Sažetak
Haematological printers and indices as well as plasma lipids (cholesterol and triglyceride) levels were studied in trypanotolerant N’Dama and trypanosusceptible White Fulani (Zebu) cattle raised in the same environment in order to determine the probable role of plasma lipids levels in the phenomenon of trypanotolerance in tropical cattle. The haematological parameters and indices, such as PCV, Hb concentration, RBC, WBC counts, MCV and MCH, showed no significant differences (P>0.05) between the two cattle breeds or sex. N’Dama cattle had significantly lower levels of plasma cholesterol (P<0.05) and triglycerides (P<0.01) than Fulani cattle. Male N’Dama cattle had significantly higher plasma cholesterol levels than females. While no significant gender difference (P>0.05) was observed in plasma triglyceride levels in N’Dama cattle, a significantly higher (P<0.012) plasma triglyceride level was recorded in female White Fulani cattle than in their male counterparts. The findings in this study suggest a possible correlation between plasma lipid levels and trypanotolerance or susceptibility between N’Dama and White Fulani cattle. The roles of plasma lipids in trypanosome growth and differentiation, as well as in the pathology of the disease in the host, are discussed.
