In two fermntation tanks in the field, the fatality rate of the same virus on the 3th and 1st day reached 94.75% and 94.11% resqeectively, but in open-air manure vat, 96% of fatality rate just appeared on the 9th day and only 66.88% on the 24th day in the control group.
The proper con-ditions for anaerobic fermentation of cow manure have hen optimized: with about 10%of substrate concenttation, 10%-20%of the seeding matetial amount, pH value strictly controlled at the range of partlally deviatetl alkali (pH value at 7.0-7.4), the addition of human excreta amount of less than 15%,and the C :N ratio of fermenting material at 20-25:1as well.
In the second day after treatment with the dose at 10 mg/mL of the alkaloid, the RGR reduced by 39.8%, and the food intake and the feces weight were respectively 57.7% and 57.4% of the controls.
The lowest amount of food ingested and voided feces, the lowest nutritional index, slowest development, lightest pupae and most mortality were found in those pine caterpillar larvae fed with pine needles which were 50% damaged.
The germination experiment of three groups of seeds (seeds from feces, dry fruits and extracted seeds from dry fruits) was carried out.
sinensis, the seeds from feces still have a relatively higher germination ratio.
Differences in the olfactory response of the palm civet to feces was observed only if they belonged to different species.
Using thin-layer chromatography of fecal bile acids to study the leopard (Panthera pardus ciscaucasica) population
Thin-layer chromatography (TLC) of fecal bile acids has been used to confirm visual identification of scat samples found in Armenia in 2004-2005 and attributed to the leopard (Panthera pardus ciscaucasica).
In total, 642 human fecal samples from children under five years of age, imunocompromised patients, and high-risk persons and 480 randomly selected rectal specimens of cows and calves in Isfahan were examined.
In horse fecal samples, we detected more than 60 morphologically distinct phage types, the majority of which were present as a single phage particle.
They also keep and concentrate major food sources of benthos (live and dead phyto-and zooplankton and fecal pellets) over the benthic community locations.
