The feeding trial was carried out for 90 days in which the
feed intake and live weight changes were measured. Twenty-
five sheep selected for the study were weighed and divided
into five different weight groups, which represent the
replications or blocks of the experiment using randomized
complete block design. All animals from each block were
allocated to the experimental feeds at random. Five treatment
diets were formulated by mixing Napier grass with 100, 200,
300 and 400 g/kg DM basis of Sesbania and Napier grass
alone as control treatment. The feed mixtures were offered to
individual animals ad lib two times a day at 0800 and 1400 h.
Refusals were collected and weighed every morning to obtain
an estimate of intake. Daily record of feed intake was
maintained throughout the experiment. Samples of refusal
collected from individual animals every day were pooled over
the entire experimental period and sub-sampled for analysis.
Experimental animals were weighed on the first day of the
feeding trial and subsequently at weekly intervals before
offering the morning feed on the same day of the week after
withholding feed and water overnight. The average daily body
weight gain (ADWG) during the experimental period was
calculated by regressing body weight of each animal on num-
ber of days of feeding.
