In the direct cost of pig production, feed accounts for about 70%. Under the situation that the feed price continues to rise, how to meet the nutritional requirements of the body and save the feed to increase income is becoming more and more important. The following is a brief introduction to several methods for raising pigs and materials: selecting piglets
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. Feeding
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.
Timely 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 wounds heal faster, can shorten the fattening period of about 20 days, saving about 20% of feed.
Timely deworming and 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. The above 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, take 1 piece of rhubarb soda tablets (maximum of 15 pieces) per kilogram of body weight, and mix the ingredients in 3 times. In this way, each pig can gain 10 to 15 kilograms of weight and shorten the fattening period by 25 to 40 days.
Scientific feeding
According to the growth and development rules of slow growth, medium-term growth and slow growth in the early stage of pigs, in order to obtain higher feed compensation, straight-line fattening should be adopted to shorten the feeding cycle and save feed. At the same time, it is necessary to carry out fine, green and coarse feed mix, and carry out raw feeding and feeding; in feeding times, adopt two-day feeding system to reduce energy consumption and feed due to multiple feeding stimulation of pig movement. Loss of throwing and reducing feed utilization.
Segmented feeding
The sow empty stage 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. Timely 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.
prevent epidemics
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. Timely
When the weight of the pig is 20-90 kg, the daily gain increases linearly. After 100 kg, the growth is slow, and the daily weight gain gradually decreases. Therefore, when the pig is raised to about 90 kg, it is good.
