The role of microbiota during chicken manure and pig manure co-composting
Bioresource Technology, 2023Co-composting is an excellent and effective technology for treating livestock manure in which microorganisms play a crucial function. Therefore, this study aimed at investigating the changes of microbial interactions during co-composting. Six different addition ratios of chicken and pig manure were used in composting experiment. The results showed that

Co-Composting of Pig Manure with Leaves
Environmental Technology, 2001The increase in the market price of sawdust makes it a less attractive bulking agent for pig manure composting. Hence, it was the aim of this project to evaluate the feasibility of co-composting pig manure with leaves with special emphasis on its effects on compost maturity and quality. Two piles were prepared with one pile (Pile A) just constituted of

Degradation of doxycycline in aged pig manure
Acta Veterinaria Hungarica, 2011Two types of studies were carried out to characterise the degradation rate of doxycycline in manure. In the laboratory experiment, pig manure containing doxycycline was stored in biochemical oxygen demand (BOD) bottles in a thermoregulated room at a temperature of 20 ± 3.5 °C to maintain the humid and anaerobic incubation conditions, and the relevant ...

Composting of Cattle and Pig Manure
Journal of Veterinary Medicine, Series B, 1993SummaryStudies of solid manure treatment on 83 Swedish dairy farms showed that no composting process occurred in the majority of cases while high temperatures could be found in the manure in 27 of 34 piglet producing farms. It was found that at least 2.5 kg of straw per cow and day must be used to get a manure that can be composted without forced ...

Biochar-mediated sorption of antibiotics in pig manure
Journal of Hazardous Materials, 2019Using manure contaminated with antibiotics as fertilizer is a primary source of soil pollution with antibiotics and concomitantly with antibiotic resistance genes (ARG). Bioavailable antibiotics trigger further ARG amplification during manure storage. Consequently it is aimed to facilitate the immobilization of antibiotics in manure.

Regulation of fungal communities during pig manure composting
Bioresource Technology, 2023The role of protein shell (PS) amendment in altering the fungal community during pig manure (PM) composting was investigated. Six different dosages of PS based on the dry weight of PM (0 %, 2.5 %, 5 %, 7.5 %, 10 %, and 12 %; T1-T6, respectively) were mixed with wheat straw to make the initial feedstock and composted for 42 days. The results showed that

Nutrient Transformations During Composting of Pig Manure With Bentonite
Bioresource Technology, 2012This work aimed to evaluate the influence of different amounts of bentonite on nutrients transformation during pig manure composting process. The results showed that bentonite had no significant effects on compost temperature and pH changes. While, EC, moisture, OM, TN and NO(3)(-)-N were notably influenced by BT addition.
