(Facultad de Agronomía y Veterinaria, Universidad Nacional de Río Cuarto, 2021-12-22)Mycoplasma spp. infections are associated with different clinical syndromes in ruminants: mastitis, pneumonia, arthritis, otitis, among others. Nevertheless, case reports of clinical diseases associated with Mycoplasma-infections ... -
Meat quality traits in the Greater rhea (Rhea americana) as influenced by muscle, sex and age
(2018-02)Meat from the Greater rhea (Rhea americana) could compete with traditional red meats, diversifying the market of protein products of animal origin. The meat from 32 rheas was used to study quality aspects and this included ... -
Methane and nitrous oxide emissions from dung patches deposited by grazing cattle supplemented with maize grain
(Elsevier, 2021-07-13)Feeding management represents an opportunity to improve cattle performance in grazing-based production systems and to mitigate emissions of greenhouse gases (GHG) from livestock production. However, it is unclear how diet ... -
Methodological performance of selenium determination in ruminal fluid by hydride generation atomic absorption spectroscopy
(Ediciones INTA, 2021-04)Selenium (Se) is a trace element used by multiple enzymes. In ruminants, Se present in food is released to ruminal fluid allowing its absorption in the small intestine. Se release may be analysed by hydride generation ... -
Methods to determine nitrogen in sunflower grains
(Asociación Argentina de la Ciencia del Suelo, 2021-12)In sunflower, grain oil concentration (OG) determines oil industrial yield and protein concentration (PG) determines the protein of by-products as pellets and meals (PM). There are various methodologies to quantify total ... -
Metsulfuron-methyl and glyphosate transport in a mollisol soil in the Pampean region of Argentina
(Soil Science Society of Pakistan, 2021-12-04)The agricultural activity poses the potential risk of contaminating groundwater resources because of the leaching capacity of the agrochemicals used. Glyphosate and metsulfuron-methyl are two herbicides widely used in the ... -
Un método simple y práctico para la determinación de densidad aparente
(2014)La condición física del suelo es fundamental para definir su calidad/salud y es afectada por el uso. Por ello, es necesario el seguimiento de los cambios en la condición física de los suelos bajo producción, a través de ... -
Métodos agronómicos y ambientales de determinación de fósforo en argiudoles del sudeste bonaerense = Agronomic and environmental phosphorus determinations in argiudolls of southeast of Buenos Aires
(2015-03-25)Los análisis de suelo son herramientas útiles para evaluar la fertilidad edáfica y efectuar recomendaciones de fertilización (métodos agronómicos). Otros métodos, denominados ambientales, estiman el fósforo (P) que puede ... -
