Watch the trypsin inhibitors if you want your piglets to perform

Feed levels of trypsin inhibitors holds the key to piglet’s performance 

Choosing the right mix of nutritional ingredients in the diet is critically important to improve the post weaning feed intake for young piglets. A new study published in National Hog Farmer concludes that it is important to focus on the tolerable level of anti-nutritional factors as trypsin inhibitors in swine diets.

The immature gut of the piglet makes them especially sensitive to even low levels of anti-nutritional factors in soybean meal. Trypsin inhibitors (TI) are major anti-nutritional factors and are a natural part of soybeans which inhibits the enzymes that digest protein and decreases performance.  Fortunately, TI can be removed when processed with higher temperatures because of their heat liability.

The study from National Hog Farmer shows that the level of TI in soybean co-products should be based on their TI-activity to secure high-performance in the starter feed, so it matches the level piglets tolerate. 

With the right level of TI in the starter feed the young piglets perform better via increased voluntary feed intake and better digestion of the protein.

HP 300 from HAMLET PROTEIN is a specialty soy protein with a high protein digestibility and a minimum level of anti-nutritional factors (eg. trypsin inhibitors).
