ABSTRAKPenelitian ini bertujuan untuk mengetahui karakteristik morfologis dan reproduksi kerbau pampangan di Propinsi Sumatera Selatan. Dilaksanakan di tiga kabupaten yaitu kabupaten OKI, Banyuasin dan Ogan Ilir selama 6 bulan. Metode yang digunakan adalah metode survei. Penarikan contoh bersifat multistage purposive sampling mulai dari penentuan kabupaten, kecamatan, serta peternak. Setelah ditetapkan tiga kabupaten lokasi sampel, akan dipilih masing-masing satu kecamatan sentra populasi yang jumlah populasinya terbanyak. Data yang dikumpulkan meliputi data primer dan data sekunder. Data yang diperoleh diolah secara matematis, disajikan secara tabulasi kemudian dijelaskan secara deskriptif, yaitu melukiskan secara sistematis fakta atau karakteristik morfologis dan reproduksi kerbau pampangan secara cermat dan faktual dari data yang telah terkumpulkan. Karakteristik morfologis kerbau pampangan adalah warna bulu hitam/hitam keabu-abuan, bentuk tubuh besar, temperamen tenang, kepala besar dan telinga panjang, tanduk ada yang tegak panjang dan melingkar ke arah belakang dan ada juga yang arah ke bawah. Bentuk ambing simetris dan berkembang dengan baik. Karakteristik reproduksi kerbau Pampangan umur pertama kawin rata-rata 2,3 tahun atau 27 bulan, umur beranak pertama 3,23 tahun, estrus (berahi) pertama setelah beranak 88,33 hari, kawin setelah beranak 139,11 hari, jarak beranak 14 bulan dan umur lepas sapih anak 9,07 bulan.Kata kunci: Karakteristik, morfologis, reproduksi, kerbau
An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. The types of rations were: Ration A= 45% fermented kumpai grass + 40% benggala grass + 15% concentrate + 0% lamtoro leaf, Ration B= 45% fermented kumpai grass + 30% benggala grass + 15% concentrate + 10% lamtoro leaf, Ration C= 45% fermented kumpai grass + 20% benggala grass + 15% concentrate + 20% lamtoro leaf, and Ration D= 45% fermented kumpai grass + 10% benggala grass + 15% concentrate + 30% lamtoro leaf. The supplementation of lamtoro leaf up to 30% into the ration could increase (P<0.05) dry matter and organic matter intakes, and crude protein digestibility. The highest body weight gain and feed efficiency were found in Bali cattle fed ration with 20% lamtoro leaf supplementation. The level of lamtoro leaf supplementation in the ration did not affect the digestibility of dry matter, organic matter, and crude fiber. It was concluded that the supplementation of lamtoro leaf in the ration could increase dry matter, organic matter, and crude protein intakes. Addition of 20% lamtoro leaf gave the best effect on the increased body weight gain and feed efficiency in Bali cattle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
