Abstract:
A total one ninety two day old chick of CARIBRO Vishal broiler chicken were housed in multi-tier brooder cages up to five weeks of age and reared under uniform husbandry conditions. On 36th day divided into 6 groups with three treatments (32 birds in each group’s) including control, enhancer and inhibitor, receiving normal saline, glutamine @ 0.75 mg kg-1 BW and quercetin @5 mg kg-1 BW respectively. After, 24 hours of administration each of the six groups were again divided into two with three groups in each, one being exposed to acute heat stress (40±1 °C; 55% RH) for different duration of 0, 2, 5 and 10 hours in psychometric chamber and another one were kept as unexposed to heat stress. The result indicated that concentrations of lipase (91.88 ± 2.25), amylase (111.49 ± 3.06), pepsin (71.66 ± 1.33) and trypsin (85.10 ± 2.84) were significantly (*p<0.05) higher in enhancer group. Heat stress has significantly (*p<0.05) increased the activity of trypsin (71.96 ± 2.98) and pepsin (61.01 ± 1.88) in jejunum and simultaneously decreased the amylase activity; however the lipase activity did not show any change in response to acute heat stress exposure. A significant difference observed (*p<0.05) on enzymatic activity of pepsin and trypsin and the activity of amylase and lipase was not significant under different duration of heat stress exposure. It can be concluded that protein synthesis modulator; glutamine significantly increases digestive enzymes activity and improve performance of broiler chicken under acute heat stress condition.
