Abstract
This study was carried out to investigate the effects of dietary Saccharomyces cerevisiae (wild yeast mutant) and Saccharomyces cerevisiae hFeHLC (ferritin containing yeast) and chelated Fe on growth performance and body composition of broiler chicks. A total of 252 (1-day old) 'Ross' broiler chicks were allotted to seven dietary treatments: I) control without iron supplementation, 2) 0.1% wild yeast mutant (YM03), 3) 1.0% wild yeast mutant, 4) 0.1% ferritin containing yeast (YF04), 5) 1.0% ferritin containing yeast, 6) 0.01% chelated Fe and 7) 0.1% chelated Fe. The highest weight gain obtained from broilers fed 0.01% chelated Fe was 2,121g, the lowest weight gain obtained from broilers fed control diet was 2.087g. The growth performance results were not significantly different in weight gain, feed intake and feed conversion ratio of broilers diets containing wild yeast, ferritin containing yeast and chelated Fe supplementation and control diets (P>0.05). The lowest iron content in meat was for control 30.51 mg/dL and the highest Fe content was for 0.1% ferritin containing yeast 41.58 mg/dL, but these were not significantly different (P>0.05).
