Method for feeding tri-crossbred pigs with feed containing silage whole maize

Abstract

The invention discloses a method for feeding tri-crossbred pigs with feed containing silage whole maize. Under low-energy high-fiber level of fermented maize straws added into the feed, the lean percentage can be increased effectively, pork output is increased, and feeding cost is reduced effectively. The method includes: (1) according to weights of the tri-crossbred pigs, dividing growth and development of the tri-crossbred pigs into two periods namely a growth period when the pigs are 20-60kg and a fattening period when the pigs are 60-115kg; (2) according to the different periods, designing methods for feeding the pigs with whole maize in a preservative manner, wherein in the growth period, an energy-protein ratio is 21.75-22.08, silage whole maize is 20-40%, and a mass ratio of the silage whole maize to complete compound feed is 1 / 4-3 / 2; in the fattening period, an energy-protein ratio is 24.25-24.85, silage whole maize is 40%-60%, and a mass ratio of the silage whole maize to complete compound feed is 2 / 3-3 / 2; (3) designing a formula according to ranges at the step 2), preparing daily feed, and feeding according to the different periods.

Description

technical field [0001] The invention relates to a feeding method for pigs, in particular to a method for feeding three-way pigs with feed containing ensilage whole plant corn. Background technique [0002] With the improvement of living standards and the enhancement of health awareness, pork is an important part of people's diet, and people's requirements for pork quality are constantly improving, and the demand for high-quality pork is also gradually increasing. The production of high-quality pork has become the focus of research in recent years. [0003] However, although with the rapid development of the pig industry, more and more high-quality pig breeds have been promoted in our country, the feed nutrition for them has not been well promoted, and most of the farmers have not strictly followed the requirements of pigs at various stages so far. Nutrients need to be fed, so that the pigs at all stages have not reached the ideal growth level, and the benefit of raising pig...

Problems solved by technology

[0003] However, although with the rapid development of the pig industry, more and more high-quality pig breeds have been promoted in our country, the feed nutrition for them has not been well promoted, and most of the farmers have not strictly followed the requirements of pigs at various stages so far. Nutrients need to be fed, so that the current pigs at all stages have not reached the ideal growth level, and the benefit of raising pigs is low

At present, the research on pig feed products on the market mostly only focuses on nutrition research and formula optimization at a certain stage, but lacks the corresponding supporting feeding technology that organically combines feed at each stage to achieve the best growth effect and reduce feed cost.
