Breeding and feeding method for special wild boars

Abstract

The invention discloses a breeding and feeding method for special wild boars. According to the method, purebred male wild boars are selected to be used as male parents, American duroc purebred female sows are adopted as female parents, the special wild boars with the wild boar blood relationship content being 62.5 percent can be obtained after the hybridization, and in addition, feeding management such as domestication, coarse fodder addition in different physiological periods is carried out. The technical measures of hybridization, grading hybridization, back crossing, inter-mating, hybridization in strains, hybridization between strains, oriented culture, purification and rejuvenation and the like are adopted, the special wild boars obtained after the treatment have strong breeding power, the annual yield is more than 2.2 boars, the growth speed is high, the body weight of 8-month-old commodity growing and fattening boars can reach 90 to 100kg, the feeding is easy, the disease resistance capability is high, the meat is fresh, tender and delicious, the palatability is good, the color is bright red, the types of amino acids are more, the nutrition is more complete, particularly, the linoleic acid content reaches 17.5 percent, and the nutrition is rich.

Description

technical field [0001] The invention relates to a method for breeding and raising boars. Background technique [0002] Wild boar, also known as wild boar (Sus scrofa), has a very wide distribution range. Wild boars in China are mainly distributed in the three northeastern provinces, Yunnan-Guizhou, Fujian, and Guangdong. On the one hand, the number of purebred wild boars has been drastically reduced due to factors such as human hunting and the sharp reduction of living environment space, and has been listed as an endangered species by many countries. However, purebred wild boars have slow growth, light weight, limited number of wild boars, thick meat, thick skin, poor meat taste, etc. It is not suitable for simple domestication and promotion, and wild boars are in estrus seasonally, with few litters, and are not easy to raise. . And people seek wild game and improve taste and the requirement for nutritional value is constantly increasing. [0003] In order to solve the ab...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned two special wild boars with 75% wild boar blood have greatly improved in terms of meat quality, nutrition and yield, they still have the following disadvantages: First, their reproductive capacity is poor, and the best reproductive capacity is 2 The second is that the production speed is slow, and the weight of the full-year-old can reach 90 kg, and the breeding cycle is long; the third is that the palatability is poor, and there is a certain smell; the fourth is that it is irritable, difficult to raise, and even more difficult to raise on a large scale. , poor economy; fifth, the performance of nutritional value needs to be improved
