Abstract
The study conducted at Bakrjo animal farm (Faculty of Agriculture, University of Sulaymaniyaha) from Sep. 15, 2004 to July 15, 2005 on 50 mountain black goat aged 2.5 to 3 years with average weight of 32 ± 1.2 kg. Goats divided randomly into two groups: 1st group with 10 (non-pregnant) goats as a control and 2nd group (40 goats) joined with 6 fertile male. Blood samples of 12 مل were taken from jugular vein on the 1st, 3rd and 5th days after birth and biweekly on lactation period for three months. The samples were divided into two parts, 1st part (whole blood) used to measure the followings: red blood cell count, haemoglobin conc., packed cells volume, white blood cell count, while the 2nd part (prepared as blood serum) used in measuring the conc. of blood Glucose, total cholesterol, total protein, the activity of Transaminase enzymes (AST and ALT) and alkaline phosphates enzyme. Milk yield were recorded weekly by hand milking once a week after isolating the lambs for 12 hours from. Haemoglobin conc. and packed cell volume highly significantly (P<0.01) decreased with advanced milking months in comparison to control group. Blood glucose conc. decreased significantly (P<0.05) on the 5th day after birth as compared with the control, while total cholesterol conc. decreased significantly (P<0.05) in the 1st and 5th day after birth and continued to decline during the months of milk production. Total protein conc. was significantly lower (P <0.05) in the 1st and 5th days after birth. AST activity increased significantly (P 0.05) in the 2nd month of milk production, while ALT activity increased significantly (P <0.05) in 1st, 3rd and 5th days after birth and the first two of milking months. Alkaline phosphates activity showed an increased significant (P<0.05) pattern in the 1st and 3rd days after birth and during the 1st and 3rd months of milking period. All simple correlation values lacked significance except for that between total cholesterol and milk production in the 3rd month (r = 0.44).
