中文摘要 | 為探討胺基酸平衡與不平衡對豬隻生長、屠體性能和氮蓄積之影響,四種等能量但不同銨基酸比例的飼料處理組:玉米─大豆粕為主(粗蛋白質9.38%,離胺酸0.30%)再補充合成離胺酸至0.70%之基礎飼糧(處理1);或基礎飼糧補充羥丁胺酸、色胺酸(處理2)和甲硫胺酸(處理3),與高蛋白質之玉米─大豆粕飼糧(含粗蛋白14.3%,離胺酸0.70%)而不補充任何合成胺基酸(處理4)。試驗採用64頭生長豬(平均體重30kg)逢機分配於上四種飼料處理中,豬隻採個別飼養,每日餵飼兩次,至體重55kg和95kg,在體重達95kg時屠宰進行屠體測定。生長試驗結果顯示,體重30-55kg或55-95kg豬隻之每日增重與飼料利用效率以處理3與高蛋白組獲得顯著(P<0.01)的改善,但每日增重與屠體性能都已高蛋白質組最優。代謝試驗採用12頭(9個重複)女豬(平均體重40kg)逢機分配於上述四種飼料處理中。氮蓄積以處理3與高蛋白質組獲得較佳(P=0.06)的改善趨勢。氮蓄積的反應印證了生長屠體性能之結果。 |
英文摘要 | The effect of amino acid balance and imbalance on growth, carcass characteristics, and nitrogen retention of growing pigs was investigated. The four diets were formulated with similar digestible energy values, but different amino acid proportions: synthetic lysine to 0.70% as a basal diet (treatment 1), basal diet supplemented with threonine and tryptophan (treatment 2) or methionine (treatment 3) and a crude protein of 14.3% in corn-soybean meal with 0.70% lysine level (treatment 4). Sixty-four pigs were used for the growth trial from 30 to 55 kg and 55 to 95 kg live weight. The pigs were individually fed twice daily and slaughtered after attaining a live weight of 95 kg. Carcass characteristics were measured. For the 30 to 55 kg and the 55 to 95 kg live weight, significant improvements (P<0.01) in daily gain and feed to gain ratio were observed for the amino acid proportions of treatment 3 and the high protein diet, but the high protein treatment revealed the highest daily gain and carcass characteristics. Twelve gilts (9 replicates) were used for the metabolism trial at 40 kg live weight and arranged into the four diets as described above. Nitrogen retention improved (P=0.06) with the treatment 3 and high protein diet. The response criterion of nitrogen retention lent further support to the growth and carcass characteristic data. |
