Scientific pig raising "six persistence"

First, insist on breeding hybrid pigs. With breeder boars such as Duroc, Pietrain, Decca, Landrace and other boars, piglets produced with local breeder sows are called hybrid pigs. Hybrid pigs have strong viability, rapid growth, and good feeding effect. Therefore, it is necessary to universally popularize the “three-ization” new technology of improved boar breeding, localization of sows, and hybridization of piglets. Second, adhere to the implementation of protective feeding. In the summer and autumn season, plants such as gourds, pumpkins, and sunflowers can be planted outside the pig house to cool down. In winter, plastic greenhouses are used to raise new technologies, and insecticide and immunization are regularly performed. Third, adhere to the self-cultivation and self-sustaining law. The breeding of good male and female sows, the breeding of their own hybrid piglets, and their own breeding of commercial pigs are conducive to disease prevention and disease prevention, raising the survival rate of piglets and reducing the cost of raising pigs. Fourth, adhere to the implementation of high-density pigs. In the winter of 0.8 square meters, pigs are reared with 1 finishing pig, and 1 square meter in the summer raises 1 finishing pig. As pigs are kept intensively, provincial pig houses have low investment in fixed assets, and fattening pigs compete for food and eating. The venues are small. When they are full, they sleep, the weight gains quickly, and the feeding period is shortened. Fifth, insist on science and technology to benefit. Promote one-stop rapid pig raising. The implementation of "five reforms and one plus," that is a change in the type of fat-raising pigs for Changqingbai, York, Duroc and other lean-type pigs. The second feed is to feed a single feed for the full price feed. Third, change the feed clinker wet feed for raw materials. Four to hang the shelf fattening as a straight fattening. Adopting a straight-line fattening method on weaned piglets can effectively shorten the fattening period, increase the rate of fattening, and increase economic efficiency. Fifth, change the disease to find a veterinarian for the prevention of disease-free early, strict control of swine fever, swine erysipelas, swine plague, paratyphoid fever four infectious diseases to reduce mortality, improve survival rate, slaughter rate. One plus is added with additives and auxin. 6. Adhere to timely slaughter and slaughter. After the fattening pigs weighed more than 90 kg, the daily weight gain was slowed down, and fat deposition was the main factor. Therefore, the more expensive it was, the more it was fed, and the more the fat was, the better it was. Less than 90 kilograms, although the feed utilization rate is high, but because of the small body weight and low meat rate, economically uneconomical, general finishing pigs with a weight of 90 to 120 kilograms slaughter the most appropriate.
