Animal performance and meat quality characteristics from feedlot-finished steers fed increasing levels of wet distillers grain
(Elsevier, 2023-10)One hundred forty-four steers were group-housed in 24 pens that were randomly assigned to one of four dietary treatments defined by the proportion of wet distiller grain plus solubles (WDGS; 0, 15, 30, or 45%) and fed for ... -
Transformation of tall-tussock grasslands and soil water dynamics in the Flooding Pampa
(Elsevier, 2023-10)Cow-calf production is the main practice within marginal agricultural lands of the world, like the Flooding Pampa of Argentina, where it promotes the transformation of native tall-tussock grasslands Paspalum quadrifarium ... -
Occurrence of pesticide residues in indoor dust of farmworker households across Europe and Argentina
(Elsevier, 2023-10)Pesticides are widely used as plant protection products (PPPs) in farming systems to preserve crops against pests, weeds, and fungal diseases. Indoor dust can act as a chemical repository revealing occurrence of pesticides ... -

(Oxford University Press, 2023-10)Congenital toxoplasmosis in humans and in other mammalian species, such as small ruminants, is a well-known cause of abortion and fetal malformations. The calcium-dependent protein kinase 1 (CDPK1) inhibitor BKI-1748 has ... -
Congenital hypovitaminosis A in dairy cattle
(British Veterinary Association, 2023-10-03)Hypovitaminosis A negatively impacts the health of ruminants feeding on low-fresh forage diets for long periods of time. Although this disease is characterised by different clinical presentations, its congenital form is ... -
Epilithic biofilms as a discriminating matrix for long-term and growing season pesticide contamination in the aquatic environment: Emphasis on glyphosate and metabolite AMPA
(Elsevier, 2023-11)The indiscriminate use of pesticides represents high ecological risk in aquatic systems. Recently, the inclusion of epilithic biofilms as a reactive matrix has shown potential in diagnosing the health of water resources. ... -
Exogenous progesterone during in vitro fertilization improves developmental competence of partially cumulus-denuded bovine oocytes
(Elsevier, 2023-11)The progesterone (P4) secreted by cumulus cells has gained attention for its role as a possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally accepted that fertilization rates of oocytes ... -
Efecto del epoxiconazol en mezclas sobre Puccinia striiformis f. sp. tritici en el cultivo de trigo = Effect of epoxiconazole in mixtures on Puccinia striiformisf. sp. triticiin wheat crop
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2023-11)Los fungicidas son la principal estrategia de manejo de roya estriada por Puccinia striiformis f. sp. tritici en trigo. El objetivo fue evaluar el aporte del epoxiconazol sobre el control de roya estriada. El ensayo se ... -
Analysis of factors controlling maize yield response to hairy vetch and to nitrogen fertilization after hairy vetch
(Elsevier, 2023-11)Context or problem: Several agricultural producers around the world are adopting hairy vetch (HV) (Vicia villosa Roth) inclusion in the crop sequence before maize (Zea mays L.). To date, it is not clear which factors control ... -
Transplacental infection by bovine alphaherpesvirus type 1 induces protein expression of COX-2, iNOS and inflammatory cytokines in fetal lungs and placentas
(Elsevier, 2023-11-05)Bovine alphaherpesvirus type 1 (BoAHV-1) is associated with respiratory and reproductive syndromes. Until present the immunologic mechanisms involved in BoAHV-1 abortion are partially known. We studied key elements of the ... -
Respiratory distress in Holstein cows fed corn silage: case report
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2023-11-28)An outbreak of respiratory distress was observed in Holstein cows immediately after consuming a new batch of corn-silage, presumably due to the presence of pneumotoxic gases. Signs were observed in 10% of the cows, and ... -
