説明

Three heifers of Japanese Black were used for collection of fluid from the oviduct. A silastic cannula was inserted into the ovarian end of the oviduct and tied around the fimbrial end. The uterotubal junction was remained intact.<BR>Oviduct fluids were successively collected by cannulation for 11 to 41 days from three heifers. Secretion rates were from 0 to 0.9 ml/day and maximum secretion occured from the 1st to 3rd day of estrus. General means of the secretion rates, pH and total protein were 0.83 ml/day, 7.42 and 0.73 g/dl respectively. These items differed significantly between the heifers but did not differ signi-ficantly between the periods of the collection during the estrus cycle.<BR>Concentrations of sodium and potassium were 292.3 and 22.3 mg/dl of oviduct fluid respectively and not differed from these of the blood serum.
