I/m injection of 2.5 mg oestradiol benzoate produced biphasic changes in NEFA. After 2 hrs NEFA decreased, but thereafter an increase occurred and maximum levels were reached after 24 hrs. Blood glucose increased from 12 to 48 hrs after the injection. Serum cholesterol fell after 24 hrs., but thereafter the level increased and maximum values were obtained after 120 hrs. Progesterone at the same dose did not change any of the measured parameters. Simultaneous administration of oestradiol benzoate and progesterone gave responses similar to oestradiol benzoate alone. Blood glucose and NEFA were followed during heat in a lactating cow. Both parameters increased after ovulation.
