The aim of this study was to assess the effect of low environmental temperature on growth, feed conversion efficiency, carcass composition and some biochemical and haematological indicators in broiler chickens. The decrease in air temperature since the 22nd day of growth significantly influenced the level of total proteins, uric acid, phosphorus (in females), glucose (in males), haemoglobin (in females) and liver weight (in males). The temperature significantly influenced the level of triiodothyronine, haemoglobin (in males), haematocrit, abdominal fat content (in males) and heart weight. The decrease in environmental temperature (cold stress) during the growth of broiler chickens had a negative effect on the performance and blood system of the animals.
