The antral follicular count (AFC) in cows has been linked to oocyte quality. This study aimed to evaluate oocyte quality in cows from different genetic groups with high or low AFC and to determine whether oocyte quality correlates with antioxidant status
The β-glucan has anti-inflamatory and anti-oxidant effects and improves immunity in transition cows. It was evaluated the effects of β-glucan supplementation in transition period on uterine involution and cytological endometritis occurence in Holstein cows.
A Avaliação do Ciclo de Vida (ACV) é uma ferramenta essencial para mapear impactos ambientais e apoiar o desenvolvimento de tecnologias mitigadoras. Estudos sobre a produção de carne bovina nos trópicos indicam que fatores como dieta do rebanho, genética e fertilidade influenciam as...
Estradiol esters can be used in timed artificial insemination (TAI) and embryo transfer (TET) protocols. Most studies on exogenous estradiol pharmacokinetics, however, used a standard dose, regardless of body weight and did not take into account the potential interference of endogenous estra...
In vitro ocular irritation testing requires the use of freshly excised bovine corneas, which limits broader adoption in laboratories with restricted access to slaughterhouse material. This study investigated a practical and accessible lowtemperature preservation strategy focused on maintaining structural&#...
The aim of this study was to characterize organic dairy systems in Brazil. It was hypothesized that the production level of the herd influences the productivity and marketing aspects of organic milk production systems. A descriptive analysis was carried out in which the variables&#...
Research utilizing Life Cycle Assessment (LCA) in milk and beef production in tropical environments demonstrates that factors such as herd diet, genetic composition, and reproductive efficiency significantly influence estimates of CO2 equivalent (CO₂eq) emissions. The objective of this study was ...
O gênero Urochloa engloba uma diversidade de forrageiras cultivadas em regiões tropicais e subtropicais.Com a crescente demanda global por produtos agropecuários,programas de melhoramento buscam aprimorar a qualidade e produtividade das pastagens por meio de cruzamentos intra e interespecíficos.No clado&#x...
O híbrido interploide 7F/153, derivado do cruzamento entre U. ruziziensis (2n = 4x = 36, tetraploide artificial) e U. brizantha (2n = 5x = 45), apresenta 2n=40 cromossomos e constitui material relevante para estudos citogenéticos e de melhoramento. Entretanto, análises prévias sugerem&#...
O leite é considerado um dos alimentos mais consumidos no Brasil; entretanto, é notável o surgimento de bebidas vegetais que visam sua substituição. Estudos indicam que a escolha de tais bebidas é influenciada por diversos fatores, como novas tendências de consumo e restrições alim...
