One is the feed off. The lean meat type pigs require about 3,100 kcal per kilogram of digestive energy, 16% of crude protein at 20 to 50 kilograms, and 14% of crude protein at 60 to 90 kilograms, and lysine, methionine, and cystine. And important trace elements and vitamins must be in a certain proportion. In order to facilitate pig raising, “concentrates†specially produced by feed mills can be purchased. According to the instructions, a certain percentage of corn, bran, rice bran, and bean cakes, etc., can be formulated to meet the requirements of full-price compound feed without having to buy various products. All kinds of trace elements and additives. If you can not buy "concentrate", can be formulated according to the following formula: 1 pig body weight 10 to 20 kg: 60.2% corn, wheat bran 4%, 28% of soybean cake, fish meal 4%, yeast 2%, salt 0.3 %, bone meal 0.5%, compound trace elements 0.5%, multivitamins 0.5%. 2 Pig weight 21-35 kg: 63% corn, 10.2% bran, 13.5% soybean cake, 6% rapeseed cake, 5% fish meal, salt 0.3%, bone meal 1%, 0.5% compound trace elements, multivitamin 0.5 %. 3 Pig weights 36-60 kg: 62% corn, 12% bran, 5% bran, 10% soybean meal, 5% rapeseed cake, 3.5% fish meal, 0.5% salt, 1% bone meal, 0.5% compound trace elements Multivitamin 0.5%. 4 The weight of the pig is 61-90 kg: corn 57%, bran 18%, gluten 6%, soybean meal 9%, rapeseed cake 5%, yeast powder 3.3%, salt 0.5%, bone meal 1%, composite trace elements 0.1 %. The second is keeping the customs off. Adopt the "open front control" breeding technology. "Before open" means that pigs take multiple feedings a day or allow the pigs to feed freely before 50 kg of body weight. The feed is not limited. After 50 kilograms in weight, except for ensuring that there is sufficient drinking water, only two meals a day are provided, and only 80% of all meals are fed, which is the so-called “post-controlâ€. Because after 50 kilograms of pigs, fat is mainly deposited and growth is accelerated. If the pigs are fed too full, the pigs will grow more fat and reduce lean meat. The third is the regulation and control. Tests have shown that when a pig weighs 40 to 60 kg, the daily growth of lean meat is 288 g and the fat is 280 g. After 90 kg, the daily growth of lean meat is only 120 g, and the fat is 2 times that of lean meat. the above. Therefore, lean-type pigs must be controlled in the 90 ~ 100 kg slaughter market.
