| This study was conducted at Animal Farm of Agriculture College, Basrah University from 1-12-2009 to 31-12-2010. Thirty Arabi female lambs were selected randomly and divided equally into three levels of nutrition (1,2,3 % barley of body weight) from weaning to first birth . The aim of the study was to investigate the effect of nutrition and lambs sex on levels of some sex hormones (Estrogen, Progesterone, Follicle-Stimulation Hormone and Luteizing Hormone) and some metabolic hormone ( Growth Hormone, Insulin-like Growth Factor-1 and Leptin) during pregnancy period. Results showed a significant (P<0.05) increase in steroid hormones , IGF-1 and leptin concentrations of the third group in comparison with first group during the whole pregnancy period. Significantly (P<0.05) difference in gonadotropin hormones presented between first and third groups at the first and last month of pregnancy. Estrogen, FSH , LH and leptin hormones recorded low concentrations during mid-pregnancy in comparison with first and last month of pregnancy. In contrast progesterone level was high. | ||
