Sow raising method

Abstract

The invention discloses a sow raising method which comprises breed selection, feed preparation, feeding mode and mating period management and is characterized in that: a, the Dongsa local pig growing in the plateau snow mountain region of Yunnan is selected as the breed; b, the green feed accounts for 60%, and the energy feed accounts for 40% by weight; the crude protein index of the prepared energy feed is 12.54 by weight; the green feed comprises wild pigweed, chicory, alfalfa and radish which are cut up and uniformly mixed; and the mixing proportion of each component is not limited; c, the feeding mode is that each sow is fed with the energy feed and the green feed at an average ratio of 2:3 everyday; and d, the matting period management comprises the steps of: a, manual check; and b, boar trial. The method disclosed by the invention improves the performance of the original breed adapting the large-scale farming, provides a method for breeding domestic traditional breed, creates conditions for expanding the raising scale and farming range, and lays foundation for the traditional breed with good meat quality to adapt to the market demand.

Description

technical field [0001] The invention relates to a sow feeding method. Background technique [0002] Most large-scale farms raise mostly foreign breeds (Duroc, York, Changbai), and feed pigs with the ratio of concentrated feed and energy feed. No green feed is added, and they are not resistant to rough feeding. There is a demand for feed protein content. High, the comprehensiveness of wild feeding is poor, and the disease antibody is not strong, it is easy to be attacked by viruses, and the fattening period is 6-7 months. Without the form of natural stocking, the growth rate of pigs is fast, the growth cycle is short, and the lean meat rate is high, but the intermuscular fat content is not moderate, and it does not have the tender and moist meat quality of local Dongsa soil pigs. Cause pork composition to be the structure that lean meat and fat meat clearly demarcate, cause the fat content of fat meat to be high, completely do not have fat meat to mix in lean meat, and seem ...

AI Technical Summary

Problems solved by technology

However, the original breeding method of Dongsa pigs is individual farming by farmers, mainly in the form of stocking and supplemented by feed. The growth is slow, and the fattening cycle is as long as 12-15 months, resulting in high breeding costs and relatively poor economic benefits.
