ABSTRACT The objective of this study was to evaluate natamycin, Lactobacillus buchneri (LB), or their combination on the chemical composition, loss, fermentative profile, and aerobic stability as well as gas production and composition of sugarcane silages. The treatments were (wet basis): no additive (control), 10 g t−1 of natamycin (N10), 5 × 104 cfu g−1 of LB, and the combination of 4 g t−1 of natamycin and 2.5 × 104 cfu g−1 of LB (NLB). Sugarcane was chopped (10 mm), […]

The objective of this study was to evaluate the production practices and use of corn silage in dairy farms in Southern Brazil, and to evaluate their impact on the nutritional quality and occurrence of mycotoxins. The data were collected by application of questionnaires among the producers, and by analysis of silage samples. The variables were subjected to factorial analysis of data reduction through the principal components method, thus obtaining 84.12% of the variance associated with the location, corn hybrid, crop […]

Ensilagem é um método de preservação de uma cultura úmida. Uma cultura úmida pode favorecer o crescimento de vários tipos de microrganismos, sendo que a maioria pode degradar o valor nutricional do alimento para o gado. No entanto, a ensilagem geralmente controla a atividade microbiana pela combinação de um ambiente anaeróbio com a fermentação natural dos açúcares por bactérias do ácido lático presentes na cultura. Essa fermentação e a consequente redução do pH suprimem principalmente o crescimento de outros microrganismos […]
