Se han iniciado estudios respecto a la expansión de la agricultura en la zona centro-sur del Brasil. Los cambios en las matrices energéticas del planeta representan una oportunidad única para el país en la producción de etanol, a lo cual podría sumarse la producción de oleaginosas en sustitución de la caña de azúcar. Este estudio evaluó la expansión de la producción de etanol en la escala requerida para que Brasil pueda convertirse en el 'Arabia Saudita del etanol', lo que daría como resultado el desplazamiento de la frontera agrícola en MS y MT. En las áreas de rotación en los molinos de caña de azúcar ubicadas en las principales regiones de producción de etanol en el estado de Goiás y Mato Grosso do Sul se instalaron unidades de observación (UO) el 11 de octubre de 2009. Se evaluaron ocho cultivares de soya de centrales azucareras del país, y las que se adaptaron mejor al sistema de producción mejorado fueron BRS 232 y BRS 282. Este trabajo demuestra que la rotación en el centro-sur es técnicamente factible, de acuerdo con el cruce de la cosecha de caña de azúcar en la zonificación/soya. |

Abstract: This study aims to compare four different methods for selecting high responding sheep donors for in vivo embryo production. These methods include a pre-selection eCG test (eCG), antral follicle count (AFC), plasma anti-Müllerian hormone measurement (AMH) and genotyping for the presence of the FecGE mutation (a polymorphism in the GDF9 gene associated with increased ovulation rate). Santa Ines ewe lambs (n = 25) underwent superovulation (SOV) with 800 IU equine chorionic gonadotropin (eCG) and the corpus luteum (CL) count was recorded by laparoscopy after eight days. At the D0eCG, blood samples for AMH and genotyping analysis were collected. Twenty-one days after the end of the eCG test, the same animals underwent SOV with 200 mg of FSH, administered in six decreasing doses, and then naturally mated. Immediately before the beginning of the FSH protocol (D0FSH), and at the moment of the first FSH dose (D9FSH), the AFC was assessed. Plasma AMH was again determined at the D9FSH. After each screening process, animals were classified as having a high (HR), or low (LR), potential of response (using specific thresholds for each method). Then, the ewes' response to SOV and embryo yield for each screening method, classified as HR or LR, were compared. Animals classified as HR by AFC (HRAFC) and by AMH concentration (HRAMH) at the D9FSH, produced more viable embryos than those classified as LRAFC and LRAMH (HRAFC 6.2 ± 3.2 vs LRAFC 2.8 ± 3.0 and HRAMH 6.6 ± 3.6 vs LRAMH 3.0 ± 2.9). Pre-selection tests with eCG and different FecGE genotypes, either heterozygous (+/E) or wild type (+/+), were unable to discriminate HR or LR animals. A tendency (P = 0.06) to have lower plasma AMH was observed in heterozygous FecGE (+/E) ewes. In conclusion, both AFC and plasma AMH can be used to select donor ewes with a higher potential of response for in vivo embryo production.
