Effect of dietary tomato powder on growth performance and blood characteristics of heat-stressed broiler chickens.

This study investigated the ameliorative effect of dietary tomato powder (TP) on performance and blood characteristics of broilers under heat stress condition. A total of 240 (21 days old), unsexed Marshall broiler chicks were allotted to four dietary treatments having 6 replicates of 10 birds each in a completely randomized design (CRD). The birds were exposed to ambient temperature of 33 °C between 8:00am and 5:00 pm and relative humidity of 81.
