A comparison of field tick infestation on N'Dama, Zebu and N'Dama×Zebu crossbred cattle
Veterinary Parasitology, 1993Tick burdens, estimated from cumulative tick counts, were determined on N'Dama, Zebu and F1 N'Dama x Zebu crossbred cattle. N'Dama showed significantly fewer ticks than the Zebu and F1 cattle (P < 0.001). A previous trypanosomosis infection did not affect tick burdens on the three genotypes.
