Abstract
Inovo feeding is a viable technology that facilitates extra nutrient deposition into chickens between
the late-term embryo stage to early post-hatch period, meant to deliberately promote development
of gastrointestinal tract and strengthen the immune system Continous changes in climatic condition globally has caused an out-play of extreme weather
conditions, culminating into heat-stress, experienced by man and livestock. Heat stress (HS) results
into an increase in production and activity of reactive oxygen species, which negatively impact the
physiological mechanism and hatchability of chickens. Inovo feeding of chickens with
phytonutrients and plant products has been reported to improve their defenses against various
diseases like contagious bursal disease, influenza virus and new castle disease. Restricting chicken
embryos the access to extra nutrient supply, at the later stage of development may prevent freshly
hatched chicks from growing and developing into their full potential.
