[Effect of a thermal factor on various biochemical indicators in the plasma of chickens].
The studies were carried out in 542 chickens of greenleg x polbar crossing. For detailed biochemical studies 443 birds were used. In a series of experiments the author studied the influence of temperature in three ranges: T1 = 12-14 degrees C, T2 = 18-20 degrees C, T3 = 24-26 degrees C on body weight, cholesterol level, basic phosphatase activity AP (E. C. 3.1.3.1), aspartic transaminase activity AspAT (E. C. 2.6.1.1), alanine transaminase activity AlAT (E. C. 2.6.1.2), the value of de Ritisa (WdR) coefficient, the level of total plasma protein including albumin, globulin alpha 1 alpha 2, beta, gamma, and the relation of albumin to globulin. The effect of the thermal factor was studied in the 5th and 8th week of life with regard to bird sex. The content of cholesterol in blood serum increased with the chicken age, in the 5th week--78,36 mg%, in the 8th week--96,9 mg%; the difference was statistically significant. AP and AspAT activity, however, decreased with the age, respectively, in the 5th week--91,46 K-A and 344,7 K units, and in the 8th week--73.61 K-A and 284.9 K units. The effect of the thermal factor caused in blood plasma highly significant differences in the mean AspAT and AlAt activity, in the mean level of WdR, albumin, globulin beta, whereas significant differences in the mean AP activity and mean level of gamma globulins. The highest mean activity of transaminases was obtained at the highest temperatures: AspAT 366.8 K units and AlAT 60,1 K units, whereas AP 95.1 K-A units at optimal temperature. The lowest mean albumin levels were found at T1 = 49.29%, and the highest at T3 = 51.29%.
