Soybean Meal May Boost Faster Pig Growth

Recent work published by researchers at Kansas State University suggests that increasing the percentage of soybean meal in swine diets may result in higher-than-expected energy levels in nursery pigs, reportsUSSoy.org.

The studywas based on feeding 2,200 mixed-gender nursery pigs varying amounts of soybean meal over a 21-day period. The findings of those pigs fed soybean meal were then compared with energy levels commonly found in corn diets.

“For a long time soybean meal has been thought to provide about 78% (of) the energy value as corn,” says Bob Goodband, a swine nutritionist with K-State Research and Extension. “So it hasn’t been thought of as a significant source of energy. What we found was that feeding increasing amounts of soybean meal increases the net energy value to approximately 105% and 121% of the energy provided by corn.”

Goodband notes that soybean meal is the primary plant protein source for swine diets in the United States. Soybean meal is a good source of amino acids, which are important for building protein and muscle growth in swine.

By changing the amount of soybean meal in swine diets, the K-State researchers were essentially trying to find the energy value of soybean meal measured by its improvement in feed efficiency for those animals.
