Abstract: (6324 Views)
This study was carried out to evaluate the impact of litter additives on growth performance, immune system response and the incidence of ascites syndrome in broiler chickens. This experiment was investigated in a completely randomized design with four treatments and four replications and 24 day-old chicks in each pen. Experimental treatments were addition of 1) aluminum sulfate + CaCO3, 2) natural zeolite + citric acid, 3) treatments 2 and 3 together, to litters and a group with no litter additive was considered as control. Litter additives were applied on surface of the litters by 1.115 kg/m2, at 24 h before arrival of the birds. Weight gain, feed consumption and feed conversion ratio were not affected by the treatments (P>0.05). On day 42 posthatch, mortality, the incidence of ascites, heart relative weight, right ventricular relative weight, heart ascites index (AHI) hematocrit and dermal and humoral antibody response to phytohemaglotinin and sheep red blood cells inoculation were not affected by the treatments (P>0.05). Birds reared on the litters treated with aluminum sulfate + CaCO3 and natural zeolite + citric acid showed significantly greater means for bursa and spleen relative weights respectively (P>0.05), while there was not significant difference among other treatments. The pH value and moisture percentage were significantly affected by treatments until 5wk (P>0.05). On day 42, pH value, moisture and nitrogen (%) in litter were not affected by treatments (P>0.05). It could be concluded that while litter additives enhanced some of litter characteristics, it did not have effect on broilers performances.
