Reactive oxygen species (ROS) and oxidative stress (OS), the imbalance between the production of free radicals and the cellular antioxidant defenses, are discussed in relation to their role in bovine sperm physiology. Oxidative stress has been associated to male infertility and low fertility rates in Assisted Reproductive Techniques (ART). Antioxidant supplementation is an interesting approach to overcome OS-related infertility and assisted reproduction drawbacks. Several studies have been conducted to identify the potential sources of ROS in a typical ART setting and the impact of antioxidant supplementation on semen quality and pregnancy outcome. Procedures such as freezing and thawing, centrifugation and incubation are thought to produce significant amounts of ROS with a negative impact on sperm quality parameters and reproductive competence. Given the important role of ROS in sperm function, the addition of antioxidants in sperm media to prevent OS and to improve the reproductive outcome requires attention. Currently, there is limited evidence to support the ameliorative effect of antioxidant supplementation on fertilization and embryo development in farm animals. This review summarizes the different types and concentrations of antioxidants used in sperm preparation media of bovine species and their effectiveness in neutralizing excessive ROS production while preserving physiological sperm function.

Introduction: Free radical-mediated oxidative renal tubular injury secondary to hyperoxaluria is a proposed mechanism in the formation of calcium oxalate stones. Vitamin E, an important physiologic antioxidant, has been shown in rat models to prevent calcium oxalate crystal deposition. Our objective was to determine if low dietary vitamin E intake was associated with a higher incidence of stones.

Weaning stress-induced diarrhea is a serious issue in pig production. This study aimed to evaluate the potential of glucose oxidase (GOD) as an antibiotic substitute to alleviate diarrhea and improve gut health in weaned piglets. According to a randomized complete block design, 250 piglets weaned around 21 d of age were allocated into 5 groups (5 replicates/group), which received a basal diet without or with supplemental 200 mg/kg antibiotic, 500, 1000 and 2000 U/kg GOD, respectively.

Article Synopsis
- The yeast Pichia caribbica from the Meyerozyma guilliermondii species complex shows diverse abilities that help it adapt and survive in various environments.
- The study explored how phytic acid (PA) can improve P. caribbica's effectiveness in protecting table grapes from decay and preserving their quality, with findings indicating that PA enhances yeast growth and biofilm formation.
- Treatment with PA not only increased antioxidant enzyme activity in P. caribbica but also led to better control of grape decay during storage, demonstrating potential for sustainable postharvest solutions that consumers found appealing based on improved grape quality.
