mass: 15-20 parts of corn, 12-20 parts of wheat bran, 12-20 parts of soybean meal, 40-50 parts of grass powder, 1-2 parts of yeast powder, 0.02-0.05 parts of bile acid, 0.02-0.05 parts of dihydropyridine, 0.02-0.04 parts of selenium methionine and 0.02-0.03 parts of zinc glycinate. The feed disclosed by the invention has the advantages that the composition of rabbit body fluid can be adjusted and the microenvironment of fertilization can be changed; when the male rabbit feed disclosed by the invention is adopted and coordinated with corresponding female rabbit feed, the output rate of female baby rabbits can be increased by more than 15% on the original basis; and therefore, the male rabbit feed has a good application prospect.

Description

(1) Technical field [0001] The invention relates to a feed for male rabbits which is beneficial for controlling the sex of offspring rabbits, and its application in raising the ratio of female offspring of rabbits. (2) Background technology [0002] Using biotechnology to make animals produce female or male offspring of a predetermined sex has always been an important area of ​​concern in life sciences. Sex control technology has great significance in livestock production. First, by controlling the sex ratio of the offspring, the maximum economic benefits of sex-restricted production traits (such as lactation) and gender-affected production traits (such as growth speed, meat quality, etc.) can be fully utilized. Secondly, controlling the sex ratio of offspring can increase the intensity of selection and speed up the breeding process. It has been found in the production of rex rabbits that the comprehensive economic benefits of female rabbits are 25% higher than that of mal...
