Cloacal temperature responses of broiler chickens administered with fisetin and probiotic (<i>Saccharomyces cerevisiae</i>) and exposed to heat stress

Abstract There is dearth information on the role of fisetin as an antistress agent in ameliorating heat stress broiler chickens. Here, we experimentally compared probiotic, antioxidant and agent, with fisetin, little or no report its effect. Sixty-day-old chickens (Arbo Acre breed) were allotted into 4 groups 15 birds each follows; control, + probiotic groups, respectively. All administrations performed orally through gavage for treatment groups. The environmental cloacal temperature (CT) parameters measured bi-hourly at Days 21, 28, 35 from 7:00 to hr, during period study. exceeded thermoneutral zone probiotic-supplemented group had least overall mean CT values all experimental period. Based our findings, was not a potent mitigating birds.
