초록
본 연구에서는 2000년부터 2008년 사이에 출생한 Duroc종, Landrace종 및 Yorkshire종의 GGP (Great Grand Parents) 종돈 31,455두의 농장검정자료를 이용하여 단변량 모체효과 모형에 의한 돼지의 경제형질에 대한 유전모수 및 유전력 추정을 통해 모체효과가 돼지의 경제형질에 미치는 영향에 대하여 알아보았다. 조사된 모든 형질에서 각 요인에 대한 유의성을 검정한 결과 모든 형질에 있어서 품종, 성, 출생년도, 출생계절 및 산차의 효과는 고도의 유의성이 인정되었고 (p<0.01), 모체효과 모형을 이용하였을 때 각 품종별 형질에 대해 추정된 상가적 유전 분산과 모체 유전 분산사이에 부 (-)의 공분산이 존재하고, 이들의 유전 상관도 대부분 강한 부 (-)의 상관관계를 보여 품종, 형질 및 개량 방향에 따라 모체 효과뿐만 아니라 상가적 효과와 모체 효과간의 상관관계도 적절히 고려한다면 좀 더 효율적인 개량효과를 거둘 수 있을 것으로 사료된다.
Abstract
This study looked into how much maternal genetic effect influenced on economic traits through estimation of genetic parameter and heritability over swine's economic traits by maternal animal model using GGP farm examination data of total 31,455 swine of Duroc species, Landrace species and Yorkshire species that were born between 2000 and 2008. As a result of significance test over each factor in surveyed all traits, high significance was approved in the effect of breed, gender, the date of swine's birth, the season swine's born, and difference in delivery in every trait (p<0.01). It is considered that it would be possible to get more efficient improvement effect provided correlation between additive genetic effect and maternal genetic effect as well as maternal genetic effect according to breed, traits, and improvement direction are properly considered as negative covariance existed between additive genetic distribution and maternal genetic distribution presumed for traits by each breed and their genetic relation also showed mostly strong negative correlation.
