Method for feeding fat pigs

Abstract

The invention discloses a method for feeding fat pigs. Different feeds are fed according to different growth stages of the pigs; the growth stages of the pigs are divided into a survival stage, a development stage and a weight increment stage; the survival stage is 7 to 38 days, the development stage is 39 to 50 days, and the weight increment stage is 51 to 175 days; and the feed with function of enhancing immunity is fed at the survival stage, the feed with function of promoting functional completeness of each system of the pigs is fed at the development stage, and the complete feed for promoting weight increment of the pigs is fed at the weight increment stage. The method breaks through the traditional raising mode; the feed is designed according to the physical development characteristics of the pigs; and by adopting the method for feeding the fat pigs, the weight increment of the pigs is quick, the feed-meat ratio is low, and the feed is saved.

Description

technical field [0001] The invention relates to a feeding method for animals, in particular to a feeding method for fattened pigs. Background technique [0002] In the traditional method of raising pigs, the growth and development of pigs are divided into three periods, that is, the stage of small pigs (the growth period with a body weight of 20-35 kg), the stage of middle pigs (the development period with a body weight of 36-60 kg), and the stage of large pigs ( During the fattening period with a body weight of 61-90 kg or more), feeds at different stages are designed according to the nutritional demand characteristics of pigs in these three stages. In the feeding mode, the linear fattening method or the front-attack and rear-limit fattening method are mostly used. However, these feed designs and feeding patterns are aimed at increasing the weight of pigs in each growth period, focusing on indicators such as crude protein and digestible energy in the feed at each period, wh...

Problems solved by technology

However, these feed designs and feeding patterns are aimed at increasing the weight of pigs in each growth period, focusing on indicators such as crude protein and digestible energy in the feed at each period, while ignoring the need for piglets to eat breast milk smoothly and healthily. Transition to the important link of eating fattening feed will cause post-weaning stress, increased mortality and stagnant growth of piglets, which will affect the fattening effect, prolong the time for slaughter, and ultimately the overall economic benefits cannot be guaranteed
