The effects of citric acid on phytate-phosphorus utilization in young chicks and pigs.
Several bioassays were conducted with young chicks and pigs fed phosphorus (P)-deficient corn-soybean meal diets. With diets for chicks containing .62% Ca and .42% P (.10% available P), graded doses of a citric acid + sodium citrate (1:1, wt:wt) mixture (0, 1, 2, 4, or 6% of diet) resulted in linear (P < .01) increases in both weight gain and tibia ash. Relative to chicks fed no citric acid, ti...

متن کاملEffects of low phytic acid corn on phosphorus utilization, performance, and bone mineralization in broiler chicks.
In vivo and in vitro experiments were conducted to determine whether P in a low-phytate corn (LPC) containing the lpa 1-1 allele is more available than P in a near-isogenic wild-type corn hybrid (NC). The LPC was analyzed to contain 0.18% nonphytate P and 0.26% total P (TP), whereas NC contained 0.05% nonphytate P and 0.25% TP. For these studies, nonphytate P was considered to be available P (A...
متن کاملEffect of sources of maize and maize particle sizes on the utilization of phytate phosphorus in broiler chicks
Two experiments were conducted to test the effects of sources of maize and maize particle sizes on the utilization of phytate P in broiler chicks fed on maize±soyabean meal diets de®cient in P. In Experiment 1, maize from four consignments was ground separately using the same milling facility. Four maize±soyabean diets representing each maize source, and two control diets made of maizestarch±so...
متن کاملPhosphorus characterization in feces from broiler chicks fed low-phytate barley diets
The inclusion of low phytate grains in poultry diets can reduce the phosphorus (P) content of poultry feces, but their influence on fecal P composition is not well established. To assess this, 100 male broiler chicks (21 days old) were fed dietary treatments based on either a wild-type barley or one of three low phytate mutant barleys with 59, 62 and 99% reductions in phytate P, compared with t...
