Supplementation of Saccharomyces cerevisiae and Sapindus rarak in Diet Based of Oil Palm Frond (OPF) on Nutrient Digestibility and Daily Weight Gain of Goat

This experiment was to study the effect of adding Saccharomyces cerevisiae and Sapindus rarak in diet Oil Palm Frond (OPF) based of nutrients digestibility and body weight gain of goats.Experimental desiegn used randomized blok design, with 4 treatments and 4 groups as replications.This experiment used six teen ettawa goats (40±8.5 kg liveweight).The four treatments were (A) native grass+concentrate (B), OPF (previously treated with 6% urea)+concentrate, (C) Diet B+1% Saccharomyces cerevisae and (D) Diet C+4% Sapindus rarak.The animals were adjusted to their treatments over a 2 week preliminary period which was followed by an 8 week experimental period.Feed intake was determined daily and live weight was measured every two week.Digestibility was measured by total faecal collection over 6 consecutive days on last week of experiment period.The results showed that the dry matter digestibility of treatment B (50.74%) were significantly lower than treatments A, C and D respectively (67.37, 62.38 and 65.71%) and supplementation of Saccharomyces cerevisiae was able to improve nutrient digestibility and body weight gain of goat, but still low compared to control (A).Addition of 4% Sapindus rarak in treatment D (123 g dayG 1 ) was able to provide digestibility and body weight gain similar to the control ration (132 g dayG 1 ).It can be concluded that the use of OPD as a substitute for grass in goat diets would give the same results with the grass when added 1% Saccharomyces cerevisiae and 4% Sapindus rarak.
