Pengaruh Imbangan Silase Tebon Jagung dan Konsentrat terhadap Performa Domba Garut Betina di Ananta Farm

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh imbangan silase dan konsentrat dengan penambahan starter fermentasi yang berbeda. Penelitian ini menggunakan 20 ekor domba garut betina, terdiri dari 5 perlakuan dan 4 ulangan. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan, yaitu P0 = 70% Silase tebon jagung + 30% konsentrat; P1 = 70% Silase tebon jagung + EM4 + 30% konsentrat; P2 = 60% Silase tebon jagung + EM4 + 40% konsentrat; P3 = 70% Silase tebon jagung + starter Ananta + 30% konsentrat; P4 = 60% Silase tebon jagung + starter Ananta + 40% konsentrat. Peubah yang diamati meliputi pertambahan bobot badan, konsumsi pakan, konversi pakan, efisiensi pakan, dan income over feed cost (IOFC). Hasil penelitian menunjukkan bahwa penambahan starter fermentasi silase dan variasi imbangan hijauan dan kosentrat tidak berpengaruh nyata (P>0,05) pada total konsumsi nutrien, efisiensi pakan, dan konversi pakan, namun nyata meningkatkan (P<0,05) konsumsi bahan kering konsentrat dan PBBH. Penambahan starter Ananta Farm pada silase tebon jagung dengan imbangan 70% dan 60% hijauan dapat meningkatkan bobot badan dan menghasilkan keuntungan paling baik.

The study aimed to evaluate the effects of silage and concentrate balance with the addition of different fermentation starters. It involved 20 female Garut sheep, comprising 5 treatments and 4 replications. The experimental design used was a Completely Randomized Design (CRD) with 5 treatments: P0 = 70% corn stover silage + 30% concentrate; P1 = 70% corn stover silage + EM4 + 30% concentrate; P2 = 60% corn stover silage + EM4 + 40% concentrate; P3 = 70% corn stover silage + Ananta starter + 30% concentrate; P4 = 60% corn stover silage + Ananta starter + 40% concentrate. Observed variables included weight gain, feed intake, feed conversion, feed efficiency, and income over feed cost (IOFC). The study results showed that the addition of silage fermentation starters and variations in forage and concentrate ratios had no significant effect (P>0.05) on total nutrient intake, feed efficiency, or feed conversion. However, it significantly increased (P<0.05) concentrate dry matter intake and average daily weight gain (ADG). The addition of the Ananta Farm starter to corn stover silage with forage ratios of 70% and 60% successfully increased body weight and yielded the highest profit.
