Effect of lactose on the utilization of phosphorus from colloidal phosphate by chicks.

Abstract

SummaryThe effect of lactose, at levels of 5, 10 and 15% of purified and practical diets, on utilization by chicks of phosphorus from colloidal phosphate was studied. Data presented here demonstrated that utilization of colloidal phosphate by chicks was improved when diets were supplemented with lactose at levels to 10%. The pH of intestinal tract was lowered by lactose supplementation, although this effect was not uniform as lactose level increased.
