Judul: Pemberian Wafer Suplemen Pakan Mengandung Daun Lamtoro (Leucaena leucocephala) untuk Meningkatkan Performa Domba Lokal
Abstrak: Produksi hijauan untuk ternak ruminansia berfluktuatif dan bergantung pada musim. Pemberian hijauan saja tidak cukup untuk meningkatkan produktivitas ternak, maka wafer suplemen pakan adalah salah satu alternatif. Penelitian ini bertujuan untuk meningkatkan performa domba lokal dengan pemberian wafer suplemen pakan. Penelitian ini menggunakan 12 ekor domba lokal dengan rataan bobot badan 24.54±10.51 kg, menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 3 kelompok sebagai ulangan. Perlakuan terdiri dari P0 = ransum basal + 0% wafer suplemen pakan (kontrol); P1 = ransum basal + 5% wafer suplemen pakan; P2 = ransum basal + 10% wafer suplemen pakan; P3 = ransum basal + 15% wafer suplemen pakan. Parameter yang diukur adalah konsumsi bahan kering, konsumsi protein kasar, pertambahan bobot badan harian, konversi pakan, dan Income Over Feed Cost (IOFC). Hasil penelitian menunjukkan bahwa konsumsi bahan kering, konsumsi protein kasar, pertambahan bobot badan harian, konversi pakan dan IOFC nyata (p<0.05) dipengaruhi oleh perlakuan. Pemberian wafer suplemen pakan hingga level 15% mampu meningkatkan performa domba lokal.

Abstrak: Feed is an important aspect for productivity of livestock. Low quality feed can reduce the productivity of the livestock, so wafer of fed supplement is one of alternative. Wafer lamtoro supplement is one of the feed processing products that have high nutritional value that can help increase the production of livestock. This research aimed to assess the effect of wafer fed supplement on nutrient consumption and digestibility of local sheep rations. This research used Randomized Block Design with 4 treatments and 3 blocks as replicate and used 12 heads of local sheep with initial body weight 24.54±10.51 kg. Treatments were P0 = basal diet + 0% wafer of feed supplement (control); P1 = basal diet + 5% wafer of feed supplement; P2 = basal diet + 10% wafer of feed supplement; P3 = basal diet + 15% wafer of feed supplement. The Results showed that wafer fed supplement had significantly effect (p<0.05) for nutrient consumption, crude protein digestibility, final body weight and feed efficiency but not significant for dry matter digestibility, organic matter digestibility and crude fiber digestibility

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
