Method for breeding small black pigs

Abstract

A method for breeding small black pigs comprises the steps of selecting purebred Lvchun wild boars to crossbreed Xiaodonggua sows to produce piglets. The method for feeding the piglets comprises the steps: feeding the piglets three times daily, feeding with thoroughly cooked buckwheat noodles once in the morning and evening daily, feeding with fresh sweet potato leaves and tender tip stems once atnoon daily, after the piglets grow to 30 kg, starting to feed with thoroughly cooked buckwheat noodles once at noon daily, stocking in the field at other time, and retracting the pigs into a pigpen in the evening; at the same time, after the piglets grow to 25-30 kg, starting to feed with water obtained by boiling fresh tithonia diversifolia leaves once monthly, and carrying out disease prevention and control, to prevent the pigs from getting ill; and starting to feed for 10-12 months from the piglets, and slaughtering when the weight of the small black pigs reaches 65-75 kg. The method can improve the farrowing rate and the survival rate, the pigs have strong disease resistance, and the pork has fine, smooth, delicious and fragrant in quality and has no peculiar smell and foreign flavor,and the pigs are suitable for industrialized large-scale breeding.

Description

technical field [0001] The invention belongs to the technical field of pig breeding methods. Background technique [0002] In Luchun County, Honghe Prefecture, Yunnan Province, there is a kind of winter melon pig, commonly known as little black pig, also called little winter melon pig. It is a local pig breed domesticated from native wild boar. It has strong adaptability, strong meat flavor, It has the advantages of delicious meat, high collagen content and rich nutrition. The price of small black pork on the market is 50% higher than that of other pork. Therefore, the small black pig breeding industry has a good market prospect. However, the small black pigs are small in size and have low meat production rate. In order to increase the meat production rate, most farmers use Duroc male pigs and small black pig sows for crossbreeding. 8-10 small piglets, not only the litter rate is not high, but also in the breeding process, the feed is mainly corn, the breeding cost is high...

Problems solved by technology

However, the small black pigs are small in size and have low meat production rate. In order to increase the meat production rate, most farmers use Duroc male pigs and small black pig sows for crossbreeding. 8-10 small piglets, not only the litter rate is not high, but also in the breeding process, the feed is mainly corn, the breeding cost is high, the meat quality and taste of pork are also lower than that of small black pigs, and the disease resistance of pigs is also lower. Therefore, we have to add other excipients and pharmaceutical ingredients to strengthen the body and resist diseases in the feed

Although these methods have enhanced the disease resistance of pigs to a certain extent, they will affect the appetite of pigs and reduce the amount of food intake, thereby affecting pork quality and meat production rate.

In addition, the polluted environment of the pig breeding area also provides conditions for the spread of the disease, causing farmers to intensify vaccination, resulting in increased breeding and management costs
