Abstract:

Environmental stress causes structural changes in adrenal gland. Therefore the present study was undertaken to evaluate the histomorphology of adrenal gland in broiler chicken subjected to cold stress and its various ameliorating remedies. 270 day-old commercial broiler chicks were used for the study. The chicks were distributed into 7 treatments of 3 replicates with 13 chicks each. Cold stress was provided at 2°C to 8°C for 8 hours from 3rd to 6th week of age in all treatment groups except first and fifth treatment groups. The broiler birds in T1 and T5 were reared under normal temperature conditions (25°C). T1 was kept as control group. Antioxidant vitamin E 250 mg per kg of feed was supplemented to basal diet in T3. Chromium 0.1 gram per kg of feed was supplemented to basal diet in T4. The results revealed that adrenal glands from T1 showed no shift from normal histology. Adrenal gland from T5 group revealed similar histology as in control group. The adrenal gland from T2 group revealed severe hypertrophy of cells. Hyperaemia was also observed on histological examination. There was severe depletion of lipid content in cortical cells. There was also seen severe distortion of architecture of adrenal cells. The adrenal gland from T3 group revealed mild changes in terms of hyperaemia and hypertrophy of cells. T4 group showed moderate changes in adrenal gland on histological examination. T7 group revealed mild changes in terms of hyperaemia, hypertrophy of cells and lipid depletion in cortical cells. T6 group also showed mild changes. In conclusion, the cold stress mitigating remedies such as early cold conditioning, supplementation of vitamin E or chromium reduced the pathological effects of cold stress in this organ.
