ABSTRACT - This systematic review aimed to synthesize evidence on the effects of nitrogen (N) fertilization on forage production, animal performance, and greenhouse gas emissions in tropical pastures. The research question was developed based on the PICOS strategy. A total of 84,629 doc...
ABSTRACT - Studies on morphogenesis and tillering are crucial for pasture productivity and sustainability, as forage production depends on tiller performance and population density. This two-year study assessed the impact of four grazing frequencies on tillering dynamics and morphogenesis traits ...
ABSTRACT - The increasing climate variability in tropical regions demands management goals that allow for shorter rest periods without compromising pasture persistence. The objective of this study was to evaluate the effects of four pre-grazing light interception (LI) levels on the structura...
Understanding forage quality is essential for meeting animal demands and optimizing production. This study aimed to: (i) test the applicability of machine learning models with tabular data such as climate variables, light interception (LI), nitrogen dose (N dose), interval between grazing (G...
Animal production in the tropics is done mostly on native and cultivated pastures. Brazil is predominantly tropical and is the fifth largest country in the world with about 20% of its area covered by pastures (174 million ha). It has a natural aptitude for livestock produ...
Pastures of Brachiaria decumbens cv. Basilisk radically changed the scenario of central Brazil livestock production from the early 1970s and allowed the development of this vast region. Despite of the reasonable biomass yield and nutritional value, susceptibility to grassland spittlebugs limits&#...
ABSTRACT - This study assessed the economic feasibility of supplementation leveIs for beef catt1e grazing tropical pastures during the dry season. The central question was whether higher supplementation rates could improve system profitability and what leveI would provide the most advantageous&#x...
RESUMO - Objetivou-se determinar a composição, termogravimetria e calorimetria exploratória diferencial dos farelos de crambe e de soja destinados à alimentação de ruminantes. Foram avaliados o farelo de crambe, proveniente dos grãos cultivar FMS-Brilhante, e o farelo de soja, obtidos após e...
ABSTRACT - This large-scale study evaluated 25,512 Nellore bulls raised under tropical field conditions to elucidate multivariate determinants of breeding soundness and to derive a data-driven risk stratification framework based on BSE outcomes. Macro- and microscopic semen traits (e.g., progressive&#...
ABSTRACT - Background/Objectives: Antimicrobial resistance (AMR) is a global health threat, with raw milk serving as a potential reservoir for antimicrobial resistance genes (ARGs) and mobile genetic elements (MGEs). This study characterized the resistome and mobilome of raw milk from cows&#...
