Oa. Awolaja et al., TRACE-ELEMENT LEVELS IN PLASMA SERUM AND ERYTHROCYTES OF KETEKU AND WHITE-FULANI CATTLE/, Tropical Animal Health and Production, 29(1), 1997, pp. 2-6
In order to determine the probable role of trace elements in the maint
enance of trypanotolerance in tropical cattle, the levels of zinc (Zn)
, copper (Cu), manganese (Mn) and iron (Fe) in plasma/serum and erythr
ocytes of trypanotolerant Keteku (Kt) and trypanosusceptible White Ful
ani (WF) cattle were measured by atomic absorption spectrophotometry (
AAS) and compared by breed or sex. Trypanotolerance was associated wit
h significantly higher (P < 0.05) erythrocyte levels of Zn and Mn. The
Kt breed showed higher erythrocyte levels of Zn and Mn than the WF. S
erum Mn level was also significantly higher (P < 0.01) in Kt than WF c
attle. However, PCV and total protein concentration were not significa
ntly different by breed or sex.
