中文摘要 | 本試驗之目的乃在測定自選飼糧的飼養制度,對5至8週齡白肉雞的生長 性能、上市品質與採食行為的影響。試驗雞隻為29日齡白肉雞128隻,逢機分配 於一個對照組與三個自選飼糧處理組中,各處理有2欄,每欄16隻雞。對照組給 飼含粗蛋白質20、代謝能3140kcal/kg的完全飼糧。三個自選飼糧處理組則除給飼 與對照組相同的完全飼糧外,並再分別供應一低熱能蛋白質比(S1)、或低營養濃 度(S2)、或高營養濃度的飼糧(S3)供雞隻自由選擇採食。試驗結果顯示:自選飼糧 的飼養制度並未改善白肉雞生長性能與上市品質(P>0.05)。而以同時提供完全飼 糧與低營養濃度飼糧(S2)供白肉雞自由選擇的飼養制度,將因代謝能與粗蛋白質 攝取量的不足,致使生長發育遲緩。以自選飼糧的飼養制度飼養的白肉雞在 18.O0-07.OOh期間,對高營養濃度飼糧的採食量較高。 |
英文摘要 | The purpose of this study were to determine the effects of self-selectfeeding regimen on growth performance, marketing qualities, and feeding behavior of broiler during 5 to 8 weeks of age. One hundred and twenty-eight 29day-old broiler chicks were randomly allotted into 4 treatment groups whichwere one central and three self- select regimens. In each treatrment included 2floor pens, each containing 16 birds. The control group was fed a completediet (CP 20, ME 3140Kcal/Kg). All of three self-select regimens were fedcomplete diets (indentical to the complete diet described above) exceptably,and fed low energy/protein ratio diet (S1), low density diet (S2), and highdensity diet (S3) respectively. Results were as follows: Dietary self-selection had no effect on growth performance and marketingqualities of broiler (p>0.05). The S2 had significantly reduced growth rate,which probably resulted from the significantly reduced energy and protein intake. The broiler chicken allowed to self- select nutrients showed preferences forhigh density diet between 18.00 and 07.00h. |
