Fluke animal report - - Council of Anglican Provinces of Africa
With reports of an increase in cases of liver fluke, farmers are advised to be aware of the problem, even if their herds have not previously been affected and they should take a strategic management approach to preventing and treating cases. Liver flukes have two suckers, both in the ventral side. The body surface is covered with numerous spines. Liver flukes have no external signs of segmentation. The mouth ends in the pharynx, a muscular tube that allows sucking. Condemnation of livers Reduced liveweight gains through reduced feed conversion efficiency. Reduced milk yields Reduced fertility Anaemia Diarrhoea. In severe (but few) cases - death Youngstock tend to be more susceptible to fluke, however adult cattle do still suffer from the disease. Where the cattle are out-wintered, for example suckler cows, they should be treated twice. Once during the October/December period to remove the infection that has built up over the summer months and a second time in April or May to remove any fluke.
What causes it? Liver fluke is caused by a parasite. Fasciloa hepatica. Fluke eggs, which are passed in the faeces of a mammalian host, develop and hatch into motile ciliated miracidia - a process which takes nine days at the optimal temperature of.
Fluke animal report
Left untreated liver flukes can live up to 20 years on sheep, usually not more than one year in cattle. Livestock grazing in regions with a high water table or frequently flooded are at high risk of becoming infected with liver fluke.
