Boar breeding method

Abstract

The invention discloses a boar breeding method. The boar breeding method comprises techniques in boar breed selection, feed preparation, feeding pattern, mating period management and daily management, and is characterized in that boar breed selection and feed preparation are carried out in the way that a local boar in Dongsa of Yunnan is selected, and an energy feed and a green feed are mixed according to the ratio of 1:1, wherein the energy feed contains 55-60% by weight of corn, 18-22% by weight of bean pulp, 10-14% by weight of Anyou 1288 and 8-12% by weight of wheat bran; the crude protein index of the prepared energy feed is 12 to 16; and the green feed contains ragweed, giant chrysanthemum, alfalfa and radish which are cut up and uniformly mixed according to an unlimited proportion. Breeding management measures are adopted, so that the boar is robust, piggies bred by the boar have strong survivability, and the large-scale breeding adaptability of the original Dongsa boar breed is improved; and as the boar is fed with the energy feed and the green feed which are matched, and is additionally properly bred in the open country, the quality, nutritive value and fresh and delicious taste of Dongsa pork are remained.

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.
