The present study aims at the evaluation of haematological and cytomorphometrical parameters of naked neck chicken being maintained at Central Poultry Development Organisation, Eastern Region, Bhubaneswar, Odisha. For haematological analysis, a total of five age groups (4th, 7th, 8th, 25th and 60th weeks) and for morphometry of blood cells, 2nd week individuals along with others are also considered. Haemoglobin and total erythrocyte count in adult birds are significantly (p < 0.01) different from other such groups. Irrespective of all age groups, haematocrit differs significantly at p < 0.01. Mean corpuscular volume differs at p < 0.01 between and among groups, except, 7th, 8th and 25th week. In case of mean corpuscular haemoglobin, no difference is observed in 4th and 7th week age and except adults, others do not show significant difference with respect to their sex. Mean corpuscular haemoglobin concentration is not significantly different among or between chicks and adults. Total leukocyte count reflects significant difference (p < 0.01) between and among the age-groups. But, monocytes and heterophils reflect significant difference (p < 0.01) with respect to different ages. Unlike basophils, all other blood cells reflect significant difference (p < 0.01) with respect to age and sexual dimorphism.
