Abstract

A Total of 48,101 performance records of sows for Yorkshire and Landrace breeds were collected from swine breeding farms in Korea from 2001 to 2008. A general ingredient analysis included the fixed effects of breed, parity, year, season, and farm. For the number of heads per 1st parity analysis by each growth traits, the data of 48,101 heads was used to analyze growth traits group. In the general ingredient analysis, the results showed high significance except for lean percentage by season (p<0.05). Average daily gain of Landrace breed ($640.48{\pm}0.749g$) was better than that of Yorkshire breed ($624.22{\pm}0.608g$), and the backfat thickness of Yorkshire breed ($13.44{\pm}0.030mm$) was thicker than that of Landrace breed ($12.50{\pm}0.037mm$). For the number of born alive and number of stillborn by growth traits for each breed, number of born decreased after test end day of 161 to 165 day, and average daily gain of 620 g to 640 g and the highest number of born appeared at the backfat thickness of 13 mm to 14 mm for yorkshire breed. In case of Landrace breed, number of born was the highest, and the number of stillborn increased together with average daily gain. The number of born was high when backfat thickness was less than 11 mm. The number of born trended to decrease when backfat thickness increased.

본 연구에 이용한 재료는 2001년부터 2008년까지 한국 종돈장에서 농장검정된 Yorkshire종, Landrace종의 암컷 48,101두의 자료를 이용하였다. 일반성분 분석은 품종별, 산차별, 년도별, 계절별 및 농장별로 분석하였고, 각 성장형질별 1산차 산자수 분석은 48,101두의 자료를 이용하여 성장형질 그룹별로 분석하였다. 일반 성분 분석에서 품종의 정육율 (p<0.05)을 제외한 부분에서 고도의 유의성(p<0.01)을 나타내었다. 일당증체량에서는 Landrace종 ($640.48{\pm}0.749g$)이 Yorkshire종 ($624.22{\pm}0.608g$)보다 우수하였으며, 등지방 두께에서는 Yorkshire종 ($13.44{\pm}0.030mm$)이 Landrace종 ($12.50{\pm}0.037mm$)보다 두껍게 나타났다. 각 품종에 대한 성장형질별 1산차 산자수 와 사산두수에서 Yorkshire종은 종료일령 161~165일령그룹을 기점으로 산자수가 감소하는 경향을 보였으며, 일당증체량 620~640 g그룹과 등지방두께 13~14 mm그룹에서 산자수가 가장 많이 나타났다. Landrace종의 경우 일당증체량그룹에서 일당증체량이 증가할수록 산자수와 사산두수가 증가하는 경향을 보였다. 등지방두께그룹에서 11 mm미만 구간에서 산자수가 가장 많았고, 등지방두께가 증가할수록 산자수는 감소하는 경향을 보였다.
