TAILIEUCHUNG - The population structure, production and management of co swine breed in Nghe An province, Vietnam
This descriptive-evaluative study was undertaken in order to evaluate the current condition of the Co pig population in Nghe An province, Vietnam in terms of size, structure and effective size. It was conducted from September, 2011 to January, 2012. Based on its current population structure, the Co pig can be classified as a rare breed and even though the effective population size is less than 500. Most of the Co pig raisers are smallholders with insufficient capital and inadequate technical knowledge to expand their operation and the production efficiency. | Nguyễn Hưng Quang và Đtg Tạp chí KHOA HỌC & CÔNG NGHỆ 107(07): 37 - 43 THE POPULATION STRUCTURE, PRODUCTION AND MANAGEMENT OF CO SWINE BREED IN NGHE AN PROVINCE, VIETNAM Nguyen Hung Quang1*, Bui Ngoc Son2, Agatep2 2 1 College of Agriculture and Forestry - TNU Laguna State Polytechnic University, Siniloan, Laguna SUMMARY This descriptive-evaluative study was undertaken in order to evaluate the current condition of the Co pig population in Nghe An province, Vietnam in terms of size, structure and effective size. It was conducted from September, 2011 to January, 2012. Based on its current population structure, the Co pig can be classified as a rare breed and even though the effective population size is less than 500. Most of the Co pig raisers are smallholders with insufficient capital and inadequate technical knowledge to expand their operation and the production efficiency. Co pigs had good adaptability and high resistance against diseases. In consideration of the significant contribution of the Co pig, the government should spearhead measures so that the pig breed will be conserved and further developed through the development and application of appropriate technologies related to pig breeding, nutrition and health management. Key words: Co pig, Nghe An, Vietnam, Production, Reproduction INTRODUCTION* Pig production is mainly conducted by smallholders in Vietnam (Singh, 1996). In smallholder farms, availability of local feed resources used for pigs is unstable and unbalanced throughout the year (Hai and Pryor, 1996). At present, exotic and crossbred pigs dominate, while local pigs make up only 26% of the national pig herd, mostly in uplands, rural and remote areas. The decentralized structure of the Vietnamese breeding system, the less developed central coordination and the common use of Artificial Insemination have all supported the spread of exotic pigs in Vietnam, especially at the smallholder level which makes up 80 to 95% of Vietnamese .
