OVARIAN BLOODFLOW IN SHEEP DURING THE OESTROUS CYCLE

It is uncertain whether ovarian bloodflow in ewes remains constant or varies with the stage of the oestrous cycle. In an experiment in which `minimal estimates' of the ovarian steroid secretion rates were obtained, Short, McDonald & Rowson (1963) cannulated the "major vein draining the corpus luteum or ripe Graafian follicle". The bloodflow rates obtained were lower in oestrous than in di-oestrous ewes. Moore, Brown & Smythe (1965) using a similar technique did not find that the rates varied cyclically.

In the present study, seventeen Merino and five Corriedale ewes were used. They were 5 to 7 years old and had regularly exhibited oestrus at intervals of 17 days. Anaesthesia was induced and maintained with sodium pentobarbitone except on nine occasions when anaesthesia was maintained with fluothane. The abdomen was opened by
