The literature which has contributed to our knowledge
base on early intestinal development in poultry
has been developed over the last 50 years. In the last
20 years, however, the application of more sophisticated
techniques to understanding intestinal physiology and
novel approaches to potentially modulating early intestinal
development (in ovo feeding) has accelerated
our interest in the multiple contributions the intestine
makes to the establishment of whole animal posthatch
homeostasis. This heightened interest has included inputs
from the realm of poultry management (immediate
versus delayed access to feed), microbiome development
(endogenous versus probiotics), and innate immunity
(maternal antibodies). The broiler and turkey industries
are already encountering constraints on the use
of antibiotics (possibly including ionophores), increased
reliance on anticoccidial vaccines, shortened and longer
production cycles (product dependent), and heightened
concerns with food safety. These challenges underscore
the continuing need for novel research ideas combined
with the integration of data that is already in the literature
to facilitating a healthy and robust intestine.
