| dc.description.abstract | The dietary effect of levu cell, a commercial probiotic on the broiler growth, meat yield
and economics of production was studied for the period of 35 days. A total of One
hundred twenty unsexed day-old commercial broiler chicks (Hubberd classic) were
randomly divided into four dietary treatments having 3 replications in each treatment.
The number of birds in each treatment was 30 while in each replicate 10. The birds were
fed probiotic (levu cell) at dietary levels of To(0g), T:1(0.5g), T2(1.0g) and T3(1.5g) per
kg of mixed feed. The body weight gain of different treatment groups ware as
T0(1196.28g), T:1(1186.88g), T2(1251.58g) and T3(1273.41g).Feed intake of different
groups were 1T0(2388.4g), T:(2446.15g), T2(2484.90g) and T3(2502.80g) and feed
conversion ratio of different group were To(1.99), T:(2.06), T2(1.98) and T3(1.96). A
little improvement was observed in body weight gain of broiler chicks at 35 days for
T2(1251.58g) and T3(1273.41g) groups, although body weight gain, feed intake and feed
conversion of broilers did not differ significantly (P>0.05) compared to control group.
The abdominal fat weight of different group were To(1.11%), T:1(1.14%), T2(1.0%) and
Ts (1.0%). The supplementation of probiotic in broiler diets was effective in reducing
abdominal fat deposition (P<0.05) but had no significant effect on other meat yield
parameters of broilers. The addition of probiotic in the diet of broilers at the levels
studied could not aid in economizing broiler production. It was concluded that probiotic
could not show beneficial effects on performance of broilers at the level tested but was
effective in reducing abdominal fat. | en_US |
