Effects of using soy protein concentrate as a protein source in diets fed to weanling pigs

Because of the presence of antinutritional factors, the use of soybean meal in weanling pig diets is limited. Animal protein sources can be used, but their cost is high relative to plant protein sources. Therefore, it is economically advantageous to find high quality plant protein sources that weanling pigs can tolerate.

Soybean meal can be processed in various ways to remove or reduce antinutritional factors. One way is to use an alcohol extraction process to remove water-soluble carbohydrates, followed by heat treatment. This process produces soy protein concentrate. An experiment was conducted to determine effects of feeding a soy protein concentrate product called X-SOY 200 on growth performance and blood parameters in weanling pigs.

Digestibility of energy and concentrations of DE and ME in soy protein concentrate with different particle sizes fed to weanling pigs

Soy protein concentrate is produced by aqueous ethanol extraction of water-soluble carbohydrates from soybean meal, followed by heat treatment. The ethanol extraction process removes soluble carbohydrates, leaving a product that contains at least 65% crude protein (dry matter basis). Because soy protein concentrate contains reduced levels of oligosaccharides, trypsin inhibitors, and lectins compared with conventional soybean meal, it can be used in diets for weanling pigs.

Amino acid digestibility in soy protein concentrate with different particle sizes fed to weanling pigs

Soy protein concentrate is produced by aqueous ethanol extraction of water-soluble carbohydrates from soybean meal, followed by heat treatment. The ethanol extraction process removes soluble carbohydrates, leaving a product that contains at least 65% crude protein. Because soy protein concentrate contains reduced levels of oligosaccharides, trypsin inhibitors, and lectins compared with conventional soybean meal, it can be used in diets for weanling pigs.

Reducing the particle size of soybean meal can increase amino acid digestibility due to the increased surface area for enzymes to work on. However, there are no known data on the effect of particle size on amino acid digestibility in soy protein concentrate. Therefore, an experiment was conducted to determine the digestibility of crude protein and amino acids in soy protein concentrate ground to three different particle sizes and to compare these values to values for soybean meal and fish meal when fed to weanling pigs.

Effects of full fat or defatted rice bran on growth performance of weanling pigs

Rice bran is the brown outer layer of brown rice, which is removed from brown rice to produce white polished rice for human consumption. Rice bran may be full fat, containing 14 to 25% fat, or defatted, which reduces the concentration of fat to less than 5%.

Rice bran has a high concentration of non-starch polysaccharides (NSP), primarily arabinoxylan and cellulose. NSPs decrease nutrient digestibility and thus limit the inclusion of rice bran in weanling pig diets. Recent data from our laboratory indicate that adding exogenous xylanase to diets containing full fat rice bran (FFRB) or defatted rice bran (DFRB) increases the concentrations of digestible and metabolizable energy. The objective of this experiment was to determine the effects of increased inclusion levels of FFRB or DFRB to diets without or with exogenous xylanase on growth performance.
