Glanders is a highly contagious and often fatal zoonotic disease of equids caused by Burkholderia mallei, a pathogen of significant concern due to its potential for bioterrorism. In Brazil, glanders remains endemic, particularly among working equids in the Northeast region. Diagnostic confir...

Mixed legume–grass pastures may enhance nitrogen recycling via litter and excreta com‐ pared to unfertilized grass monocultures. This study evaluated litter biomass, litter dep‐ osition rate, and the chemical and isotopic composition of Urochloa decumbens litter in monoculture and mixed pasture&#...

This technical note describes a small ruminant respiration chamber system designed to accurately quantify the production of carbon dioxide (CO2) and methane (CH4). The system consists of 3 open-circuit respiration chambers, flow meters, gas analyzers, and an accessible environmental control syste...

Mahanarva spectabilis (Distant) is an important pasture pest in Brazil and represents an obstacle to forage production. Elucidating the chemical signals involved in the communication of this species is essential for finding new control alternatives. Therefore, the aim of this study was ...

Background: Snakebite envenomation is a worldwide public health issue, particularly relevant to low and middle-income countries. Bothrops spp. antivenom is needed for snakebite treatment, which requires the maintenance of healthy snakes in captivity. Hematology and clinical biochemistry are important ...

Natural and artificial selection leave footprints on the genome, known as selection signatures, that can indicate regions related to adaptive and economically important traits. The recurrent use of a limited number of sires and increased selection pressure may affect genetic diversity, poten...

Enzimas microbianas hidrolíticas, como amilase, celulase, xilanase, lipase e protease, são biocatalisadores que degradam biomoléculas complexas em produtos mais simples. Elas atuam de maneira sustentável sob condições ideais de pH e temperatura, são altamente estáveis e eficientes em transformações qu...

This study aimed to characterize residual feed intake (RFI) in 27 Girolando heifers, classified into three feed efficiency groups—high (HE), medium (ME), and low (LE)—across the calf, growing (150 and 450 days), and first-lactation phases. RFI was evaluated during both the growth and&#x...

Sensor technologies have gained traction in dairy farming, but remain underutilized during the calf pre-weaning phase. The objective of this study was to evaluate the correlation between sensor-derived variables (rumination time and activity index) and traditional performance metrics (average daily&#x...
