Abstract

Effect of GLOBACID^® acidifier in different stocking densities on performance and blood metabolites was examined using 576 one-day broiler chickens Ross 308 in a completely randomized design with 6 treatments and four replications for each treatment through a (3 × 2) factorial arrangement with three levels of stocking densities (14, 16 and 18 chicks per square meter) and two levels of GLOBACID^® acidifier (zero and one kg per each ton of feed). The lowest feed intake was seen in 18 stoking density treatment which fed one kg of acidifier in the ration and this treatment was significantly different with other treatments (P<0.05). Feed intake was significantly lower in broilers which received acidifier compared with others that did not receive acidifier (P<0.05). Increasing the density from 14 to 18 birds per square meter increased feed conversion ratio (P<0.01). Birds that received acidifier had lower feed conversion ratio than others (P<0.05). Feeding diets containing acidifier lead to a reduction in glucose and antibody titers against SRBC and an increase in cholesterol and triglyceride in broilers blood plasma (P<0.05). The interaction between stocking densities and acidifier on body weight and blood metabolites was not significant. Therefore, using acidifiers in high stocking densities have some advantageous in broiler performance.
