中文摘要 | 以飼養試驗及代謝試驗來探討肉豬飼糧中添加纖維素�t對肉豬生長性能及纖維等 消化率之影害。在飼養試驗,生長肉豬 (30kg) 及肥育肉豬 (50kg) 各 48 頭,公母各半, 採個飼,逢機分配三個處理組: 對照組及添加纖維素�t A(1m1/kg) 或 B(0.5 g/kg) 處理組 。 纖維素�t A 之活性為濾紙分解活性 (FPA) 18.5 unit/ml, 經甲基纖維素�t活性 (CMCase)6O unit/ml 及木聚糖�t (Xylanase)1016 unit/ml; 纖維素�t B 之活性為 FPA 37.0 unit/g,CMCase 148 unit/g 及 Xylanase 3600 unit/g,生長期飼糧以玉米 -- 大豆 粕為主,而肥育期飼糧以玉米 -- 大豆粕 -- 大麥為主。代謝試驗在生長期及肥育期各利用 24 頭閹公豬,飼糧處理組如飼養試驗,分別收集豬隻糞便以測定纖維等之消化率。 試驗結 果顯示, 豬隻於生長期及肥育期飼糧中添加纖維素�t均可減少每增重 1 kg 所需的飼料量 (P>0.05); 而添加織維素�t B 可顯著提高豬之增重 (P<0.05),但與織維素�t A 組並無顯 著差異。飼糧中添加織維素�t A 或 B 均可顯著提高生長豬及肥育豬之粗纖維、中洗纖維、 酸洗纖維及半纖維素的消化率 (P<0.05),方可提高肥育豬之鈣消化率, 但並不顯著影響能 量消化率; 而添加纖維素�t A 亦可提高肥育豬之氮消化率 (P<0.05)。本試驗結果顯示添加 織維素�t可改善肉豬飼料效率及纖維消化率,降低纖維排泄量。 |
英文摘要 | Three feeding and digestion trials were conducted to evaluate the effects of cellulase supplementation on growth performance and fiber digestibility in growing and finishing pigs. In feeding trials, 48 crossbred pigs for each trial were penned individually and allotted to three dietary treatments based on sex and weight. The treatments were the control and diets supplemented with cellulase A (1 ml/kg) or B (0.5 g/kg). The activities of enzymes were FPA lg.s unit/ml, CMCase Go unit/ml and xylanase 1016 unit/ml in cellulase A and FPA 37.0 unit/g, CMCase 14.8 unit/g and xylanase 3600 unit/g in cellulase B. The control diets were corn-soybean meal-based and corn-barley-soybean meal-based for grower and finisher, respectively. In digestion trials, 24 growers (30 kg) and 24 finishers (50 kg) were used for measuring the digestibilities of crude fiber, acid detergent fiber (ADF), neutral detergent fiber (NDF), and hemicellulose, etc. The results showed that cellulase A or B supplementation decreased the @d/gain (P<0.05) in growing and finishing pigs. Cellulase B improved daily gain (P<0.05). There were no differences in growth or feed/gain between pigs fed diets with cellulase A and B. The digestibilities of crude fiber, ADF, NDF and hemicellulose in grower and finisher were improved by the cellulase supplementation (P<0.05). Cellulases A and B also improved calcium digestibility in finishing pigs. Cellulase A improved digestibility of nitrogen in finisher (P<0.05). These results suggested that cellulase supplementation could improve feed efficiency and digestibilities of fibers, and would decrease the fiber excretion in growing and finishing pigs. |
