Two medium scale composting experiments were carried out to study the effects of bulking agents, carbon to nitrogen ratio (C/N), aeration forms and additions on the swine manure composting under the moisture content of 68.8%. The changes of various indexes and the odor production and control were also studied.
The study found that the average bacterial numbers in all feces from six Giant Pandas in three age groups were 10 3cfu/g～10 7cfu/g,in which,the bacterial numbers of feces in young,adult and old Giant Pandas were 7 3×10 5cfu/g,7 8×10 5cfu/g and 2 0×10 6cfu/g,respectively.
The optimal rearing conditions a re temperature of 24～27℃, relative air moisture of 64%～70%, feces sifting rate of once in 2～4 days, density of larvae of 0.42～0.49 g/cm2 and fodder moistur e of 13.48%～17.48%.
4. Fecal cortisol fluctuated at a normal level under 5℃~30℃,however it sharply increased to a higher level, when environment temperature exceeded 30 ℃,2-3times as 5℃~29℃. it was shown that giant panda were suffered heat stress.
The results show that the earthwarms reproduced best in the fermented cattle dung plus 10 per cent of fermented chicken droppings and they did better in cattle dung fermented,air dried and dried in oven with 100℃ respectively.
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.
