Animal proteins may not fill the gap
Direct feeding of creatine in modern
poultry production, however, is problematic,
even for producers using animal protein
products. An investigation on natural
creatine sources for poultry nutrition revealed that even meat meal, fishmeal and
other animal derived proteins are very low
and highly variable in their creatine content.

The likely reason for this is that creatine is not stable in high heat and high moisture conditions, the two most
common processes applied in the production of animal proteins. Finished feed for broilers and turkeys is almost
universally pelleted in some markets, again introducing high heat and moisture. Therefore, direct addition of
creatine is a poor candidate for
creatine enrichment of animal feed.

AlzChem has perfected the production of a non-hygroscopic, free-flowing GAA marketed as Creamino.
Creamino, which contains 96% GAA, has been shown to increase muscle creatine levels more than 20%
when fed as directed.
Feeding Creamino also spares the

Feeding trials with Creamino have
shown beneficial effects in broiler
performance compared to All-veg and animal protein containing diets. Based on this study, it might be concluded
that indeed creatine may have been limiting for bird growth even with fishmeal in the diet.

Creamino: Energy for healthy growth
A combination of reduced dietary creatine and increased muscle mass may challenge the ability of broilers and
turkeys to produce enough creatine for optimal growth from de novo synthesis. GAA is readily converted to creatine in the body. Creamino contains a guaranteed level of GAA in a flowable, non-hygroscopic, virtually dust-free
formulation which holds up pelleting temperatures. Creatine is absent from animal protein-free diets and is at a
low, undependable, level even in diets that contain animal proteins. Feeding trials demonstrate improvements in
bird performance from Creamino as a source of creatine. Together, these facts suggest that creatine is at least
part of the missing link for healthy growth in animal protein-free diets and diets with low creatine content.
Creamino is the only feed additive specifically designed for and approved as a source of creatine
in animal feeds.
