The effect of dietary protein on reproduction in the mare. VII. Embryonic development, early embryonic death, foetal losses and their relationship with serum progestagen.
Sixty-four Thoroughbred and Anglo-Arab mares aged 6-12 years were randomly allocated to 4 dietary groups and fed diets that differed in the total protein content and quality (essential amino-acids). Forty mares were non-lactating and 24 lactating. Eight mares were withdrawn from the investigation owing to injuries or gynaecological pathology. An overall conception rate of 94.6% and a foaling ra...

متن کاملThe Early Diagnosis of Foetal Distress.
THE problem of reducing perinatal mortality is closely related to the early and accurate recognition of foetal distress. Although the estimation of urinary oestrogen and/or pregnanediol before labour, and the continuous recording of the foetal heart rate during labour are of some value, the problem is far from solved. In this paper we present the results obtained with two less-known methods for...
