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.
