BIOTIN FOR POULTRY: AN ESSENTIAL BUT EXPENSIVE VITAMIN
Most authorities recommend adding a purified
source of d-biotin in most poultry feeds through the
use of the usual vitamin premix. The amount added
(without taking into account natural ingredients) is
a matter of discussion, because as we have already
seen, biotin is very expensive. My personal preference, based on literature review and commercial
experience, is adding 0.1 mg/kg biotin in all broiler
and layer diets based on corn, and double this
amount in diets based on wheat. Perhaps this is an
overindulgence, but wet litter is a common problem
in broilers and nowadays an ever bigger one with
cage-free layers. It is also prudent to review such
recommendations when alternative protein sources
are used, but again, we have such limited and outdated information on biotin requirements and bio-

availability that it is best to err towards the safe side.

Biotin is a significant vitamin
Biotin is a significant vitamin because it holds
a central role in nutrient metabolism, but it is only
needed in miniscule amounts. Most natural ingredients do not contain enough biotin, and wheat is
virtually devoid of bioavailable biotin. Thus, biotin
must be supplied through premixes, but its enormous cost warranties vigilance against low-cost
products. ■
