Digestibility of phosphorus in a novel source of soy protein concentrate and in soybean meal fed to weanling pigs

Soy protein concentrate is produced by extracting some of the non-protein components of soybean meal, including soluble carbohydrates, from soybean meal. These soluble carbohydrates include oligosaccharides, which reduce the tolerance of young pigs to conventional soybean meal. With the oligosaccharides removed, soy protein concentrate can be used as a source of protein in diets for weanling pigs.

Most soy protein concentrate is produced using an alcohol extraction process. However, a new source of soy protein concentrate called Nutrivance (Midwest Ag Enterprises Inc., Marshall, MN) has recently been introduced, which uses a process combining non-alcohol extraction and enzymatic treatment of soybean meal. An experiment was conducted to determine the apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of phosphorus in this new ingredient.

Effects of production area and microbial phytase on the apparent and standardized total tract digestibility of phosphorus by growing pigs

The area in which soybeans are grown is known to affect various aspects of the chemical composition of soybean meal produced from those soybeans. However, it is not known if there is a difference in the concentration of phytate, and therefore in phosphorus digestibility, among soybeans from different growing areas. Therefore, an experiment was conducted to determine the concentration of phytate and the apparent (ATTD) and standardized (STTD) total tract digestibility of phosphorus in soybean meal produced from soybeans grown in four different areas in the United States. A secondary objective was to determine the effect of microbial phytase on STTD of P in soybean meal from each of the four areas.

Effect of Sal CURB® on digestibility of energy, amino acids, calcium, and phosphorus in growing pigs

Porcine epidemic diarrhea virus (PEDV) can be spread via contaminated feed. Treating PEDV-contaminated feed with formaldehyde has been shown to prevent infection in pigs that consume the feed. However, concerns have been raised about the effect of treatment with formaldehyde on the nutritional value of feedstuffs. Therefore, an experiment was conducted to determine the effects of adding a formaldehyde-based feed disinfectant to the diet on the apparent ileal digestibility (AID) of dry matter, crude protein, and amino acids, and the apparent total tract digestibility (ATTD) of dry matter, gross energy (GE), calcium, and phosphorus in nursery pigs.

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.
