He has made outstanding contributions in pig breeding, pig industrialization and talent training, and has won 9 provincial and ministerial science and technology awards and 2 national patents. Author of the book "Breeding Pigs in China", he proposed the theory of matching line breeding, bred Gansu white pigs and three new specialized lean pig lines to match the Walter pig series, and formulated the "Local Standard for Walter Pig Matching Lines" ", created the "Xinhua Model" of "factory farmers", built 44 10,000-head factory pig-raising enterprises in the five northwest provinces, and promoted the supporting technologies of factory pig-raising engineering to the whole country. During the "Eighth Five-Year Plan" period, he presided over the breeding of three new "specialized" lean pig lines, completing the task of building an improved breeding system for Gansu's pig industry. He presided over the breeding of a new breed of "Walter Pig Matching Line". At that time, the quality was superior to foreign breeds. He formulated the "Local Standard for Walter Pig Matching Line" and solved the problem of breed standardization. "Walter Pig Matching Line" is one of the livestock and poultry varieties recognized by the Ministry of Agriculture to be promoted nationwide during the "Tenth Five-Year Plan" period; during the "Ninth Five-Year Plan" period, the company presided over the completion of the "Supporting Breeding of Synthetic Line Hybrid Pigs" research plan project. The breeding and promotion of these excellent varieties not only improve the quality of pork, but also save a lot of costs for introducing varieties from abroad.
Liu Mengzhou also pays attention to the application, promotion and industrialization of the results. He presided over the research and development of supporting technologies for factory pig raising engineering, among which the "new factory pig house" and "sow farrowing bed" adapted to factory pig raising have applied for national patents (the application number has been disclosed); he proposed The new pig industrialization model of "five unified points" includes "factory breeding, household fattening, unified seed supply, unified feeding standards, unified epidemic prevention and eradication, unified technical procedures, unified organization of sales and dispersed fattening by farmers". At the same time, it will The factory pig-raising engineering technology has been promoted and applied to 44 10,000-head factory pig-raising enterprises in five provinces and regions in northwest China. In the past three years, a total of 1.3042 million pig breeds have been promoted, with an increase of 139 million yuan in profits and taxes. The application and promotion of this achievement has promoted the process of factory pig farming and intensive production in our province, increased farmers' income, and provided experience for modern pig farming.
He has presided over and participated in the completion of a number of research results, and published 14 papers in China. "Factory Pig Raising Engineering Technology" has twice conducted academic exchanges at national professional societies; as deputy editor-in-chief The book "Cultivation of Pig Breeds in China" co-edited has played a major role in promoting the development of factory pig production across the country.
