Resumo: Two experiments were conducted aiming to: 1) evaluate the combination of Lactobacillus buchneri + Lactobacillus hilgardii and Lactobacillus buchneri + Lactobacillus plantarum in the ensiling of reconstituted corn grains and their effects on silage fermentation, nutritional value, and aerobic stability of the silage and the supplement made with these silages; 2) to determine the impacts of providing fresh and exposed reconstituted corn grain silage supplements on the intake and performance of pasture-finished Nellore cattle with high supplementation. Experiment one evaluated reconstituted corn grain silages non-inoculated and inoculated with L. buchneri + L. hilgardii both in concentration of 1.5 x105 cfu/g and L. buchneri + L. plantarum at 2 x105 cfu/g and 1 x105 cfu/g respectively, stored for 60 days and supplements for beef cattle using these silages. Inoculated silages presented a higher number of lactic acid bacteria, pH and aerobic stability (P < 0.01) and lower number of yeast (P < 0.01) in comparison to non-inoculated and did not differ between both inoculated (P > 0.01). Treated supplements had higher aerobic stability and lower yeast and mold counts than control supplement and did not differ between them. In experiment 2, 70% of dry rolled corn was substituted to reconstituted corn grain silage. Cattle consuming reconstituted corn grain silage supplement until 6 days of aerobic exposure had higher average daily gain and final body weight (P ≤ 0.06) tended to consume less supplement (P ≤ 0.09) and were more efficient in putting weight per kg of dry matter ingested (P ≤ 0.04). Aerobic exposition had no linear effect and did not impact cattle performance in comparison to fresh supplement. Inoculation with L. buchneri + L. hilgardii or L. buchneri + L. plantarum guarantee aerobic stability for 9 days in silage and for 6 days in supplement under laboratory conditions. Cattle consuming reconstituted corn grain silage supplement exposed until 6 days had better performance than cattle consuming dry corn supplement.

O experimento um avaliou silagens de grãos de milho reconstituídos não inoculadas e inoculadas com L. buchneri + L. hilgardii ambas na concentração de 1,5 x 105 ufc/g e L. buchneri (2 x 105 ufc/g) + L. plantarum (1 x 105 ufc/g) armazenadas por 60 dias, e suplementos para bovinos utilizando essas silagens. As silagens inoculadas apresentaram maior número de bactérias ácido lácticas, pH e estabilidade aeróbia (P < 0,01) e menor número de leveduras (P < 0,01) em comparação a silagem não inoculada, não diferindo entre silagens inoculadas (P > 0,01). O suplemento com silagem inoculada apresentou maior estabilidade aeróbia e menor contagem de leveduras e fungos do que o suplemento controle, e não diferiu entre eles. No experimento 2, 70% de milho seco moído foi substituído por silagem de grãos de milho reconstituídos. Os bovinos consumindo suplemento de silagem de grãos de milho reconstituídos por até 6 dias de exposição aeróbia apresentaram maior ganho médio diário e peso corporal final (P ≤ 0,05), tenderam a consumir menos suplemento (P ≤ 0,09) e foram mais eficientes em ganhar peso por kg de matéria seca ingerida. A exposição aeróbica não teve efeito linear e não impactou o desempenho dos bovinos em comparação com o suplemento fresco. A inoculação com L. buchneri + L. hilgardii ou L. buchneri + L. plantarum garante estabilidade aeróbica da silagem por pelo menos 9 dias e por 6 dias no suplemento em condições de laboratório. Os bovinos consumindo suplemento de silagem de grãos de milho reconstituídos expostos por até 6 dias tiveram melhor desempenho do que os bovinos consumindo suplemento com milho moído.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FAPESP: 2022/08742-5CNPQ: 130049/2022-0Universidade Estadual Paulista (Unesp)Siqueira, Gustavo RezendeSaulo Teixeira Rodrigues de Almeida2024-06-18T16:45:31Z2024-06-18T16:45:31Z2024-05-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfALMEIDA, S.
