2014Basri (I 211 09 279). Kecernaan Bahan Kering dan Bahan Organik Ransum \ud Komplit Dengan Kandungan Protein Berbeda Pada Kambing Marica Jantan. \ud (Dibawah bimbingan Prof. Dr. Ir. Asmuddin Natsir, M.Sc sebagai Pembimbing \ud Utama dan Ir. Muhammad Zain Mide, MS sebagai Pembimbing Anggota). \ud \ud ABSTRAK \ud Bentuk ransum serta ketersediaan dan keseimbangan nutrisi dalam ransum, \ud misalnya pada ransum komplit, akan berpengaruh terhadap pemanfaatan nutrisi \ud ransum tersebut. Penelitian ini bertujuan untuk mengetahui kandungan protein \ud kasar ransum komplit yang dapat mengoptimalkan tingkat kecernaan bahan kering \ud dan bahan organik ransum komplit pada kambing merica jantan. Penelitian ini \ud dilaksanakan menurut rancangan acak lengkap terdiri dari empat perlakuan dan \ud tiga ulangan. Perlakuannya adalah A. Ransum komplit dengan kandungan protein \ud 10.20%, B. 12.59%, C. 15.24%, dan D. 17.54%. sebanyak dua belas ekor \ud kambing merica jantan ditempatkan pada kandang individu dan secara acak \ud mendapat salah satu dari empat jenis ransum percobaan. Hasil percobaan \ud memperlihatkan bahwa rataan daya cerna bahan kering bervariasi antara 62.8 % \ud (ransum B) sampai 66.5% (ransum D). Rataan daya cerna bahan organik \ud bervariasi antara 60.7% (ransum B) hingga 65.6% (ransum D). Namun demikian \ud hasil statistik memperlihatkan bahwa perlakuan tidak memberikan pengaruh yang \ud nyata (P>0.05) terhadap daya cerna bahan kering dan bahan organik ransum \ud komplit. Kesimpulan, meningkatkan kadar protein ransum komplit dari 10% \ud menjadi 17.5% tidak memberikan kontribusi yang signifikan terhadap \ud peningkatan kecernaan bahan kering dan bahan organik ransum komplit. \ud \ud Kata Kunci : Kambing Marica, Kecernaan Bahan Kering dan Bahan \ud Organik, Ransum Komplit \ud \ud \ud \ud \ud \ud \ud 9 \ud \ud Basri (I 211 09 279). Dry Matter and Organic Matter Digestibility of Complete \ud Ration Containing Different levels of Cride Protein on Male Merica Goat. (Under \ud the guidance of Prof.. Dr.. Ir. Asmuddin Natsir, M.Sc as the Main Supervisor \ud and Ir. Muhammad Zain Mide, MS as a Member Advisor). \ud \ud ABSTRACT \ud The form of ration as well as availability and balancing of nutrient contents of the \ud ration such as in complete ration will affect the utilization of those nutrients by the \ud animal. The purpose of this experiment was to study the level of protein contents \ud of complete ration that could optimize digestibility of dry matter and organic \ud matter of the ration on male marica goat. The experiment was carried out \ud according to completely randomised design consisted of four treatments and three \ud replications for each treatment. The treatments were A. Complete ration \ud containing 10.20% of crude protein, B. Complete ration containing 12.59% of \ud crude protein, C. Complete ration containing 15.24% of crude protein, D. \ud Complete ration containing 17.54% of crude protein. Twelve heads of marica \ud goats were placed into an individual metabolic cage and was randomly fed one of \ud four rations. The results of the experiment showed that dry matter digestibility \ud varied between 62.8% (treatment B) and 66.5% (treatment D). While organic \ud matter digestibility ranged from 60.7% (treatment B) to 65.5% (treatment D). \ud However, statistical analysis indicated that there was no significant differences \ud (P>0.05) among the treatments. In conclusion, increasing crude protein content of \ud complete ration from 10% to 17.5% did not give a significant benefits in terms of \ud dry matter and organic matter digestibility of complete ration for marica goat. \ud \ud Keywords: Marica Goat, Dry Matter and Organic Matter Digestibility, \ud Complete Ration
