Abstract: The concentrations of LH and FSH in blood plasma were measured by radioimmunoassay during the annual cycle of two local goat breeds in Shandong with low (Yimeng Black goat) and high (Jining Gray goat) fecundity. The results showed that the secretion of the two hormones in each breed changed with season obviously which was highest in autumn, secondary in spring and lowest in summer. FSH and LH levels in plasma showed a wave pattern in each breed during twelve months. The mean concentration of FSH was higher in Jining Gray goat than that in Yimeng Black goat in different month or season, but it was not significant (P>0.05 ). The level of LH in plasma was similar in the two breeds.
