, : Ovum transfer in cattle. Vestnik Sel' skokhozyaistvennoi Nauki, Moscow, USSR (6): 85-95

55 Kholmogor cows and Russian Brown heifers were given 3000, 4500, 6000 or 9000 IU PMSG on the 15th or 16th days of the cycle, plus 2000 IU HCG on detection of oestrus. All females were inseminated 12 h after the administration of HCG, and laparotomised 5-8 days later. For the 4 treatment groups resp., the percentage of superovulated females was 20, 62.5, 83.3 and 100, and the number of corpora lutea averaged 1.8 (0-6), 4.5 (1-12), 8.0 (1-17) and 16.3 (2-34).
