Context Breech strike is a serious disease for wool sheep. Skin wrinkle and dags are known predisposing factors for breech strike; however, a large part of the variation among sheep is unknown. Aims We studied the natural diversity and difference in

Context Production losses, due to worms and anthelmintic costs to control the infection, can affect the profitability of sheep production systems. Aims This study was carried out to quantify the production benefits of worm-resistant sheep. Methods Ge

Context Mulesing provides a high degree of protection against beech strike, but wool producers need to be able to predict the level of risk of flystrike if they cease mulesing. Aims To use data from trials of mulesed and unmulesed sheep to estimate t

Breech strike is caused by the infestation of maggots from Lucilia cuprina on the skin of susceptible sheep. Crutching and mulesing modify the potential expression of breech strike, because crutched and mulesed sheep have a lower risk of being struck

The present study reports on changes in faecal worm-egg counts (WEC), larval composition, and the number of worms at different developmental stages in young sheep sourced from a flock selected for reduced faecal worm-egg counts over 15 years. The she

Sheep that are highly resistant to parasitic nematodes can suffer bad diarrhoea due to the inflammation associated with rejection of ingested larvae from pasture. We hypothesised that challenging parasite-resistant sheep indoors with nematode larvae

The progeny groups of resistant and susceptible sires to breech strike were compared for phenotypic differences in conformation and visual score traits recorded from birth to 5 years of age. The incidences of breech strike in the two most resistant s

Factors responsible for an increase in breech strike were investigated in an unmulesed Merino flock in a Mediterranean environment that were not crutched in 4 years but were crutched in the subsequent 2 years. No chemical preventative treatments such

Pruritic behaviour and deranged fleece are often used as indicators of sheep louse infestation but the exact relationship between infestation and the observation of signs of pruritus was unclear. Two studies were conducted to examine this association

Fecal egg count (FEC) has been widely used as an indicator of host resistance to gastrointestinal parasites in sheep and has been shown to be a heritable trait. Two other possible indicators of parasites, dag score (DS; accumulated fecal material) an
