How to reduce the cost of raising pigs

Select species, heavy disease prevention scale pigs must be selected to raise "ternary" hybrid piglets, waist length, chest width, mouth short, after the buttocks plump, thick limbs, fight for food grab food Landrace, about g pigs for the best. It only takes about 160 days to reach 90~100 kg, which can shorten the fattening period by 20~50 days. In spring and autumn of each year, pigs should be injected with "triple vaccine" on time, which can effectively control swine fever, swine erysipelas and pig lung disease, reduce mortality and relatively reduce feed consumption.

After 60 days of age, piglets should be raised in pens with 2~3 pigs in each pen to avoid energy consumption in outdoor play. During the first 80 days of pregnancy and gestation, sows can be fed mainly green feed, high-quality coarse feed and dreg feed, with only about 1 kg concentrate per day. During the first month of labor, feed 2 - 3 kg concentrate per day. In this way, it not only ensures the normal development of the fetus, but also saves 60~90 kg of concentrated feed for each pregnant sow.

Early castration, early breeding boar 30 days old, gilt 40 days old castration, respectively, than people used to 60 days old castration weight gain of about 15%, and wound healing faster. Weaning piglets from 60 days to 40~45 days earlier can promote sow early estrus, early mating, shorten empty gestation period and save feed relatively.

The first deworming was carried out at the age of 60 days, and then every 2~3 months. According to the pig per kilogram weight with anti-worm allergy or deworming net 15~20 mg, once mixed feed feeding, drive out parasites in the body. If there are pig lice, use 0.1 kg of salt, 10 ml of kerosene, 20 ml of warm water to mix evenly and smear on the pig body surface to kill insects. At the same time, each pig is dissolved with 1 kg of quicklime in 5 kg of water, and the above clear liquid is mixed with feed and fed twice a day for 2~3 days to wash stomach and eliminate various parasites in the body. A week later, according to the pig weight per kilogram with rhubarb soda tablets 1 (up to 15 tablets) ground fine, divided into 3 times mixed feed stomach. In this way, each pig can gain 10 to 15 kilograms and shorten the fattening period by 25 to 40 days.

One is to insist on raising crossbred pigs. Crossbred pigs have strong vitality, rapid growth and good feeding effect. We should popularize the new technology of "three modernizations" of boar breeding, sow localization and piglet crossbreeding. Second, insist on feeding compound feed. According to the nutritional needs of pigs in different growth stages, we should insist on using complete compound feed, which has comprehensive nutrition and no waste, and has low feed and meat ratio. Third, protective feeding. In summer and autumn, gourd, melon, sunflower and other plants can be planted outside the pigsty to shade and cool down. In winter, plastic greenhouse feeding technology should be promoted, and insect repellent and immune injection should be done regularly. Fourth, change the hanger fattening to straight fattening. The traditional fattening method divides the fattening period of pigs into several stages, and uses concentrate and coarse feed to fatten pigs according to different stages. This method feed is single, nutrition is not comprehensive, can not meet the growth needs of pigs, pigs grow slowly, feeding cycle is long, low slaughter rate. If the method of raising nutrition level is adopted to fatten pigs from weaning to slaughter, the fattening period can be shortened effectively, the slaughter rate can be improved and the economic benefit can be increased. Fifth, supply sufficient clean water. Lack of water can affect pig appetite, digestion and normal growth, thereby reducing the utilization of feed.
