RESUMO
Fifty heifers were twice injected with I.C.I. 80, 996 and inseminated 72 h and 96 h after the second administration. Twenty eight of them (56%) became pregnant. Changes in plasma oestradiol-17 beta, progesterone and LH concentrations around the oestrus following the second injection were similar to those occurring in spontaneous oestrus. The pattern of testosterone secretion resembled that of oestradiol;-17 beta. The highest testosterone concentration (135 +/- 24 pg/ml) was measured on the third day after treatment with I.C.I. 80, 996.
