The influence of iron deficiency state on metabolic processes and intensity of lipids peroxidation processes at dawn-calving cows was analysed in the conditions of the Republic of Belarus. In course of study there was determined the intensity of lipids peroxidation processes in blood plasm depending on the level of hemoglobin and red blood corpuscle quantity. It was studied that in animals with low hemoglobin the oxidizing stress proceeded more actively than in animals with the normal hemoglobin level. Data analysis of lipids peroxidation processes showed that pregnancy condition was accompanied by strengthening of mentioned above processes. That fact was proved by the indicators of lipids peroxide oxidations presented both in absolute and in relative units. The content of diene conjugates, containing in 1 mg of lipids, was in 1,3-1,8 times higher at pregnant cows in comparison with non-pregnant ones, trieneketones content - in 1,2-1,6 times. Similar differences were observed in the process of analysis of diene conjugates and trieneketones values rated per 1 ml of plasma. More considerable differences were stated for trieneketones; the analysed indicator was in 1,6-2,1 times higher at pregnant cows
