Comparing Chick and Grower Stages of Nine Breeds of Gallus gallus domesticus, Linnaeus, 1758 for RBC and WBC Parameters

Abstract The present study estimates haematological parameters of different breeds of chicken, viz., Aseel, Black Rock, Dahlem Red, Kadaknath, Naked-neck, Red Cornish, Rhode Island Red, Vanaraja and White Leghorn. Blood samples were collected from 40 unsexed birds of each breed, comprising 20 chicks (< 2 months) and 20 growers (2-8months). Erythrocytic parameters such as Haemoglobin, Total Erythrocyte Count, Packed Cell Volume and erythrocyte indices and leukocytic parameters such as Total Leukocyte Count and Differential Leukocyte Count were taken into account. The data were subjected to ANOVA followed by post-hoc analysis and significant differences were observed at p < 0.01 and p < 0.05. As a whole, Red Blood Cell and White Blood Cell parameters (except Total Leukocyte Count and Basophil percentage which are not significantly different) record significant differences at p < 0.01 among and between the breeds. But some birds also differ at p < 0.05 among and between themselves.
