At present, the cost of feed for pig breeding is constantly increasing, and the scientific use of whether feed is maximized is an important issue for farmers. In this regard, the experts gave seven suggestions to help farmers breed efficiently.
1. Do not feed alone . Pure corn is used to feed pigs and consumes 6 kilograms of corn for every kilogram of weight gain. Feeding pigs with compound feed requires only 2.5 kg - 3 kg.
2. Feed after saccharification. After mashing corn flour, some starch can be converted into sugar, which can make pigs eat fast. The method is: put the corn flour into the tank, then pour 2 times of hot water to make a paste, and sprinkle 5 cm thick dry powder on the surface, and saccharify after 3-4 hours.
3. The crude protein content is low and the quality is poor, which cannot fully meet the growth needs of pigs . 15% bean cake or rapeseed cake can be added to the diet. For example, piglets should be added 5% fish meal.
4. Supply minerals. The content of mineral elements in corn is low, so bone minerals, calcium hydrogen phosphate and trace elements such as selenium, iron, copper, zinc and manganese should be added to the diet.
5. Supply vitamins. Corn has low vitamin content. When feeding, it must be fed with green and green feed, which can add multivitamins to livestock and poultry.
6. Do not store for a long time after crushing. The corn should be smashed and fed, and the crushed corn noodles are prone to deterioration over time. The amount of pulverization should be used up to 15 days, and it should be used up in 10 days in summer.
7. Soak before feeding. Corn is soaked to absorb water and expand and soften. Pigs are easy to chew and easy to digest and absorb. The soaking method is to soak the corn flour with 1-1.5 times of water for 2 hours.
