家畜改良의 現況과 問題點

Present status and problems in genetic improvement of farm animals in Korea

Genetic improvement program for Korean Native Cattle is carried out at the Alpine Experiment Station and at Seosan Cattle Breeding Farm of National Livestock Cooperatives Federation(NLCF). Artificial insemination of dairy cattle is performed by the Animal Improvement Center of NLCF. To solve the problems in cattle improvement, it is desirable to establish uniform improvement program of cattle by the committee, to provide support for breeding researches and to conduct the performance test and progeny test more extensively. Central swine testing station was established in March, 1984 to select and distribute superior breeding stock. Swine improvement program is carried out by ceratin private swine breeding farms. To solve the problems in swine improvement, it is necessary to adopt the policy which will promote the development of superior swine breeding farms, to carry out effective on-farm testing of breeding stock and to provide government support for the Korea Swine Testing Station. During the period from 1965 to 1984, the egg production per hen in layers was improved from 195 to 255 and the average egg weight was increased from 56.6 gr. to 62 gr. In broilers, the average body weight at 8 weeks of age was increased from 1kg to 2.3kg during the period and the feed efficiency was improved from 3.0 to 2.15. To solve the problems in poultry improvement, it is necessary to adopt the policy which will promote the development of breeding programs for domestic stocks and to provide support for the Layer and Broiler Random Sample Test Station.
