| dc.description.abstract | An experiment was carried out with 288 straight-run broiler chicks (Cobb 500)
using different litter materials (treated and untreated) to compare the production
performance of broiler at 28 days. The experimental unit were assigned to 6 dietary
treatments i.e.T1, T2, T3, T4, T5 and T6 among which T1, T3 and T5 were treated
group (treated with aluminum sulfate i.e. alum) and T2, T4 and T6 were untreated
group. Each treatment had 4 replications with 12 birds each. The live weight was
statistically significant at 4
week of age. The highest live weight was attained at
the birds of treatment group T1 at 4
th
week of age. Feed consumption per bird were
highest in the treatment group T4 and lowest on the birds of treatment group T1 at
4
th
th
week of age. Feed conversion ratio showed significantly different. The higher
feed efficiency value (1.61) was recorded in treatment T5 whereas lower (1.83) in
treatment T6. The survivability percentages of broilers at different treatment group
were statistically non-significant. The value of pH and ammonia are related to each
other. By increasing the value of ammonia increased the value of pH. Higher pH
and ammonia value was found in untreated groups. The cost of litter per bird and
cost of litter per kg live weight gain differed from each other. It is evident from the
study that rice straw was more economic than saw dust and rice husk. From the
above findings it might be concluded that the performances of broiler are more or
less similar but rice straw was economic among the types studied followed by saw
dust and rice husk. | en_US |
