Problems solved by technology

The existing breeding methods of black pigs mostly use pens to raise black pigs. The range of activities of black pigs is narrow, which leads to muscle relaxation. Appropriate amount of outdoor training can not change the depressive growth environment of black pigs. In addition, a large amount of artificial feed is used to feed black pigs, which leads to The nutritional value of black pigs is greatly reduced, and the taste is not as good as pigs that eat natural food. The advantages of black pigs are not reflected, which reduces the market development prospects of black pigs

Embodiment 1

[0015] A free-range breeding method for black pigs, comprising the following steps:

[0016] (1) Select a small hillside with a height of 50 meters and a vegetation coverage rate of 60% as a free-range breeding ground for black pigs, and evenly plant honeysuckle, chrysanthemum, goosegrass, toad clothing, spinach, dandelion, and rootlets on the hillside Garlic, to ensure that the above-mentioned plants occupy 20% of the total area of ​​each mu of mountain land, and build a breeding base on the hillside and flat ground, which can be used for black pigs to rest, feed, and sow production;

[0017] (2) Mark the black pigs with a weight of more than 30 kg, hang a sign on the neck of the black pigs to record the signs of the black pigs, and send them to the hillside for stocking to ensure that there are no other large aggressive animals on the hillside. Set up feeding points on the ground, 5 per acre, supply corn, sorghum, wheat bran, soybean straw, sweet potato straw, potato seedlin...

Abstract

The invention relates to the field of black pig culture and discloses a free-range method for black pigs. The method comprises followings steps; (1) selecting hillsides with suitable height as free-range locations for black pigs; planting plants which can provide sufficient nutrients and prevent black pig diseases and building culture base at hill foot for management; (2) while free-range of the black pigs on the hillsides, tracking and observing; since the black pigs have different independence, setting forage points on the hillsides for black pigs that are weak in feeding and gradually training the adaptability of the black pigs, which is good for the accumulation of wild black pig genes; (3) while free-range on the hillsides for training adaptability of the black pigs to the natural environment, supplementing artificial forage for feeding at night to strengthen the black pigs and quick fatting, therefore increasing the economic benefit of culture. By means of the free-range method of black pigs, the pork has pure local flavor, the pork is delicious and has abundant nutrition, which has strong nourishing effect for the weak.

Description

technical field [0001] The invention relates to the field of black pig breeding, in particular to a free-range breeding method for black pigs.
