本 試驗硏究는 國內에서 많이 飼育되고 있는 品種中에서 低營養水準에 適應이 잘되는 品種을 選拔하기 爲하여 春季出産豚은 Landrace, Berkshire 및 Large white 三品種을 秋季出産豚은 Landrace, Berkshire 二品種을 가지고 試驗을 實施한 바 그 結果는 다음과 같다. 1. 日當增體量은 春季出産豚의 境遇 A飼料給與區는 Large white 0.668㎏, B飼料給與區는 Berkshire가 0.501㎏으로써 다른 比較品種보다 좋은 增體成績을 나타냈고, 秋季出産豚의 境遇 A飼料區는 Landrace보다 優秀한 增體成績을 나타냈다. 2. 屠體率 및 精肉率은 各各 Berkshire가 春季出産豚의 境遇 A飼料給與區에서 76.6%, 70.1%, B飼料給與區에서 73.2%, 63.2%로서 가장 優秀했고, 秋季出産豚의 境遇도 A飼料區 77.2%, 68.1% B飼料區 74.7%, 64.7로 優秀했다. 3. 背脂肪두께는 Landrace가 A, B飼料給與區 各各 春季出産豚의 境遇 2.7㎝, 2.8㎝ 秋季出産豚의 境遇 2.8㎝, 3.2㎝로 다른 比較品種에 比하여 좋은 成績을 나타내었다. 4. 飼料要求率에 있어서는 A飼料給與區의 境遇 春, 秋 모두 Landrace가 B飼料給與區의 境遇 Berkshire가 第一 좋은 成績을 나타내었다. 5. 以上을 綜合해 볼 때 高營養飼料水準에서는 Landrace, Large white가 有利하고 低學養飼料水準에서는 Berkshire가 有利한 品種으로 나타났다. The experimental animals were Landrace, Berkshire and Large White pigs farrowed in the spring, and Landrace and Berkshire pigs farrowed in Fall. The results obtained in this study suggest the Landrace and Large white are more profitable under the high feeding regime and Berkshire is the more profitable breed under the low feeding regime.

The present study was carried out to study the possibility of selecting the breed that is adapted to low nutritional level in swine. The experimental animals were Landrace, Berkshire, and Large white pigs farrowed in the spring, and Landrace and Berkshire pigs farrowed in the fall. The results obtained are as follows. 1. The Largewhite had the highest average daily gain of 0.668kg under the high feeding regime, and the Berkshire had higher average daily gain of 0.501kg under the low feeding regime in the spring farrowed pigs. The Landrace had the highest average daily gain of 0.568kg under the high regime and the Berkshire had higher average daily gain of 0.458kg under the low regime in the the fall farrowed pigs. 2. The Berkshire had the highest dressing percentage and lean meat percentage under both regime: 76.6% and 70. 1% under the high regime and 73.2% and 63.2% under the low regime in the spring farrowed pigs, and 77.2% and 68.1% under the high regime and 74.7% under the low regime in the fall farrowed pigs. 3. The Landrace had the thinnest backfat: 2.7cm and 2.8cm under the high and low regimes in the spring farrowed pigs and 2.8cm and 3.2cm in the fall farrowed pigs. 4. In the feed efficiency, the Landrace showed the best result under the high, regime, and the Berkshire showed the best result under the low regime in both spring and fall farrowed pigs. 5. The results obtained in this study suggested that the Landrace and Large’ white are more profitable under the high regime and the Berkshire is the more‘ profitable breed under the low regime.
