A special compound feed for boars and its preparation method

Abstract

The invention relates to a special compound feed for boars and a preparation method of the feed, and belongs to the fields of feed compositions and feed processing. The compound feed mainly includes the following raw material components in parts by weight: corn 48.5-57.5, soybean meal 14-18, stone powder 0.5-0.9, wheat bran 5-13, choline chloride 0.1-0.3, soybean hull 1-5, Soybean oil 1‑2, rice bran meal 1‑3, steamed fish meal 1‑3, composite premix 1, alfalfa meal 1‑3, puffed linseed 2‑5, lysine 0.2‑0.5, taurine 0.3‑ 0.7, baking soda 0.15-0.2, L-threonine 0.01-0.02, mycotoxin adsorbent 0.03-0.05, Danquinol No. 1 0.02-0.03, glucose 0.5-1. It can increase the semen quantity of boars, improve their sperm motility and sperm density, reduce the sperm deformity rate and improve the fertilization rate.

Description

Technical field [0001] The invention belongs to the technical field of feed composition and feed processing, and specifically relates to a special compound feed for boars and a preparation method of the compound feed. Background technique [0002] In the pig industry, the number and quality of piglets on a pig 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; 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 high intensity of artificial semen collection, it is easy to cause the boar's libido, ejaculation volume and semen quality to decrease, and even the phenomenon of oligospermia, weak sperm, azoospermia, or dead sperm occurs, which reduces the conception rate of sows. In actual production, due to the small number of boars raised, a large number of users do not use...

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
