Abstract: To make the performance of some haematological indices of nonspecific resistance in sheep from two types of Karnobat local breed after a standardized load of the organism in the herd of the Institute of Agriculture - Karnobat a study with 12 sheep. For experienced material served of 6 sheep with clozed fleece and 6 with open fleece of 2.5 years. Testing animals had an average live weight, eat a similar regime under generally accepted norms and were kept under conventional conditions. It traces the main hematologic indicators of the blood. Studied the number of eosinophils, leukocytes, erythrocytes. Studied were: total protein, albumin, globulin and alkaline reserves. It was found that after a single standardized load in the blood of sheep of changes that would amount to reducing the number of eosinophils and increase the values of the parameters determining the adaptive capacity and metabolic processes - number of leukocytes and the content of total protein and globulin.
Almost all investigated indicators / with minor deviations/ or are higher in animals with open fleece, which they characterized as a adaptabilni and better metabolic processes. Based on the study of physiological indicators having the opinion that Karnobat local breed can be successfully incorporated into the organic farming system by selecting a preponderance of sheep with open fleece.
