Efecto de la suplementación con ciclodextrinas cargadas con colesterol al semen sexado bovino post-descongelación para su uso en producción in vitro de embriones
(UCOPress. Cordoba University Press, 2018)Los espermatozoides bovinos presentan una bajo relación de colesterol/fosfolípidos en la membrana plasmática. Esta característica es importante ya que el colesterol juega un papel fundamental en el mantenimiento de la ... -
Efecto del uso de leche concentrada por ultrafiltración sobre el rendimiento y la maduración de quesos semiduros
(Asociación Argentina de Tecnólogos Alimentarios (AATA), 2023-10)El incremento en la cantidad de proteínas de la leche destinada a la elaboración de quesos mediante el agregado de leche ultrafiltrada (LUF), puede resultar una estrategia interesante para aumentar el rendimiento quesero. ... -
Efectos del volumen de celda, la edad de transplante y la poda sobre la productividad del cultivo de melón (Cucumis melo L.)
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2010-11)El experimento uno consistió en tres celdas: 20, 40 y 120 cm3 y tres edades de transplante 48, 34 y 20 días desde la siembra. El experimento dos utilizó dos celdas: 20 y 120 cm3 y dos edades de transplante 62 y 38 días, ... -
Effect of deforestation and introduction of exotic grasses as livestock forage on the population dynamics of the cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) in northern Argentina
(2013-12)The effect of deforestation and the introduction of exotic grasses on the population dynamics of Rhipicephalus (Boophilus) microplus in northern Argentina was analysed. Biological parameters that were measured included ... -
Effect of different mini‐volume colloid centrifugation configurations on flow cytometrically sorted sperm recovery efficiency and quality using a computer‐assisted semen analyzer
(Wiley, 2018-02)Straws of sex‐sorted sperm are usually packaged at a low concentration (e.g., ~2.1 × 106 sperm/ml) and cost significantly more than unsorted conventional semen from the same sire. In order to maximize the efficiency of ... -
Effect of ensiling a total mixed ration on feed quality for cattle in smallholder dairy farms = Efecto de ensilar una ración totalmente mezclada sobre la calidad nutritional para el ganado en pequeñas explotaciones lecheras
