Resumo: The objective of this study was to evaluate the chemical composition and the fermentative variables of different maize hybrids and their interference in the aerobic stability of silage. The hybrids used were the Maximus VIP3, Defender VIP and Feroz VIP, being simple, triple and double hybrids, respectively. The chemical composition and the aerobic stability were evaluated 60 days after the silos were sealed. One kilo of sample from each replicate was placed in polypropylene containers lined with plastic bags and transferred to a climatic chamber at 25 ± 2°C, and the silage temperatures were measured three times a day for seven days. In the chemical composition, only the fraction A of the non-fibrous carbohydrates presented a difference between the treatments. The Maximus VIP3 hybrid was superior in relation to the others for acetic acid production and did not differ from the Defender VIP hybrid in lactic acid concentration. A longer time was required for the Maximus VIP3 silage temperature to increase by 2°C (125.3 hours), while the other silages did not differ significantly (53.3 and 45.3 hours for Defender VIP and Feroz VIP). The hybrid Maximus VIP3 is recommended for silage production due to its characteristics, including a high concentration of sugars and a greater aerobic stability.

Os híbridos utilizados foram o Maximus VIP3, Defender VIP e Feroz VIP, sendo híbridos simples, triplo e duplo, respectivamente. A composição química e a estabilidade aeróbia foi avaliada 60 dias após a vedação dos silos. Amostras de um quilo foram colocadas em recipientes de polipropileno revestido com saco plástico e transferidos para câmara climática à temperatura de 25 ± 2 °C, e as temperaturas das silagens foram medidas três vezes ao dia durante sete dias. Na composição química, apenas a fração A dos carboidratos não fibrosos apresentou diferença entre os tratamentos. O híbrido Maximus VIP3 foi superior em relação aos demais para produção de ácido acético, e não diferiu do híbrido Defender VIP na concentração de ácido lático. Tempo significativamente mais longo foi necessário para que a temperatura da silagem de Maximus VIP3 aumentasse em 2°C (125,3 horas), enquanto as outras silagens não diferiram entre si (53,3 e 45,3 horas para Defender VIP e Feroz VIP). O híbrido Maximus VIP3 apresentou alta concentração de açucares e maior estabilidade aeróbia, sendo recomendado para produção de silagem pelas suas características.Sociedade de Ciências Agrárias de Portugal2020-01-29T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.17723eng2183-041X0871-018XHorst, Egon HenriqueBumbieris Junior, ValterNeumann, MikalSouza, AndréStadler Junior, EdelmirDochowat, Andréinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:25:16Zoai:ojs.revistas.rcaap.pt:article/17723Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:31:19.715051Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
