Canadian Research: Include More Ethanol Co-Products

Growing-finishing pig diets in Canada will likely include more ethanol products because of research being done at the University of Alberta, according to an article by Feed Navigator (http://bit.ly/…).

Dr. Ruuard Zijlastra is examining co-products from the food and biofuel industries to reduce the feed cost per pound of gain.

Co-products have been increasingly appealing in swine diets to reduce feed costs; however high inclusion rates can sometimes reduce feed efficiency, growth performance and pork quality.

Zijlastra wished to evaluate energy, amino acid and phosphorus content of newer co-products that are becoming available. He combined digestibility and bioavailability trials in order to formulate available nutrient content for various feed stuffs based on co-products.

Zijlastra said he was amazed to find the wide array of feedstuffs pigs could use in their diets at higher inclusions levels than would be considered previously, as long as the ingredients were correctly formulated based on a net energy system.

The co-products Zijlastra has worked to characterize include distillers grains and glycerol from ethanol products; he also looked at wheat bran, wheat millrun and wheat middling from flour milling.

The research will give producers the opportunity to use such feedstuffs and lower the cost per pound of body weight gain.
