Comparative survival of first-stage larvae of small lungworms Muellerius capillaris and Neostrongylus linearis of goats in alfalfa and ryegrass plots.
Faeces from a goat infected with M capillaris and from another infected with N linearis were used to assess survival of first-stage larvae under natural conditions in northwest France in mid-autumn, at the high-risk period. The faeces were deposited on 3 plots covered respectively with ryegrass, short cut alfalfa and high alfalfa. The desiccation of faeces and survival of larvae were tested at 1, 7, 14 and 21-d intervals. Survival of M capillaris was much higher than that of N linearis in all plots. The lower desiccations were observed in the high alfalfa plot whereas the best survivals were found in the 2 other plots. Vegetation where faeces are deposited may thus play a part in the accumulation of parasitic risk on a pasture.
