(Springer, 2020-05-16)Detection of bovine viral diarrhea virus (BVDV) in aborted fetus samples is often difficult due to tissue autolysis and inappropriate sampling. Studies assessing different methods for BVDV identification in fetal specimens ... -
Improving concentration of healthy fatty acids in milk, cheese and yogurt by adding a blend of soybean and fish oils to the ration of confined dairy cows
(2020-01-18)Compared to pasture based sistems, milk produced in confined dairy systems is characterized by a high saturated fat (SF) content with a lower concentration of healthy fatty acids (FA) such as vaccenic (VA, trans-11C18:1), ... -
Forestación en pastizales: el rol de las especies y el manejo forestal sobre el proceso de salinización secundaria de suelos
(Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)La introducción de forestaciones con especies de rápido crecimiento donde la vegetación original es la de pastizal puede traer aparejado cambios en los flujos de agua, causando la movilización de las sales disueltas en el ... -
Calidad nutritiva de láminas de dos cultivares de festuca alta (Festuca arundinacea Schreb)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)Se evaluó la calidad nutritiva de dos cultivares de festuca alta (Festuca arundinacea Schreb) durante un rebrote estival (temperatura media: 21±2.8 °C), en relación a la morfogénesis de dos cultivares (Tradicional: El ... -
Nitrato en pecíolo e índice verde en estratos del canopeo del cultivo de papa
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)La concentración de nitrato en los pecíolos (NBS) y el Índice Verde (IV) medidos en las hojas inferiores del canopeo de papa podrían usarse como alternativa de los métodos tradicionales de evaluación del estado nutricional ... -
Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ... -
Plant interactions and ergovaline concentration in mixture of Lotus tenuis and Schedonorus arundinaceus infected with the fungus Epichloë coenophiala
(Asociación Argentina de Ecología, 2020-01-08)Schedonorus arundinaceus (tall fescue) population can be infected by the endophyte fungus Epichloë coenophiala, responsible of livestock intoxication due to fungal alkaloids (i.e., ergovaline). The effects of ergovaline in ... -
