Want to sell pork at a good price? As an example for you, the China Agricultural Technology Network may choose to provide pigs for professional households to choose from or try the following methods:
Feeding copper
Adding trace element copper during the fattening stage of pigs can significantly increase the weight of the pigs, and inhibit the infestation of certain pathogens to the pigs to ensure the healthy growth of the pigs. 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%.
Give the pig "moving"
Tests have shown that changing pigs for finishing pigs can increase pig appetite, increase appetite, and accelerate growth. However, changing the circle should not be too busy. It is advisable to use it once a month. The size and form of the circle must be basically the same. Pigs in each group should not be exchanged or mixed with new pigs, otherwise the pigs will feel uneasy and even bite each other. Feeding vitamins From the third day of weaning on piglets, adding 200 mg of vitamin E and 400 g of carrots when feeding sows, and reducing the amount of these two additives by 50% to the sows when they are estrus, feeding them to 21 days after pregnancy until. 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 piglets have a high survival rate.Feeding baking soda
Adding baking soda to a pig feed lacking lysine can compensate for the deficiency of lysine and facilitate the digestion and absorption of crude fiber, so that the pig grows more meat and has faster weight gain.
Feeding sweetener
Feeding pigs with moderate amounts of saccharin has a good effect on weight gain. The method is: add 0.05g saccharin per kilogram of compound feed. When saccharin is dissolved in water and mixed in the feed, the feed intake of the pig can be increased, and the daily gain can be increased by 7%. For every hundred kilograms of pigs weight gain, feed consumption and costs dropped by 4.8% and 3.5% respectively.
Feeding citric acid
Adding citric acid to the 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 increased the pig's daily gain from 189 grams to 216 grams. This method is best for feeding weaned pigs weighing 5 to 10 kg.
Feed calcium formate
Adding 1.5 grams of calcium formate to the feed 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.
Feeding oxygenated soda
Weaned piglets were fed with oxygenated soft drinks and the weaned piglets were fed once every 5 days. The piglets could gain 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 detergent in soft drinks, the effect is better.
