Para ello, ... -
Alimentación de corderos con una dieta deficiente en zinc: efecto sobre parámetros relacionados con la absorción y el metabolismo del cobre
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2022-06)El objetivo de este ensayo fue estudiar el efecto del consumo de una dieta deficiente en zinc (Zn) sobre los niveles plasmáticos, la concentración tisular y la retención de cobre (Cu) en ovinos. Diez corderos fueron asignados ... -
Alimentación saludable: una revisión de la literatura para una definición integral en el marco de los Circuitos Cortos de Comercialización
(Universidad Nacional de Quilmes (Argentina), 2024-04)Existe un amplio consenso sobre la crisis del modelo global alimentario basado en procesados y ultraprocesados planteando el problema de la insostenibilidad, tanto de las prácticas de producción como de consumo. En búsqueda ... -
Amaranthus hybridus (syn. quitensis) intoxication in cattle in Argentina: Case report
(Elsevier, 2023-12)Amaranthus spp. is a nephrotoxic plant with unknown toxic principle, affecting production animals worldwide, mainly in South America. The aim of this paper is to describe 5 spontaneous outbreaks of A. hybridus intoxication ... -
Amylose starch with no detectable branching developed through DNA-free CRISPR-Cas9 mediated mutagenesis of two starch branching enzymes in potato
(Nature Publishing Group, 2021-02-22)DNA-free genome editing was used to induce mutations in one or two branching enzyme genes (Sbe) in tetraploid potato to develop starch with an increased amylose ratio and elongated amylopectin chains. By using ribonucleoprotein ... -
An architectural analysis of the elongation of field-grown sunflower root systems. Elements for modelling the effects of temperature and intercepted radiation
(Society for Experimental Biology, 1996-03)The effects of photosynthetic photon flux density (PPFD) and soil temperature on root system elongation rate have been analysed by using an architectural framework. Root elongation rate was analysed by considering three ... -
