Abstract
The genetically improved modern commercial layers are capable of
producing 330 eggs in their productive life of up to 72 weeks. The journey of genetic
improvement continues and the breeding companies now developed ‘long life’ layers
that can lay 500 eggs in 100 weeks of age. The changing production dynamics of layer
chicken calls for better understanding of nutrient requirements and good nutritional
programming. Prediction models are being used to assess the nutrient requirements
of the hybrid layers; while, precision feeding of quantity of feed and or nutrients can
lower feed costs and ensures more predictable bird performance. In-ovo and early
chick nutrition give jump start at juvenile stage of chicken. The idea of split feeding,
although beneficial in certain production parameters, suffers the disadvantages of
additional infrastructure and workforce requirements. The nutritional programme for
egg size, shell quality and feeding for value added designer egg production is aimed
at increasing the profit to the farmers. In recent days, feeding for healthy gut that
enables efficient digestion and absorption of nutrients has also gained paramount
importance. The concept of feed nanotechnology can help in increasing nutrient
availability and environment protection; while, phytogenic products can some
extent replace the role played by antibiotic growth promoters. The advancements in
biotechnology has opened up not only numerous opportunities for the development
of products and technologies for poultry feeding, but also to study the influence of
nutritional factors on genomics, proteomics and metabolomics.
