Lupin Bean Meal Toxicosis in Swine

Studies on the Glycosidases in Jack Bean Meal

The monosaccharide u&s most commonly found in glycoproteins are n-galactose, n-mannose, M-acetyl-u-glucosamine, sialic acid, and L-fucose. The hydrolysis of individual carbohydrate units by specific glycosidases is an excellent tool for studying the sequenbial arrangement and anomeric configuration of the carbohydrate units in the glycoproteins. In previous studies, cr-mannosidase (cr-u-mannosi...

Recent advances in canola meal utilization in swine nutrition.

Canola meal is derived from the crushing of canola seed for oil extraction. Although it has been used in swine diets for a long time, its inclusion levels have been limited due to concerns regarding its nutritive value primarily arising from results of early studies showing negative effects of dietary canola meal inclusion in swine diets. Such effects were attributable to the presence of anti-n...

Replacing Conventionally Processed Soybean Meal with Extruded/Expelled Soybean Meal in Swine Diets

Using Extruded-Expelled Soybean Meal in Swine Diets

Jason Woodworth, Graduate Research Assistant Extrusion processing is an effective means of improving the nutritional value of whole soybeans fed to swine. Recently, Insta-Pro International has combined extrusion technology with expelling, an oil extraction process, to produce an extruded-expelled soybean meal (Insta-Pro ExpressTM extruder/press system). The resulting soybean meal contains sligh...

Bioavailability of phosphorus in meat and bone meal for swine.

Meat and bone meal (MBM), when supplemented with tryptophan, is an excellent protein source for pigs. It is also a rich source of Ca and P, but some research has suggested that the bioavailability of P is variable. Experiment 1 further examined the bioavailability of P in MBM. The MBM was obtained directly from a plant and was processed to pass through a 10-mesh screen. It contained 50.7% CP, 2...
