Abstract:
In wheat silage maintained for 21 days at 26°C and 9‐9 kPa water vapour pressure under a continuous flow of modified atmospheres (MAs) containing 20% v/v O2 and different concentrations of CO2 (from 20 % v/v to 80 % v/v) there was a significant increase in pH and in the colony‐forming units (CFU) of aerobic bacteria, yeasts and moulds. In addition, water‐soluble carbohydrates (WSC) and acetic and lactic acids decreased considerably. Similar results were obtained with a continuous flow of 90 %, 95 % and 99 % v/v CO2 (supplemented to 100 % v/v with O2) and with 100 % v/v pure O2 Only with silage kept in an atmosphere of 100 % v/v CO2 or of 100 % v/v N2 were no changes observed.
