Effect of Dietary Supplementation Based on Ammoniated Palm Frond with Saccharomyces cerevisiae and Gambier Leaves Waste on Nutrient Intake and Digestibility, Daily Gain and Methane Production of Simmental Cattle

The objective of this study were to evaluate the effect of supplementation of Saccharomyces cerevisiae (SC) and Gambier Leaves Waste (GLW) in the diet of ammoniated palm frond (APF) based on nutrient digestibility, growth performance and methane production of Simmental cattle. Experimental design used is a Latin Square Design (LSD) with four treatments and four periods. This experiment used 175-200 kg male Simmental cattle. Cattle were fed a basal diet containing (dry matter basis) 40% APF and 60% concentrate. The treatments were (A) 40% APF + 60% concentrate + mineral S and P, (B) A + SC, (C) A + GLW, and (D) A + SC + GLW. The results showed that the DM, OM, ADF, NDF, and cellulose digestibility of D were significantly (P<0.05) higher than A. There had no significantly (P>0.05) difference among treatments on CP digestibility, nutrient intake, and urine allantoin. Supplementation of SC + GLW was able to improve body weight gain (1.22 kg/head) and reduce methane gas production up to 57 % compared to control. It can be concluded that supplementation with SC + GLW generates the best result in nutrient digestibility, daily gain, and reduce methane gas production of Simmental cattle.
