Abstract:

The effect of high aluminum concentration on phosphorus utilization was established with diets containing three different sewage-grown Micractinium algae which had been harvested by alum flocculation.

Inclusion of 25% algae meal in chick diets reduced the plasma inorganic phosphorus as compared with the control diet by 59% or 75% in an apparent proportion to the aluminum concentration in the algae – 3.9% and 5.3% alum, respectively.

The metabolizable energy concentration of the various samples ranged from 1864 to 2880 kcal/kg and the nitrogen absorption from 53.8 to 68.2%.

The nutritional value of one of the algae samples was assessed in a broiler and a layer trial. Diets formulated by computer in a linear-programming system contained 3, 6, and 9% in the broiler trial and in the layer trial 5, 10, and 15% of dried algae meal.

Inclusion of up to 6% algae meal in well-balanced broiler diets from 1 to 7 weeks of age had no adverse effect either on growth or on feed/gain ratio. A reduced feed intake in the young chicks due to 9% algae resulted in a graded decrease in weight gain, while in the finisher period the decrease of feed intake caused a reduction in the accumulation of abdominal fat.

In laying hens the significantly inhibited feed intake resulted in a corresponding decrease in layer performance.

The role of dicalcium phosphate addition to neutralize the deleterious effect of high dietary aluminum level is discussed.
