Feb 1, 2021 · In those weeks, duck manure produced the highest methane production compared to other manure. An experimental study worked on a model biogas production unit which has 0.5 m3 fermentation tank ...
May 2, 2023 · Pre-treating animal manure to enhance hydrolysis can be dependent on the energy efficiency of the process as well as the complexity of the pre-treatment unit. For cattle manure, pretreatment can improve the biodegradability of the content of lignocellulose matter.
Four treatments diets were 45% (A), 30% (B), 15% (C) and 0% (D) levels of duck manure from total weight and it fed to catfish juvenile (weight 2,75±0,05 g) for 30 days controlled aquaria. The results of this studies found that the recommended diet was diet C and D formulations beacuse it can provide catfish juvenile growth response.
Oct 1, 2010 · The results showed that at (35±1)°C, biogas production potential of material (TS) was 0.273 m3/kg for sheep manure, 0.441 m3/kg for duck manure, and 0.210 m3/kg for rabbit manure.
Oct 1, 2008 · In comparison with other fermentation gases such as landfill or sewage gases, these manure gases are characterized by their high amount and diversity of selenium and tellurium species. Selenium-enriched duck food supplementation with tellurium impurities is suggested to explain the original presence of Se and Te in feather and/or excreta.

Jun 1, 2002 · In view of the factors affecting fermentation with the mixture of duck manure and straw, and the cumulative gas production from raw material mixed in different proportions, optimum temperature for
May 18, 2023 · A fermentation pile that is too small or too short can affect fermentation. The most suitable length, width, and height are about 1.5 * 2 * 3 meters. Duck manure organic fertilizer processing equipment 4. During the fermentation of aerated compost, it is important to remember to use aerobic fermentation.
Jul 18, 2020 · Results showed that BSFL fed with duck manure had significantly higher average individual weight of 0.0619±0.004 g, followed by mixture of duck manure and rice straw (0.0614±0.001 g), while
In view of the factors affecting fermentation with the mixture of duck manure and straw, and the cumulative gas production from raw material mixed in different proportions, optimum temperature for mixed anaerobic fermentation is about 30°C and the optimum proportion of raw materials is 2.8:1.
An experimental study worked on a model biogas production unit which has 0.5 m fermentation tank capacities of a breeding farm in the Urla district of Izmir/Turkey. The farm animal quantity is 70 cattle and 1400 chicken. Animal wastes (poultry manure and bovine animals manure) were anaerobically fermented in the tank. It is known in literature, the optimum fermentation occurs at 298-313 K
Apr 27, 2021 · The results showed that the microbial inoculum treatment could obviously promote the temperature rise of duck manure fermentation, and the high temperature stage lasted for a long time. The C/N value of microbial inoculum treatment was 2.6 lower than that of natural stacking control, and the degree of maturity was higher.
Analysis of chicken manure, duck manure and quail manure were carried out after going through the fermentation process. The elements analyzed are the elements pH, C-Organic, N-Total, C/N, P 2 O 5, and K 2 O (Table 2). Table 2. Results of chemical analysis of organic fertilizer (chicken, duck, and quail manure)
Apr 1, 2024 · All fermentation bottles were settled in an incubator for 16 days. About 20 mL mixture of sludge and chicken manure was extracted from the fermenter every two days to determine various indexes (determination items: pH, ORP, NH 4 +-N, PO 3--P, SCOD, protein, polysaccharide, VFAs). The reactor was adjusted to a stable state when all indexes were
