Effects of heat heat stress of some blood parameters in broilers

Bu çalışmanın amacı etlik piliçlerde akut sıcak stresinin hemotokrit değerleri ve lökosit komponentlerinin oranları üzerine etkisini saptamaktır. Etlik piliçlerin 44 gün yaşında 2 saat süreyle 39±1 C° sıcak stresine maruz kalmaları rektal sıcaklık, heterofil ve bazofil oranlarında artışa neden olmuştur. Etlik piliçlerin akut sıcak stresine maruz kalmaları monosit ve lenfosit oranlarında azalmaya sebep olurken, eosinofil ve hemotokrit değerleri etkilenmemiştir. Etlik piliçlerde vücut sıcaklığının artmasına neden olacak kadar yüksek çevre sıcaklığının lokosit komponentlerini de değiştireceği sonucuna varılmıştır.

Etlik piliçlede sıcak stresinin bazı kan parametreleri üzerine etkileri

The purpose of the present study was to determine the effects of acute heat stress on the proportions of leucocyte components and hematocrit values in broiler chickens. Exposure of broiler chickens to 39±1 °C for 2 h at 44 d of age caused an increase in rectal temperatures, and in heterophil and basophil ratios. The H/L ratio also increased from 0.25 to 0.43. The exposure of the broilers to acute heat stress resulted in decreased monocyte and lymphocyte proportions whereas the proportion of eosinophil and the hematocrit values were not affected. It was concluded that a temperature high enough to cause increased body temperature also changes circulating leucocyte components in broilers.
