中文摘要 | 本試驗之目的乃在測定自選飼糧的飼養制度,對產蛋期白色來航雞產蛋 性能與蛋殼品質的影響。試驗雞隻為32週齡白色來航雞40隻,逢機分配於對照組 與自選飼糧處理組。對照組只給飼一完全飼糧(CP 18.09,ME 2858Kcal/Kg),自選 飼糧處理組則同時給飼一完全飼糧(同對照組)與高蛋白質飼糧。試驗結果顯示: 自選飼糧的飼養制度可增進產蛋量、蛋殼厚度與蛋殼強度(P<0.05),此可能是攝 取較多蛋白質、能量與鈣的原故。自選飼糧處理組血漿鈣濃度顯著高於對照組。 但產蛋率(hen-day)與蛋重方面,對照組與自選飼糧處理組間則無顯著差異 (P>0.05)。 |
英文摘要 | The purpose of this study were to determine the effects of self-selectfeeding regimen on egg production, and egg shell quality of White Leghorn.Forty 32-week- old laying hens were randomly divided into 2 treatment groups,which were a control and a self-select regimen. The control group was fed acomplete diet (CP 18.09, ME 2858Kcal/Kg). The self-select group was fedcomplete diet (identical to the control group described above) and high proteindiet simultaneously. Results were as follows: The self-select feeding regimen had significantly improved daily egg mass,egg shell thickness, and egg shell strength (p< 0.05), which probably resultedfrom the significantly increased protein, energy, and calcium intake. The plasmacalcium concentration of self-select group were higher than that of controlgroup (p< 0.05). But there was no differences on hen-day egg production andegg weight between control and self-select groups. |
