한우의 주요 경제형질에 대한 유전모수 추정 1 . 체중 및 흉위에 대한 일반능력 및 자료의 분포 특성 = Estimation of Genetic Parameters for Economic Traits in Korean Native Cattle 1 . General performances and distribution property of data for body weights and chest girth

다국어 초록 (Multilingual Abstract)

This study was carried out to seek the effects of environmental factors and properties of growth as being based on genetic evaluation of Korean native cattle. Analytic data were collected from 973 heads of male calves tested at Korea Native Cattle Improvement Centre from 1985 to 1988. Body weight at birth, weaning. yearling, and gain from weaning to yearling were affected highly(99.99%) by testing year-season and location at birth but the effects of parity was a little significant for growth traits. As data of chest girth at yearling showed highly skewed distribitions. it might be requested for transformation of data for genetic evaluation.
