Title: Winter survival of trichostrongyle larvae: a study using tracer lambs. Author: Kerboeuf D. Journal: Res Vet Sci; 1985 May; 38(3):364-7. PubMed ID: 4012039. Abstract: Six groups of tracer lambs grazed from April to August on a pasture ungrazed since the previous November. A gradual decrease was observed in the worm burdens until July when a marked increase both in the number of worms and in egg counts was recorded. Haemonchus species were solely responsible for this sudden increase and it seems most likely that infection originated from larvae of the previous year rather than from overwintering eggs. Survival of Haemonchus species larvae in soil is suggested.[Abstract] [Full Text] [Related] [New Search]
