LUCERNE LEAF MEAL FOR PRE-WEANED DAIRY CALVES

Discipline: calf raising; 

The cost of supplementation is always a factor to be considered in calf starter diets. A nutritious and less expensive substitute in a supplement of a commercial pelleted concentrate is a possibility and lucerne leaf-meal was consequently considered by the authors referenced below.
