中文摘要 | 本試驗採用32頭二品種 (L及Y) 肥育豬,平均體重為47.5kg,依體重及性別逢機 分配入四個飼料處理組中。各飼料處理內容如下: 第一組含 3% 粗纖維 (對照 ); 第二組含 3% 粗纖維並添加 0.05% 飼料級β - 甘露聚醣誨; 第三組含 4% 粗纖維並添加前述之酵素 ;第四組含 5% 粗纖維飼料並添加前述之酵素。試驗結果顯示在 3% 粗纖維飼料中添加酵素 ,有減少飼料攝食量的趨勢。 當飼料粗纖維含量升高時,飼料攝食量亦隨之提高 (p<0.05) 。 在 3% 及 4% 粗纖維飼料中添加酵素, 其飼料效率較 5% 粗纖維並添加酵素組者為佳 (p<0.05) 。 4% 粗纖維並添加酵素組之隻日增重, 在各處理組中最高, 但差異不顯著 (p<0.05)。 平均背脂厚度在 5% 粗纖稚並添加酵素組者為最薄,4% 粗纖維者次之, 而 3% 粗纖維者最厚,但差異並不顯著。至於其他屠體性狀在各處理組而無顯著之差異存在。 |
英文摘要 | Thirty-two, two-way crossbred (Landrace x Large White) finishing pigs weighing 47.5 kg on average were used in the feeding trial. The pigs randomly assigned to four dietary groups. The control diet contained 3% crude fiber. The other three groups contained 3, 4, and 5% crude fiber, and all were supplemented with 0.05% commercial grade beta-mannanase. In the feedig trial, at 3% fiber content, adding enzyme seemed to decrease feed intake. The amount of feed intake increased (p<0.05) with increasing fiber content. The 3 and 4% fiber diets plus enzyme resulted in better feed efficiency compared with that of 5% fiber diet with enzyme group (p<0.05). The 4% fiber diet with enzyme provided the highest average daily gain (p>0.05). The pigs fed 5% fiber plus enzyme diet had the thinnesst backfat, followed by 4% fiber with enzyme group, the control group, and the 3% fiber plus enzyme group, in that order. There were no other significant differences in carcass traits among all the study groups. |
