Improve the level of epidemic prevention and control work
Epidemic diseases are the number one factor affecting the healthy development of the pig industry, and epidemic prevention and control work must not be relaxed at all times. Focus on the prevention and control of African swine fever and improve and implement normalized biosecurity management measures. Carry out epidemic isolation, elimination, epidemic monitoring and vaccine immunization.
Improve the production level of breeding pig groups
First, we must optimize the group structure of breeding sows such as breed and fetal age, accelerate the elimination of old and low-yielding sows, and ensure the maximum production efficiency of breeding pigs. The size of the sow group can be appropriately reduced based on the current industry's breeding sow stock and its own conditions. Second, to make full use of hybrid advantages, a three-way hybrid production system should be adopted as much as possible. Compared with purebred pig production, the reproductive performance of three-way hybrids can obtain more than 15% of hybrid advantages. Third, it is necessary to strengthen the breeding of gilts and complete the screening of gilts before 120 days of age; after the first estrus period of 150 days, switch from free feeding to controlled feeding to effectively control back fat and body weight.
Reduce feed costs
To change the erroneous concept that the higher the protein level of pig feeds, the better, the research results and practical proof of pig dynamic nutritional needs and precise nutrition supply technology can be achieved by rationally setting the net energy level of the diet and adding low-protein daily diets using industrially synthesized amino acids to the feed. Grain technology can effectively supplement short amino acids in raw materials, reduce the amount of protein in feed, and improve feed protein utilization efficiency. Secondly, according to the different physiological stages of pigs, the implementation of staged feeding technology can not only ensure the full absorption and utilization of nutrients in the feed and the healthy and rapid growth of pigs, but also protect the intestinal health of pigs and reduce nitrogen and carbon waste emissions.
