Methods for Breeding Introduced Pig Breeds and Key Points for Applying New Breeding Technologies
The continuous development and progress of science and technology have made it possible for people to explore natural laws and reveal biodiversity. The greatest advancement in pig breeding in the 20th century was breaking through 800 g/day in daily weight gain, achieving a lean meat rate of over 60%, a feed-to-meat ratio of 2.8:1, and slaughter pigs reaching over 90 kg body weight at 156 days, producing truly lean pigs. In recent years, with the continuous development of breeding theory and practice, pig breeding in countries with developed pig industries has gradually transitioned from breed selection to specialized composite line breeding, targeting different uses of each line in the crossbreeding system

Applying nitrogen fertilizer properly to effectively prevent and control plant pests and diseases
Nitrogen fertilizer is one of the fertilizers we use more commonly. In fact, many studies and practices have shown that rational fertilization can prevent and control crop pests and diseases. In the process of fertilizing, it is possible both to apply fertilizer and to avoid polluting the environment, so it can be said to achieve multiple benefits at once. So how exactly can nitrogen fertilizer be used to prevent and control plant pests and diseases?
