| Abstract | ||
| The study conducted in private sheep farm near Kirkuk city during the period from Nov 1st 2015 to Jan 30th 2016. The experiment included 50 Awassi ewes aged 2.5 - 6 years to investigate the relationship between some blood parameters and biochemical concentrations with milk yield and its composition during suckling period. Three blood samples were withdrawn (1st sample after birth by 15 days and the others after a month subsequently). Each blood sample divided in two parts, the 1st (whole blood) used to calculate some blood parameters (Packed cell volume PCV and Hemoglobin concentration Hb), the 2nd part is used to obtain a blood serum to determine some blood biochemical concentration (glucose, cholesterol, total protein and albumen) and some ion concentration (Potassium and Sodium). Daily milk yield (DMY) were calculated by ewes hand milking biweekly. The obtained results of this study could be summarized as follow: Milk fat percentage have significant positive correlation with blood potassium level in the 1stmonth and significant negative correlation with blood cholesterol concentration in the 2nd month of lactation period. There were also significantly positive correlation between milk protein percentage and blood cholesterol concentration in the 1st month and between milk protein percentage with blood albumin, sodium and potassium for the 3rd month. Solid not fats percentage showed significantly negative correlation with blood potassium, significantly positive correlation with blood cholesterol concentration in 1st month, while its correlation with PCV, Hb, blood cholesterol and sodium ions concentrations were significantly positive in 3rdmonth of milk production. | ||
