	abstract = {The prevalence of mastitis in New Zealand ewes has not been studied for over 40 years. Quinlivan (1968a,b) examined 19427 Romney ewes in the lower North Island and detected mastitis in 0.6-1.7\%. Clarke (1972) surveyed 118249 ewes in the lower South Island and found the incidence of mastitis was 0.6-0.7\%. Skyrme (1970) reported the occurrence of {\textquotedblleft}hard udders{\textquotedblright} and implicated them in lamb deaths. Perhaps because of such reports of low incidence, little research into sheep mastitis has been done in New Zealand...},

	abstract = {The effect of experimentally induced clinical mastitis in the early dry period (EDPCM) upon the milk production in the subsequent lactation was examined. Animals with low somatic cell counts at herd test (n=165) were experimentally exposed to Streptococcus uberis in their early dry period in an efficacy study of two external teat sealants. Animals that developed EDPCM after challenge (n=127) were treated with an antibiotic after observation of clinical mastitis. Total lactation yields of milk, fat, protein and milk solids were analysed with respect to treatment group (fixed effect) and the covariables: calving week (linear), parity (linear and quadratic) and proportion of Holstein-Friesian genes (linear). For animals that suffered EDPCM and those that did not, there was no difference in production (milk yield; 5126 vs. 5010 litres, fat yield; 267 vs. 264 kg, protein yield; 182 vs. 179 kg). It was concluded that promptly treated EDPCM due to S uberis, did not affect production in the subsequent lactation.},
