| Abstract |
Total number of 480 one-day old Arbor Acres broiler chicks were assigned to five treatments in two experiments. Diets were formulated to be isonitrogenous ( 23% CP , at starter-grower period and 20% CP at finisher period) and isocaloric ( 3100 kcal ME/kg diet at starter-grower period and 3200 kcal ME/kg diet at finisher period) to study the effect if adding some electrolytes ( 1% NaHCO3+ 1% KCl, 1% NaHCO3+ 1% NH4Cl and 1% kcl + 1% NH4Cl) or commercial electrolytes ( pharday and biophous) to broiler diets or drinking water, as well as iced water on growth performance, carcass characteristics, blood pH and rectal temperature. Results showed significant improvement in the performance of chicks fed mixture of 1% NH4Cl + 1%NaHCO3 compared with those fed on the other treatments. The heaviest bodyweight ( BW) and feed conversion ( FC) were recorded with chicks fed diets supplemented with mixture of 1% KCl and 1% NH4Cl. However, chicks feed electrolytes diets exhibited inferior results of body weight (BW) and feed conversion (FC) compared with other treatments. There was a slight decrease in PH value of blood when the tested electrolytes were added. Result showed significant improvement in percentages of dressing and total edible parts with adding dietary electrolytes. Economically, using ( 1%% kcl + 1% NH4Cl) recorded higher relative economic efficiency (EEF) values while the control was inferior to other treatments. The results showed that adding commercial electrolytes or ice water to broiler water had no significant effect on growth performance at 4 weeks of age. However body weight (BW), weight gain (BWG) and feed conversion (FC) were significant (p< 0.05) effected by the addition of commercial electrolytes or ice water at 4 to 7 weeks and the overall showed significant increase in dressing and total edible parts percentage by adding electrolytes to broiler,s water. Economically electrolytes or ice to broiler water recorded higher relative economic efficiency (EEF) values compared to control.
