“…The coloured broilers normally attain a BW in the range of 1400-1500 g at 42 days of age. Because of their low BW and plumage colour, there is a high demand for coloured broilers in the Indian subcontinent (Bhanja and Mandal 2007). In the present study, the BW of coloured broilers was lower than that reported by Bhanja and Mandal (2007).…”

In the present study, the BW of coloured broilers was lower than that reported by Bhanja and Mandal (2007). This may be due to the handling stress experienced during recording of immunological and haematological parameters or the season of study.…”

The effect of post-hatch (PH) feed deprival for 6, 12, 24 and 36 h was studied in male and female broiler chickens. At 21 d, lower body weight (BW) was recorded in 36 h feed-deprived (FD) birds; however, at 42 d PH, only 36 h FD female birds had lower BW compared to control and other FD birds. Feed intake during 0-21 d PH was lower in 36 h FD birds, but feed conversion ratio did not differ between control and FD birds. The H:L ratio significantly increased in 12-36 h FD male birds and 24-36 h FD females. The humoral immune response was similar in FD and control birds, but the cellular immune response was higher in 12 and 24 h FD female birds. At 36 h the expression of interleukin 6 (IL-6), toll-like receptor-2 (TLR-2) and tumour necrosis factor-α-gene was down-regulated in male birds only. However, the expression of IL-6 and TLR-2 was up-regulated in 12-36 h FD female birds at 7 and 14 d PH. It may be concluded that PH feed deprival for the first 24 h did not affect growth performance but improved immune response in slow-growing broiler females. ARTICLE HISTORY
