The male rabbit needs to develop well, has a strong physique, and has a strong sex drive to complete the breeding task. Overweight and overweight are not suitable for breeding.

The fertilization ability of male rabbits depends on the quantity and quality of semen. The quality of semen is closely related to the nutrition of male rabbits, especially protein, minerals, vitamins and other nutrients, which play an important role in ensuring the quality of semen. . The relationship between the production of semen and the quality of the protein in the feed is greatest, and animal proteins have a more pronounced effect on the production and action of semen. Adding animal feed to the diet can increase sperm motility and improve fertilization.

Practice has proved that if male rabbits with poor semen quality are fed to bean cakes, peanut cakes, bran, and leguminous feeds such as milk vetch, Chinese wolfberry, and gardenia, the quality of semen is significantly improved. Vitamins also have a significant effect on semen quality. For example, when the vitamin content of male rabbits is lacking, the number of spermatozoa is small, and there are many abnormal sperms; if the vitamins in the diet of the male rabbit are insufficient, the reproductive organs are not fully developed, the testicular tissue is degraded, and the sexual maturity is delayed. It can be corrected when feeding grass, pumpkin, carrots, barley malt, lettuce, etc. Phosphorus is an essential element for the formation of nucleoproteins and is also necessary for the production of semen. When grains and bran are mixed in the diet, phosphorus is not deficient, but attention should be paid to the supply of calcium. The supply of calcium and phosphorus should be 1.5:1 2:1. Concentrates can often be supplemented with 2% to 3% of bone meal, eggshell powder or shell powder, etc., and calcium and phosphorus will not be lacking. In addition to paying attention to nutrition, the feed for male rabbits should also focus on the long-term nutrition. The change of feed affects the quality of semen very slowly. Therefore, when male rabbits with poor semen quality are switched to high-quality feed to improve their semen quality, they can take up to 20 days to be effective. Therefore, attention should be paid to adjusting the proportion of diets 20 days before. During the breeding period, the amount of feed should also be increased accordingly. For example, when male rabbits are bred twice a day, 30% to 50% of the concentrate should be added to the amount of feed. At the same time, according to the intensity of breeding, animal feeds should be appropriately increased to improve the quality of semen and increase the conception rate. As a kind of feed for male rabbits, it can be adapted to local conditions and locally sourced, but requires high nutritional value, easy digestion, and good palatability. Pay attention to supplementing mineral feeds. Add 1 to 2 grams of salt and a small amount of eggshell powder and oyster shell powder to the concentrate each day. The above suggestions are for reference only.

A Soxhlet extractor is a piece of laboratory apparatus[1] invented in 1879 by Franz von Soxhlet.[2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve a larger amount of material.
