The economic impact of liver fluke can be very substantial. Liver fluke infection causes a reduction in growth rates (ADG), reduced milk production, reduced fertility, liver condemnation at the abattoir, mortalities (deaths) and secondary infections.
In high risk fluke areas liver fluke is a significant threat to optimal milk production. The effect of liver fluke on milk is well documented².
Liver fluke can affect weight gains (ADG) in all cattle, but especially in young and growing cattle. A heavy infestation of 200 fluke per calf, can cost up to 28,5% in reduced weight gain 4,5 The graph below shows the reduction in body weight expressed as weight loss on calves - depending on the severity of liver fluke infestation².
A reduced growth rate could affect the general development of the calf and can lead to reduced weaning weights or a delay reaching puberty (breeding age). Both these conditions have a major economic impact. With the current weaner price of >R25/kg, a small reduction in weaning weight will mean a big loss in income.
The loss of income due to liver condemnations caused by liver fluke infestation, can exceed R100 per animal slaughtered!
