Última Accuracy, precision and robustness of different methods to obtain samples from silages in fermentation studies R. Bras. Zootec. Gomes,Rodrigo da Costa; Meyer,Paula Marques; Castro,Ari Luiz de; Saran Netto,Arlindo; Rodrigues,Paulo Henrique Mazza. The objective of this study was to evaluate accuracy, precision and robustness of two methods to obtain silage samples, in comparison with extraction of liquor by manual screw-press. Wet brewery residue alone or combined with soybean hulls and citrus pulp were ensiled in laboratory silos. Liquor was extracted by a manual screw-press and a 2-mL aliquot was fixed with 0.4 mL formic acid. Two 10-g silage samples from each silo were diluted in 20 mL deionized water or 17% formic acid solution (alternative methods). Aliquots obtained by the three methods were used to determine the silage contents of fermentation end-products. The accuracy of the alternative methods was evaluated by comparing mean bias of estimates obtained by manual screw-press and by...
