Research report: Effects of including conventional or high protein canola meals in diets for nursery pigs

Canola meal is a by-product of the canola oil industry. Conventional canola meal contains about 37% crude protein, and is a good protein source for swine diets. New varieties of canola with seeds that contain less fiber and more protein than conventional canola seeds have been hybridized. The meals produced from these new hybrids have a crude protein content similar to that of dehulled soybean meal. No data exist on how feeding these high protein canola meals to weanling pigs affects growth performance. Inclusion levels also have not been established for the use of these products in nursery diets.

An experiment was conducted to determine the effect on growth performance of including conventional or high protein canola meals at different levels in diets fed to weanling pigs.

Research report: Energy and phosphorus digestibility by weanling pigs of Lemna Protein Concentrate, fish meal, and soybean meal

Lemna Protein Concentrate (LPC) is derived from the leaves of duckweed, one of several rapidly-growing aquatic plants of the genus Lemna. LPC is produced by de-oiling and de-hydrating leaves and stems of the duckweed plant. 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. In addition, LPC has a favorable amino acid profile for use in swine diets. No published data exist on the nutritional value of LPC as fed to pigs. Therefore, two experiments were conducted to determine the concentration of digestible and metabolizable energy and the digestibility of phosphorus in Lemna Protein Concentrate.

Podcast: Retention and digestibility of Zn, Cu, Mn, and Fe in pigs fed diets containing inorganic or organic micro minerals

Dr. Yanhong Liu is a postdoctoral research fellow in the Stein Monogastric Nutrition Lab. In this podcast, she reports on research to determine the digestibility and retention of micro minerals in pigs fed either inorganic or organic sources of zinc, copper, manganese, and iron. Adapted from a presentation at the 2013 ASDA-ASAS Joint Annual Meeting, Indianapolis, IN, July 8-12.

Podcast: Amino acid digestibility in canola meal, 00-rapeseed meal, and 00-rapeseed expellers fed to growing pigs

Tanawong Maison, a Ph. D. student in the Stein Monogastric Nutrition Lab, discusses an experiment to determine concentrations and standardized ileal digestibility of crude protein and amino acids in canola and 00-rapeseed products fed to growing pigs. The experiment compared canola and 00-rapeseed meal produced from plants grown in different locations, as well as 00-rapeseed meal products resulting from different oil extraction techniques. Adapted from a presentation at the 2013 ASDA-ASAS Joint Annual Meeting, Indianapolis, IN, July 8-12.

Press release: Comparing amino acid digestibility in different blood products fed to pigs

URBANA, Ill. - Because weanling pigs don't tolerate great quantities of soybean meal in the diet, alternative sources of protein must be used. Blood products, such as blood meal and plasma protein, are common ingredients in weanling pig diets and are considered  high quality sources of amino acids. Researchers at the University of Illinois have determined the amino acid digestibility of five blood products produced in the United States to provide swine producers with guidance for the use of these products in formulating diets.
