Perinatal disease conditions of sheep in New Zealand

Abstract

Extract A previous paper ( Hartley and Boyes, 1964 Cunningham, I. J. 1946. N.Z. J. Sci. Tech., 27A: 381–381. [Google Scholar] ) reports investigations carried out in New Zealand to ascertain the incidence of the major causes of ovine perinatal mortality. The present paper describes the disease entities encountered in the several thousand lambs autopsied at Wallaceville in the period 1951–1962. Some of these conditions have been reported before and will be reviewed, others are recorded here for the first time.
