UTILIZATION OF CALCIUM IN CANOLA MEAL SUPPLEMENTED LAYING DIETS

JOHN D. SUMMERS, DIANE SPRATT, Steve Leeson

Abstract

White Leghorn pullets were offered a corn, soybean meal laying diet or similar diets containing 15% canola meal. These diets were fed with dietary calcium levels of 3 and 5% and two levels of supplemental phytic acid (0 and 0.2%). A significant decrease in feed intake was noted with the canola meal diets. Poorer shell quality was noted for the canola versus the soybean meal diets, the low vs. high calcium diets and the phytic acid supplemented vs. nonphytic acid supplemented diet. Key words: Canola meal, laying hens, phytic acid, calcium
