Description
The objective of this work was to assess the evolution of the nutritive quality of big bales composed of multispecifies pastures (Phalaris acuática, Festuca arundinacea, Lolium perenne and Medicago sativa). Ten big bales were analysed after 90 and 120 days for the following: dry matter (%DM); crude protein (CP, %DM); pH; neutral detergent fibre (NDF, %DM); digestibility in vitro of DM (IVDMD, %DM); ammonia nitrogen (NH3-N/%TN); soluble protein (SP, %NT) and non structural carbohydrates (WSC, %DM).The results were analyzed through variance of the means and significant differences (p<0.05) were found in percentages of DM (32.9% and 27.8%); CP (12.1% and 8.6%); pH (4.6 and 6.7); IVDMD (61.1% and 53.2%); N-NH3/TN (11.8% and 36.0%); SP (8.6% and 12.6%) and no differences were found in NDF (60.2% and 61.6%) and WSC (2.8% and 1.9%) (p>0.05).
