Nutritional Improvement of Corn Ethanol Co-products via Yeast Engineering

(2016)
University of Minnesota/Bo Hu

Co-products generated from corn ethanol biorefining, for instance, Distiller’s Dried Grains with Solubles (DDGS), are very attractive in animal feeds as partial replacement of some more expensive and traditional feeding materials for energy (corn), protein (soybean meal), and phosphorus (monoor di-calcium phosphate). However, variability in nutrient content and digestibility, especially the lower digestibility of most amino acids compared to corn and soybean meal, has been observed, and extra undigested nutrients are then excreted to the manure,

Whole Corn Grain Meal Inclusion in Commercial Shrimp Feeds

(2016)
RALCO Nutrition/Misael Rosales

The world farm production of shrimp in 2014 was 9.02 billion lbs. The estimated world consumption of feed consumed by shrimp farms was 16 – 20 billion lbs. in 2014. Wheat grain and/or by-products (e.g. wheat middlings) levels typically average around 30% of shrimp feeds. Thus, approximately 4.8 billion to 6 billion lbs. of wheat grain and/or by-products were consumed by commercial shrimp feeds in 2014. The world’s shrimp farm production is increasing by over 7%/year with the prediction to reach the size of chicken production in the future.
