摘要: Abstract The effect of dietary supplementation with fresh Acacia karroo on experimental haemonchosis was determined in 4-month-old castrated Xhosa lop-eared kids. goats were randomly allotted into four treatment groups: non infected, supplemented (NINS); (INS); (IS) and (NIS). Each group contained six goats. goat the infected groups exposed to a single dose 6000 freshly cultured L3 Haemonchus contortus larvae. kids received 182 g/day (on DM basis) A. leaves, constituting 50% their diet. Blood samples collected every two weeks determine haematology serum enzyme concentrations. At end experiment at day 60, all humanely slaughtered worm burdens. A significant decrease faecal larval counts (FLC) observed IS as infection progressed while it continually increased INS after Week 4 infection. necropsy, had significantly ( P leaves reduced level subsequently leakage enzymes blood.
