abstract: Fermentation products and changes in nonstructural carbohydrate fractions with ensiling were examined and related to the unfermented herbage characteristics of 1 Pennisetum americanum, 1 maize and 8 sorghum cv. The buffering capacity of unfermented herbage was found to be greater in sorghum (9.8 ml 0.1 M lactate) than in maize (8.0 ml 0.1 M lactate). Starch was less susceptible to degradation during fermentation than sugar. High levels of starch resulted in fermentation and loss of a smaller proportion of the total nonstructural carbohydrates (TNC). Reductions in TNC ranged from 61 g/kg for P. americanum cv. Tifleaf-I to 239 g/kg for sorghum cv. P-911 at site 1 and from 30 g/kg for sorghum cv. Savanna-5 to 167 g/kg for NK-367 at site 2. Predictive equations for the proportion of TNC retained after ensiling were developed using unfermented herbage characteristics as independent variables. These regression equations accounted for 70-91% of the variation. By wt, the most important fermentation products were lactate (42.9-114.1 g/kg), acetate (9.4-39.4 g/kg) and ethanol (1.4-50.0 g/kg). Only small quantities of substrate were fermented to propionate (0.0-1.3 g/kg), butyrate (0.3-1.6 g/kg) and acetaldehyde (0.4-1.3 g/kg). Palatability was positively correlated with acetate, propionate and total sugars in the silage. |
