1. Calcium formate fertilization Adding 1.5 grams of calcium formate to piglets during the first few weeks after weaning can increase the growth rate of piglets by more than 12%, increase feed conversion by 4%, and reduce the incidence of piglets.
2. Make the sows more productive than the piglet. From the third day of weaning, add 200 mg of vitamin E and 400 mg of carrots to the sow and reduce the amount of these two additives to 50 when the sow is estrus. %, feed until 21 days after pregnancy. Using this method, the sow's litter size can be increased by 21.9%, and the sows and piglets are strong in physique and the survival rate of piglets is high.

4. Feeding copper weight gain Adding trace element copper in pig fattening period can significantly increase the weight of the pig, and inhibit certain bacteria from invading the pig, ensuring the pig's healthy growth. In the feed with added antibiotics, if you add appropriate amounts of copper, you can increase the pig's daily gain by 6.7%, and feed utilization by 2% to 5%.
5. Feeding saccharin weight gain with a proper amount of saccharin to increase pig weight gain. The method is: add 0.05 grams of saccharin per kilogram of compound feed. When saccharin is dissolved in water and mixed in the material, the feed intake of the pig can be increased, and the daily weight gain can be increased by 7%. For every hundred kilograms of pigs gained weight, feed consumption and costs dropped by 4.8% and 3.5%, respectively.
6. Feeding of yellow fungicide: When the pig grows to 35 kilograms, yellow pigment is added to the feed. The pig's daily weight gain can be increased by 7%, the feed conversion rate can be increased by 5%, and the amount of flavomycin added: Piglets Add 20 mg per kilogram of feed, finishing pigs add 50 mg per kg of basal diet, 250 mg per kg of mineral feed.
7. Feeding Citric Acid Gain Weight Adding citric acid to pig feed can increase the palatability of the feed, improve the ability of the pig to digest and absorb nutrients, and increase the feed conversion rate. Adding 30 grams of citric acid per kilogram of feed can increase pigs from 189 grams per day to 216 grams. This method is best for feeding weaned pigs weighing between 5 and 10 kilograms.
8, to the pig "moving" fattening pigs to change the ring, pigs can increase appetite, more phlegm, growth accelerated. However, changing the circle should not be too busy.

Pigs in each group should not be exchanged or mixed with new pigs, otherwise the pigs will feel uneasy and even bite each other.
9. Feeding oxygenated soft drinks to feed weaned piglets with oxygenated soft drinks, giving the weaned pigs once every 5 days, and gaining 200-250 grams per day. One of the oxygenated soft drinks is to add a certain proportion of oxygen to ordinary drinking water, usually 1 liter of oxygen in 1 liter of water. If you can add some additives such as fertilizers in soft drinks, the effect is better.
10, feeding vitamin C to improve semen quality in the boar's feed, daily add 1 to 4 grams of vitamin C, semen quality can significantly improve the boar. In addition, adding 1 gram of vitamin C per day to the sow diet one week prior to delivery can significantly reduce piglet umbilical cord bleeding and piglet mortality.
