    • 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 ...
    • Effects of high fiber energy supplements on production performance, milk composition and milk fatty acid profile from dairy ewes fed fresh cut Lolium multiflorum 

      Miccoli, Florencia Estefania; Perez, Carolina Daiana; Vargas Bello Pérez, Einar; Danelon, José Luis; Cantet, Juan Manuel; Martínez, Rocío; Bargo, Fernando; Colombatto, Darío; Palladino, Rafael Antonio (2022-02-15)
      Supplementation of dairy ewes under grazing systems can improve milk production but different responses can be obtained when using starch or high degradable fiber as energy sources. The aim of this study was to evaluate ...
    • Efficiency and stability in subtropical beef cattle grazing systems in the northwest of Argentina 

      Nasca, Jose Andres; Feldkamp, C.R.; Arroquy, Jose Ignacio; Colombatto, Darío (2015-02)
      The objective of this work was to evaluate the efficiency and stability of cow–calf, fattening and whole cycle beef cattle agro-ecosystems from the subtropical region of Argentina. For this purpose, an agro-ecosystem model ...
    • Essential oils from Argentinean native species reduce in vitro methane production 

      García, F.; Brunetti, Maria Alejandra; Lucini, Enrique Iván; Scorcione Turcato, M.C.; Moreno, Maria Valeria; Frossasco, Georgina; Colombatto, Darío; Martinez, Maria Jose; Martinez Ferrer, Jorge (2018-04)
      The aim of this study was to evaluate the effect of Argentinean essential oils (EO) on methane production during in vitro fermentation compared to EO with proven effects as rumen fermentation modifiers. A complete randomized ...
    • Evaluación de un modelo de producción de pasturas mediante pruebas empíricas 

      Nasca, Jose Andres; Berone, German Dario; Arroquy, Jose Ignacio; Feldkamp, C.R.; Colombatto, Darío (Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)
      En el presente trabajo se utilizó un modelo de crecimiento de pasturas desarrollado por McCall y BishopHurley. El objetivo fue evaluar si el modelo es capaz de simular las variaciones en producción primaria neta aérea en ...
    • Impact of chestnut and quebracho tannins on rumen microbiota of bovines 

      Diaz Carrasco, Juan María; Cabral, Claudio; Redondo, Leandro Martín; Pin Viso, Natalia Daniela; Colombatto, Darío; Farber, Marisa Diana; Fernandez Miyakawa, Mariano Enrique (Hindawi, 2017)
      The use of phytogenic dietary additives is being evaluated as a means to improve animal productivity. The effect of tannins seems to be the influence not only directly on the digestive process through binding of dietary ...
    • Prediction of the Ym factor for livestock from on-farm accessible data 

      Jaurena, Gustavo; Cantet, Juan Manuel; Arroquy, Jose Ignacio; Palladino, Rafael Alejandro; Wawrzkiewicz, Marisa; Colombatto, Darío (2015-07)
      Methane emission factor (Ym) is directly involved to calculate the worldwide livestock methane inventories, hence it is important to refine the estimation of this parameter for different livestock production systems. The ...
