Integrated pest management based on the use of biopesticides is largely applied. Experimental bioassays are critical to assess biopesticide biosafety at the ecotoxicological level. In this study, we investigated the effects of the new ()-formulated-based biopesticides BLB1 and Lip, efficiently tested in field assays (IPM-4-CITRUS EC project no.

- The microbial community in the gut of dairy cattle plays a vital role in their energy levels, growth, and overall health from birth to lactation, impacting not only the farm's production efficiency but also food safety and environmental factors.
- The push to find alternatives to antibiotics in the U.S. has led to increased use of probiotics to enhance gut health, resulting in benefits like improved growth rates and milk yields in heifers; however, the effectiveness of these probiotics can vary greatly based on individual gut conditions.
- Advanced sequencing technologies are now helping to understand how probiotics change gut microbial diversity, which in turn influences cattle health and performance, highlighting that not all probiotics are equally effective and their success depends on various biological factors.
The purpose of this study was to determine the phylogenetic relationships among the primary betanodavirus strains circulating in Tunisian coastal waters. A survey was conducted to investigate nodavirus infections at 15 European sea bass Dicentrarchus labrax and gilthead sea bream Sparus aurata farming sites located along the northern and eastern coasts of Tunisia. The primary objective of the study was to create epidemiological awareness of these infections by determining phylogenetic relationships between the main betanodavirus strains circulating during the period 2012-2019, using RNA1 and/or RNA2 genome segments.

Social and market pressures are the driving forces behind the legislation and result in the change of poultry production management systems. As a result, the movement toward cage-free and aviary-based egg production systems has become standard practices.
View Article and Find Full Text PDFDue to consumer demand and changing welfare standards on health, ecology, equity, and safety concepts, poultry production has changed markedly over the past 20 y. One of the greatest changes to poultry production standards is now offering poultry limited access to the outdoors in alternative and organic poultry production operations. Although operations allowing access to the outdoors are still only a small portion of commercial poultry production, it may impact the gastrointestinal (GIT) health of the bird in different ways than birds raised under conventional management systems.
