Nutrition pre and post-hatching in poultry

Abstract

This study aimed to expose the features, advantages and disadvantages of nutrition pre and post-hatching poultry. In poultry several techniques have emerged with the aim of improving the production of birds from laying eggs until the slaughter of animals. Among these techniques nutrition pre-hatching is a promising concept that aims to provide the embryo in the egg even greater amount of nutrients, which can lead to a better performance of the animals after hatching. Already nutrition after hatching aims to provide the animal newly hatched quick access to food to accelerate intestinal maturation both morphologically and physiologically to prevent any irreversible losses in animal performance. The nutrition pre-hatching even as a promising concept, presents conflicting results, perhaps due to the application technique due to the nutrient or nutrients applied or the application level, necessitating more work is being done in this area. Nutrition after hatching has been shown effective in early maturation of the gastrointestinal tract that even now born anatomically complete, quick access to solid food accelerates the maturation process, leading to a quickly evolution of enterocytes and increased production of digestive enzymes.
