Extract

A Number of authors (Bonsma and Neser, 1951; Bisschop, 1954; Wiener and Donald, 1955) have recently provided experimental evidence on the age at which the eruption of permanent incisors occurs in cattle and, in view of the wide ranges generally encountered, criticised the practice of estimating age from dental development. Though factors such as individuality, breed, plane of nutrition and type of grazing are frequently quoted as being responsible for deviations from the ‘accepted’ means (Miller and Robertson, 1952; Zorn, 1953), apparently little support is to be found in the scientific literature on the subject.
