The effect of NaHC03, NH-tCI and KCI on the performance of broiler chickens under cyclic heat stress

The study was conducted with 224 Arian broiler chickens which were assigned in a 6-week age period (7-49 day) with 7 treatments and 4 replicates (8 chickens for each replicate) based on a completely randomized design. The treatments contained three chemical materials added to the basic diet at levels of O. J or 0.3 percent, and the control treatment. The results of this experiment showed that body weight was significantly increased by treatments, (p::S0.05) but the effect of treatment on feed consumption was not signi ficant. The treatments containing ammonium chloride (0.1% and 0.3%), potassium chloride (0.1 % and 0.3%), and sodium bicarbonate (0.1 %) had a significantly higher body weight and better feed conversion ratio (p::S0.05) relative to control group. The treatment with 0.3% ammonium chloride had the best performance, compared to the other groups. The difference between feed consumption was not significant. According to the results of this experiment, using ammonium chloride, potassium chloride up to 0.3% and sodium bicarbonate at 0.1% in heat stress condition is suggested.
