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 ... -
Chemical composition and in vitro ruminal degradation of hay and silage from tropical grasses
Arroquy, Jose Ignacio; Cornacchione, Monica; Colombatto, Darío; Kunst, Carlos Roberto (2014)This study was conducted to evaluate the effects of preservation type on chemical composition and in vitro ruminal degradation of warm-season grasses (WSG). Treatments consisted of two factors (6 2): the first factor was ... -
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 ... -
Early exposure to and subsequent beef cattle performance with saline water
Lopez, Agustin; Arroquy, Jose Ignacio; Distel, Roberto Alejandro (2016-03)Two experiments were conducted to evaluate the impact of early life exposure to high salt water on later cattle performance with saline water. In Exp. 1, 24 cow/calf pairs were randomly assigned to one of two treatments: ... -
Exploring the biological activity of condensed tannins and nutritional value of tree and shrub leaves from native species of the Argentinean Dry Chaco
García, Elisa Mariana; Cherry, Nicole; Lambert, Barry D.; Muir, James P.; Nazareno, Mónica Azucena; Arroquy, Jose Ignacio (2017)BACKGROUND: Tropical tree or shrub leaves are an important source of nutrients for ruminants and a potential source of biologically active compounds that may affect ruminalmetabolism of nutrients. Therefore, eightwoody ... -
High-sulfate water consumption determines intake and metabolic responses to protein supplementation in lambs consuming low-quality forage
Lopez, Agustin; Arroquy, Jose Ignacio; Juárez Sequeira, Ana Verónica; DiLorenzo, Nicolas; Barrionuevo, M.C.; Distel, Roberto Alejandro (2017-05)Twenty Hampshire lambs (31 ± 4 kg BW) in individual metabolism cages were used in a 10-treatment by 2-period (n = 4) trial to evaluate the interaction between protein supplementation and sulfate water on intake and metabolic ... -
