Method for propagating market hog

Abstract

The invention discloses a method for propagating market hogs. According to the different growth and physiological stages of the market hogs, the growth of the market hog comprises the stages of lactation and luring, weaning and stress, pigling breeding, growing development and beef gain, fodder with good nutrition, smell, and luring performance is provided in the stage of lactation and luring; fodder with diarrhea resistance and high nutrition concentration and capable of keeping the healthy of intestinal tract is provided in the stage of weaning and stress; fodder capable of strengthening immunity, promoting growth and exercising the intestinal tract is provided in the pigling breeding; fodder for increasing nutrition and protein synthesis is provided in the stage of growing development;the fodder with high energy and high amino acid is provided in the beef gain. According to the method, the fodder is schemed according to the physiology and development stage and the stress conditions; the method has the advantages of low mortality, quick growth speed, short propagation period, low feed conversion ratio, high weight and the like; in addition, the propagation cost of the market hog is lowered, and the economic benefits of propagating market hog are improved.

Description

technical field [0001] The invention relates to an animal breeding method, in particular to a fat pig breeding method. Background technique [0002] At present, most farms feed finishing pigs with three types of feed in three stages, ignoring the preparation of post-weaning feed, and feeding the same feed before weaning and two weeks after weaning, resulting in strong weaning stress. Weaning stress is the greatest stress in pig farming, and it is also the period with the highest mortality rate. The feed of piglets is changed from whole-milk diet to dry feed. At this time, weaned piglets are in a period of strong growth and development, but their digestive function and disease resistance are not strong enough. The drastic change of diet and the change of environment will have a strong impact on piglets. of stress. Piglets during this period usually have: [0003] l) Weaning stress. Early weaning stress mainly includes three aspects: separation of mother and offspring, tra...

AI Technical Summary

Problems solved by technology

The problem with early weaned piglets is that the passive immunity acquired by the piglets through mother's milk is interrupted, while the piglet's own immune system is not yet fully developed

[0005] 3) Reduced digestive enzyme activity

[0006] 4) Insufficient digestive physiological function and bacterial infection

Although this feeding method alleviates the stress response of pigs to a certain extent, it still has the disadvantages of single feed in the suckling piglet stage, waste of feed in the later stage, long feeding cycle, high feed-to-meat ratio, and low weight of pigs when they are slaughtered.
