Experiments were carried out with 72 cows of the Bulgarian Brown breed kept and fed under equal conditions, giving annually from 2600 to 2800 1 of milk. Groups were formed of animals, showing a normal and a pathologic puerperal period. Blood was sampled at one and the same hour, 7 to 10 days following calving. The levels were studied of vitamins (A, E, and C), total protein, protein fractions, blood sugar, and the bactericidal titer of the blood. It was found that except for vitamin A, which dependably dropped by 20.72% all other factors investigated showed unreliable deviations in cows with acute endometritis as against cows having a normal puerperium. Dependable was also the drop (by 13.93%) of the albumin fraction of the blood in cows with acute endometritis.
