Haematological profile of Khillar breed of cattle in Karnataka

Aim: The present study was undertaken with the objective of determining the reference values for hematological parameters for Khillar breed of cattle in general and in the subpopulations such as male, female and different age group of animals. Materials and Methods: The present study was carried out at Khillar Cattle Breeding Farm, Bankapur, Karnataka. A total of sixty eight animals were used in the study. Animals were grouped based on sex into male and female and in the age groups 3-5 years, 6-10 years and above 10 years of age. Blood samples with anticoagulant were collected from these animals and hematological parameters were determined. Mean values were compared between males and females, and between different age groups. Results: Mean and standard error values of all the hematological parameters for Khillar breed of cattle in general, male, female and different age groups of animals are tabulated. TEC, TLC, Hb, PCV and PLT values in males were significantly higher than female, whereas there were no significant differences in the mean hematological values between animals in the different age groups. Conclusions: The present study reported the hematological values which could serve as baseline/reference values for Khillar breed in general, male, female and different age groups of Khillar breed of cattle. These reference values help in comparison of normal with various physiological, nutritional and deficiency conditions. Keywords: hematological, Khillar breed, Karnataka, profile.
