The effect of standard and large pellet creep feed on the performance and blood parameters of weanling pigs

Jul 21, 2025

Jen-Yun Chou, Kylie Kallal, Abigail Tillotson – It is recommended that diets designed for young pigs should include less carbohydrates and lysine and more fibre to minimise insulin spikes. High fibre ingredients typically contain higher iron levels compared to more protein-concentrated feeds, directly benefiting anaemic piglets. In this study, off-the-shelf and affordable large pellet diets (high in fibre) were tested and compared to a standard creep diet (Phase 1 nursery diet) to determine which diet piglets prefer. A mixture of standard creep and large pellets was also provided to determine if providing a more varied diet can improve creep consumption. The main objective was to determine if large pellet feed would increase creep consumption and improve piglets’ weight gain and blood iron status at weaning.

Results showed that piglets show equal preference for a large pellet creep (4cm pellet) and crumble starter diet. An off-the-shelf high fibre pellet feed (E17 horse feed) did not improve piglet growth or blood measures. Large piglets showed signs of anaemia at weaning compared to smaller littermates.

For over two decades, Dr. Mitloehner has been at the forefront of research on how animal agriculture affects our air and our climate. With deep expertise in emissions and volatile organic compounds, his work initially focused on air quality in regions like California’s Central Valley—home to both the nation’s richest agricultural output and some of its poorest air quality.

In recent years, methane has taken center stage in climate discourse—not just scientifically, but politically. Once a topic reserved for technical discussions about manure management and feed efficiency, it has become a flashpoint in debates over sustainability, regulation, and even the legitimacy of livestock farming itself.
