Replacing expensive lactose in piglet feeds

Lactose is required in all piglet feeds, but its high cost often limits its use to the detriment of animal growth and health. Fortunately, other sugars can replace lactose without losing performance. “Lactose equivalent” ingredients reflect the fact that lactose and other sugars can be used interchangeably. This article examines these sugars and their unique characteristics.

Using vegetable proteins in pig and poultry feed

As animal proteins are increasingly being removed from animal feeds, vegetable-based feeds are becoming more popular.
