Haematological Profiles of Olive Baboon, Indian Langur and Hamadryan Baboon in Dhaka Zoo

Haematological parameters with regards to sex and species in Olive baboon (Papio anubis), Indian langur (Presbytis entellus) and Hamadryan baboon (Papio hamadryas) was studied to establish a diagnostic indices for the primates species. The values were obtained from 18 healthy animals of these species in Dhaka Zoo. All the animals were divided into three groups on the basis of species, and categorized into two groups (male and female) on the basis of sex. Sex and species significantly affected the values of TEC, TLC, Hb, PCV, MCV and MCHC among these three different species of primates. Among the three male primates species, Olive baboon, Indian langur and Hamadryan baboon, TEC values was higher in Olive baboon (5.3±0.29 x 106 /µl) compared to others, TLC values was higher in Hamadryan baboon (15±0.89x 103 /µl), Hematocrit/PCV was higher in Olive baboon (45±1.9) % and Hb (12.9±0.46 g/dl) was higher in Olive baboon. The average values of RBC among the three female primates species, Olive baboon, Indian langur and Hamadryan baboon, range from 3.62 x 106 /µl to 4.48 x 106 /µl. The average values of RBC differ significantly between the sexes (P ≤ 0.05). Hb % was 10.46 g/dl to 12.16 g/dl and the values differ significantly between the sexes (P ≤ 0.05). WBC values vary significantly between the two populations (male and female), the percentage of lymphocytes was 57 to 66 % and neutrophils were over 38 to 42% in three species. For eosinophil, monocytes and basophil count, no significant differences were found between the male and female. MCV of male Hamadryan baboon was the highest (85%) compared to the Olive baboon, Indian langur and MCHC values was almost same. MCV of female Hamadryan baboon was the highest (80%) compared to the Olive baboon, Indian langur and MCHC values was almost same. There are no significant differences in between the male and female MCHC values of Olive baboon, Indian langur and Hamadryan baboon.
