Presence of parasite larvae in goat manure for use as fertiliser

Some livestock farmers utilise goat manure to fertilise grasses grown for animal feed, which
may lead to parasitic diseases caused by strongyle infection. Therefore, the presence of
strongyle larvae in manure needs to be determined. In this study, goat faeces containing
strongyle eggs were deposited into five replicates for daily sampling throughout 23 days and
subjected to faecal egg count, larvae identification and enumeration. Absence of eggs was
detected on Day 4 when the infective larvae of Haemonchus contortus, Trichostrongylus
sp. and Oesophagostomum sp. were found. Larvae counts reached a maximum of 164
larvae on Day 8 and were negligible by Day 14, by which time the manure can be used as
fertiliser to grow forage crops for animal feed.
