The role of management systems on Haematological profile of Southern
giant pouched rat (Cricetomys ansorgei) under the tropical setting in
Morogoro, Tanzania
Abstract
Introduction: The study explored the effect of management system on the
haematological profiles of African giant pouched rats (Cricetomys
ansorgei) as compared to the natural environment standard procedures
were observed in determining haematological parameters. Method: The
blood samples were collected from the rats both wild and captivity rats,
analyzed using statistically the descriptive statistics and analysis of
variance were done using SPSS version 20. Results: The southern giant
pouched rats in the wild had higher counts (mean ± standard deviation)
for RBC (6.5±1.5) and lymphocytes (38.1±15.7) than housed rats. The rats
in captivity had high reading of total white blood cell counts
(8.7±2.4), neutrophils (3.5±2.4) and eosinophil (1.4±1.01) than the wild
rats. The blood indices showed that wild rats have relatively higher
reading on PCV (42.1±7.4) and HBC (18.5±1.8); whereas the rats in
captivity had high reading on MCV (72.9±6.7), Thrombin concentration
(380.2±104.5) and MPV (7.6±0.9). The determination of sex versus blood
cells and indices; it was shown that female wild rats had high reading
on RBC (7.2±1.3), WBC (7.8±1.7) and lymphocytes (35.0±1.8) compared to
males; the male rats had high reading on monocytes (3.3±1.9),
neutrophils (2.3±1.3) and eosinophil (1.0±0.5). The relation of sex to
the determined heamotological parameters had no significant difference.
The blood indices with respect to se of the rats; it was shown that wild
male rats had high reading on MCV (67.0±18.8), PCV (39.8±9.6), HBC
(14.9±4.4) and thrombin concentration (387.0±109.0); meanwhile the rats
in captivity the reading were not significant different. Conclusion: The
present study presents preliminary haematological profiles of southern
giant pouched rats in Morogoro which could be useful to researchers in
animal physiology. The authors are adamant that these findings provide
an insight on further research areas for laboratory based animals and
studies on human parameters involving rats or mine in the tropics
