Extract of hop (Humulus lupulus), a plant used in beer production, could replace the antibiotics used to promote growth in chickens, according to a comparative study of 960 chickens carried out at the University of São Paulo (USP). Roasted breast fillets from chickens fed on feed mixed with hops for 42 days had the same color, consistency, and flavor as chickens fed on feed and antibiotics. Chemical analyses detected 95 volatile compounds, including those that relate to the quality of [...]

Implementing more sustainable soil management strategies, such as no-till with crop rotation and use of novel biological inputs based on organic waste or microorganisms, among other solutions, can help increase the efficiency of the mineral fertilizers critical to Brazilian agriculture, and hence reduce the volume of these fertilizers used. This is one of the main findings of studies supported by FAPESP and conducted by researchers affiliated with several universities and research institutions [...]

Understand the mechanisms that favor colonization In Brazil, a group of researchers supported by FAPESP created mutant forms of Salmonella to understand the mechanisms that favor colonization of the intestinal tract of chickens by these pathogenic bacteria and find better ways to combat the infection they cause. An article on the study is published in the journal Scientific Reports. In it, the researchers note that, contrary to expectations, the mutant strains caused more severe [...]
