الفحص الإيضي الجانبي لأبقار الحليب في محطة الاسحاقي

الملخص EN

Metabolic profile test was done on Friesian cows of Al-Ishaqi plan.

Blood samples were collected from 21 cows in the second lactation stage, 7cows with high Milk yield, 7cows with moderate milk yield& 7cows with low milk yield.

Estimation of the following were done; hemoglobin, packed cell volume blood urea nitrogen glucose total protein albumin& globulin, in three periods (1month after calving, 4month after calving, 7month after calving).

The results revealed that Hb, total protein & globulin ratios were increased, while the albumin ratio was decreased in the first period, PCV increased in the third period, albumin ratios showed higher levels in high milk yield cows, BUN show higher levels in the first period, increased levels of BUN in high milk yield cows, low levels of blood glucose in the second period.

Signification correlation coefficient between total protein ratios& Hb, globulin ratios& BUN were obtained, while significant negative correlation between total protein& albumin was existed.

Regression equations between total protein ratios& all blood traits were calculated.
