Abstract
The effect of dietary urease and urease injections on growth rate and feed efficiency was studied, using 622 broiler-strain chicks and 51 male weanling rats. Urease injections totaling from 20.0 to 61.5 Sumner units were given at various periods of chick and rat growth. Dietary urease was fed at levels from 44 to 132 Sumner units per 454 g of chick diet. In no instance did the imposed treatment cause statistically significant differences in the measured growth responses or in feed efficiency.Keywords
