Special feed for improving boar semen quality

Abstract

The invention discloses a special feed for improving boar semen quality. The digestible energy of the special feed is 3100-3200 kcal/kg, the digestible lysine content is 0.75-0.8%, and the protein level is 15.5-16.5%. Research finds that: the digestive energy level has very significant influence on the number of effective sperms. Protein concentration is related to sperm motility rate and is affected by the protein level. The digestive energy level has a significant influence on the sperm malformation rate, and the protein level also has a significant influence on the malformation rate. The special material of the invention has a remarkable effect on improving the sperm motility, the malformation rate, and the seminal fluid volume and density of boar.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed for improving the quality of boar semen. Background technique [0002] Boars are very important to the fertility of pig herds. If the quality of boar semen is poor, the performance of the entire pig farm production herd will be extremely adversely affected. The value of boars is expensive, but due to the small size of the group, they are often seldom paid attention to; at the same time, due to the small number of boars, the long semen production cycle, and many influencing factors, the experiment is difficult. rare. [0003] Generally, energy feed accounts for about 60% of the feed for boars. If it is too high, it will cause obesity, loss of libido, and sperm development is not perfect; if it is too low, it will affect the production of sperm. Protein and amino acid are the material basis of sperm formation, which have a great impact on semen volume, quality and spe...
