Now pig farms have pig raising equipment to assist in raising pigs, so we should be more efficient in raising pigs and not waste resources in vain. Here are four efficient ways to raise pigs.
1、 Self feed, reduce cost. Feed cost accounts for 70% of the cost of pig raising, so reducing feed cost is very important for pig raising. First, it is necessary to reduce the loss and waste of feed processing, preservation and feeding environment, prevent mildew deterioration and rodent damage collapse, and use ecological rodenticide to kill rats. Second, adhere to self feed. The cost of raising pigs can be greatly reduced by using self-produced or external enough corn (2428, - 1.00, - 0.04%) and proper combination of cake, rice bran and wheat bran, and making full use of all kinds of dregs, forage and green roughage. The third is to add additives for pigs, so as to solve the problem of reducing the nutritional level after adding green roughage and promote normal marketing.
2、 Do a good job in deworming and improve efficiency. At the beginning and the middle of fattening, insect repellents should be used to drive away the parasites inside and outside the pig body, which can be 10-20 days ahead of schedule. Each pig can save 20 kg of feed and increase the efficiency by 30 yuan.
3、 Do a good job in disease prevention and control, regular immunization injection, and control the occurrence of the disease.
4、 Self breeding, stable pig source. Fattening farms and households should raise a certain number of sows for self breeding. When the price of piglets rises, the sows can be sold for profit. When the price of piglets is low, the fattening pigs can make money. The risk of raising sows is very small. Therefore, no matter how the pig market changes, it is necessary to keep a good sow to stabilize the pig source. Otherwise, the price of piglets will rise, and the current sows will not be nearly thirsty after hydrolysis. It is too late.
