First, the brush body fattening every morning and evening to the finishing pig brushing the pig body (brushing with a hard brush body) 1 time, each time 10-20 minutes. In the case of the same feeding and management conditions, pig weight gain can be increased by 7.2% - 11.4%. Second, pig blood fattening to collect healthy (or slaughter) pig fresh blood, add 5 ml of anticoagulant (sodium citrate) per 100 ml, and store at 2-10 °C for use. Every 2 days, every 2 kilograms of body weight per blood transfusion 2 ml, regular quantitative input into the veins of fattening pigs, can accelerate the growth and development of pigs. This method is particularly effective for shelf pigs that have poor nutritional conditions and become stiff pigs. Third, glutinous powder fattening Generally, pigs weighing less than 25 kg are fed 10 g per day, 25 kg for pigs over 25 kg, and 50 kg for pigs over 50 kg. Fourth, egg white fattening in the neck of the pig under the weight of 50 kg or more on both sides of the thyroid or submandibular gland (incubation point) each injection of 5-10 ml fresh egg white, injection needle vertical 3.3 cm, the pig loves to sleep after the injection Love moves, indicating that the injection is successful, and the injection is repeated once every 5-7 days, and the dose is doubled. Then feed the digestible, nutrient-rich feed and care for 0.5-1 months. On average, the pigs can increase the weight by more than 0.5 kg on the basis of normal weight gain. 5. Lysine Fertilizer Adding 1-3 kg of lysine to pigs per ton of feed can increase the daily weight gain of pigs by 15%-25%, and reduce feed consumption by 15%-20%. 6. Fermented blood meal and fattening 3%-10% fermented blood meal is added to the pig's diet. Generally, the pigs weighing 25 kg can be slaughtered for 75 days, the weight is over 100 kg, and the feed cost is reduced by about 20%. Seven, humic acid fertilizer to promote more than 50 kg of pigs, daily feeding 5 grams of humic acid, divided into early and late 2 times feeding, even feeding 20-30 days, each day can increase the weight of 120- 200 grams, shortening the time of the release.
