【 摘 要 】

An experiment was conducted to evaluate feeding of total mixed ration (TMR) on the productivity of Friesian Holstein (FH) male cross-grade cattle at Semarang Municipality. TMR was a ration formulated with agricultural and agro-industrial by-product (no grass and/or green forage were used) to fulfilled the nutrient requirement of beef cattle. Total mixed ration were formulated on iso-energy of 66% of total digestible nutrients (TDN) and different level of crude protein (CP) content of 11%, 12%, 13%, and 14%. Twenty (20) heads of FH male cross-grade cattle with initial body weight of 292.40+33.06 kg were used in this experiment, and were arranged into 5 treatments T0, T1, T2, T3, and T4), and 4 replications. Data collected were analysed statistically using analyses of variance (Anova) based on the completely randomized design (CRD), then followed by Duncan's Multiple Range Test (DMRT) for different among treatments. Results of the experiment showed significantly different effect (P0.05) on feed conversion ratio (FCR), and feed efficiency. Others parameter showed that there were no significantly different (P>0.05) effect on the dry matter and organic matter digestibility in vitro, rumen ammonia concentration, and volatile fatty acid's rumen concentration. It was concluded that feeding TMR was potentially prospected for fattening of beef cattle, particularly as feeding strategy when there was no grass and/or green forage anymore.
