[Changes in the biochemical and hematological indices of chickens raised under high temperature and humidity]. / Vurkhu promenite v niakoi biokhimichni i khematologichni pokazateli pri pileta, otglezhdani pri visoka temperatura i vlazhnost.

Biochemical and hematological investigations were carried out with broilers raised at extreme temperature and humidity regimes-high temperature in combination with high relative humidity. Under the effect of high temperature (30-35 degrees C) and high relative humidity of the air (85-95 per cent) there was noted a rise of the lymphocytes and monocytes and a drop of the basophile, eosinophile, and pseudoeosinophile leukocytes in the white blood picture. After vaccination of the birds of the test groups with the vaccinal La Sota strain the blood serum showed negative titers. It was found that the Ca and P content in the blood serum of such broilers was higher as compared with that of the control group.
