Leading Research: tagged calcium
This series of studies investigated the presence and extent of an ‘appetite’ for an extra-dietary source of Ca in laying hens and established the optimum Ca and P concentrations and ratios of dietary Ca for optimum egg production and nutrient digestibility.
Two experiments were conducted to determine the available phosphorus (AP) requirement of laying hens and to examine the effect of different dietary AP and calcium (Ca) concentrations on egg production and egg shell quality from the start of lay to 80 weeks of age.
The Relationship Between Calcium Nutrition, Appetite, Growth, Production and Skeletal Development in Early Egg
This research report examines the relationship between body weight, feed intake, calcium nutrition, egg production and skeletal calcium content in three experiments using imported brown egg layers.
This study shows that the low calcium supplementation produces sustained improvements in post-moult performance. .
