Abstract

This study aimed to determine the in vitro nutrient digestibility of complete silage from Sorghum bicolor (L.) Moench using different additives. The method used was a completely randomized design containing 4 treatments and 4 replications, namely, R1: Sorghum bicolor (L.) Moench + L. leucocephala (without additives/control), R2: Sorghum bicolor (L.) Moench + L. leucocephala + 20% rice bran + 10% rock sugar, R3: Sorghum bicolor (L.) Moench + L. leucocephala + 20% corn meal + 10% rock sugar, R4: Sorghum bicolor (L.) Moench + L. leucocephala + 20% pollard + 10% rock sugar. The additive material percentage was calculated based on the chopped weight of Sorghum bicolor (L.) Moench and L. leucocephala. The data obtained were assessed by the analysis of variance, and then continuously analyzed by the Duncan's multiple range test. The Sorghum bicolor (L.) Moench plants were harvested on 70 days after planting and withered for 3 hours to reduce the moisture content, and then chopped at 3 cm size. The chopped results were mixed with the additive materials based on the treatments and their percentages applied, and then moved to the plastic container (silo), the mixture that was moved into the silo was suppressed to make the chopped layer solid (anaerobic principal). Ensilage process was stood for 21 days. The complete silage was removed, and its in vitro nutrient digestibility was analyzed. The results showed that the use of additives could improve the dry matter, organic matter, N-NH3, and VFA digestibility of complete silage from Sorghum bicolor (L.) Moench. It can be concluded that the additive supplementation of 20% pollard and 10% rock sugar can improve the dry matter, organic matter, N-NH3, and VFA digestibility of complete silage from Sorghum bicolor (L.) Moench.

Abstract

Penelitian ini bertujuan membandingkan kualitas ransum yang dibuat sendiri dengan ransum konvensional terhadap penampilan (PBBH ), konsumsi ransum, dan konversi ransum ayam broiler, dilaksanakan di kandang peternakan, Fakultas Pertanian Universitas Timor, Kabupaten Timor Tengah Utara selama 1 (satu) bulan lebih berlangsung dari tanggal 17 Februari sampai dengan 24 Maret 2015. Masing-masing ransum di berikan pada ayam Broiler dari umur 0-35 hari atau 5 minggu dengan melihat penampilan ayam broiler dan PBBH. Jumlah ayam broiler yang digunakan sebanyak 80 ekor. Hasil penelitian menunjukkan perlakuan ransum buatan memberikan pengaruh yang lebih baik terhadap pertambahan bobot badan, konsumsi dan konversi ransum. Bobot badan akhir umur 35 hari pada perlakuan ransum buatan dengan rataan pada kisaran 184,58-223,15 gram/ekor; dengan rata- rata akhir 205,39 gram/ekor lebih tinggi dibandingkan pada perlakuan ransum konvensional yang menghasilkan kisaran rataan 181,88-209,91 gram/ekor; dengan rata-rata 194,62 gram/ekor. Konsumsi ransum selama 35 hari pada perlakuan ransum buatan pada kisaran rataan 629,39-658,78 gram/ekor, dengan rata-rata 640,43 gram/ekor, lebih rendah dibandingkan pada perlakuan ransum konvensional yang menghasilkan rataan 695,15-728,48, dengan rata-rata 713,81 gram/ekor. Konversi ransum pada perlakuan ransum buatan berada pada kisaran ratan 2,81-3,48 gram/ekor, dengan rata- rata konversi ransum 3,12 gram, lebih baik dibandingkan pada perlakuan ransum konvensional yang menghasilkan kisaraan rataan 3,08-3,88 gram/ekor, dengan rata-rata konversi 3,67 gram. ©2016 dipublikasikan oleh JAS.
