The authors apologise for two errors in their article.
On page 8, Alexander Doring is mistakenly referred to as the President of FEFAC. He is in fact the Secretary General of FEFAC.
And one of their references contains an error:
Feed Stuffs. (2014) Feed Marketing and Distribution in: Feed Additive Compendium (pp. 3–18). MN.
It should read:
Feedstuffs. (2014) Feed Marketing and Distribution In: Feedstuffs Reference Issue and Buyer's Guide (pp 3–18). Bloomington, MN.
