Summary
An experiment was carried out in order to evaluate effects of feed supplementation to crossbred laying hen under the rural condition of Bangladesh on egg production and quality. Seventy-two laying hens (male Rhode Island Red x female Fayoumi) were distributed among 18 farmers. Each farmer received 4 birds and each bird was allocated to each treatment. The treatments were: ad libitum feed (120 g) with intensive condition (T1), 60 g feed supplementation with scavenging condition (T2), 30 g feed supplementation with scavenging condition (T3) and fully scavenging without supplementation (T4).

| Significant differences were found in egg production and egg quality traits. Egg production was significantly higher in T1 than in the other treatments (P<0.01). But no significant differences were found between T3 and T4 (P>0.05). Similar results were found in shell colour. Again, Egg weight was significantly higher in T1 than other treatments and the lowest value in T4 (P<0.01). No significant difference was found between T2 and T3 (P>0.05). Opposite result was found in yolk colour, where yolk colour was significantly lighter in T1 but darker in T4 (P<0.01). However, no significant differences were found between T2 and T3 in yolk colour (P>0.05). Albumen height and Haugh unit was significantly higher in T3 and T4 than T1 and T2 (P<0.01). No significant differences were found between T3 and T4 and T1 and T2 (P>0.05). The shell thickness and body weight gain during experimental period shown the same pattern being significantly higher in ad libitum group than scavenging birds (P<0.05). No significant differences were found between scavenging birds (P>0.05). Profit was higher in T4, but considering one-year laying period the T2 treatment may be more profitable. Present results indicate that at least 60 g of feed supplementation needed for the scavenging crossbred birds for viable production. However, the amount of supplementation is also dependent on location, that is availability of feed resources around the farmer's house. Better economic condition of farmer and enough feed resources around farmer's house may need lower amount of supplementation. |
