There are new ways to fatten pigs.

Feed copper

The addition of trace element copper in the fattening period of pigs can significantly increase the body weight of pigs, inhibit the damage of some bacteria to pigs, and ensure the healthy growth of pigs. In the feed mixed with antibiotics, if an appropriate amount of copper is added, the daily gain of pigs can be increased by 6.7%, and the feed utilization rate can be increased by 2% and 5%.

Give the pig "move"

The experiment shows that changing circles for fattening pigs can increase their appetite, gain more fat and accelerate their growth. However, the lap change should not be too frequent, it is appropriate to change the circle once a month. The size and form of the circle should be basically the same. Each group of pigs should not be swapped or mixed with new pigs, otherwise the pigs will feel uneasy and even bite their heads.

Feed vitamins

From the third day of weaning, 200 mg of vitamin E and 400 g of carrots were added to the sows, and when the sows were in estrus, the amount of these two additives was reduced by 50% until 21 weeks after pregnancy. By using this method, the litter size of sows can be increased by 21.9%, and the physique of sows and piglets are strong, and the survival rate of piglets is high.

Hey, baking soda.

Adding baking soda to the feed of pigs lacking lysine can make up for the deficiency of lysine, and is beneficial to the digestion and absorption of crude fiber, so that pigs gain more weight and gain faster.

Feed saccharin

Feeding pigs with appropriate amount of saccharin has a good effect on weight gain. The method is: adding 0.05 grams of saccharin per kilogram of compound feed, dissolving saccharin in water and then mixing it into the feed, the feed intake of pigs can be increased, and the daily gain can be increased by 7%. For every hundred kilograms of wool pigs, feed consumption and cost decreased by 4.8% and 3.5%, respectively.

Feed citric acid

The addition of citric acid to pig feed can increase the palatability of feed, improve the ability of digestion and absorption of nutrients, and increase the conversion rate of feed. Adding 30 grams of citric acid per kilogram of feed can increase the daily gain of pigs from 189 grams to 216 grams. This method is most suitable for feeding weaned pigs weighing between 5kg and 10kg.

Feed calcium formate

Adding 1.5 grams of calcium formate to the feed of piglets 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 incidence of piglets.

Feed oxygenated soda

Weaned piglets were fed with oxygenated soda and drank once every 5 days. The daily weight gain of weaned piglets was 200,250g. Among them, oxygenated soda 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 an accelerant to the soda, the effect will be better. Song Liling
