“…Analysis of WBC found that segmented neutrophils and lymphocyte predominated as in previous reports [2,3,9] . However, we found that monocytes were in higher proportion than eosinophils, which were the same as Dastjerdi [15] reported that monocytes were the main WBC in juvenile elephants.…”

“…However, we found that monocytes were in higher proportion than eosinophils, which were the same as Dastjerdi [15] reported that monocytes were the main WBC in juvenile elephants. This was contrasted with de Mel [9] and Salakij [3] who reported finding more eosinophils than monocytes. The variation of blood parameters of each study might be influent by various of laboratory error such as pre-analytical error; for instance, blood collecting method, blood sample preserving procedure before handing to laboratory, storage period until examination, and sample transportation.…”

“…Most blood parameter data in Asian elephants are based on samples collected from zoo elephants in North America and Europe [8] , where the geographic, climate and management conditions are different from Thailand. There are some data on Asian elephants in range countries; e.g., India [2] and Sri Lanka [9,10] , but there still are considerable differences in geography, where differs in the nutrition, which can lead to different blood parameters [11] . Physical exercise due to work and management, can cause stress between those elephants, which may affect the blood profiles [9,12] .…”

“…Physical exercise due to work and management, can cause stress between those elephants, which may affect the blood profiles [9,12] . Moreover, De Mel [9] found hematological ranges differed across several populations of Asian elephants in Sri Lanka. The aim of this study was to begin establishing a set of hematology and blood chemistry reference intervals for Asian elephant used in tourist camps in Thailand, and other Asian elephant range countries.…”
