Sow pregnancy early stage compound feed for promoting sow welfare and improving sow reproductive performance, and processing method thereof

Abstract

the invention discloses a sow pregnancy early stage compound feed for promoting sow welfare and improving sow reproductive performance, and a processing method thereof. The compound feed is composed of the following components in percentage by mass: 32-40% of corn, 27-35% of wheat, 10-15% of soybean meal, 8-14% of dietary fiber, 0.1-0.2% of microecological preparation, 0.025-0.03% of carnitine, 0.2-0.3% of compound trace elements, 0.03-0.04% of compound vitamins, 0.05-0.06% of choline, 0.02-0.04% of phytase, 0.04-0.06% of anti-mildew agent, 0.15-0.2% of mycotoxin adsorbent, 0.8-1.2% of calcium monohydrogen phosphate, 0.1-0.2% of salt, 1-1.2% of stone powder and 0.9-1.0% of zeolite powder. The processing method includes the following steps: carrying out cleaning sorting, screening and crushing of the bulky raw materials of corn and wheat, adding the various raw materials into a mixer according to the formula amount and carrying out uniform mixing, and performing steam conditioning of texture, pelletizing, screening, cooling and packaging to get the finished product. The sow pregnancy early stage compound feed meets nutritional requirements of a sow in the pregnancy early stage, can promote the fetal development and the mammary gland development of sows, and can improve the maternal and fetal immunity.

Description

technical field [0001] The invention belongs to the technical field of feed, and relates to a sow pre-pregnancy compound feed capable of improving sow welfare and enhancing sow reproductive performance and a processing method thereof. Background technique [0002] The sow is the core group of the whole pig farm, and the reproductive performance of the sow determines the productivity of the pig farm. The gestation period of sows can be divided into three stages, and each stage has different nutritional needs. In the early stage, it is mainly used to ensure the implantation of the fetus and maintain the body condition of the sow. In order to ensure the smooth implantation of the fetus in the early pregnancy and improve the survival rate of the embryo, feed restriction is generally adopted to limit the energy intake of sows in the early pregnancy. At the same time, if the feed intake during pregnancy is too high, the feed intake during lactation will be significantly reduced. ...

AI Technical Summary

Problems solved by technology

[0005] At present, low nutritional level and low feeding amount are generally adopted for sows in the early pregnancy on the market. The sows’ appetite for food cannot be satisfied for a long time. Lifetime reproductive performance is adversely affected and sows cannot be fully utilized to their productive potential
