Abstract
This study was conducted to determine the main effect of the breed, parity, forrowing year and month on average daily gain, feed efficiency, backfat thickness, age at 90 Kg body weight and selection index. The data analysis were the record of 115 male pigs producted from Landrace. Large Yorkshire and Duroc purebreds tested at Chungnam Province Animal Breeding Station from 1986 to 1990. The results obtained are summarized as follows : 1. The breed average of daily gain, feed efficiency, backfat thickness, age at 90Kg body weight and selection index were
본 연구(硏究)는 1986년부터 1990년까지 충청남도(忠淸南道) 도립종축장(道立種畜場)에서 사육된 Landrace, Large Yorkshire 및 Duroc종의 후보종 모돈 115두의 이유후 형질(形質)에 대한 능력검정(能力檢定) 자료를 근거로 최소자승법을 이용하여 품종(品種), 산차(産差), 분만년도(分娩年度) 및 분만월(分娩月)이 일당증체량(日當增體量), 사료요구율, 등지방층두께, 90kg도달일령 및 선발지수에 미치는 효과(效果)를 추정(推定)하였던 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 이유후형질(形質)의 전체평균은 일당증체량(日當增體量), 사료요구율, 등지방층두께, 90kg도달일령 및 선발지수(選拔指數)에서 각각
