Research Reports
Corn germ is a co-product of the wet milling industry that is available for use in swine diets to partially replace the more expensive corn grain. Results of a recent experiment indicated that including 15% corn germ in diets containing 30% DDGS had no negative effects on pig growth performance, carcass composition, or pork fat quality. However, it is not known if greater quantities of corn germ may be included in diets fed to growing-finishing pigs. Therefore, we conducted an experiment to determine if greater levels of corn germ may be included in diets fed to growing-finishing pigs without negatively affecting growth performance, carcass characteristics, muscle and fat quality, or belly quality. The experiment also determined if the presence of DDGS in the diets influences the responses to the inclusion of corn germ.
Amino acid digestibility in Lemna Protein Concentrate fed to weanling pigs
Lemna Protein Concentrate is derived from the leaves of duckweed, one of several rapidly-growing aquatic plants of the genus Lemna. Duckweed has a number of advantages as a protein source. It is relatively inexpensive to produce and requires less growing area and fewer inputs than other plant protein sources such as soybean products. It also contains relatively little fiber, making it a highly digestible feed ingredient.
Podcasts
December 12: 30% corn germ may be included in diets fed to growing-finishing pigs
Jung Wook Lee, master's student in the Stein Monogastric Nutrition Lab, presents the results of an experiment to determine the optimal inclusion rate of corn germ in growing to finishing pig diets containing 0 or 30% DDGS.
