Alimentos alternativos fibrosos para galinhas caipiras: uma revisão

Abstract

Over the years, the consumer market has become more demanding when it comes to healthy food and with low concentrations of chemical residues. However, the demand for free-range products has increased, since one of the strongest images correlated to free-range farming is the fact that the animals have access to a green area, have a diet free from the use of growth promoters and synthetic enzymes and amino acids that can increase the digestibility and digestive efficiency of the animals. The challenge in raising free-range chickens is to make production more efficient by reducing feed costs, without losing the characteristics of their products. In the raising of free-range chickens, it is necessary to know more about the potentialities of using fibrous alternative feed, taking into consideration limiting factors, allowed inclusion levels, and productive feasibility. In view of the above, the objective of this review was to address the use of fibrous alternative feed that can be used in the diet of free-range chickens.
