Pick a trick
Large-scale pig raising must be selected as "three yuan" hybrid piglets, with long waist, wide chest, short mouth, full hips, full limbs, thick white, grazing food, about grams of pigs is best, only 160 days It can reach 90-100 kg from left to right, which can shorten the fattening period by 20 to 50 days.
Two-point captivity
After 60 days of age, piglets should be kept in circles, with 2 to 3 pigs per lap, so as not to be able to chase after running outdoors.
Three early castration
Small boars 30 days old and gilts 40 days old castrated, respectively, about 15% more weight than the customary 60-day castration, and the wound healed faster.
Four healthy stomach
When the piglets are 60 days old, the first insects are driven. After every 2 to 3 months, the insects are dewormed once. According to the pigs, the anti-creeping or deworming net is 15-20 mg per kilogram of body weight, and the mixture is fed once to remove the parasites. If you have piglets, you can use 10 grams of salt, 10 ml of kerosene, and 20 ml of warm water to spread on the pig body to kill insects. At the same time of deworming, each pig is dissolved in 5 kg of water with 1 kg of quicklime, and the above-mentioned clear liquid mixture is fed twice a day, and the stomach is washed for 2 to 3 days to remove various pests in the body. One week later, according to the pig per kilogram of body weight, use one piece of rhubarb soda tablets (maximum of 15 pieces) to finely grind and apply the mixture to the stomach for 3 times.
In this way, each pig can gain 10 to 15 kg and shorten the fattening period by 25 to 40 days. The staged sows and the first 80 days of pregnancy can be mainly used for green fodder, high-quality roughage and dregs, with only about 1 kg of concentrate per day. One to three kilograms of concentrate are fed daily 1 month before delivery. In this way, the normal development of the fetus is guaranteed, and the sow can save 60-90 kg of concentrate for every pregnancy.
Five early breeding
Weaning 60-day-old piglets early to 40 to 45 days, this can promote early estrus, early breeding, shortening the empty period, and relatively saving feed.
Six anti-epidemic diseases
In the spring and autumn of each year, the “triple seedlings†are injected on the pigs on time, which can effectively control the three major diseases of swine fever, pig erysipelas and swine plague, reduce the mortality rate and reduce the consumption.
