The objective of this work was to evaluate the effect of the levels of lactic and propionic acids on in vitro fermentation of ruminal microorganisms. In experiment 1, the levels, in a total of 12 were the following: addition of 0 (control 1), 50, 100, 150, 200 and 250 mM of lactic acid and 0 (control 2), 50, 100, 150, 200 and 250 mM of propionic acid, respectively, in incubation flasks, which contained ruminal inoculum, glucose and synthetic culture medium, […]

The objective of this trial was to evaluate chemical and bacterial additives on inhibition of ethanol production, reduction of DM losses and on in vitro digestibility improvement of sugar cane silages. Treatments were (wet basis): without additive – control; urea – UR – (0.5; 1.0; 1.5%), NaOH (1; 2; 3%), calcium propionate – PROP – (0.05; 0.1; 0.2%), sodium benzoate – BENZ – (0.05; 0.1; 0.2%), potassium sorbate – SORB – (0.015; 0.03; 0.045%), Lactobacillus plantarum – PLA – (1 […]
