Alternative food for broiler chickens: an overview

Resumo

This work presents an approach on alternative foods found today for broilers, since the addition of these in the nutrition of these birds is extremely advantageous, because it reduces dependence on commodities, such as soybeans and Corn. From research carried out, we have more prominently the foods cited in this work as, bran and sunflower pie, coconut bran, chestnut bran, almond and cashew pulp, manioc shavings, sugar cane yeasts and baking waste. For some authors the bran and sunflower pie have the problem of having low lysine content; its fiber and protein content is between 25% to 26% gross fiber and 29% to 42% of crude protein. His dietary addition ranges from 5%, 18% and 20% based on the age of the birds. The coconut bran has in its constitution protein content around 20% to 25% and gross fiber: 10% to 12%, for having high amount of oil may have problems with decomposition, but works showed that up to 20% did not significantly damage the performance Of the birds has not altered the housing characteristics. Just like the coconut bran, the chestnut bran has good indications for animal feed. Cassava zest is highly carbohydrate-rich, mainly starch-like, which characterizes it as an energetic food, an important source of energy, an essential component of chicken feed. The yeast extract promotes desirable performance and proper functioning of the intestinal mucosa, and consequently in the absorption of nutrients, this is explained due to the yeast extract containing free amino acids that participate in the Division and Growth Cellular in the immune system and help maintain animal health. It is therefore concluded that alternative foods are an excellent alternative to the use in broiler diets, however the pioneering foods should not be completely replaced, in view of the digestibility of most foods Alternative is low, which decreases the animal performance at the end.
