If you reduce the content of soybean meal in your starter feed, be careful what you replace it with!

We have recently highlighted the need to reduce the content of soybean meal (SBM) in broiler starter diets below 30% in order not to exceed the upper limits of antinutritional factors (ANFs) that can compromise the intestinal health and the productive performance of chickens (Blanch 2020 a, b; Blanch 2021).

In short, reducing the level of SBM meal in chicken starter diets is becoming a common practice in modern poultry production. We must be very aware of the type of protein source that we use to fill the void left by that SBM reduction in the feed formula. Our objective should be to minimize the amount of ANFs without giving up having a good supply of protein and amino acids.
