The following is what I copied off of the Envigo website describing why soy products aren’t desirable in a rodent diet.
“Formulated to exclude soybean meal, thus minimizing the presence of isoflavones, the primary type of phytoestrogen found in lab animal diets.”
The 2016 diet does not contain any animal by products, either.
I personally have used the 2018 for boo balls for my wilds for years and recently switched to the 2016. I just figured that it might be good to not overload their systems with the phytoestrogens.
