| dc.description.abstract | The research work was carried out on performance of sonali chicken through feed
supplementation under scavenging condition at Haluagram village in Sunamganj district of
Sylhet, Bangladesh. Hundred sonali hens (♂Rhode Island Red x ♀ Fayoumi) were distributed
among 20 farmers at 15 weeks of age. Four different treatments were given in four different level
of feed supplementation of rice. In each treatment consist of five farmers. Control (T0) was no
supplementary feed, treatment 1 (T1) was 30 g supplementary feed, treatment 2 (T2) was 60 g
supplementary feed, treatment 3 (T3) was 100 g supplementary feed with scavenging. Body
weight and weight gain were significantly higher in T3 than the others. Similarly total body
weight gain was significantly (P<0.05) higher in T3 treatments and lower in T0. Again, Significant
differences (P<0.05) were found in body weight at 34 weeks. In laying period body weight was
significantly higher in T3 than the other treatments and lowest in T1. In case of feed conversion
ratio was no significant differences among the different treatments. The egg production was no
significant differences among the different treatments. Though the egg production of control
group was also lower. The egg weight was significantly higher in T3 than other treatments and the
lowest value in T0. But similar egg weights were found between T1 and T3. High mortality
percentage was found in T0 but lower in T1 during growing period. But similar mortality
percentage were T2 and T3. During study period the laying was higher mortality percentage in T2
and lower was T1 and T3. The farmers were more benefited by the 30g supplementation compare
to the others. Present results also indicate that at least 30 g of available feed supplementation
needed for the scavenging crossbred birds for viable egg production, good feed conversion ratio
and more profitable, because the scavenging feed is also dependent on available feed resources
around the farmer’s house of hoar areas. | en_US |
