in body weight gain between the treatment groups although beef cattle on cassava peel consumed less DM than
other cattle. Nitipot et al. (2004) replaced cassava chip by cassava pulp at a rate of 0, 50,and 100% in the concentrates and fed crossbred Holstein Friesian (>87.5% Holstein Friesian) heifers 2% body weight of concentrate plus ad libitum rice straw. The results showed that rice straw and total DM intake, eating behavior,fiber digestibility, rumen fermentation endproducts,blood metabolite and body weight gain were similar in all treatments. When the data
for milk yield and body weight change were combined, it was possible to compare the effect of different rations on the apparent utilization of NELP intake (Table 5). All cows consumed NELP therefore the partitioning of energy between
milk productions was also similar.
