ABSTRACT - This study was conducted to evaluate the interaction between dose of estradiol cypionate (ECP) and ovarian status in beef cows on which different weaning/suckling regimens were imposed before fixed-time artificial insemination (FTAI). A total of 8070 estrous cycling and anestrous cows were subjected to three experiments, when calves were weaned early (Experiment 1), anti-suckling nose plates were applied for 9 or 10 days (Experiment 2), or there was continued suckling (Experiment 3). The cows were administered an estradiol/progesterone?based treatment regimen for FTAI and were treated with 0.5 or 1.0 mg of ECP im at the time of progesterone intravaginal device removal. Artificial insemination was performed from 46 to 56 h after the time of ECP treatment. Pregnancy per artificial insemination (P/AI) was affected by dose of ECP differentially in early-weaned and suckled cows. Whereas P/AI percentage was greater in early-weaned cows treated with 0.5 than 1.0 mg ECP (P < 0.05), P/AI percentage was greater for suckled cows treated with 1.0 than 0.5 mg ECP (P < 0.05). Although there were greater P/AI percentages in estrous cycling than anestrous cows (P < 0.05) when there was nose plate weaning and continuation of suckling, there was no difference between estrous cycling and anestrous cows (P = NS) when there was early weaning. Overall results indicate ECP administration affects fertility in a dose-dependent manner, suggesting an interaction between suckling and estrous cycling effects. As more critical the condition was (i.e., suckling anestrous cows), larger dose of estradiol was required. © 2021 MenosABSTRACT - This study was conducted to evaluate the interaction between dose of estradiol cypionate (ECP) and ovarian status in beef cows on which different weaning/suckling regimens were imposed before fixed-time artificial insemination (FTAI).

RESUMEN.- En este trabajo se buscó a través de la combinación de 2 estrategias reducir el contenido de alcohol en vinos de la variedad Tannat. La primera estrategia consistió en el screening dentro de clones uruguayos de Tannat Con este fin se muestrearon durante tres vendimias consecutivas 10 clones uruguayos de Tannat y se utilizó como referencia el clon francés 717 en viñedos. De los clones estudiados 4 presentaron durante la vendimia 2023 un contenido significativamente inferior de alcohol que el clon 717, manteniendo los componentes responsables de su calidad sensorial (aromas glicosidados, antocianos totales). Mientras que la segunda estrategia fue realizar un screening de levaduras no-Saccharomyces nativas aisladas de viñedos uruguayos para utilizar en conjunto con la cepa Saccharomyces cerevisiae Lalvin BM4x4 Lalleman (utilizada como referencia para vinificar vino Tannat). Se estudió el comportamiento de 4 géneros de levaduras (Candida zemplinina, Metschnikowia pulcherrima, Metschnikowia fructicola y Hanseniaspora uvarum), en microvinificaciones en símil vino. Estas estrategias fueron seleccionada por que además de permitir la reducción de alcohol en vinos Tannat en forma conjunta le aportan una identidad propia de nuestro país. .-.-.-.-.-.-.-.-.-.-.-.-.
