The nutritional requirement of rabbits, as is the case in other mammals, varies according to age and productive performance. To obtain effective feeding efficiency, diets should be formulated to meet the needs of animals of a particular age or stage of production. Most rabbit farms are not large enough to justify the use of several different feeds, so it is a common practice to use just one diet for the entire herd. Since rabbit farming is becoming more intensive, it is suggested that rabbit producers should use at least two diets, a grower diet for fryers and a lactation diet for does.
