Avaliação e otimização de silagens de Manihot pseudoglaziovii Pax & Hoffman Euphorbiaceae com ou sem emurchecimento conservadas sob diferentes período de armazenamento

Abstract

This study had the objective classifying exclusive silages of maniçoba in according its referred desirability index gained from chemical and microbiology analyzes. The variables were dry matter, crude protein, neutral and acid detergent fiber, lignin, ash, soluble carbohydrates, pH, buffering capacity, epiphytic micro flora and aerobic stability. It was used the entirely randomized design composed by two fixed factors (2-level wilting and 3-level storage), totalizing six treatments and four replicates, both analyzed conform GLM procedure and numerical optimization in according actual literature. In all variables the wilting or and post conservation showed significant differences. It was gained silages with aerobic stability varying from 48 thru 240 hours. The wilted maniçoba silages had the best quality showing optimal values for storage of 87.77 and 82.33 days, respectively; as well as desirability index equals 1.00.
