The BCAAs (isoleucine, leucine and valine) are now available commercially and were added to a basal corn/soya lactation feed at 1.535 and 3.07%.
The additional amino acids significantly increased piglet milk consumption.
This resulted in major increases in piglet weight (P<0.001) and sows lost significantly less weight (P<0.001).
Piglet mortality was reduced (P=0.02).
To our knowledge, this is the first study demonstrating effects of dietary supplementation with a mixture of BCAAs (without increasing dietary protein levels) on the lactational performance of lactating sows and associated effects on the enhanced growth and reduced mortality of pre-weaning piglets, as compared to an isonitrogenous control. This looks an exciting area for further investigation.
