中文摘要 | 欄舍。 飼糧共五組,分別為以玉米-大豆粕為基礎飼糧作為對照組 (0% 麩皮 )、分別以 5% 與 10% 未經及經發酵之麩皮取 代等量玉米共 4 組試驗飼糧,飼養 4 週。動物飼養結果,以 5% 與 10% 麩皮或發酵麩皮等量取代玉米對生長期肉豬 之生長性狀沒有顯著差異,但是在血液性狀方面,發酵麩皮組有較高的血漿尿素氮與較低總蛋白含量,但是兩者含 量仍在豬隻正常血液生理值範圍內。因此,由前述結果顯示,以經外源性葡聚醣?進行固態發酵麩皮或麩皮可取代 生長期肉豬飼糧中 5 - 10% 之玉米,並不影響生長期肉豬之生長與血液性狀。 |
英文摘要 | This study was to apply DNA recombination technology to construct and screen yeast transformants and to secrete exogenous beta-glucanase for solid-state fermentation of wheat bran. After that, assassination of the impact on growth performance and blood traits through part of the yellow corn in diet replaced with fermented wheat bran or wheat bran for grower pig. In the exogenous beta-glucanase of test results showed that yeast transformants No.9 and 10, respectively possessed 18 and 22 U/mL of hydrolysis of cellulose activity and the hydrolysis of wheat bran to produce reducing glucose content would increase 4.9 - fold compared to wheat bran (22.0 mg vs. 4.5 mg). Experimental animals weighing 30 kg LYD hybrid hogs adopted 30 heads half-male and half-female, and housed in individual pen. Dietary arrangement had five groups, corn- soybean meal as based diet was the control group (0% wheat bran) and 5% or 10% with and without fermentation process of wheat bran to substitute 5% or 10% of the same amount of corn in 4 kinds of experimental diets group during the four weeks of trial period. Animal feeding trials, 5% and 10% yellow corn in diet replaced with the equal amount of wheat bran or fermented wheat bran to raise grower pigs were no significant difference in growth performance, but in the blood traits, fed with containing fermented wheat bran group had a higher level of plasma urea nitrogen and a lower level of total protein content, but both of them were still in the normal physiological value. Thus, the previous results revealed that both of fermented wheat bran through solid-state fermentation process by exogenous beta-glucanase and wheat bran could replace 5-10% of the yellow corn didn’t impact growth performance and blood traits of grower pigs. |
