Gut eukaryotic communities in pigs: diversity, composition and host genetics contribution
(BMC, 2020-05-07)
Background
The pig gut microbiome harbors thousands of species of archaea, bacteria, viruses and eukaryotes such as protists and fungi. However, since the majority of published studies have been focused ...
Ammonium and Phosphate Recovery in a Three Chambered Microbial Electrolysis Cell: Towards Obtaining Struvite from Livestock Manure
(MDPI, 2021-10-27)
Ammonia and phosphate, which are present in large quantities in waste streams such as livestock manure, are key compounds in fertilization activities. Their recovery will help close natural cycles and ...
Struvite-based composites for slow-release fertilization: a case study in sand
(Nature Research, 2022-08-19)
Struvite (St) recovered from wastewaters is a sustainable option for phosphorus (P) recovery and fertilization, whose solubility is low in water and high in environments characterized by a low pH, such ...
Treatment of swine manure: case studies in European’s N-surplus areas
(Universidade de São Paulo, 2016-09)
In this study, eight different manure treatment plants were monitored. The plants were four on-farm and four centralized treatment plants, all of them at full-scale level. Assessment includes a total ...
Examining the perspectives of using manure from livestock farms as fertilizer to crop fields based on a realistic simulation
(Elsevier, 2021-10-13)
Intensive livestock production has a negative environmental impact by producing large amounts of animal dejections, which, if not properly managed, can contaminate nearby water bodies with nutrient ...
Influence of pH and Temperature on Struvite Purity and Recovery from Anaerobic Digestate
(MDPI, 2021-09-27)
The precipitation of struvite (MgNH4PO4.6H2O) from wastewater streams simultaneosuly recovers nitrogen (N) and phosphorus (P) for reuse as fertilisers. Struvite crystallisation is controlled by pH, ...
Effectiveness of precision feeding in reducing N excretion in dairy cattle
(Elsevier, 2023-07-01)
Two periods enrolling 56 (milk yield 36.2 ± 7.91 kg/d) and 58 (milk yield 32.4 ± 4.99 kg/d) grouped-fed dairy cows were performed to evaluate nutrient adjustment and N emissions of a precision feeding ...
Transfer of manure from livestock farms to crop fields as fertilizer using an ant inspired approach
(Copernicus Publications, 2020-08-03)
Intensive livestock production might have a negative environmental impact, by producing large amounts of animal excrements,
which, if not properly managed, can contaminate nearby water bodies with ...
Effect of decreasing dietary crude protein in fattening calves on the emission of ammonia and greenhouse gases from manure stored under aerobic and anaerobic conditions
(Elsevier, 2022-03-01)
Dietary strategies can potentially help to reduce nitrogen (N) emissions and decrease the environmental impact of beef production. This study aimed to evaluate the effects of dietary crude protein (CP) ...
Effect of Bacillus spp. direct-fed microbial on slurry characteristics and gaseous emissions in growing pigs fed with high fibre-based diets
(Elsevier, 2016-07-14)
A 26-day trial with 18 Pietrain × (Landrace × Duroc) pigs was conducted to investigate the effect of two dose levels of a specifically selected Bacillus spp. direct-fed microbial (DFM) product, on the ...
