Pengaruh Pakan Komplit Berbahan Lamtoro dan Silase Campuran terhadap Nilai Teknis Ransum Sapi Bali Penggemukan

The Effect of Complete Feed Made from Lamtoro and Mixed Silage on the Technical Value of Fattening Male Bali Catlle Ration

Abstract

Pola penyediaan pakan dalam usaha peternakan rakyat merupakan masalah utama yang perlu untuk dibenahi khususnya pada daerah lahan kering seperti NTT. Kuantitas serta kualitas hijauan merupakan faktor penting dalam menentukan produktivitas ternak. Pakan berfungsi untuk memenuhi kebutuhan ternak baik untuk hidup pokok, pertumbuhan, reproduksi dan produksi. Produksi pakan yang tersedia di alam maupun yang dibudidaya menjadi faktor utama dalam menentukan keberhasilan usaha ternak sapi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan komplit berbahan dasar lamtoro dan silase campuran jerami jagung muda-daun gamal dengan level yang berbeda terhadap nilai konversi ransum, efisiensi penggunaan pakan dan feed cost per gain pada sapi bali jantan penggemukan. Menggunakan 4 ekor sapi bali jantan berumur 1–1,5 tahun, berat badan 148-156 kg dan rataan 152,50 kg.  Penelitian ini menggunakan Rancangan Bujur Sangkar Latin terdiri dari 4 perlakuan dan 4 ulangan. jenis perlakuan yaitu: P₀; lamtoro (kontrol) 100%, P₁; Lamtoro 60% + jerami jagung-legum daun gamal 30% + konsentrat 10%, P₂; lamtoro 50% + jerami jagung-legum daun gamal 40% + konsentrat 10%, P₃; lamtoro 40% + jerami jagung-legum daun gamal 50% + konsentrat 10%. Data dianalisis menggunakan analisis sidik ragam ANOVA. Hasil penelitian menunjukan bahwa rataan konversi ransum P_0; 13,51±2,03, P_1; 13,32±1,77, P_2; 11,68±0,54, P_3; 11,36±0,96, efisiensi penggunaan pakan (%) P_0; 7,51±0,98, P_1; 7,62±1,10, P_2; 8,58±0,41, P_3; 8,86±0,79, feed cost per gain P_0; 24831±3717, P_1; 26695±3772, P_2; 23608±1139, P_3; 23147±2088. Hasil analisis statistik menunjukkan bahwa perlakuan berpengaruh tidak nyata P>0,05. Kesimpulan: pemberian pakan komplit berbahan dasar lamtoro dan silase campuran jerami jagung muda-daun gamal pada level 30-50% signifikan terhadap perlakuan 100% pakan lamtoro terhadap nilai konversi ransum, efisiensi penggunaan pakan dan feed cost per gain Sapi Bali Jantan Penggemukan.

The pattern of providing feed in people's businesses is a major problem that needs to be addressed, especially in dry land areas such as NTT. The quantity and quality of forage are important factors in determining livestock productivity. Feed works to meet the needs of livestock both for basic life, growth, reproduction and production. The production of feed that is available in nature and that is cultivated is a major factor in determining the success of a cattle business. This study aims to determine the effect of providing complete feed made from lamtoro and silage mixture of young corn straw and gamal leaves with a level that is on the value of ration conversion, feed use efficiency and cost per gain in fattening male bali cattle. Using 4 male bali cattle aged 1–1.5 years, body weight 148-156 kg and an average of 152.50 kg. This study used a Latin square design consisting of 4 treatments and 4 replications. type of treatment, namely: P0; lamtoro (control) 100%, P1; Lamtoro 60% + corn straw-legume gamal 30% + concentrate 10%, P2; lamtoro 50% + corn straw-legume gamal 40% + concentrate 10%, P3; lamtoro 40% + corn straw-legume gamal 50% + concentrate 10%. Data analysis used analysis of variance ANOVA. The results showed that the average ration conversion was P0; 13.51±2.03, P1; 13.32±1.77, P2; 11.68±0.54, P3; 11.36±0.96, feed use efficiency (%) P0; 7.51±0.98, P1; 7.62±1.10, P2; 8.58±0.41, P3; 8.86±0.79, feed cost per gain P0; 24831±3717, P1; 26695±3772, P2; 23608±1139, P3; 23147±2088. The results of the analysis showed that the treatment had no significant effect P>0.05. Conclusion: the provision of complete feed made from lamtoro and silage mixture of young corn straw-gamal leaves at the level of 30-50% was significant for the treatment of 100% lamtoro feed on the ration conversion value, efficiency of use and feed cost per gain of Fattening Male Bali Cattle.
