The survival of anaerobic fungi in cattle faeces
نویسندگان
چکیده
The survival of anaerobic fungi in cattle faeces was studied under a range of environmental conditions, in the laboratory, in cowpats, in slurry and in manure. Numbers of anaerobic fungi were enumerated as thallus-forming units with time after defacation and/or storage using the most probable numbers technique. Survival of anaerobic fungi was observed at a wide range of temperatures and moisture regimes but was relatively poor under certain conditions, notably in manure and in cowpats during the summer period. The results are discussed in relation to the survival of anaerobic fungi in their natural environment and the possible interactions with other micro-organisms present in ruminant faeces. ß 1999 Published by Elsevier Science B.V.

This study was conducted to compare digestibility of wheat straw (WS) by fungi and whole rumen microorganisms (WRM). Dry matter (DM), neutral and acid detergent fiber (NDF and ADF) digestibility of WS were compared with in vitro digestion (IVD), gas production (GP) and specific rumen anaerobic fungi culture (SRAFC). Dry matter, NDF and ADF digestibility of WS by WRM of buffalo (60.80, 49.93 and...

BACKGROUND Biological control of gastrointestinal nematodes of ruminants by use of nematophagous fungi would become part of any livestock parasite integral control system. Identifying autochthonous species that could then be selected for mass production is an important phase in the practical use of biological control. AIMS To search for nematophagous fungi with potential use as biological con...
متن کاملDistribution and estimation of anaerobic zoosporic fungi along the digestive tracts of sheep.
The status of anaerobic zoosporic (Chytridiomycota) fungi along the entire digestive tract of sheep was assessed both analytically and microscopically. Digest samples were taken from different segments of the digestive tracts of three newly killed sheep that previously had been used in experimental dietary studies. These digest samples were tested for the presence of rumen fungi by assessing th...
متن کاملComparison of growth characteristics of anaerobic fungi isolated from ruminant and non-ruminant herbivores during cultivation in a defined medium.
Anaerobic fungi were isolated from rumen fluid of a domestic sheep (Ovis aries; a ruminant) and from faeces of five non-ruminants: African elephant (Loxodonta africana), black rhinoceros (Diceros bicornis), Indian rhinoceros (Rhinoceros unicornis), Indian elephant (Elephas maximus) and mara (Dolichotis patagonum). The anaerobic fungus isolated from the sheep was a Neocallimastix species and the...
متن کاملComparison of growth rate and fatty acid profile of Nereis diversicolor fed with faeces and food of rainbow trout
Rainbow trout farms released always a large amount of organic matter into the environment, resulting in environmental contamination. If these waste can be used as a food source for the production of a secondary organism such as Nereis diversicolor, in addition to increasing production, it will reduce the volume of contamination originating from fish farms. In this regard, determining the nutrit...
