Response of etawa dairy goat to provision of probiotics in ration containing by-product of palm oil industry

Abstract

The aim of this study was determining the effect of probiotic supplementation on the characteristics of rumen fluid and quality of milk of etawa dairy goat which was given mixed rations of palm oil industry by-product, namely Palm Kernel Cake (PKC), Palm Oil Sludge (POS) and Palm Fiber (PF). This study used Completely Randomized Design (CRD) and consisted of three phases research. Phase I was 4 concentrate treatment rations formulated from various mixture of palm oil industry by-product (PKC, POS and PF) and 5 replications. Best ration of Phase I was continued to supplementation of probiotics (Research Phase II), namely: A) 75g, B) 100g, B) 125 g, and D) 150 g. Parameters measured from Phase II were rumen's fluid characteristics (pH, VFA, NH3-N, and rumen microbes). Research Phase III was biological test of Etawa Dairy Goat (ECDG) with 5 treatment rations and 4 replications. The treatment rations of Phase III were as follows: 1) A = 100% Basal Ration (BR) + 0% Ration of Palm Oil Industry Byproduct (RPalm), 2) B = 75% (BR) + 25% (RPalm), 3) C = 50% (BR) + 50% (RPalm), 4) D = 25% (BR) + 75% (RPalm), and 5) E = 0% (BR) + 100% (RPalm). Parameter of Phase III is milk quality (protein, fat, solid non fat and lactose of milk). The results of this study showed that rumen fluid characteristics and milk quality are in normal range. Probiotics and by-product of palm oil can be used as a feedstuff of etawa crossbred dairy goats.
