A meta-analytical evaluation of the effects of high-salt water intake on beef cattle
Lopez, Agustin; Arroquy, Jose Ignacio; Hernandez, Olegario; Nasca, Jose Andres; Juárez Sequeira, Ana Verónica; DiLorenzo, Nicolas; Distel, Roberto Alejandro (Oxford Academic Press, 2021-08)Adequate drinking water is essential to maintain acceptable production levels in beef cattle operations. In the context of global climate change, the water scarcity forecasted for the future is a growing concern and it ... -
Dried distiller´s grains plus solubles supplementation improves low-quality tropical grass utilization on beef steers = Suplementação de grãos de destilação secos com solúveis melhora a utilização de grama tropical de baixa qualidade para novilhos de corte
Hernandez, Olegario; Lopez, Agustin; García, Elisa Mariana; Nazareno, Mónica Azucena; Arroquy, Jose Ignacio (Centro de Ciências Rurais, Universidade Federal de Santa Maria, 2022)This study was designed to evaluate the effect of corn dried distiller´s grains (DDGS) supplementation on feed intake, total tract digestibility, and ruminal fermentation of beef steers fed low-quality Guinea grass ... -
Gene expression of growth factor BMP15, GDF9, FGF2 and their receptors in bovine follicular cells = Expresión génica del factor de crecimiento BMP15, GDF9, FGF2 y sus receptores en células foliculares bovinas
Reineri, Pablo Sebastian; Coria, María Sumampa; Barrionuevo, María Guadalupe; Hernandez, Olegario; Callejas, Santiago; Palma, Gustavo Adolfo (Universidad de Córdoba (Colombia), 2018-12)Introducción. El crecimiento y la maduración folicular implican una serie de transformaciones de diversos componentes del folículo, como el ovocito, las células de la granulosa y de la teca. Varios factores de crecimiento, ... -

Whole Cottonseed as an Alternative to Mitigate In Vitro Methane Emissions on Low-Quality Forage-Based Diets
Hernandez, Olegario; Juárez Sequeira, Ana Verónica; García, Elisa Mariana; Zarate García, Natalia; Uñates Pellene, Francisco Augusto; Fissolo, Hector Miguel; Coria, María Sumampa; Lopez, Agustin (MDPI, 2025-12)Enteric methane (CH4) emissions from ruminants are one of the major contributors to greenhouse gas emissions (GHG) from agriculture. We hypothesized that increasing levels of whole cottonseed (WCS) in diets decreases CH4 ... -
