Silagem de engaço de banana em dieta completa, sob diferentes proporções entre concentrado e brs capiaçu

Abstract

The use of agricultural residues in animal feed is gaining more and more space in Brazilian livestock farming. Aiming to reduce production costs and consequently reduce environmental impacts. In this context, we have the banana stem, which can be used in the production of silage as long as its composition provides adequate potential for fermentation and nutrition. With this in mind, the objective was to evaluate the fermentative profile and chemical chemical composition of banana stalk silage, integrated into a complete diet system, in different proportions between concentrate (soybean and corn meal) and BRS Capiaçu. A completely randomized design was used, with four treatments and five replications: control (stem only); diet 1 - 50% stem + 12.5% BRS Capiaçu + 37.5% concentrate; diet 2 – 50% stem + 25% BRS Capiaçu + 25% concentrate; diet 3 - 50% stem + 37.5% BRS Capiaçu + 12.5% concentrate; based on natural matter. The results were subjected to analysis of variance (ANOVA) and Tukey's test, adopting P <0.05 as the critical level. Banana stem silage has potential for animal feed, as long as moisture-sequestering additives are used, as in the present study through concentrate and BRS Capiçu, which were responsible for improving the fermentative profile of banana stem silage, reducing losses. during the process, in addition to improving its nutritional value for ruminants in general.
