Resumo: We aimed to evaluate nutritional quality, fermentation profile, aerobic stability, and dry matter losses in corn (Zea mays) and wheat (Triticum aestivum 'BRS Umbu') silages. Treatments included uninoculated and inoculated (Lactobacillus plantarum and Pediococcus acidilactici, 1.0 × 105 UFC g-1) wheat silage, corn silage from a conventional hybrid and a transgenic hybrid. Nutritional quality and fermentation profile variables were tested in a completely randomized design. Means were compared using Tukey’s test at 5% significance. An aerobic stability trial was conducted in a factorial design with two silages (wheat × inoculated wheat; conventional hybrid corn × transgenic hybrid corn) and two temperatures (ambient temperature × controlled temperature at 24°C). Data were submitted to ANOVA and means were analyzed by the F test at 5% probability. Inoculation of wheat silage increased dry matter, organic matter, and total carbohydrates, but reduced crude protein by a dilution effect. Regarding the fermentation profile, inoculation reduced acetic acid and butyric acid content, whereas it increased propionic acid in wheat silage. Bt corn hybrid silage showed higher dry matter and lower neutral detergent fiber, whereas transgenic corn silage showed lower content of acetic acid, propionic acid, alcohol, and ammonia. Conversely, Bt hybrid silage showed higher butyric acid. Transgenic corn silage showed higher temperature than the conventional hybrid silage during aerobic exposure. Inoculated wheat silage experienced larger deterioration and dry matter losses during the aerobic stability trial. Temperature control worsened aerobic stability in all treatments, increasing dry matter losses and heating.

Os tratamentos foram a silagem de trigo sem inoculante, silagem de trigo com inoculante bacteriano (Lactobacillus plantarum e Pediococcus acidilactici na concentração de 1,0×105 UFC g-1), silagem de milho convencional e silagem de milho transgênico. Para as variaveis relacionadas a qualidade nutricional, assim como perfil fermentativo o delineamento utilizado foi o inteiramente casualizado e as médias foram analisadas pelo teste Tukey ao nível de 5%. Já com relação a estabilidade aeróbia, o delineamento estatístico foi o inteiramente casualizado, em esquema fatorial, sendo 2 silagens (silagem de trigo × silagem de trigo com inoculante; silagem de milho convencional × silagem de milho transgênico) e 2 ambientes em avaliação (temperatura ambiente × temperatura controlada à 24 °C). Os dados coletados foram submetidos à análise de variância e as médias foram analisadas pelo teste F ao nível de 5%. A inoculação da silagem de trigo promoveu maior conservação de matéria seca, matéria orgânica e carboidratos totais, levando a redução da concentração de proteína bruta, por efeito de diluição, quando comparada a silagem controle. A silagem de trigo inoculada apresentou os teores reduzidos de ácido acético e butírico, porém teor mais elevado de ácido propiônico. Houve maior concentração de matéria seca e menor teor de fibra em detergente neutro para a silagem de milho Bt. A silagem de milho transgênico apresentou menores teores de ácido acético, ácido propiônico, álcool e amônia e teor de ácido butírico mais elevado. A inoculação da silagem de trigo aumentou a deterioração da massa ensilada após exposição ao ar, o que elevou as perdas de matéria seca. Para as silagens de milho, a máxima temperatura observada foi registrada na silagem de milho transgênico. O controle ambiental influenciou negativamente aumentando as perdas de matéria seca e reduzindo a estabilidade de ambas as silagens.UEL2018-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2727510.5433/1679-0359.2018v39n1p253Semina: Ciências Agrárias; Vol. 39 No. 1 (2018); 253-260Semina: Ciências Agrárias; v. 39 n. 1 (2018); 253-2601679-03591676-546Xreponame:Semina.
