Observations on the genital tract of cull ewes.

Genital tracts were collected from non-pregnant cull ewes in early April and examined for macroscopic abnormalities. An assessment was made of the possible effect of any abnormality on the ability of the animal to become pregnant. It was found that 23.2 per cent of the tracts had abnormalities and it was considered that 16.8 per cent had abnormalities likely to interfere with the establishment of pregnancy.
