Summary: This article emphasizes the need to consider animal welfare when slaughtering decapod crustaceans and suggests using methods least likely to cause suffering. Current legislation protecting the welfare of decapod crustaceans is lacking, therefore the implementation of welfare guidelines to cover these economically important animals is necessary.

Summary: This paper focuses on alternative methods for initial broiler processing, including slaughter at the farm immediately after catching. The FSaT approach can improve bird welfare and well-being, as well as bring additional benefits such as improving yield efficiencies and reducing labor requirements.

Summary: The European aquaculture production of seabass and gilthead seabream is dominated by sea cage farms. Various methods such as brailing and pumping are used in the extraction process, with a focus on achieving unconsciousness in the fish prior to stunning. The most common stunning method is hypothermia, but alternatives like electrical stunning and anaesthetic with clove oil are discussed for their potential impact on fish welfare.

Summary: This study evaluated the impact of different slaughter methods on meat quality and various biochemical and hormonal parameters. The results showed that electrical stunning had some effect on meat quality, while there were no significant differences in blood parameters between the non-stunning and stunning groups. Proteomic analysis identified differentially abundant proteins between the two groups.

Summary: This study found that CO2 asphyxiation (T-4) had the least oxidative damage to large yellow croaker during cold storage, possibly because it had the least effect on mitochondrial structure, reactive oxygen species, and antioxidant enzyme activity. The T-4 samples showed minimal stress response, less damage to mitochondrial membrane potential and permeability, and maintained oxidative stability of the fish.

Summary: Appropriate stunning can make animals unconscious instantly, avoiding unnecessary pain and stress during slaughter. Scientific findings suggest that halal-compliant stunning technologies are reversible, do not kill animals prior to the halal cut, and do not obstruct blood loss.

Summary: The production of Italian heavy pigs differs from pig farming in other countries due to high body weight and age at slaughter. This review highlights the welfare issues of Italian heavy pigs in pre-slaughter phases and identifies knowledge gaps. Lack of understanding and standardized assessment protocols present challenges in improving animal welfare and ethical attributes in this renowned production.

Summary: This systematic review found a lack of consistent guidance on equine slaughter globally, along with a shortage of research on equine welfare during the slaughter process, particularly concerning donkeys and mules in low-income countries. The need to urgently develop an evidence base to improve guidance in this area was highlighted.

Summary: This systematic review identified a shortage of published research on equid welfare at slaughter, particularly focusing on donkeys and mules in low-income countries. Existing studies in equine slaughter show uncertainty and conflicting results, emphasizing the urgent need for further research to improve guidance in this area.

Summary: The handling and slaughtering of animals have a significant impact on meat quality. Halal slaughter, which involves cutting specific arteries and veins without stunning, allows for proper blood drainage and better preservation of high-quality meat. In contrast, most stunning methods hinder the bleeding process, leading to badly bled meat that is harder to preserve. Proper halal slaughter requires careful management to ensure good welfare and the production of high-quality meat.

Summary: Different stunning methods were tested on African sharptooth catfish, revealing that ice slurry immersion induced insensibility quickly, electrical stunning induced immediate but not irreversible insensibility, and manual percussive stunning could induce immediate and irreversible insensibility but with difficulties in administration. Combining methods, such as electrical or percussive stun followed by exsanguination and ice slurry immersion, could reliably induce and maintain insensibility until death.

Summary: This study conducted a scoping review to compare animal welfare indicators during stun and non-stun slaughter. The results showed that non-stun slaughter had a negative impact on animal welfare, with indicators including biochemical parameters, brain activity, and visual signs of consciousness. However, the study also highlighted limitations regarding inconsistent restraint method, neck cut position, and non-standardized measures of welfare at slaughter.

Summary: This study examined factors related to variation in pig responses to CO2 stunning in Australian commercial abattoirs. The research found differences in behavior among pigs in response to stunning, with some attempting to escape or crawl in the gondola, while others mounted other pigs. The study also revealed disparities in aversive responses to CO2 stunning between female and male pigs.

Summary: Information on slaughter procedures for farmed fish in Italy was collected through a questionnaire survey, and the gathered data revealed a discrepancy between the recommended practices for fish welfare and what is actually practiced in many production sites. Many specific recommendations for different species are still lacking.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.

Summary: Chicken manure has significant effects on the cultivation of Chlorella and rotifers. The optimal amount of chicken manure extract for continuous cultivation is 10 mLL-1. Chicken manure can promote the growth of Chlorella and improve the fatty acid composition, indirectly enhancing the growth condition and fatty acid content of rotifers.
