Description

technical field [0001] The invention relates to the field of boar feed, in particular to a feed formula for boars and its preparation and use methods. Background technique [0002] Traditionally, the research on the fertility of male animals involves two aspects of genetic behavior and feeding. For pigs, there have always been relatively few researches focusing on boar nutrition. Pigs practice natural mating. In fact, the effect of nutrition on the reproductive performance of sows is very limited, because the amount of sperm contained in the semen ejaculated by a boar is quite huge. Factors that become more important include feeding conditions and required nutrients. Based on the research of scholars, people not only have mastered some basic nutritional requirements of boars, but also need to consider factors such as body weight, growth rate, number of matings and environmental conditions. Of course, the nutrition of boars must also pursue a balance. On the one hand, to m...

Problems solved by technology

Based on the research of scholars, people not only have mastered some basic nutritional requirements of boars, but also need to consider factors such as body weight, growth rate, number of matings and environmental conditions. Of course, the nutrition of boars must also pursue a balance. On the one hand, to meet the nutrition needed to achieve the maximum semen production, on the other hand, it is necessary to control the increase of the boar's body weight to prevent lameness, such as: the invention patent application with the publication number CN102845633A, which proposes to add in the feed formula Chinese herbal medicine powder has the functions of warming kidney yang, nourishing kidney yin, and strengthening bones and bones. It also has certain effects in improving the quality of boar semen and promoting the growth of bone cells. In actual use, the amount of Chinese herbal medicine powder used is particularly important. Its effect is not obvious, and excessive amount may cause harm to the health of boars. Therefore, as a commercial feed, the use of Chinese herbal medicine powder is bound to be risky
