| Abstract: | Contents: Abbovestrol® (Progesterone Releasing Intravaginal Device PRID) was administered to 5 non-pregnant cows intravaginally for 12 days (group 1). 5 other cows were left untreated as control group (group 2). Four animals in group 1 exhibited behavioural oestrus; peripheral plasma concentration of progesterone was 0.5 ng/ml and the oestradiol 17β concentration was similar to that in the control group. It is concluded that the Abbovestrol® device can induce a fertile oestrus in Zebu cross bred cattle. |
