THE EFFECT OF FEED SUPPLEMENTMULTINUTRIENT SUPPLEMENTATION TO CORN LEAVES SILAGE BASAL DIET ON METHANE PRODUCTION AND PRODUCTIVITY OF PERANAKAN ONGOLE CATTLE

Abstract

The study was undertaken to investigate the effect of FSM supplementation to Corn Leaves Silage (CLS) basal diet fed to Ongole generation (PO/ OG) on methane production and their productivity. The study used 6 OG cattle, were divided into 2 groups, namely Control Group fed by CLS and concentrate, and Treatment Group fed by the same diet offered to the Control group plus FSM. The measurements were undertaken on VFA concentration to estimate the amount of methane produced, feed consumption, feed conversion ratio (FCR) and live weight gain (LWG) of the animals. The results showed that the animals fed by CLS and concentrate had less feed consumption and LWG compared to the animals fed by CLS, concentrate and FSM (5.9 kg and 129 g/day 5 6.3 kg and 398 g/day) (P<0.05). Animals in Treatment Group had better FCR compared to the animals in Control Group (15.9 Ls 45.6 g DM/g LWG) (P<0.05). The proportion of propionate from VFA total produced in the rumen of animals in treatment Group was higher than that produced in the rumen of animals in Control Group (31.47 % Ls 5.53 %), which indicated less methane produced (21.7 mmol) in Treatment group compared to 88.0 mmol in animals in Control Group. It can be concluded that feeding the animals by FSM reduced methane produced from the rumen and increased feed consumption and LWG of the animals.
