چکیده
citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broiler chicks in 48 pens received one of the eight experimental diets containing two levels of dietary rice bran (20% or 30%), citric acid (0% or 2%) and non-phytate phosphorus (0.25% or 0.35%) ad libitum from day 21 to 42. retention of nitrogen, phosphorus, mineral and dry matter was determined using a total collection trial. feed intake, weight gain, feed conversion ratio and weights of feather, liver, gizzard and pancreas were not significantly (p>0.05) affected by the levels of dietary rice bran, citric acid, or non-phytate phosphorus levels. retention of nitrogen, phosphorus or dry matter were not significantly affected (p>0.05) by the levels of dietary rice bran, citric acid, non-phytate phosphorus or their interactions. 2% citric acid improved the retention of mineral with 30% rice bran compared to diets with 20% of rice bran. there was no significant difference (p>0.05) in tibia ash when diet contained 20% or 30% rice bran. a significantly (p

Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...
