Does your piglet feed overestimate protein digestibility?

Article by Carsten Pedersen, PhD, nutritionist

New meta-analysis suggests typical feed formulations use the wrong values.

Protein digestibility is a primary concern when formulating feed for weaned piglets. But the fact is that most current formulation practices don’t get it right. The reason is that they use digestibility values based on growing and finishing pigs – and, in doing so, over-estimate the digestibility of raw materials in younger animals.

To evaluate age-related differences in nutrient digestibility, HAMLET PROTEIN and the Department of Animal Sciences at the University of Illinois teamed up to conduct a meta-analysis of standardized ileal digestibility (SID) data published in 1998-2013.

All the data collected for the analysis covered soy-based ingredients for piglet starter feed. It is clear from the analysis that pig weight does have an impact on the SID of protein and amino acids.
