Effet du stress thermique sur certain paramètres sanguins chez les poules locales (Gallus gallus domesticus)

Abstract

The two-factor ANOVA revealed a very highly significant influence (P <0.001) of thermal stress on rectal temperature to affect the hematocrit, blood cell count and leucocyte formula. Regardless of sex, the hematocrit was decreased (P <0.001) at 40 ° C. The blood count was increased to 35 ° C and then dropped to 40 ° C. With the exception of Eosinophilia, which was weakly influenced by heat stress, the other leukocyte types were strongly influenced by acute heat stress, with only monocytes and Basophils Affect by chronic stress.
