Effect of dietary vitamin C and sodium bicarbonate supplementation on the performance of broiler chicks subjected to heat stress [electronic resource].

Includes reference

The objectives of this investigation was to sfudy the adverse effects of heat stress on performance and some blood plasma constituents of broiler chicks, and to alleviate these adverse effects by supplementation of ViI. C, or S.B. or their mixture by using three hundred 22 - day old Ross broiler chicks. All birds were individually weighed, and randomly assigned to five treatment groups (3 replicates of 20 birds each). The first group was fed a finisher diet (control) and reared under normal temperature (25- 27 °C). The second group was fed a finisher diet and exposed to a daily heat stress period ( 36-37°C ) for 6 hours from 10 a m to 4 pm. Groups from the third to the fifth were exposed to a daily heat stress period (36-37°C) for 6 hours from 10 a m to 4 p m and fed a finisher diet supplemented with 100 mg Vito C / kg diet 1% S.B. or its (100 mg Vito C/ kg diet + 1% S.B.), respectively.
