The world's first "digital pig data set" was born in Chongqing

Introduction: the "Second China animal husbandry science and Technology Forum" held in Rongchang County, Chongqing recently announced that the "digital pig data set" which was completed by Chongqing Animal Husbandry Research Institute, the Third Military Medical University and Chongqing Institute of technology was born in Chongqing It is the first set of pig digital visualization data set in the world and has full independent intellectual property rights in China The pig samples selected in this data set are Rongchang pig, a famous local pig species in the world This pig is a sows, 5 months old, 45 kg, 44 cm high, 94 cm long, strong, normal growth and development, no organic trauma The data set is sliced by high-precision CNC milling machine in a special low-temperature laboratory and photographed by high-precision digital camera The image quality is high and the internal structure display effect is good There are 2315 continuous section images in this data set, and the total data volume of the whole data set is 145.6gb As like as two peas of China, Chen Jianhua, Secretary General of the Chinese agricultural society, said that this set of data is the first step in the research of the "digital pig" The second step is to divide every piece of data into organs or tissues, and then reconstruct a computer to produce a pig that is exactly the same as a real pig Through this visible pig, not only can we have a more comprehensive and in-depth understanding of the structure of the pig, and on this basis, we can develop auxiliary teaching and training software On the one hand, it can significantly improve the quality of teaching, reduce the experimental funds, on the other hand, it can promote the improvement of pig raising skills of farmers and farmers, and improve the efficiency of pig raising The third step is to build a physical and physiological model by digitizing the past, present and future pig breeding research data and research results, superimposing on the digital visible pig model, so as to gradually improve the "virtual pig" and finally form a "digital pig platform" On this platform, various virtual experiments can be carried out, such as growth and development, genetic breeding, nutrition needs experiment, feeding experiment, drug experiment, metabolism experiment, etc., and different experimental schemes can be optimized in advance In this way, not only the experimental scale and time can be greatly reduced, but also the experimental cost can be greatly increased Zhang Shaoxiang, a professor of the Third Military Medical University who participated in the research, said that using digital technology to reshape modern pig industry will fundamentally improve the level of pig technology in China, change the backward face of traditional pig industry in China, effectively promote the transformation of the growth mode of pig industry, and promote the development of pig breeding and even the whole animal husbandry production.
