Abstract: Foram estudados os efeitos de três inoculantes microbianos, na silagem de sorgo (Agroceres 2005), em 16 silos experimentais, confeccionados a partir de baldes plásticos portando válvulas. O sorgo, cortado aos 97 dias de crescimento (35,9% de MS), foi homogeneizado e submetido a quatro tratamentos, com quatro repeti es: controle, Sil-All (Streptococcus faecium, Pediococcus acidilactici, Lactobacillus plantarum, amilase, hemicelulase e celulase), Silobac (L. plantarum, S. faecium e Lactobacillus sp) e Pioneer 1174 (S. faecium e L. plantarum). Os silos foram abertos após 120 dias para análise da composi o bromatológica e perfil fermentativo. Os três inoculantes diminuíram o teor de MS e aumentaram a concentra o de etanol e as perdas de MS, em rela o ao grupo controle. O Sil-All aumentou o teor de FDN, em rela o ao grupo controle, e diminuiu a concentra o de amido, em rela o ao Silobac, enquanto que o Pioneer 1174 diminuiu a estabilidade aeróbia, em rela o ao grupo controle. N o foram observados efeitos sobre os teores de PB, NIDA, carboidratos solúveis, FDA, lignina, hemicelulose, celulose, a digestibilidade in vitro da matéria seca, o poder tamp o e as concentra es dos ácidos acético, propi nico, butírico e lático, bem como sobre o pH ou sobre as concentra es de nitrogênio amoniacal.

Abstract: Os resultados obtidos com a inocula o microbiana de diferentes plantas forrageiras, para a produ o de silagens, têm apresentado resultados conflitantes. Objetivou-se, com o presente estudo, avaliar os efeitos da inocula o microbiana da planta de milho, para a produ o de silagem, sobre a digestibilidade total em carneiros. Oito carneiros machos e castrados foram distribuídos em um delineamento em cross-over, com dois períodos sucessivos (8 animais/tratamento), e os tratamentos corresponderam à silagem de milho controle (média de 28,6% de MS e 9,6% de PB) ou sob efeito da inocula o com o produto Pioneer 1174 (Streptococcus faecium e Lactobacillus plantarum). Cada período experimental teve dura o total de 21 dias, sendo os cinco últimos destinados à coleta de fezes e urina. A inocula o n o alterou a digestibilidade total da MS (inoculada = 64,5% vs. controle = 64,6%), PB (56,0% vs. 54,4%), ENN (69,2% vs. 70,2%), FB (56,3% vs. 54,6%), FDN (49,0% vs. 52,2%), FDA (48,2% vs. 48,6%), amido (98,8% vs. 98,7%), NDT (65,1% vs. 65,1%), reten o nitrogenada (0,59 vs. 0,65 g de N/animal/dia) ou consumo de MS (2,13 vs. 2,28% do PV), mas tendeu (P=0,0878) em aumentar a digestibilidade do EE (86,7% vs. 85,0%). Os dados presentes n o permitem recomendar a inocula o da planta do milho com bactérias ácido-láticas para produ o de silagens.

Abstract: the results of using lactic acid bacteria in ensiling has been conflicting. this study was conducted to evaluate the effects of microbially inoculated corn plant for silage production on total digestibility in wethers. eight wethers were assigned to a cross-over design, with two periods (8 animals/treatment) and treatments were: control corn silage (28.6% dm and 9.6% cp, on average) or under inoculation with pioneer 1174 product (streptococcus faecium and lactobacillus plantarum). each period extended for twenty-one days, the last five used for feces and urine collection. the inoculation did not influence total digestibility of dm (inoculated = 64.5% vs. control = 64.6%), cp (56.0% vs. 54.4%), fne (69.2% vs. 70.2%), cf (56.3% vs. 54.6%), ndf (49.0% vs. 52.2%), adf (48.2% vs. 48.6%), starch (98.8% vs. 98.7%), tdn (65.1% vs. 65.1%), n retention (0.59 vs. 0.65 g of n/animal/day) or dm intake (2.13 vs. 2.28% of bw), but there was a tendency (p=0.0878) of increasing digestibility of ee (86.7% vs. 85.0%). present data does not support to recomend lactic acid bacteria for inoculation of corn crop for silage production.

Abstract: the corn hybrids ag 510 and ag 5011 (agroceres) were ensiled in plastic experimental silos (four units/treatment), consisting of eight treatments: control (without inoculation), sil-all? (s. faecium, p. acidilactici, l. plantarum, amylase, hemicellulase, and cellulase), silobac? (l. plantarum, s. faecium, and lactobacillus sp.), and pioneer 1174? (s. faecium and l. plantarum). silos were opened 106 days after ensiling and sampled to proceed chemical analyses. ag 510 and ag 5011 hybrids differed for dm (35.26 vs. 44.06%), cp (8.07 vs. 9.73%), adin (19.04 vs. 24.76% of total n), ndf (62.03 vs. 64.71%), adf (36.74 vs. 40.19%), lignin (11.24 vs. 12.57%), water soluble carbohydrates (12.0 vs. 7.0%), starch (27.04 vs. 24.46%), ph (3.79 vs. 4.32), amoniacal nitrogen (4.19 vs. 8.81% of total n), lactic acid (4.875 vs. 1.421% of dm) and acetic acid (1.269 vs. 2.682% of dm). pionner 1174? increased water-soluble carbohydrate in ag 510 hybrid, but not in ag 5011. inoculation with pioneer and silobac had the highest and the intermediate starch content, respectively, in relation to control and sil-all in the ag 510 hybrid, but not in ag 5011. ag 510 provided better fermentation pattern when compared to ag 5011, although inoculants showed no effects on those parameters.
