Theme 2-2: Forage Production and Utilization--Poster Sessions
Description
Two trials were conducted to evaluate the effect of white rot fungi treatment on feeding value of quinoa stalk. In trial 1, quinoa stalk was inoculated with Pleurotus osteratus (PO) or Pleurotus citrinopileatus (PC) at 25 °C for 90 days, and chemical composition and hardness of the stalk were measured. In trial 2, quinoa stalk was inoculated with PO, and incubated at 10 and 25 °C for 60, 90 and 120 days. After incubation, the chemical composition and hardness of the stalk were measured. In trial 1, acid detergent lignin (ADL) content in the stalk decreased in both treatments, and the ADL content was lower in PO than in PC. However, the hardness of the stalk after incubation was weaker in PC. In trials 2, ADL content and hardness of the quinoa stalk decreased under both incubation temperatures, but the decrease rates of the ADL content and the hardness were slower in the stalks incubated at 10 °C. After 120-day incubation, the ADL content was higher in the stalk incubated at 10 °C compared with the stalk incubated at 25 °C, but the hardness did not differ between the incubation temperatures. These results indicate the possibility of improving the feeding value of quinoa stalk by white rot fungi treatment under a cool climate condition such as Andean highlands.
