Breeding method for captive black pigs

Abstract

The invention discloses a breeding method for captive black pigs. The method comprises the following steps: step 1, seed selection: purchasing piglets which are strong in activity ability, free of diseases and within 20 days in age, wherein male parents and female parents are required to be black pigs, and the piglets are required to drink female milk to grow within at least 15 days; and step 2, selecting a mountain land which is flat in terrain, sufficient in water source and rich in vegetation as a breeding site, building an enclosing wall with the height of 1.6-2.8 m and the area of 7-9 square meters on the site to serve as a pig house, and meanwhile, building a free-ranging land with lawns to serve as a pig activity place. The invention relates to the technical field of black pigs. According to the captive breeding type black pig breeding method, genes of piglets can be increased through high-quality seed selection, meanwhile, a high-quality nutrient solution is used for feeding black pigs in a matched mode, the black pigs are reasonably trained, the bred black pigs are good in meat quality and large in physique, and the breeding time can be shortened through the breeding method.

Description

technical field [0001] The invention relates to the technical field of black pigs, in particular to a breeding method for captive black pigs. Background technique [0002] Black pigs have been domesticated in China for nearly 5,000 years. The Jiuchongtian Huanlongyan site in the Shungeng area of ​​the southern mountainous area of ​​Jinan and the Tu River Basin in Jiyang today are important places for the inheritance of animal husbandry in ancient times. However, due to the slow growth period and low body weight, the annual black pig is only 150 catties, so it was almost extinct after the western white pigs entered China in large numbers at the end of the last century. Tuhe black pig is a rare protected population in contemporary times. [0003] Because the growth cycle of black pigs is relatively slow, the output of black pigs is relatively low, so it is necessary to breed black pigs. However, through the existing breeding methods, the quality of black pigs produced is rela...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a breeding method for captive black pigs, which solves the problem that the quality of the produced black pigs is relatively poor, and the production speed is still relatively slow, the survival rate is low, and most of the black pigs have relatively poor systems. Weakness, which causes problems with smaller stature
