Efek Pemberian Pelepah Sawit Yang Difermentasi Dengan Prolinas Terhadap Karakteristik Rumen Sapi Perah PFH

Abstract

The study aimed to determine the effect of prolinas (pineapple skin probiotics) on the rumen fluid characteristic of dairy cows through in vitro method. A Completely Randomized Design with 4 treatments and 4 replications was applied. The treatments consist of A: oil palm fronds without fermentation (control), B: oil palm fronds fermented with prolinas of 2.5% dry matter (DM), C: oil palm fronds fermented with prolinas of 5% DM, D: oil palm fronds fermented with prolinas of 7.5% DM. Parameters measured were dry matter digestibility (DMD) and organic materials digestibility, N-NH3, rumen pH, concentration of volatile fatty acid in the rumen. The results showed that oil palm fronds fermented with prolinas with concentration of 5% DM was the best results in improving DMD and total VFA concentration in the rumen of dairy cows.
