The use of high-quality forage grass to raise pigs can not only reduce the cost of feed, but also increase the lean meat percentage of pork, which can greatly increase the economic benefits of pig production. The high-quality forages for raising pigs include: grain pods, Russian feed, bitter leeks, winter grazing 70 ryegrass, chicory, alfalfa, and white clover. The pastures fed by various types of pigs are: First, the pig (7 to 20 kg) To fully supply some high-quality, comprehensive nutritional piglet feed, in order to eat full, the protein content in the feed should reach 18%, calcium (Ca) content of 0.8 to 0.99%, while feeding a small amount of pasture fresh stems properly Leaves, remember not to feed too much, the amount of daily feed to 1 to 2 kilograms is appropriate, not more than 3 kilograms, generally feed fresh grass half an hour before feed. Second, the pig (20 ~ 60 kg) This stage is the most critical period for increasing lean meat ratio. It is also an important period for reducing pig raising costs through high-quality forages and saving concentrates. At this time, high protein content concentrates can be fed less, and high-quality pastures can be used to supplement protein in the concentrates. Insufficient calcium and vitamin supplements, as well as mineral supplements, generally have a daily dose of 4 to 6 kg of fresh grass or 15% of fine concentrate. (Preparation of concentrates: 70% corn, 20% bran, 10% concentrated feed or bean cake), and the daily feed amount of concentrate is 1 to 1.25 kg. Generally, fresh grass is fed half an hour before the feed is fed and twice a day. The ability of pigs to digest and utilize crude fiber is enhanced. The stress resistance and adaptability are greatly improved. The weight gain is fast. At this time, concentrates should account for 80% of corn and 20% of bran. It is not necessary to add any concentrate. Feed about 6 to 8 kilograms of pasture grass or 20% of the concentrate's grass powder. The amount of concentrate feed is 1.5 to 2 kilograms per day. Feed the fresh grass half an hour before feeding the concentrate and feed it twice a day. In the first half of the season, 2 to 3 kg of fresh grass, 2.1 kg of 90% corn and 10% bran mix were fed daily. How to raise sows empty phase: If the sow is too thin, more concentrate should be added. In general, sows are fed 0.5 to 1 kilograms of concentrate each day, and 8 to 10 kilograms of fresh grass or 20% to 30% of corn + 10% of bran are mixed with 60 to 70% of forage hay powder. 80 days after sow pregnancy, high utilization of various nutrients in feed, coupled with slow growth and development of embryos at this time, is the best time to save the fine material, its feeding method is the same as the empty phase. Third, pregnant sows From 80 days after sow is pregnant, to about 35 days after farrowing, appropriate energy and protein must be added to the feed to supplement calcium, add 20 grams of bone meal or 50 grams of fish meal daily, and increase the amount of concentrate from 0.5 to 1 kg/day to 1 ~ 1.5 kg/day, adjust the quality pasture to 5 to 6 kg/day. During the lactation stage, the feeding amount of concentrate is increased, and calcium is properly added. Under normal circumstances, concentrates use 60% corn + 30% bran + 10% sow concentrate feed or 50% corn + 30% bran + 18% The bean cake was fed with 2% bone meal. The amount of concentrate was 2.5 to 3 kg/day, and 8 to 10 kg of fresh grass was added. Feeding pigs generally does not require chopping or beating, and can be fed directly. However, forage grasses such as schizont, vanilla, and grasshoppers have poor palatability and can be chopped or beaten and fed into the concentrate.
