Abstract

The present invention provides a special precise feed for three-hybrid replacement gilts. The special precise feed comprises, by mass, 45-60% of corn, 10-15% of soybean meal, 15-25% of a crude fiber raw material, 0.8-1.5% of a calcium source, 0.6-1.2% of a phosphorus source, 0.4-0.5% of a salt, and the balance of a vitamin premix and trace minerals.. The crude fiber raw material can prolong the satiety time, reduce starvation stress caused by limited feeding of pregnant sows, reduce occurrence of stereotyped behaviors, solve the problems that sows are prone to stress, the embryo implantation rate is low and abortion is prone to occurring after the three-hybrid sows are pregnant, increase the daily ration fiber level, remarkably improve the plasma progesterone level and increase the embryosurvival rate; and the calcium source, the phosphorus source, the vitamins and the trace elements guarantee bone development so as to prevent the replacement gilts from easily exceeding the standard in weight due to the fact that the growth speed of the three-hybrid gilts is high.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to three-element gilt special precision feed. Background technique [0002] Affected by African swine fever, the stock of breeding pigs has dropped sharply. Due to the hidden dangers of biosecurity, some pig farms dare not introduce gilts from outside. When there are no breeds to introduce and no pigs to raise, many pig farms cannot replace traditional binary breeding pigs with ternary hybrid sows to restore production capacity. There are many differences between commercial triple sows and binary breeding pigs. Through nutritional regulation, the growth performance of sows and their offspring can be improved. The problems of three-element sow breeding include: nutrition in the cultivation stage, unclear puberty, poor motherhood, uneven performance of offspring, and even genetic defects (genetic diseases). Sanyuan sows, also known as commercial meat pigs, have a genetic backgro...
