Farelo de glúten de milho: alternativa na alimentação de galos

Abstract

There are many options to decrease the huge costs of production. Using alternative aliments, in order to substitute soybean bran and corn bran, which in their majority are by-products of agribusiness, is one of them. Corn Gluten Meal (FGM-21) is a by-product of corn processing, used to obtain oil and starch. In order to check the possibility of using corn gluten meal in the feeding of roosters and their effects on semen characteristics of those animals, 40 semi-heavy roosters were used, with initial age of 68 weeks, distributed at random in 40 boxes. Two treatments were used: T1 (Control) - corn and soybean bran meal and T2 - with addition of 10% corn gluten meal. For the analysis, it was made a collection per week, during 5 consecutive weeks. The following variables were evaluated: volume, motility and sperm concentration, membrane integrity, acrosome and DNA, besides body weight and feed intake. The results showed that there are no significant differences between the two treatments for the variables evaluated, allowing the addition of 10% corn gluten meal in feeding roosters.
