Research Progress of Disease Resistance breeding in Pigs
The goal of high yield usually leads to a decrease in pig resistance. At the same time, pig farm diseases, especially viral infectious diseases, are a serious threat to the health of pigs. Although vaccination played an important role in prevention and treatment, the epidemic of infectious diseases could not be completely controlled and eliminated. In the long run, using genetic methods to improve the resistance of pigs to pathogens, carrying out disease-resistant breeding has the effect of curing the root causes. In the 1930s, some scholars reported that there were differences in sensitivity to Marek's disease among different chicken breeds.

Application of phytase in diets of pigs and chickens
Phytic acid or phytate is common in plant feed, and most of the phosphorus exists in the form of phytate phosphorus. Phytic acid can form a stable complex with metal ions such as calcium ion, iron ion, zinc ion and copper ion, and can also combine with protein and starch, reducing the activities of endogenous amylase, protease and lipase. The digestibility of nutrients decreased significantly. Phytic acid is not absorbed by monogastric animals, and most of it is excreted in the form of feces, which not only greatly reduces the utilization rate of phosphorus, but also causes environmental pollution, especially water pollution.

Research Progress on Detection Technology of Porcine circovirus
Porcine circovirus disease is a kind of viral infectious disease caused by porcine circovirus (PCV) infection and characterized by immunosuppression. the clinical manifestation is mainly caused by postweaning multisystemic wasting syndrome of piglets caused by PCV-2. In this paper, the detection techniques of the virus at home and abroad in recent years, including virus isolation, electron microscopic observation, polymerase chain reaction, indirect immunofluorescence test, immunohistochemical technique, enzyme-linked immunosorbent assay, in situ nucleic acid hybridization test and so on. Porcine circovirus disease

Effect of nodule number of seed stem on the yield, growth and development of Polygonatum polygonatum
Effect of Node number of seed Stem on the yield, growth and Development of Polygonatum polygonatum in production, Polygonatum polygonatum is often propagated by rhizome, which is often called "seed stem" because its rhizome is beaded or nodular. The quality of seed stem directly affects seedling emergence and growth.
