Evaluating antibiotic occurrence, degradation, and environmental risks in poultry litter within Argentina's agricultural hub
(Elsevier, 2024-04)This study explores the relationship between poultry farming's antibiotic administration practices and residual antibiotic levels in the litter before its application onto agricultural soils. Twenty-three antibiotics were ... -
Relationship of Salmonella isolation with different serum and inflammatory intestinal parameters in natural fowl typhoid outbreaks from laying hens
(Elsevier, 2023-10)Our study was undertaken to determine the best samples and selective-differential plating media to be used for Salmonella spp. isolation. We also compared hematological and serum biochemical values, Salmonella biovar ... -
Beef Cattle Grazing Native Grasslands May Follow Three Different Supplement Response Patterns
(MDPI, 2023-08-07)Previous studies on winter supplementation of growing cattle grazing stockpiled native Campos grasslands suggest that forage allowance (FA), herbage mass, and weather conditions before and during the supplementation period ... -
Field and genetic evidence support the photosynthetic performance index (PIABS) as an indicator of rice grain yield
(Elsevier, 2023-07)The rice breeding process for grain yield could be effectively enhanced by developing efficient tools that accelerate plant selection through the rapid determination of reliable predictors. In this study, we have described ... -
Impacto de la castración en terneros al inicio del engorde sobre el bienestar y la eficiencia animal = Impact of castration in calves at the beginning of fattening on welfare and animal efficiency
(Facultad de Ciencias Agrarias, Universidad Nacional de Lomas de Zamora, 2021-06)La castración es una práctica ampliamente utilizada en terneros. La edad del animal y el método de castración provocan dolor y estrés en diferente magnitud. El estudio de sus efectos sobre el bienestar y la producción son ... -
Chicken litter: A waste or a source of chemicals? Fast pyrolysis and hydrothermal conversion as alternatives in the valorisation of poultry waste
(Elsevier, 2023-01)Poultry production is one of the main and fastest developing branches of the agri-food industry in the world. Chicken litter (ChL) is the most abundant waste from this industry and requires alternative treatments to help ... -
Contribución del bienestar animal a la calidad de la carne vacuna
(Ediciones INTA, 2022-08)El bienestar de los animales es un concepto que debe abordarse en todas las etapas de la vida de los bovinos. Su preservación no solo está integrada por aspectos éticos, sino también por la posibilidad de mejorar los niveles ... -
What Factors Control the Crude Protein Content Variation of a Basaltic “Campos” Native Grassland of South America?
(MDPI, 2022-08)Native grasslands are the main source of food for livestock in the Campos region of South America. These forage resources are heterogeneous in species composition, grazing management, and soil fertility within a context ... -
