干拓地에서 栽培한 설탕무우 Silage가 育成豚의 成長에 미치는 效果 = Effect of Sugar beet Silage On body Weight gain of pigs

국문 초록 (Abstract)

本 試驗은 育成豚에 對한 설탕무우 사일레지의 飼料價値 및 適正 給與水準을 究明하기 위하여 실시하였다. 즉 설탕무우 사일레지를 0, 15, 30, 45, 그리고 60% 까지 代置 給與하여 三元雜種(Nandrace × Chester white × Yorkshire), 30頭를 供試하고 約80日間으 飼養試驗을 實施하였던 바 그 結果를 要約하면 다음과 같다.
1. 총 增體量은 설탕무우 사일렌지 給與水準이 0, 15, 30, 45, 그리고 60%로 높아짐에 따라 각각 56.9, 57.1, 57.2 그리고 59.6kg으로서 큰차이가 없었다.
2. 日당 增量은 處理區別로 705, 707, 708 및 738g으로서 설탕무우 사일렌지 水準 增加에 따라 같거나 다소 높은 경향이나 統計的인 有意差는 인정되지 않았으며 飼料要求量도 3.83, 3.81, 3.89, 3.89 및 3.76kg으로서 차이가 없었다.
3. 설탕무우 사일렌지 水準增加에 따라 등지방이 얇아지는 경향이었으며,
4. 增體kg當 飼料費는 설탕무우 사일렌지를 많아 給與하였을때가 가장 經濟的이었다.
5. 以上의 結果로 볼때 설탕무우 사일렌지를 곡류와 代置하여 60%까지 給與하여도 좋은 것으로 思料된다.

다국어 초록 (Multilingual Abstract)

Thirty erossbred pigs (Landrace x Chestwhite x Yorkshire) were used to study the effect of sugarbeet silage (0, 15, 30,45,60 %) as a replacement of grains in rations from weanling to marlcet weight on the .dry lot performance, carcass quality and feed cost per kg gain.
The results obtained are as follows.
1. Body weight gain for 0, 15, 30, 45 and 60 % level of sugarbeet silage were 56. 9, 57, 1, 57.1, 57.2 and 59.6kg respectively.
2. Average daily gain was 705, 707, 707, 708 and 738kg respectively and tended
to increase as the level of sugarbeet silage in the ration increased. However, there were on satistical differences between the levels.
The amount of feed required per kg gain were 3. 83, 3. 81, 3. 89, 3. 89 and 3. 76kg respectively.
3. As the level of sugarbeet silage increased, back fat thickness tended to thin.
4. Feed cost per kg gain was the cheapest at the highest level of sugarbeet silage
used.
5) Above result indicate that up to 60 % level of sugarbeet silage in the rations gave satisfactory gains, feed efficiency, carcass quality and feed cost per kg gain.
The effect of sugarbeet silage in growing finishing pigs ration on performance and .carcass quality was studied.
Up to 50 % level of sugarbeet silage in the ration indicated satisfactory results.
