Performa Sapi Pedaging yang Diberi Ransum Mengandung Limbah Sawit (Kajian Kuantitatif)

Abstract

Penelitian ini bertujuan untuk mengkaji secara kuantitatif performa sapi pedaging yang diberi ransum mengandung limbah kelapa sawit (pelepah sawit, bungkil sawit, dan kombinasinya). Penelitian dilakukan melalui kajian kuantitatif berdasarkan artikel penelitian yang dipublikasi di jurnal ilmiah. Pengumpulan data yang diperlukan, diperoleh dari 10 jurnal terakreditasi nasional dan 4 jurnal internasional bereputasi. Analisis yang dilakukan terhadap data yang diperoleh adalah perhitungan persamaan regresi linier, perhitungan persamaan regresi nonlinier sederhana, dan perhitungan koefisien determinasi (R2 ). Hasil penelitian menunjukkan bahwa penambahan pelepah sawit pada ransum sapi meningkatkan pertambahan bobot badan (PBB) dan regresi yang signifikan (P<0,05) . Nilai kecernaan pelepah sawit masih pada rentang kecernaan yang baik. Level pemberian optimum pelepah sawit yaitu 39,84% dalam meningkatkan PBB sapi. Pemberian bungkil sawit pada ransum sapi juga meningkatkan PBB dengan nilai regresi yang sangat signifikan (P<0,01), dan level optimum pemberian sebesar 13,98%. Namun demikian, peningkatan level pemberian bungkil sawit dapat meningkatkan konsumsi PK dan KcPK. Penambahan kombinasi pelepah sawit dan bungkil sawit memperlihatkan hasil regresi tidak signifikan terhadap PBB sapi (P>0,10).

This study aims to assess quantitatively the performance of beef cattle fed a ration containing palm oil waste (palm frond, oil palm cake, and their combination). The research was conducted through quantitative studies based on research articles published in scientific journals. The required data collection was obtained from 10 nationally accredited journals and 4 reputable international journals. The analysis carried out on the data obtained is the calculation of the linear regression equation, the calculation of nonlinear regression, and the calculation of the coefficient of determination (R2 ). The results showed that the addition of palm fronds to the cattle ration increased body weight gain and had a significant regression (P<0.05). The digestibility value of the palm fronds is still in a good digestibility range. The optimum level of palm fronds giving was 39.84% in increasing body weight gain of cattle. Oil palm meal on cattle rations also increased body weight gain with a very significant regression value (P<0.01), and the optimum level of giving oil palm meal was 13.98%. Increasing the level of oil palm meal can increase the consumption of crude protein and crude protein digestibility. The addition of a combination of palm fronds and oil palm meal showed a not significant regression results for body weight gain of cattle (P>0.10).
