The study investigated the effect of work on the postpartum estrous cycle length and ovarian activity of crossbred dairy cows used for draught. Sixteen dairy cows were assigned to two dietary feeding regimes (i.e. diet 1=9 MJ ME/kg DM; diet 2=10 MJ/kg DM). The cows in both diets started to work a...

The luteolytic effect of prostaglandin F2á (PGF2á) during the confirmed luteal phase of the oestrous cycle was evaluated in ten Boran and ten Boran x Friesian cross-bred heifers. Following injection with 25mg Lutalyse, animals were bled every 6 h for 96 h and plasma progesterone (P4) determined ...
