Parasitological and biochemical studies for 82 heads (12.2%) showing sterility syndrom out of 672 heads of Korean native cattle were undertaken by analysis of blood values for their contents and examination of their vaginal swabs for Tritrichomonas foetus 1. Tritrichomonas infection of Korean cattle revealed 7 positive cases (8.54%) out of 82 infertile heads. 2. Contents of their serum protean, carotenoid, vitamin A and phosphorus were determined in summer and winter season and the following results were obtained. a) In summer season, average blood value of 30 cattle showing sterility syndrom were determined as protein 7.52g/100ml, carotenoid 165.1g/100ml, vitamin A 173.9 IU/100ml and phosphorus 7.48mg/100ml, respectively. b) In winter. season, average blood value of 52 cattle showing sterility syndrom were determined as protein 7.76g/100ml, carotenoid 413.3g/100ml, vitamin A 174,3 IU/100ml and phosphorus 7.54mg/100ml, respectively.
