RESUMO
Serum protein values were determined in 6 lambs given 1 dose of 200 metacercariae of Fasciola gigantica. Over the 22 weeks of the experiment, total serum protein values in these lambs were only moderately increased over those of control lambs (n = 6). The increase was mainly associated with the change in alpha2-globulin and gamma-globulin fractions. The highest value of gamma-globulin (39.03%) of total serum protein was observed at 18 weeks after infection. Mean albumin concentration in the exposed lambs decreased considerably, starting in week 8 and persisting until the end of the experiment. The lowest level (39.28%) was seen at week 16.

Efficacy of diamphenethide ("Coriban", Burroughs Wellcome) and rafoxanide ("Ranide", Merck Sharpe & Dohme, Ltd.) was evaluated in lambs against 8-week old experimentally induced Fasciola gigantica infection. Results were assessed by the reduction in worm counts at post-mortem examination 8 weeks after treatment. Diamphenethide at a dosage rate of 100 mg/kg body weight was found 99.4 per cent effective. Rafoxanide at a dosage rate of 10 mg/kg body weight showed 98.78 per cent efficacy. Six weeks following treatment, infected animals treated with either drug exhibited significantly greater weight gain than the non-treated infected animals.
