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...

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...

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...

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 provided a comprehensive overview of the behavior of alfalfa genotypes in response to environmental variations. We utilized established methods from literature and examined the unique aspects of each approach to collectively create a criterion for recommending cultivars. To this e...

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...

This study aimed to i) conduct a descriptive analysis of the genetic progress in milk production achieved by the Girolando breed genetic improvement program in Brazil and ii) assess the impact of these programs on the intensity of enteric methane (CH₄) emissions.

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 ...
