Effect of Post-Weaning Concentrate Feeding Prior to Forage Finishing on Intramuscular Fat Deposition
(MDPI, 2024-02)The objectives of this study were to examine the effects of feeding high-concentrate diets post-weaning (PW) prior to forage finishing on (1) changes in ultrasound intramuscular fat deposition and lipogenic/lipolytic gene ... -
Natural grassland conversion to agriculture or pine plantations: Effects on soil methane uptake
(Wiley, 2024-01-30)Upland soils are the only known biological sink for methane (CH4) by methanotrophic bacteria consumption. This process is mainly limited by the diffusion processes related to the soil's physical characteristics, which can ... -
Bovine campylobacteriosis in heifer: pathogenesis study and insights in the conventional and molecular diagnosis in an experimental bovine model and field cases
(Springer Nature, 2024-02)Campylobacter fetus spp. is a bacterium associated to reproductive losses in cattle worldwide. It is a venereal infectious disease known as bovine campilobacteriosis, with high impact mainly in countries with extensive ... -
Sorghum biomass yield and allocation as affected by the combination of photoperiod sensitivity, sweet-stalk and brown midrib traits
(Elsevier, 2024-01)Context or problem: Traits like photoperiod sensitivity, sweet-stalk and brown midrib (bmr) have been introgressed to increase the biomass yield and quality of sorghum (Sorghum bicolor (L.) Moench) towards bioenergy yield ... -
A time-window within the grain filling period accounted for early leaf senescence in maize under sink limitation
(Elsevier, 2024-01)In annual crops such as maize, assimilates demand exerted by grains converges with increasing leaf senescence. As sink demand changes as grains growth, leaf senescence could also be affected during the grain filling period. ... -
Assessing the effect of split and additional late N fertilisation on N economy of maize
(Elsevier, 2024-03)Context: In the temperate-humid region of Argentina, nitrogen (N) fertilisers in maize (Zea mays L.) are mainly applied around sowing, whereas N-splitting is rare and occurs during early vegetative stages. Splitting and ... -
Pesticide pollution in argentine drinking water: A call to ensure safe access
(Elsevier, 2024-01)The application of pesticides in Argentina has been on the rise since 2000. However, the monitoring of pesticides in drinking water lacks regular updates. This research study analysed 53 pesticides and degradation products ... -
Effect of Campylobacter fetus on in vitro fertilization and embryonic development of preimplantation bovine embryos
(Elsevier, 2024-01)Campylobacter fetus is an important veterinary pathogen that causes campylobacteriosis. This disease causes decreased productivity of cattle by inducing reproductive losses. Although several virulence factors have been ... -
Fertilización combinada con N-P-S-Zn en avena, cebada y trigo
(Asociación Argentina de la Ciencia del Suelo, 2023-12)En Argentina, nitrógeno (N) y fósforo (P) y recientemente azufre (S) y cinc (Zn) son nutrientes reconocidos como limitantes de la producción de los cereales de invierno. Las decisiones de manejo de la fertilización en avena ... -
Otras causas de pérdidas reproductivas en bovinos. Pensando más allá de las etiologías infecciosas
(Ediciones Taurus, 2024-02)Teniendo en cuenta un mercado internacional cada vez más demandante de sistemas de producción de carne y leche bovina sustentables, es imprescindible mejorar los parámetros reproductivos de la producción pecuaria local. ... -
Infectious sporadic bovine abortions: retrospective analysis
(Springer Nature, 2024-03-01)Infectious sporadic abortions in cattle are mainly caused by opportunistic bacteria and fungi usually present in environmental or gastrointestinal and reproductive microbiota of healthy animals. A retrospective analysis ... -
Effect of on-farm poultry litter composting processes on physicochemical, biological, and toxicological parameters and reduction of antibiotics and antibiotic-resistant Escherichia coli
(Elsevier, 2024-02)Poultry litter is a valuable source of nutrients for crop production, but its use in agriculture can lead to environmental and public health concerns due to the presence of pollutants, antibiotic-resistant bacteria (ARB) ... -
MARCHI: A serious game for participatory governance of ecosystem services in multiple-use protected areas
(Elsevier, 2023-07-28)The management of multiple-use reserves is challenging due to trade-offs between the conservation of natural capital, the provision of different ecosystem services (ES) and the capture of its benefits, as well as a poor ... -
Change of soil carbon storage in monoculture tree plantations across wide environmental gradients: Argentina as a case study
(Elsevier, 2024-01)Forest plantations (through afforestation or reforestation) have been proposed as a valuable option to mitigate carbon (C) emissions. However, high spatiotemporal variation has been observed in soil organic carbon (SOC) ... -
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 ... -
