Abstract: 

A number of 16 lactating ewes nursing lamb from Makuie and Ghezel breeds, aged between 3 to 5 years old was selected to determine 1) the concentrations of blood glucose (BG) and urea (BU), milk lactose (ML) and urea (MU) and their relationships to energy (ED) and protein diet (PO) in lactating ewes; 2) the blood and milk parameter changes during the lactation period; 3) estimation of the regression equations of energy and protein diet by using blood and milk parameters. A 5 ml Jugular blood vein, 50 ml milk and 200 grams of mixed food were prepared 15 days in interval up to 135 days (9 samples). The mean for energy and protein diet was 2.39 MCal/Kg/DM and 14.1%, respectively. The mean for BG, BU and MU were 48.5, 46.5 and 36.7 mg/dl and ML was 4.8%. The mean difference was significant (P<0.01). Blood and milk urea increased while blood glucose and milk lactose decreased. There were significant correlations (P<0.05) between BU&MU (r=0.45), BU&PO (r=0.83), MU&EO (r=0.75), MU&PD (r=0.79), MU& BG (r=0.75) and MU& ML (r=0.24). Regression equations for the prediction of dietary protein (R2=0.72) and dietary energy (R2=0.42) were also demonstrated. It is concluded that the mean parameters under study were at the range recommended by references. The differences among parameters indicate the variations in metabolism, digestion, absorption and composition of the food. Significant correlations among parameters and regression equations for the estimation of protein and energy diet in milking ewes indicate the reliability and importance of blood urea and glucose, milk lactose and urea as appropriate variables in the prediction of protein and energy diet in ewes.
