| Popis: | Extract A survey of 1000 dairy herds in England and Wales, by the U.K. Milk Marketing Board during 1955–7 showed that 1% of the cows were affected with clinical mastitis at any one sampling. In 1957–8 the Animal Health Division of the U.K. Ministry of Agriculture undertook a national survey of wastage and disease in dairy cows (Leech et al., 1960). Their estimate for a seasonal prevalence of 10% of cows affected with clinical mastitis was corroborated by a second national survey in 1964 (Leech et al., 1964). |
