Changes in basal luteinising hormone (LH) concentrations and the LH response to gonadotrophin releasing hormone (BnRH) were examined in two groups of ovarietomised Bos indicus cross cows fed experimental periods each of three weeks. Ovariectomy significantly increasaed mean (+ -SE) plasma LH concentrations from 4.89 +- 0.15 ng/ml prior to surgery to 7.32 +- 0.22 ng/ml during a 10 week pre-experimental period post-ovariectomy. Individual animal variations and animal x ovariectomy interactions significantly affect post-ovariectomy LH concentrations. During nutritional treatmente periods one and two when group I cows were on the H treatment and group II cows on the L followed by the H treatment, mean basal plasma LH concentrations (ng/ml) were 10.18 +-0,74 and 10,58 +-1.07 for group I cows I cows and 7.51 +- 0.88 and 8.83 +- 0,65 for group II cows. In periods three and four when group I cows were on the L followed by the H treatment and group II cows on the H treatment in both periods, mean basal plasma Lh concentrations (ng/ml) were 4.55 +- 0,59 and 4.31 +- 0.49 for group I cows and 3.90 +- 0.61 and 4.44 +- 0.83 for group II cows. Plane of nutrition had no significant effect on basal plasma LH concentrations, but there were significant differences between periods in mean basal plasma LH concentrations. Following ... |
