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 ...
Biogas production from slaughterhouse waste: Effect of blood content and fat saponification
(Elsevier, 2021-08-12)
The effect of fat saponification and the inclusion or exclusion of blood in slaughterhouse mixtures were assessed in terms of anaerobic digestion performance. Mixtures of animal by-products (ABP) were ...
Non-destructive evaluation of carcass and ham traits and meat quality assessment applied to early and late immunocastrated Iberian pigs
(Elsevier, 2021-02-23)
Castration is a common practice in Iberian pigs due to their advanced age and high weight at slaughter. Immunocastration (IC) is an alternative to surgical castration that influences carcass and cut ...
Intramuscular vs. Intradermic Needle-Free Vaccination in Piglets: Relevance for Animal Welfare Based on an Aversion Learning Test and Vocalizations
(Frontiers Media, 2021-08-11)
The aim of the present study was to compare intramuscular injection with a needle and intradermic needle-free vaccinations against porcine reproductive and respiratory syndrome (PRRS) in piglets at 28 ...
The Optimal Valine to Lysine Ratio for Performance Parameters in Weaned Piglets
(MDPI, 2021-04-27)
The optimal digestible (d) Valine (Val) to d Lysine (Lys) ratio (dVal:dLys) in weaned
piglets was determined using two different regression models. A total of 200 piglets were allotted to
five feeding ...
Meat Consumers’ Opinion Regarding Unhealthy Pigs: Should They Be Treated with Antibiotics or Euthanized on Farm?
(MDPI, 2021-01-09)
The aim of this study was to investigate the opinions of meat consumers (n = 1780) on on-farm management of unhealthy pigs, whether support for treatment with antibiotics varies according with chance ...
Hydrophobic membranes for ammonia recovery from digestates in microbial electrolysis cells: Assessment of different configurations
(Elsevier, 2021-03-01)
The combination of hydrophobic membranes and microbial electrolysis cells (MEC) was assessed in two different configurations in order to recover ammonia from anaerobically digested pig slurry. ...

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, ...
Quality of Death in Fighting Bulls during Bullfights: Neurobiology and Physiological Responses
(MDPI, 2021-09-27)
During bullfights, bulls undergo physiometabolic responses such as glycolysis, anaerobic reactions, cellular oedema, splenic contraction, and hypovolemic shock. The objective of this review article is ...
