Pemanfaatan limbah wortel dalam ransum dan pengaruhnya Terhadap metabolisme rumen dan performan produksi Sapi perah

Penelitian bertujuan untuk mengetahui pengaruh subtitusi rumput lapangan oleh limbah wortel dalam ransum terhadap metabolisme rumen dan produksi susu sapi perah. Percobaan dilakukan dua tahap yaitu menguji metabolisme rumen in vitro dan menguji produksi susu pada 20 ekor sapi perah laktasi yang diberi empat macam ransum perlakuan dalam lima ulangan. Perlakuan berupa R0 (66% Rumput + 34% konsentrat), R1 (60% Rumput + 40% konsentrat), R2 (33% ‘Rumput + 33% daun wortel+34% konsentrat), dan R3 (33% Rumput + 16,5% daun wortel + 16,5% umbi wortel + 34% konsentrat) semua disusun berdasarkan bahan kering 100%. Peubah yang diamati adalah fermentabilitas, kecernaan ransum, dan performans produksi sapi perah. Hasil penelitian menunjukkan bahwa subtitusi 50% rumput lapang oleh Iimbah wortel dalam ransum meningkatkan kecernaan bahan kering dan organik ransum in vitro walaupun tidak mempengaruhi fermentabilitasnya, serta memperbaiki produksi susu 4% FCM dan meningkatkan etisiensi ransum in vivo.

The objectives of the research were to study the utilization of carrot waste as native grass substitution in ration and its effect on the rumen metabolism and production performance of dairy cows. A series of experiments were conducted as follows: The first series experiment was initiated by an in vitro trial designed to study the in vitro rumen metabolism. The second series of experiment was designed to study the production performance of dairy cattle. The experimental methods were arranged in Randomized Block Design with four treatments and tive times replications. The treatments were R0 (66% native grass + 34% concentrate), R1 (60% native grass + 40% concentrate), R2 (33% native grass + 33% carrot leaf + 34% concentrate), dan R3 (33% native grass + 16.5% carrot leaf + 16.5% carrot tuber + 34% concentrate) all based on dry matter 100%. The results indicated that the utilization of carrot waste as native grass substitution increased the ration dry matter and organic matter digestibility, milk production 4% FCM dan feed efficiency.
