Abstract: An experiment was conducted to determine the effect of including Monechma ciliatum (MC) in the diet of sheep at 0 (control), 10, 20 and 30% levels. The results show that increasing the level of supplementation of MC beyond 20% decreased the feed intake and subsequently live weight gain. Except for total ash, nutrients digestibility follow similar pattern. The least cost of feed per kg live weight gain of $2.04 occurred at the 20% inclusion level and cheapest ration to feed to sheep. Whereas blood parameters differed between treatments, they were mostly within physiological limits. The metabolizable energy content of 2435 kcal/kg of the 20% diet is also the highest amongst all treatments.
