A kind of patterned feeding method for sows and feed during pregnancy

Abstract

The invention belongs to the technical field of cultivation, and particularly relates to a sow patterned feeding method, and smashed feed for pregnant sow with low protein and high fiber in early andmedium periods of gestation. The sow feed in pregnant period is fed for 0-90 days after hybridization, and the specific feed amount is determined upon P2 backfat and body condition score. The sow feedin pregnant period is based on corn, bean pulp, extruded soybean, fine wheat bran, rice bran and others, and especially added with alfalfa grain, expanded flaxseed, fermented astragalus membranaceus,and Spanish bayonet plant extractive. The ratio of digestible amino acid is proper. By adopting the patterned feeding method, combining with sow feed in pregnant period, and applying a scientific feeding method, the sow weight and body condition are moderately controlled, the health birth number can be correspondingly increased, the sow birth performance is improved, and the sow mortality is reduced, and the sow feeding benefit is increased.

Description

technical field [0001] The invention belongs to the field of breeding technology, and in particular relates to a patterned feeding method for sows, and low-protein, high-fiber broken feed for sows in the early and middle stages of pregnancy, so as to improve the production performance and lifetime reproductive rate of sows . Background technique [0002] With the rapid development of my country's pig industry, the level of my country's pig raising technology has matured, and the scale of pig raising has formed a large-scale intensive development. At present, there are two major problems restricting the sustainable and healthy development of my country's pig industry. One is the high cost of feed raw materials, especially protein raw materials, especially soybean meal, which is mostly dependent on imports, which seriously threatens the development and safety of China's feed; the other is large-scale pig farming. The environmental pollution caused by it has become the most fun...

Problems solved by technology

However, the requirements for equipment and breeders are relatively high, which is not suitable for the current national conditions.

Domestically, pregnant sows are mainly reared in individual stalls, usually using restricted feeding methods, but the feed generally has insufficient compound dietary fiber, and most feeds have a crude fiber content of 5-6% and a relatively high crude protein content 14.5-15%, causing constipation and stereotyped behaviors in sows

In addition, there is a lack of reference indicators and judgment standards for feeding modes, and the feeding modes are relatively extensive or poorly operable. Individual differences in sows are not considered. The sows in a pig house are fed almost the same amount, making them lean The sows are undernourished, the body condition recovery is not good, and the over-fat sows are fatter, which reduces the number of healthy piglets, reduces the parity of sows in the sow breeding industry, increases the elimination rate, and lowers the production performance of sows, which seriously affects Benefits of breeding sows
