In this experiment, 16 Germany mixed bunny (male & female) rabbits of about 2 months of age were
divided into 4 dietary groups comprising of four bunnies in each. The Experiment was divided into 2 phases
and conducted for 91 days. First phase was for 42 day and the second phase for 49 days. In first phase,
animals of first diet group (01) were fed with 40% concentrate HCF plus 60% roughage (80% oat rye grass
kikyu and 20% clover), second diet group (02) consisted of 40% concentrate (20% RB in concentrate
mixture) plus 60% roughage (80% oat or rye grass or kikuyu and 20% clover) of total dry matter required,
third diet group (03) had 40% concentrate (40% RB in concentrate mixture) plus 60% roughage (80% oat,
rye grass, kikuyu, & 20% clover), and diet group 4 (04) consisted 40% concentrate (60% RB in concentrate
mixture) plus 60% green roughs (80% oat, or rye grass or kikuyu, and 20% clover) of total dry matter
required . In second phase, same rabbits from phase 151 were used for 49 day of experimental period.
Animals of first diet group (01) were fed with 40% HCF plus 60% roughage (80% oat or rye grass or kikyu,
and 20% white clover) of total dry matter required. Second diet group (02) consisted· of 40% concentrate
mixture containing 40% RB plus 60% roughage (80% oat or rye grass or kikuyu, and 20% white clover) of
total OM required, third diet group (03) had 50% concentrate mixture containing 40% RB, plus 50 roughage
(80% oat or rye grass or kikuyu, and 20% clover), and diet group 4 (D4) consisted of 60% roughage (80%
oat or rye grass or kikuyu, and 20% white clover). A digestibility trial for 7 day was carried out at the end of
the experiment. Daily feed intake, and urine and faeces excreted by the animals were recorded. Body weight
change was recorded at 7 day interval. In first phase the average daily weight gain was not significantly
different (p>0.05) between diet groups. Growth performance of o1 and 0 4 was almost similar which
indicated that inclusion of rice bran @ 60% in concentrate mixture is possible. Economically, D4 had
highest economic return and net income was in increasing order as the level of RB in concentrate was
increase (20, 40 and 60%). In second phase, the average daily weight gain was highest in 04 which contains
60% co~centrate .<Of 40% RB) that was superior to produce more meat them other dietary group. Feed
conversiOn . Ratio was better for diet 4 and was in decreasing order to Diet3 and diet l of 7.87, 8.49 and
?.14 respectively. Economically, among the tested feed, diet group 4 recorded significantly highest net
mcome ofRs 73.99 and lowest with diet group 1 (55.37±4.88) during the experiment period of 49 days.
