Kadar NPK Feses Domba Garut yang Diberi Ransum Mengandung Silase Daun Rami (Boehmeria nivea)

ABSTRAK                                                            Penelitian bertujuan mengevaluasi ransum mengandung silase daun rami ( Boehmeria nivea ) terhadap kandungan BK dan NPK feses domba garut. Penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan, yaitu R1 = 100% rumput R2 = 60%   rumput + 40% konsentrat, R3 = 30% silase daun rami + 30% rumput + 40%  konsentrat, R4 = 60% silase daun rami +40% konsentrat. Masing-masing perlakuan diulang sebanyak lima kali. Data hasil penelitian dianalisis ragam dan dilanjutkan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa penggunaan silase daun rami sampai tingkat 60%  dalam ransum domba garut nyata mempengaruhi BK, kadar abu dan K (P<0,05), tetapi tidak mempengaruhi kandungan N dan P feses domba. Pemberian silase daun rami sebanyak 60% dalam ransum menghasilkan kandungan abu feses tertinggi (25,49%) serta menghasilkan 33,55-40,89% BK, 2,27-2,53% N, 0,57-0,67% P dan 0,21-0,34% K. Kesimpulan, penggunaan silase daun rami sampai tingkat 60% berpotensi sebagai pupuk organik dalam menyediakan unsur N,P, dan K bagi tanaman.

The study used a completely randomized design (CRD) with four treatment, namely R1 = 100% grass; R2 = 60% grass + 40% concentrate; R3 = 30% silage of Boehmeria nivea leaf + 30% grass + 40% concentrate; and R4 = 60% silage of Boehmeria nivea leaf + 40% concentrate. Each treatment was repeated five times. The data obtained were analyzed by variance of analysis and continued with Duncan's multiple range test. The results showed that the use of Boehmeria nivea leaf silage up to 60% in garut sheep ration significantly affected the dry matter (DM), ash, and K content (P <0.05), but did not affect the N and P content of sheep feces. Giving silage of Boehmeria nivea leaf up to 60% in the ration produced the highest fecal ash content (25.49%), 33.55-40.89% DM, 2.27-2.53% N,0.57-0.67% N and 0.21-0.34% K. This research concludes that the use of Boehmeria nivea leaves silage up to 60% has the potential as an organic fertilizer in providing N, P, and K elements for plants.
