<![CDATA[This study aimed to determine the effect of adding fermented seaweed Eucheuma cottonii in concentrate on intake and digestibility of dry matter, organic matter and crude fiber in heifers fed a combination of kume grass silage and corn fodder. The study used four Bali heifers with an average body weight of 133.4 kg, using a Latin Square Design (LSD) with 4 periods and 4 treatments based on percentage. E. cottonii in the concentrate was: 5% (R1), 10% (R2), 15% (R3), and 20% (R4). The data were analyzed using analysis of variance (ANOVA) and Duncan's multiple range test. The results of the variance analysis showed that the addition of Eucheuma cottonii seaweed in the concentrate had no significant effect (P>0.05) on dry matter intake, organic matter intake, and dry matter digestibility, organic matter digestibility, and crude fiber digestibility. However, it had a significant effect (P<0.05) on crude fiber intake. The conclusion of this study is that the addition of concentrate containing fermented Eucheuma cottonii did not increase dry matter, organic matter, and crude fiber intake and digestibility but decreased crude fiber intake in Bali heifers consuming a combination of kume grass silage and corn fodder.]]>
