Roskopf Perez, Pablo Matías; Tieri, Maria Paz; Cuatrin, Alejandra; Ceron Cucchi, Maria Esperanza; Gere, Jose Ignacio; Salado, Eloy Eduardo (Scientific Research Publishing Inc., 2023-01)The objective of this study was to determine the effect of supplementation with a protected fat source on the productive response, metabolic environment and physiological indicators in Holstein cows under heat stress ... -
Performance of Lactobacillus paracasei 90 as an adjunct culture in soft cheese under cold chain interruption
Peralta, Guillermo H.; Bergamini, Carina Viviana; Costabel, Luciana Maria; Audero, Gabriela Maria; Ale, Elisa C.; Binetti, Ana; Wolf, I. Verónica; Cuatrin, Alejandra; Nieto, I.; Perotti, María Cristina; Hynes, Erica Rut (Elsevier, 2020-06)In this work, we simulated cold chain interruptions in soft cheeses of high-moisture to assess their impact on ripening, putting attention on the behaviour of an adjunct culture of Lactobacillus paracasei 90 (L90) when it ... -
Prevalencia de bacterias patógenas de mastitis bovina en leche de tanque de frío y evaluación de medios de cultivos para el recuento y la identificación de Staphylococcus aureus
Neder, Veronica Elizabeth; Signorini, Marcelo; Cuatrin, Alejandra; Gianre, Vilma Rita; Calvinho, Luis Fernando (2014)El objetivo del presente estudio fue estimar la prevalencia de bacterias patógenas de mastitis en muestras de leche de tanque en tambos ubicados en la cuenca lechera central Argentina. Además, se evaluó el desempeño de ... -
Productive response and reproductive performance of dairy cows subjected to different feeding systems
Salado, Eloy Eduardo; Maciel, Martin Guillermo; Bretschneider, Gustavo; Cuatrin, Alejandra; Gagliostro, Gerardo Antonio (Scientific Research Publishing, 2020-01)Fifty Holstein cows (2.6 ± 1.0 lactations) in early lactation (52.6 ± 16.4 days in milk) calved in autumn and producing 34.3 (±4.4) kg milk per cow∙day−1 were randomly assigned for 27 weeks to one of two treatments (feeding ... -
Productive Response of Dairy Cows Fed with Different Levels of Totally Mixed Ration and Pasture
Salado, Eloy Eduardo; Bretschneider, Gustavo; Cuatrin, Alejandra; Descalzo, Adriana Maria; Gagliostro, Gerardo Antonio (2018-07)Forty multiparous Holstein cows in early lactation (66 ± 19 days) were assigned to one of four treatments that consisted in different ratios of total mixed rations (TMR) and pasture at 100% TMR (T0), 75:25 (T1) 50:50 (T2) ... -
Sistemas de alimentación combinando pastura y ración totalmente mezclada : respuesta productiva y comportamiento reproductivo de vacas lecheras
Salado, Eloy Eduardo; Maciel, Nicolás; Bretschneider, Gustavo; Cuatrin, Alejandra; Castignani, Horacio (EEA Rafaela, 2014)La competencia de la agricultura por el uso de la tierra y su consecuente aumento de valor ha generado interrogantes sobre la continuidad de los sistemas ganaderos con alternativas de dedicarse a la actividad agrícola, ... -
Study of the effects of spray‐drying on the functionality of probiotic lactobacilli
Paez, Roxana Beatriz; Lavari, Luisina; Audero, Gabriela Maria; Cuatrin, Alejandra; Zaritzky, Noemi Elisabet; Reinheimer, Jorge Alberto; Vinderola, Celso Gabriel (2013-05)Three probiotic lactobacilli strains were spray‐dried in 20% (w/v) skim milk and submitted to a simulated gastrointestinal digestion. Fresh or spray‐dried cultures were administered to mice for 5 and 10 days, and Immunoglobulin ... -
Technological variables influencing the growth and stability of a silage inoculant based on spray‐dried lactic acid bacteria
Blajman, Jesica; Vinderola, Celso Gabriel; Cuatrin, Alejandra; Lingua, Mariana Soledad; Paez, Roxana Beatriz (Wiley, 2020-06)Aims: To investigate the influence of different culture media and fermentation conditions on growth performance and viability of three lactic acid bacteria (LAB) strains with potential as silage inoculants, and to optimize ... -
Use of cheese whey for biomass production and spray drying of probiotic lactobacilli
Lavari, Luisina; Paez, Roxana Beatriz; Cuatrin, Alejandra; Reinheimer, Jorge Alberto; Vinderola, Celso Gabriel (2014-08)The double use of cheese whey (culture medium and thermoprotectant for spray drying of lactobacilli) was explored in this study for adding value to this wastewater. In-house formulated broth (similar to MRS) and dairy media ... -

Yield components, light interception and radiation use efficiency of lucerne (Medicago sativa L.) in response to row spacing
Mattera, Juan; Romero, Luis Alberto; Cuatrin, Alejandra; Cornaglia, Patricia Susana; Grimoldi, Agustin Alberto (2013-02)Lucerne sowing is characterized by a rectangular spatial arrangement, i.e. greater distance between sowing rows than between plants in the row. Therefore, the reduction of row spacing generates more square spatial arrangements ...
