Impact of Astaxanthin Concentration in Extender on Sperm Kinetics and Lipid Peroxidation After Cryopreservation in Beef Bulls

Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.
ABSTRACT Cellular damage caused by changes in temperature and osmolarity during cryopreservation primarily results in excessive generation of reactive oxygen species (ROS). These damages compromise the plasma membrane and reduce sperm fertility. Antioxidants help mitigate these effects.

Response of cereals to intercropping with non‐food crops in tropical and subtropical regions: A meta‐analysis

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping cereals with non‐food intercrops (NFICs) provides a means to enhance cereal productivity while providing additional benefits such as improved soil health or forage production. We conducted a meta‐analysis to investigate the effect of NFICs on cereal yields, cereal nitrogen uptake, and striga (Striga spp.) infestation, using 874 ...

Stylosanthes cv. Campo Grande response to Bradyrhizobium inoculation in an Amazon Cerrado Oxisol

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Species of the genus Stylosanthes show great potential for use in mixed pastures and as green manure due to their symbiotic potential in symbiosis with diazotrophic bacteria, particularly Bradyrhizobium. These herbaceous legumes can improve pasture quality and contribute to sustainability.

Genotype‐By‐Environment Interaction for Scrotal Circumference in Young Nellore Bulls Under Pasture and Feedlot Conditions and Its Correlation With Days to Calving

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Scrotal circumference (SC) is a key reproductive indicator in beef cattle and an important predictor of male puberty and correlated female fertility. In this study, we evaluated young Nellore bulls raised under combinations of pasture and feedlot environments and modeled SC using a “double” reaction norm model. Additive genetic variance for SC

Agronomic Traits, Physiological Parameters, Chemical Composition, and In Vitro Digestibility of Urochloa Brizantha Cv. Piatã, Megathyrsus Maximus Cv. Zuri and Megathyrsus Maximus Cv. Tamani in Silvopastoral Systems

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Urochloa species are widely used in silvopastoral systems (SPS), but production losses highlight the need for more productive forages. This study evaluated agronomic, physiological, chemical composition, and in vitro digestibility responses of Urochloa brizantha cv. Piatã and Megathyrsus maximus cvs.

Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...
