The objective of this study was to determine effect of using treated sugarcane bagasse as roughage source of TMR on the utilization of nutrients and performance of dairy heifers. Twelve crossbred 98% HF blood heifers (175±20 kg.BW) was assigned to randomized completed block design (RCBD) The treatments were following as different NaOH level of treated sugarcane bagasse 0, 2, 4 and 6% and all of TMR was formulated to similar TDN and CP (65% and 12.5%). The results showed that the heifers fed treated sugarcane bagasse quality with 4% NaOH had better DMI, DMIBW and FCR than others, especially, the highest ADG in 4% (P<0.01). It is therefore can be concluded that the optimal level of NaOH to enhance treated sugarcane bagasse was 4% would improve growth rate... |
