Boar breeding method

Abstract

The method of raising boars, including the selection of pig breeds, feed preparation, feeding methods, breeding period management and peacetime management; it is characterized in that the selection of pig breeds and feed preparation methods are as follows: the local Dongsa soil pig in Yunnan is selected as the pig breed; Energy feed and green feed are prepared in a 1:1 ratio. By weight, the proportion of energy feed is: corn 55%-60%, soybean meal 18-22%, Anyou 1288 10-14%, wheat bran Accounting for 8-12%, the crude protein index of the prepared energy feed is 12-16; the green feed includes: wild boar grass, giant chrysanthemum, alfalfa, radish, chopped and mixed evenly, and the mixing ratio of each component is not limited. Through the feeding and management measures, the boars have a strong body, and the piglets obtained from the breeding have strong viability, which improves the ability of the original Dongsa pig breed to adapt to large-scale farming. Through feeding with energy feed and green feed, Coupled with proper field stocking, the quality, nutritional value and delicious taste of Dongsa pork are maintained.

Description

technical field [0001] The invention relates to a boar breeding 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 natural stocking, the pigs grow fast, have a short growth cycle, and have a high lean meat percentage, but the intermuscular fat content is not moderate, and they do 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 that flavor is in...

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.
