Description

technical field [0001] The invention belongs to the technical field of feed composition and feed processing, and in particular relates to a special compound feed for boars and a preparation method of the compound feed. Background technique [0002] In pig farming, the number and quality of piglets on a farm largely depends on the quality and quantity of boar semen. In the case of natural mating, a boar can breed 600-800 piglets a year; while using artificial insemination technology, an excellent boar can breed more than 10,000 piglets a year, and the service life is about 3 years. However, due to the high frequency and intensity of artificial semen collection, it is easy to lead to a decrease in boar's libido, decreased ejaculation volume, lower semen quality, and even oligospermia, weak semen, no sperm, or dead sperm, resulting in a lower conception rate of sows. However, in actual production, due to the small amount of boar breeding, a large number of users do not use spe...

Problems solved by technology

[0009] In the boar feed of the prior art, Chinese herbal medicines are mostly used to improve the immunity of boars and improve the quality and quantity of semen, but there are many varieties of Chinese herbal medicines, and the quality of Chinese herbal medicines is difficult to distinguish, and the stability of efficacy and duration of action are difficult to grasp

In addition, there are boar feeds that can improve the quality of boar semen and increase the amount of semen from the nutritional point of view. Fertilization rate; in order to maintain the boar's body condition, although the boar's nutritional needs can be met after limited feeding, the boar lacks a sense of satiety, the boar is restless, and stereotyped behaviors are common. These conditions will affect the feeding effect and affect the boar. pig reproductive performance
