To obtain information on basic haematological parameters associated with non-specific resistance of lambs from Karnobat local breed, depending on the type of protein in the ration obtained by inclusion in blends of grains of barley and wheat produced by organic and conventional technology in moderate herd of the Institute of Agriculture - Karnobat study was 20 lambs. For the purpose of weaned at 2 months of age lambs were formed two groups each of 10 animals - 5 with clozed fleece and 5 with open fleece square date of birth, live weight loners, male. The duration of the trial was 60 days. Feed being shot twic in both groups - controller - I group and experimentally II group. Group I lambs adopt concentrated feed composed of 50% concentrated mixture high protein 25% barley and 25% wheat high protein and group II - concentrated feed than 50% of that concentrated mixture low protein 25% barley and 25% wheat low protein. It traces the main haematological parameters of blood in the beginning and end of the experimenced period. Studied the number of eosinophiles, leukocytes, erythrocytes. Studied were: total protein, albumin, globulin, urea level, blood glucose and alkaline reserves. It was found that long needed a thorough research on morfological and fiziological researches and nonspecific resistance of Karnobat local breed in relation to the ability of this breed to be optimally used in animal production. Based on the study of physiological characteristics - the number of leukocytes, eosinophils, erythrocytes, it can be assumed that the adjustment is with open fleece type animals. With regard to levels of total protein, albumin, globulin, urea, alkali reserves, blood glucose, Karnobat local breed of sheep can be successfully incorporated into the system for organic farming, even in a lower level of protein.
