Effect of phytic acid dietary level on growth performance and serum components in broiler chickens

Abstract

This study was conducted to elucidate the effects of dietary phytic acid supplementation on organs and serum components in broiler chickens. A total of 30 1-day-old broiler chicks were divided into three treatment groups (n=10, each). The control group was fed normal diet and the other groups were fed diet supplemented with 0.06% and 0.12% phytic acid for 30 days. No differences in body and muscle weights and 21 serum biochemical parameters were detected between phytic acid treatments and the control. However, abdominal fat weight decreased significantly with 0.12% phytic acid treatment (P<0.05). Liver weight and certain serum lipid parameters changed slightly, although differences were not statistically significant. In addition, the correlation coefficient between abdominal fat and liver weights was 0.69 (P<0.05) in the control group, whereas no significant differences were observed in the phytic acid fed groups. It is possible that phytic acid may affect lipid metabolism in liver and/or abdominal adipose. © 2012, Japan Poultry Science Association.
