Black pig free-ranging method

Abstract

The invention discloses a black pig free-ranging method which comprises the following steps: selecting a sunny slope with a forest as a pig farm, enclosing the pig farm with an iron fence, arranging a pig house outside the pig farm, arranging a door for the pig house for communication with the pig farm, and arranging feeding troughs and drinking troughs in both the pig farm and the pig house; selecting weaned, strong, unwounded and disease-free black piglets for free-ranging, and before the piglets are settled, comprehensively disinfecting and sterilizing the pig house and the pig farm; for free-ranged black pigs, driving the black pigs into the pig farm after the black pigs are fed with concentrated food every morning, throwing grass at least once and ensuring sufficient water in the drinking troughs in that period, and late in the afternoon, driving the black pigs back into the pig house, and throwing the concentrated food once; periodically cleaning, disinfecting and sterilizing the pig house and the pig farm, and periodically replacing bedding straws. According to the method, a free-ranging form is adopted, so that the black pigs are closer to the nature, the quality of pork is improved, and the requirements of people on the black pork are further better met.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, in particular to a method for free-range breeding of black pigs. Background technique [0002] Black pigs have been domesticated in China for nearly 5,000 years. They are exquisite in size, sensitive in response, strong in disease resistance and fecundity, and resistant to cold. After the Western white pigs entered China in large numbers at the end of the last century, they were almost extinct. However, with the development of the economy and the needs of people's material culture, black pigs have returned to people's tables in recent years. They have attracted people's attention because of their tender meat and high nutritional and medicinal values. The breeding of black pigs has also gradually attracted the attention of farmers. However, in order to maximize profits, many farmers choose hormone-based growth feeds to achieve a short growth cycle and a fast growth rate for black p...
