Abstract:

The anaerobic fungi in rumen fluid and faeces of two local goats in Nanjing area were isolated. The genera Neocallimastix, Piromyces, Orpinomyces and Anaeromyces were isolated from the rumen liquid of goat, and the genera Neocallimastix and Piromyces were isolated from the fresh faeces. The ability to degrade rice straw, wheat straw and cornstalk by these isolates was compared. The degradability of rice straw by all isolates was greater than 30%, while that of corn straw was less than 25%. When compared with the isolates from rumen liquid, the degradation by species isolated from faeces had a lower total gas production and degradability of dry matter when the three forages were used as substrates. There were some differences in degradability of forage by these organisms which could be explained by the differences in composition of the three substrates and by the characteristics of these isolates.
