ABSTRACT
Yadegari M, Ghahri H, Daneshyar
M., Effects of Satureja khuzestanica
oil on performancemarkers in heat stressed Ross broilers. Onl
J Vet Res., 21(7):351-357,
2017. Groups of twenty, 21-42
day-old Ross 308 broilers each, were given drinking
water with or without 0.4ml Satureja khuzestanica oil, and exposed or not
to 34 ± 2˚C, 8h daily for 42 days. Controls were not exposed to heat or
given extract. The light program was 23h light/1h dark. Weight gain (WG), feed intake (FI) and feed conversion ratio (FCR) were
calculated
on hen day for each period. Satureja khuzestanica extract did not
affect FCR, or organ weight. Findings suggest that Satureja khuzestanica
oil in
drinking water may
affect performance values in heat stressed Ross broilers.
Key
words: Satureja khuzestanica oil, heat stress, Ross broilers, performance.
