Abstract
The objective of this work was to demonstrate whether pet food by-product (PFB) can be incorporated into nursery pig diets, as a replacement for more expensive animal-origin protein and energy sources. Two studies on early-weaned pigs were performed to evaluate growth performance as well as digestibility of diets containing various levels of PFB. Results indicate that PFB can serve not only as an effective replacement in nursery diets, but may also confer other long-term benefits.
