본 연구는 재래 돼지의 산육 능력을 개량하기 위한 기초 자료를 제공하기 위하여 축산과학원에서 2001년부터 2006년까지 20 kg에 검정을 개시하고 70 kg에 검정을 종료하여 발육 능력을 조사한 546개의 재래 돼지 산육 능력 검정 자료를 활용하여 유전모수를 추정하였으며, 재래 돼지 사육 농가의 사양방법 개선을 위하여 2003년부터 2005년까지 조사된 재래 돼지성돈 및 검정돈 132두의 발육 단계별 체중 및 체위 조사 자료를 다중 회귀 분석하여 재
Records on 546 Korea native pigs for average daily gain (ADG), age at 70 kg (D70 kg) and backfat thickness (BF) made between 2001 and 2006 in herds on National Institutes of Animal Science in Korea were used to estimate genetic parameters. The data was analyzed by the DF-REML (Derivative-Free Restricted Maximum Likelihood) program of Boldman using a single-trait animal model. Heritabilities were 0.26, 0.09, and 0.29 for ADG, D70 kg and BF, respectively. The phenotypic correlations of ADG with D70 kg and BF were -0.71 and 0.30. The phenotypic correlation of D70 kg with BF was -0.15. The genetic correlations of ADG with D70 kg and BF were -0.11, 0.41, respectively. The genetic correlation of D70 kg with BF was -0.16. The data of weights and measurements on body length, body height and chest width after age at 11 months (days to 330) were shown scarcely less differences compare to data of age at 11 months.
