| Popis: | Diets with varying levels of Ca, inorganic phosphorus (P1), and vitamin D3 were fed to chicks from 1 day of age. Alkaline phosphatase of intestinal mucosa was twofold higher at 3 weeks in female chicks fed 0.16% of P1 than in chicks fed 0.48% of P1 when the diets contained 7500 I.C.U. of vitamin D3 per kilogram and 1% of Ca. The effect of low dietary P1 was less pronounced when the diets contained 450 I.C.U. of vitamin D3 per kilogram and 1% of Ca but no definite pattern in enzyme activities due to level of P1 was observed with 0.53% of Ca. In male chicks there was a small but consistent increase (35–45%) in the activity of intestinal phosphatase when the diets were low in Ca, P1, or both. The level of vitamin D3 had no effect on the intestinal enzyme in male birds. |
