1. Adding 1.5g calcium formate to the feed in the first few weeks after weaning can increase the growth rate of piglets by more than 12%, increase the feed conversion rate by 4% and reduce the morbidity of piglets.

2. Feeding method to improve the litter size of sows: from the third day of weaning, add 200 mg of vitamin E and 400 mg of carrot to sows, and when sows are in estrus, the dosage of these two additives will be reduced by 50% until 265,438+0 days after pregnancy. By adopting this method, the litter size of sows can be increased by 2 1.9%, sows and piglets are physically strong, and the survival rate of piglets is high.

3. Feeding baking soda to gain weight Adding baking soda to lysine-deficient pig feed can make up for the lack of lysine, which is beneficial to the digestion and absorption of crude fiber, so that pigs can gain more meat and gain weight quickly.

4. Feeding copper to gain weight Adding trace element copper during the fattening period of pigs can obviously increase the weight of pigs, inhibit the invasion of some germs on pigs and ensure the healthy growth of pigs. If proper copper is added to the feed mixed with antibiotics, the daily gain of pigs can be increased by 6.7%, and the feed utilization rate can be increased by 2% ~ 5%.

5. Feeding saccharin to gain weight It is good to feed pigs with proper amount of saccharin to gain weight. The method is as follows: adding 0.05g saccharin to each kilogram of compound feed, dissolving saccharin in water and mixing it into the feed can improve the feed intake of pigs and increase the daily gain by 7%. The consumption and cost of pig feed per 100 kg decreased by 4.8% and 3.5% respectively.

6. When the pig grows to 35 kg, the daily gain of the pig can be increased by 7%, and the feed conversion rate can be increased by 5%. The amount of flavomycin added: 20 mg per kg feed for piglets, 50 mg per kg basic diet for finishing pigs and 250 mg per kg mineral feed.

7. Feeding citric acid to gain weight Adding citric acid to pig feed can increase the palatability of feed, improve the digestion and absorption capacity of pigs for nutrients, and improve the feed conversion rate. Adding 30 grams of citric acid to each kilogram of feed can increase the daily gain of pigs from 189 grams to 2 16 grams. This method is most suitable for feeding 5 kg ~ 10 kg weaned piglets.

8. "Moving" pigs to fatten, changing circles for fattening pigs, can make pigs increase their appetite, gain more weight and accelerate their growth. However, it is not advisable to change the circle too frequently. It is advisable to change the circle once a month. The size and shape of the circle should be basically the same. Each group of pigs should not be changed or mixed with new pigs at will, otherwise the pigs will feel uneasy and even bite each other.

9. Feed oxygenated soda water to gain weight. Feed the weaned piglets with oxygen-containing soda water every 5 days 1 time, and the piglets gain 200 ~ 250g daily. Among them, oxygen-containing soft drinks are made by adding a certain proportion of oxygen to ordinary drinking water, usually by injecting 1 liter of oxygen into 1 liter of water. If some additives such as fattening agent can be added to soda, the effect will be better.

10. Feeding vitamin C improves semen quality. Adding 1 ~ 4g vitamin C daily to boar feed can obviously improve boar semen quality. In addition, adding 1g vitamin C to sow diet one week before labor can greatly reduce umbilical cord bleeding and piglet mortality.
