Blood Values from Wild and Rehabilitating Antillean Manatees (Trichechus Manatus Manatus) from Puerto Rico
Western Illinois University 1-75. 13 tables. 13 figures. 2011.
–ABSTRACT: Antillean manatees (Trichechus manatus manatus) are endangered aquatic mammals found in fragmented populations from eastern Mexico through Central America to northern and eastern South America, and the Greater Antilles. All manatees are subject to a variety of anthropogenic threats and are considered a vulnerable species throughout the world. Blood values are an important tool in evaluating the health of free-ranging and rescued manatees part of ongoing conservation efforts. The purpose of this study was to establish preliminary normal ranges of serum chemistry and hematology parameters in healthy Antillean manatees from Puerto Rico. In addition, the research goal was to determine significant variations by age class and sex between free-ranging manatees and those undergoing rehabilitation. Values were obtained from 41 free-ranging, apparently healthy, manatees between 1992 and 2005 during captures for health assessment and from 7 rescued manatees in rehabilitation at the Puerto Rico Manatee Conservation Center. Values included a complete blood count (RBC count, hemoglobin, hematocrit, MCV, MCH, MCHC, RDW, platelets, WBC count, lymphocytes, monocytes, eosinophlils, basophils, and heterophils) and a blood chemistry panel (Liver associated enzymes [ALT, AST, ALP, total bilirubin], kidney, musclue and pancratic associates enzyme and products [CPK, LDH, BUN, creatinine, and BUN and creatinine ratio, uric acid, amylase], glucose and lipids [glucose, triglycerides, cholesterol], proteins [total protein, albumin, albumin and globulin ratio], and electrolytes [sodium, chloride, potassium, phosphorus, calcium, CO sub(2), anion gap]. No significant differences in CPK, LDH, BUN, creatinine, uric acid, and amylase were found among calf, subadult, or adult age classes. Compared to free-ranging adult manatees, wild calves had significantly lower mean concentrations of chloride, sodium, potassium, anion gap, glucose, total protein, albumin, and ALT. Captive calves had significantly higher mean values of CO sub(2), phosphorus, cholesterol, and ALP than free-ranging manatees. Differences in the environments of these two groups, including diet, air and water temperature, water salinity, and stress, might account for some of these results. The lower CO sub(2) and higher anion gap concentrations in adult free-ranging manatees were probably due to greater exertion during capture. AST and ALP were higher in adult free-ranging females than in adult males. Hematological values presented herein will be useful for documenting the typical blood value ranges exhibited by the Puerto Rican population of Antillean manatees and provide a reference for evaluating the health of wild and rescued manatees.
