Abstract
The study was conducted to determine the baseline serum concentration of gonadotrophin hormones in Jennies. Nine mature Jennies aged between 3 and 5 years and weighing 150-180 kg were used in this study. Blood samples were collected weekly from all Jennies, starting at the first week of November till the last week of January. The serum concentration of FSH and LH were determined by ELISA methods using FSH and LH kits. The results showed that the mean of baseline serum concentration of FSH and LH are 2.90 ± 0.23 and 2.08 ± 0.25 ng/ml, respectively. The higher concentration of FSH was 3.36 ± 0.27 ng/ml which observed at the third week of January and the lower concentration was 2.54 ± 0.24 ng/ml that recorded at the third week of November. While the higher concentration of LH was 2.39 ± 0.48 ng/ml which observed at the third week of December and the lower concentration was 1.56 ± 0.46 ng/ml that recorded at the second week of January. There were no significance differences in serum concentrations of FSH and LH between the weeks, also there was no correlation between the concentrations of both hormones at the duration of the study. Further studies are required to determine the level of FSH and LH at different phases of Jennie’s estrus cycle.
