Wuhan Institute of Technology is the first university in the country to set up animal nutrition and feed processing, and its animal science major belongs to national specialty. Professor Hou Yongqing of the school insisted on the research of animal nutrition and feed science in the past 23 years, and has an important influence in the field of pig nutrition and green feed additives.

In 2010, Professor Hou Yongqing, as the main accomplisher, won the second prize of National Science and Technology Progress Award for the key technology of piglet intestinal health regulation and its application in feed industrialization. Through the innovation of theory and method, the project developed key technologies for piglet intestinal health regulation and provided technical support for the healthy and sustainable development of pig industry in China.

On June 15, 2012, we interviewed Professor Hou Yongqing. CWP China Feed Industry Information Network - based on feed, serving animal husbandry

Professor Hou Yongqing said that China is the world's largest pig-raising country, and the pig industry has become an important industry related to the national economy and people's livelihood. Feeding piglets is the key to raising pigs. However, due to the relative delay in piglet feed development, the annual economic losses caused by poor growth and health of piglets in China are as high as 30 billion yuan. The piglet feed market has long been monopolized by foreign-funded enterprises, which seriously hinders China. The development of the pig industry.

Professor Hou Yongqing conducted an in-depth study on the theoretical issues related to piglet nutrition and intestinal health. It was found that malnutrition, physiological disorders, pathogenic microorganisms and other factors can cause disorders in the intestinal structure and function of piglets, leading to indigestion and diarrhea. Growth retardation, and even death, especially the poor intestinal health caused by weaning stress, has become an urgent problem in piglet breeding.

Professor Hou Yongqing and related research institutes and enterprises have jointly identified the key mechanisms affecting the healthy nutrition and regulation of piglets' intestines, established key technologies for nutrition regulation, and developed a series of high-quality piglet feed products for suckling pigs. Sexually solved the problem of diarrhea, low feed intake and growth retardation after weaning. Compared with traditional feed, piglets using the feed material increased their daily gain by 20%, feed utilization by 15%, diarrhea rate by 35%, and survival rate by 5%, which greatly improved pig production efficiency.

Since 2004, the results have been directly applied in nearly 100 enterprises in 30 provinces and cities in China. In recent years, the company has promoted 3 million tons of suckling pig feed, increased profits by more than 2 billion yuan, and added taxes of 800 million yuan. It has promoted the development of large-scale key enterprises including five listed companies. CWP China Feed Industry Information Network - based on feed, serving animal husbandry

Professor Hou Yongqing also actively explored the development of new green feed additives. CWP China Feed Industry Information Network - based on feed, serving animal husbandry

The so-called green feed additive refers to a general term for feed additives that can promote the growth and health of livestock and poultry, improve the quality and quality of products, and have no residue in livestock and poultry products and no pollution to the environment. It mainly includes probiotics, enzyme preparations, acidifiers, oligosaccharides and plant extracts. CWP China Feed Industry Information Network - based on feed, serving animal husbandry

He said that the use of feed or its additives is not standardized, and the long-term application of antibiotics in feeds will allow toxic and harmful substances to remain in pigs and their products, while large and large-scale use of high-copper, high-zinc and organic arsenic additives, It also causes pollution to the surrounding environment, affects the normal growth of crops, and even endangers human health.

Since 1999, Professor Hou Yongqing has been researching green additives for piglet feed, and has developed “plant extract feed additives” and “biotic feed additives”, which can effectively replace the use of antibiotics, inhibit the breeding of harmful bacteria such as Escherichia coli and Salmonella, and promote intestinal probiotics. The bacteria grow, maintain the intestinal micro-ecological balance, and reduce the incidence of disease. And the production standards have been formulated, and a number of brand products have been formed, which are sold well in 11 provinces and cities nationwide, and the market effect is well reflected. Wuhan Fanhua Biotechnology Co., Ltd. has used this technology to produce feed since 2002, with an annual output value of 30 million yuan.

The achievement of the "Key Techniques for Nutritional Regulation and Feed Industrialization of Piglets" was awarded the first prize of Science and Technology Progress Award of Hubei Province in 2011. It has been promoted and applied in Hubei, Hunan, Yunnan and other provinces and cities, and has spread to 11 provinces and cities nationwide through technology application units, with significant economic and social benefits, and promoted the development of piglet feed industry and pig industry.

In addition to piglet feed, Professor Hou Yongqing also conducts research on aquafeeds. CWP China Feed Industry Information Network - based on feed, serving animal husbandry

China is the world's largest aquaculture country. In the past, most farmers used single feed materials or simple mixed feeds. Although the cost was cheap, the nutrition was not comprehensive and the feed was wasted. Not only did it not achieve good economic benefits, but also easily polluted the water source.

Professor Hou Yongqing has been continuously researching aquatic feed since 1987. He has published three monographs and provided technical services to more than 20 companies, making great contributions to the development of aquatic feed in Hubei. Under his impetus, Wuhan Institute of Technology cooperated with Hunan Tangrenshen Group to establish the Aquatic Animal Nutrition Research Center. In 2005, with the help of Professor Hou Yongqing, the Tangren God Group developed the “Xiangda” brand fish feed. The feed gave the Tangrens Group a production value of 1 billion yuan.
