Ninety-six commercial chicks were randomly divided into 4 groups and fed diets with 0.11, 0.2, 0.4, and 0.6% available P, respectively, for 30 days. Daily gains in groups 2 and 3 were significantly higher than groups 1 and 4, and so was feed consumption. The low P diets of 0.11% available P caused P deficiency and higher mortality of chicks. Growth retardation and sternum bending were the earliest symptoms of P deficiency.
