Abstract:
Thymus in Kadaknath and Narmada Nidhi breeds of birds under study, was found to consist of 5-6 paired lobes on each side of the neck. Colour of thymus varied amongst the birds of both the breeds. On an average, the gross biometrical values for weight and thickness of thymic lobes in Narmada Nidhi birds were found to be higher in each age group under study. In both the breeds, the thymic lobes did not show decrease in size grossly with the increase in age which may be attributed to increased deposition of adipose tissue. The gross biometrical values indicated significant (p<0.05) variation in each age group amongst the two breeds which might be due to breed difference.
