Abstract:

Objetivou-se avaliar a qualidade de silagem de genótipos de milheto produzidas com e sem inoculante bacteriano. O experimento foi conduzido no Campus da Faculdade de Agronomia da Universidade de Rio Verde. O delineamento experimental utilizado foi de blocos ao acaso, com quatro repeti es, em esquema fatorial 5 x 2, sendo, cinco genótipos de milheto: ADR 500, ADR 7010, LAB 0730, LAB 0731 e LAB 0732 e dois tratamentos: com e sem adi o de inoculante bacteriano. Os resultados demonstraram que as silagens produzidas com os novos genótipos de milheto, podem ser consideradas de boa qualidade. Contudo, a adi o do inoculante bacteriano n o teve efeito consistente sobre a qualidade das silagens, no que diz respeito aos teores de matéria seca, proteína bruta, hemicelulose e valores de pH. Apenas as fra es fibrosas sofreram altera es com a adi o do inoculante nos genótipos de milheto. The objective was to evaluate the quality of silage produced from millet genotypes with and without inoculants. The experiment was conducted on the campus of the Agronomy Faculty of Rio Verde University. The experimental design was a randomized block design with four replications in a factorial 5 x 2, with five pearl millet genotypes: ADR 500, ADR 7010, LAB 0730, LAB 0731 and LAB 0732 and two treatments: with and without addition of inoculants. The results showed that the silage produced from new genotypes of pearl millet can be considered of good quality. However, the addition of the inoculant had no consistent effect on the silage quality, considering dry matter, crude protein, hemicellulose and pH values. Only the fibrous fractions were modified with the addition of the inoculant in pearl millet genotypes.
