Baking soda for weight gain: In the United States, baking soda is added to pig feed deficient in lysine to make up for the lysine shortage. This method helps with the digestion and absorption of crude fiber, so pigs put on more meat and gain weight faster.
Copper for weight gain: In Japan, adding an appropriate amount of copper to feed already mixed with antibiotics can increase the daily weight gain of pigs by 6.7%, raise feed utilization by 2-5%, and inhibit the attack of certain pathogens on pigs, ensuring healthy growth.
Citric acid for weight gain: In the United Kingdom, adding 30 grams of citric acid per kilogram of feed improves the palatability of the feed, enhances the pigs' ability to digest and absorb nutrients, and raises the feed conversion rate, increasing daily weight gain from 189 grams to 216 grams. This method is best suited to feeding weaned pigs weighing 5-10 kg.
Calcium formate for fattening: In Finland, adding 1.54 grams of calcium formate to the feed during the first few weeks after piglets are weaned increased the piglets' growth rate by more than 12%, raised the feed conversion rate by 4%, and reduced the incidence of disease among piglets.
"Moving house" for fattening: In the United States, changing pens for fattening pigs can increase their appetite and speed up growth. Pens should not be changed too frequently; once a month is appropriate, and the pens should be basically the same in size and form. Do not arbitrarily swap pigs between groups or mix in new pigs, otherwise the group will become restless and may even bite one another's heads.

High protein for weight gain: In the United Kingdom, starting 2 weeks before farrowing, sows are fed high-protein feed containing more than 18% crude protein until weaning; after weaning they are switched to ordinary low-protein feed. This not only markedly increases the piglets' birth weight and weaning weight and reduces the disease rate, but also shortens the sow's farrowing cycle and raises the conception rate and the number of piglets born.
Vitamin C for better breeding: In Germany, adding 1-4 grams of vitamin C daily to boars' feed can improve semen quality. In the United States, adding 1 gram of vitamin to the diet of sows one week before farrowing can greatly reduce umbilical bleeding in piglets and piglet mortality.
Method for sows to produce more piglets: In Germany, starting on the third day after the piglets are weaned, 200 grams of vitamin E and 400 grams of carrots are added to the sow's feed; when the sow comes into estrus, the amounts of these two additives are reduced by 50%, and feeding continues until 21 days after conception. Using this feeding method can increase the number of piglets born per litter by 21.9%, and the sows and piglets are strong in constitution, while the piglet survival rate also rises.
