Is there a Role of Essential Fatty Acids in Early Life Programming in Poultry
Nutrients pre-packaged in the egg by the hen serve as the early diet to the chick embryo during incubation.Fatty acids in the egg are of considerable importance to the chick embryo due to their diverse roles in energy, polyunsaturated fatty acid (PUFA) and eicosanoid metabolism.To investigate the effects of early exposure to essential fatty acids and its impact on progeny chicks, an in ovo method or ”feeding the embryo” through maternal or hen diet was conducted.Early access to n-3 or n-6 PUFA through maternal diet alters cell membrane PUFA profile, eicosanoid production, cellmediated immunity, and gene expression.These results suggest that essential fatty acid metabolism during growth in broiler birds can be programmed by the balance of n-6 and n-3 PUFA in the maternal diet.Therefore, feeding the embryo or ”early diet manipulation” offers a powerful and holistic tool to promote the health of hatchlings in a natural and sustainable way.As the days to reach market weight in modern birds continue to decrease, the potential of early life programming in promoting health,welfare and productivity warrants further investigation.
