Pig feed additive, as well as gunk and mixed batch thereof

Abstract

The invention discloses a pig feed additive, as well as a gunk and a mixed batch thereof. The feed additive disclosed by the invention contains the following components in parts by weight: 5-10 parts of glycine betaine, 10-20 parts of an acidifier, 2-8 parts of algal polysaccharides, and 5-10 parts of crystal inulin. By using the feed additive disclosed by the invention to feed a pregnant sow, especially the constipation of the sow with high gestational age can be relieved; the birth number and healthy piglets can be increased; the fetiferous capacity of the sow is also increased.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a pig feed additive and its premix and batch. Background technique [0002] Pregnant sows in large-scale pig farms are kept in stalls for 114 days, and 0-30 days are the early stages of pregnancy. During this period, fertilized eggs implant on the inner wall of the uterus and develop into the earliest embryos, which determine the number of sows to produce in the future. The feed intake of sows during gestation needs to be strictly controlled, and frequent problems include constipation, miscarriage, and return to oestrus. If the above phenomena occur in sows, it will increase the number of non-production days in breeding, affect production performance and breeding benefits. The compound feed for pregnant sows on the market generally only meets the minimum needs of sows for protein and energy, and increases the content of folic acid, vitamin E, and selenium in the premix. However, in terms of f...

AI Technical Summary

Problems solved by technology

The feed intake of sows during gestation needs to be strictly controlled. Frequent problems include constipation, miscarriage, and return to oestrus. If the above phenomena occur in sows, it will increase the number of non-production days in breeding, affect production performance, and breed benefits

The compound feed for pregnant sows on the market generally only meets the minimum needs of sows for protein and energy, and increases the content of folic acid, vitamin E, and selenium in the premix. However, in terms of function, it is lacking in regulating intestinal function and protecting embryonic development.
