Feeding By-Products High in Concentration of Fiber to Nonruminants

摘要

Fibrous feeds traditionally have not been used for nonruminants due to their documented depression of diet digestibility in pigs and poultry. However, some types of fiber and fiber sources do not exert such negative effects on nutrient digestibility in older growing pigs and sows. Dietary fiber can have positive effects on gut health, welfare, and reproductive performance of pigs. Hence, nutritionists are attempting to gain a more thorough understanding of dietary fiber in swine diets. In contrast, the potential for use of fibrous feedstuffs in poultry diets is more limited with two exceptions. First, high fiber diets have important value in welfare-friendly molting programs for laying hens. Secondly, the need for controlled growth of pullets and turkey breeder candidates makes fibrous feedstuffs useful in these phases of poultry production.
