Peningkatan Kinerja Laktasi Sapi Bali (Bibos banteng ) Beranak Pertama Melalui Perbaikan Mutu Pakan

Abstract

Sapi Bali (Bibos banteng) adalah salah satu jenis ternak potong asli Indonesia yang dapat dimanfaatkan sebagai sumber plasma nutfah untuk pengembangan sapi potong di Indonesia. Hal ini mengingat sapi Bali memiliki beberapa keunggulan dibanding jenis sapi lain (yang ada di Indonesia) yaitu antara lain tingkat reproduksi yang tinggi, nilai karkas yang tinggi, serta adaptif terhadap lingkungan tropis. Dengan terjadinya seleksi negatif secara term menerus, belum intensifiya pelaksanaan inseminasi buatan. serta pakan bennutu rendah mengakibatkan produktivitas sapi Bali semakin menurun.

A study was conducted to improve milk production performance of first lactating Bali cows through better quality of rations during a period of 16 weeks immediately after calving. Twelve lactating cows (initial BW 263.79 ± 21.66 kg) were randomly assigned into 4 dietary treatment groups: A, B, C, and D, and 3 blocks as replicates where each replicate was represented by a single cow. The rations consisted of locally available feed stuffs offered ad libitum. The cows were accustomed to the diet since 2 months prior to calving. Diet A contained 70% elephant grass (PP, Pennisetum purpureum) plus 30% Gliricidia sepia leaves (GS), B was 30% PP plus 25% GS supplemented with 15% Hibiscus tilliacius leaves (HT, defaunating effect), C was 75% B plus 25% concentrate, and diet D was C supplemented with 0.006% zinc acetate.
