- •
Twin pregnancies could be identified as early as day 28 post AI analysing plasma PAG I and II.
- •
Plasma PAG-I, PAG-II and P4 concentrations were significantly higher for twin than for single pregnancies.
- •
Cows with single pregnancies did not show higher plasma progesterone concentrations if they had an additional corpus luteum.
