Article Synopsis
- Fish meal is the primary protein source for farmed aquatic species due to its high nutritional value, but availability and cost issues have necessitated the exploration of alternative protein sources.
- A review analyzed various plant- and animal-derived proteins, finding that their inclusion levels can range significantly and can enhance fish health, growth, and fillet quality, though excessive amounts may hinder performance.
- The future of aquatic feed formulation is likely to involve a mixture of different protein sources to optimize nutrition, while more research is needed to better understand the impacts of these alternatives on various aquatic species.
Article Synopsis
- Domestic chicken farming is becoming popular in Italy and other places for self-consumption and this study examined toxic elements (As, Cd, Hg, Pb) in eggs from a local farm versus supermarket eggs.
- A total of 201 eggs were analyzed, revealing that supermarket eggs had higher lead contamination, while rural eggs had more arsenic in the albumen and shells, but both types had low levels of cadmium and mercury.
- While the toxic element levels weren't dangerous for health, the findings suggest a food safety concern, and there's a call to establish specific maximum residue limits (MRLs) for eggs to protect consumers.
Grains are major farm animals' diet ingredients, and one of the main concerns is when are mycotoxin (MyT) contaminated, compromising animals' health, performance, and product safety. Among the natural phytocompounds that are being used to prevent MyT damage, silymarin (SIL), an extract from the seed of the milk thistle (MT) is a suitable candidate. This review aims to examine the scientific evidence concerning the anti-MyT toxicity effects of MT/SIL in poultry and livestock.

- Milk thistle, known for its antioxidant and liver-protective properties, is used in both humans and animals to treat liver disease and improve overall health.
- Its use as a feed additive or ingredient in farm animals enhances performance, gut health, and liver function, while in pets it aids in managing liver diseases and supports treatments like chemotherapy.
- Overall, despite some inconsistencies in study reporting, milk thistle correlates with improved health and performance in various animal species.
Article Synopsis
- * The gastrointestinal tract is the first line of defense against these contaminants and plays a crucial role in their potential negative impact on health.
- * Various in vitro models have been used to study these mycotoxins' intestinal toxicity, and this review aims to provide a comprehensive overview of their effects on humans, along with information on their presence in food and feed and relevant regulatory issues.
Article Synopsis
- The growing global food demand prompts the exploration of invertebrates as alternative food sources, though Western consumers face barriers like fears and taboos.
- Two studies were conducted: the first identified key factors influencing food choices, while the second tested different labels for earthworm flour crackers to gauge consumer response.
- Findings revealed that health and sensory aspects heavily influence food decisions, with male participants responding more positively to nutritional claims on labels compared to female participants, suggesting that targeted communication strategies could help reduce aversion towards novel foods.
Article Synopsis
- The Sustainable Development Goals promote shared actions to achieve food security and reduce food waste.
- A pilot project on earthworm rearing demonstrated that 3750 kg of fruit and vegetable waste could be converted into 82 kg of earthworms and 1050 kg of compost in just three months.
- A risk analysis identified a microbiological hazard after freeze-drying, but heat treatment ensured the safety of earthworm meal as a nutritious protein source for both humans and animals.
Dairy farms have been widely acknowledged as a source of greenhouse gas (GHG) emissions. The need for a more environmentally friendly milk production system will likely be important going forward. Whereas methane (CH) enteric emissions can only be reduced to a limited extent, CH manure emissions can be reduced by implementing mitigation strategies, such as the use of an anaerobic digestion (AD).
