中文摘要 | 本試驗以尼羅草臺畜草一號之乾草及半乾青貯料為材料,於完全混合日糧中取代進口百慕達乾草餵飼泌乳牛,以探討泌乳情形。以尼羅草乾草為試驗組及百慕達乾草為對照組測試結果,百慕達乾草組4/%脂肪校正乳量25.8 kg/day/cow,與尼羅草乾草組之24.6 kg/day/cow差異不顯著。乾物質採食量百慕達乾草組為19.9 kg/day/cow,與尼羅草乾草組19.4 kg/day/cow差異不顯著。另以尼羅草半乾青貯料為試驗組之採食量20.3 kg/day/cow比使用百慕達乾草組採食量21.0 kg/day/cow顯著降低,但4%脂肪校正乳量尼羅草半乾青貯料組為32.4 kg/day/cow,與百慕達乾草組之31.9 kg/day/cow差異不顯著,以飼糧轉換效率計算尼羅草半乾青貯料組為1.59,與百慕達乾草組之1.52差異不顯著。尼羅草乾草及百慕達乾草兩組餵飼泌乳牛之生乳品質中乳脂率、乳蛋白率、比重、總固形物及體細胞數等兩組間並無差異,乳糖率則以百慕達乾草組之4.84%顯著地高於尼羅草乾草組之4.48%。而餵飼尼羅草半乾青貯料組之生乳品質,乳脂率、乳蛋白率、乳糖率、總固形物、比重及體細胞數等皆與百慕達乾草組之間無差異。各組泌乳牛之血液生化檢驗結果包括尿素氮(BUN)、天門冬酸轉胺酶(AST)、總蛋白質(TP)、鈣(Ca)、鈣/磷比(Ca/P)、膽固醇(CHOL)、白蛋白(ALB)、及γ-麩胺醯轉換酶(GGT)等均在正常值內,顯示餵飼尼羅草乾草及半乾青貯料並影響牛隻之血液成分,因此建議尼羅草乾草或半乾青貯料可替代進口的百慕達乾草餵飼泌乳牛。 |
英文摘要 | The objectives of this experiment were to evaluate the lactation performance of Holstein dairy cows when fed on total mixed ration prepared with hay or haylage of Nilegrass Taishu No.1 (NLT1) and to compare the performance of Bermudagrass (BD) hay. The results showed that the yields of 4% fat-corrected milk (FCM) produced by dairy cows fed on BD hay and NLT1 hay were 25.8 and 24.6 kg/day/cow, respectively, No significant difference between them was observed. The dry matter intake (DMI) of dairy cows fed on BD hay was 19.9 kg/day/cow higher than of NLT1 hay with 19.4 kg/day/cow, but it was not significantly different. The second experiment showed that the FCM yield fed on NLT1 haylage was 32.4 kg/day/cow, higher than that fed on BD hay with 31.9 kg/day/cow, and no significant difference was observed. The feed conversion ratios of dairy cows fed on NLT1 haylage and BD hay were 1.59 and 1.52, respectively. The milk compositions, such as milk fat, milk protein, gravity, total solids and number of somatic cell of dairy cows were not significantly different between feeding on NLT1 hay and BD hay and between feeding on NLT1 haylage and BD hay. The milk lactose content of dairy cows fed on BD hay was 4.84%, higher than that fed on NLT1 hay. However, it was not different for milk lactose content between feeding on NLT1 haylge and BD hay. The biochemical values of blood included blood urea nitrogen (BUN), aspartate aminotransferase (AST), total protein (TP), calcium (Ca), phosphorus (P), cholesterol (CHOL), albumin (ALB) and γ-glutamyltransferase (GGT) were all fell within the normal physiological ranges and not significantly different between treatments for both experiments. It showed that the lactation performance of Holstein dairy cows fed on total mixed rations prepared with NLT1 hay or haylarge was as good as that with Bermudagrass hay. |
