中文摘要 | 試驗採用80頭豬隻,以探討來自游離型或大豆粕之離胺酸添加於飼料對豬隻性能的影響。基礎飼料為玉米82.87%和大豆粕13.6%和離胺酸量0.59%,再添加0.2%離胺酸(L-離胺酸-鹽酸)或大豆粕(降低玉米用量)於基礎飼料中,駛離胺酸總量皆為0.74%。64頭大白豬,包括閹公豬和肉女豬,以上述兩種飼料分別以每日二次或任食飼養,而每日二次之飼料餵量為任食飼養者前一週的飼料量。試驗自體重25kg飼養至95kg屠宰。結果顯示豬隻在不同的飼養方法下,兩種不同來源的離胺酸對於豬隻之生長性能和屠體品質皆無顯著的差異。又試驗採用藍瑞斯×大白豬之雜交肉女豬16頭,平均體重為55~60kg,進行氮平衡試驗。試驗亦採用上述生長試驗之設計,5天的試驗期間收集豬隻尿液,以測定尿氮素(urinary nitrogen)作為反應之依據。尿氮素之測定印證了生長性能和屠體品質之結果。 |
英文摘要 | A total of eighty pigs were used to examine the effects of adding lysine in free form or in soybean meal to pig diets. The basal diet was of 82.87% corn and 13.60% soybean meal, and its lysine concentration was 0.59%. Additions of 0.20% lysine as L-lysine-HCl or in soybean meal were included at the expense of corn to give the same total lysine content of 0.74%. The 64 Large White pigs, consisting of castrates and females were fed the diets at the same daily rate twice daily or ad libitum, according to the adjustment of their weekly weights. Measurements began at 25 kg and continued until slaughter at 95 kg. The growth and carcass quality did not differ significantly between the two sources of lysine under varying feeding methods. 16 Landrace × Large White gilts initially weighing 55 to 60 kg each, received the above treatments according to the same 2×2 factorial design. The response criterion was urinary-nitrogen excretion gave a good support to the observation of growth and carcass response. |
