Abstract:Sub-nutrition during pregnancy might affect the offspring´s reproductive performance through effects on the development and function of gonads. This study evaluated a maternal energy restriction in ewes from day 48?106 of gestation, on pre- and post-weaning female lambs` performance, onset of female lambs? breeding and ovulation rate during their first breeding season. Adult Polwarth ewes sired by Finnish rams bearing single or twin lambs were assigned to two dietary treatments from day 48 to day 106 of gestation: restricted (R; n = 60) at 60 % of their metabolizable energy (ME) requirements, or non-restricted (NR; n = 54) at 100 % of their ME requirements. After the restriction period, ewes grazed all together ad libitum until weaning. The ewe lambs were evaluated from birth to weaning, as well as during their first breeding season. Although NR ewes weighed 17.7 % more than R ewes (P < 0.05) at the end of the restriction period, the nutritional treatment of the dams had no effect on the weight of the ewe lambs at birth, weaning or final weight (P > 0.05). Fat depth, rib eye area, the percentage of ewe-lambs cycling and their ovulation rate during the first breeding season was not affected by the ewe´s dietary treatment. Ewes restricted at 60 % of their ME requirements in mid-gestation seemed to have the capacity to compensate any detrimental effects on growth and development as well as the reproductive potential of female lambs if adequate refeeding conditions are provided in late gestation, throughout lactation and post-weaning.

A pesar de la larga tradición en el mejoramiento y el estudio de la genética de distintos cultivos, el Instituto de Investigación Agropecuaria, INIA Uruguay, cuenta con un banco de germoplasma con condiciones para conservar semillas ortodoxas a largo plazo funcionando desde el año 1992 y con nuevas instalaciones desde el año 1998. Estas instalaciones incluyen cámara base de conservación de semillas a -20ºC, de 41m3, cámaras de conservación a mediano plazo funcionando a 5ºC y con control de humedad, e instalaciones de secado de semilla mediante sílica gel, así como respaldo de energía eléctrica. En la actualidad el banco de germoplasma conserva un total de aprox. 21600 muestras de semillas, de las cuales casi un 25% corresponden a accesiones de trigo. Estas accesiones incluyen variedades antiguas del instituto y de la región, material de mejoramiento, stocks genéticos y fuentes de resistencia a enfermedades, así como un importante número de introducciones procedentes del CIMMYT y del resto del mundo. Esta colección es curada en conjunto por mejoradores y fitopatólogos de la institución, realizándose anualmente trabajos de regeneración y mantenimiento de la misma. |
