In adult ewes, we tested whether ovarian function, including the response to short-term supplementation, was affected by the nutrition of their mothers during the pre-/postnatal period. A 2x2 factorial was used with nutrition in early life (low or high) and a 6- day supplement (with or without) as factors. All ewes received 3 prostaglandin injections 7 days apart, and the supplement (lupin grain) was fed for 6 days from 2 days after the second until the third prostaglandin injection. We measured reproductive and metabolic hormones, studied follicle dynamics (ultrasonography), and evaluated granulosa cell numbers, aromatase activity and oestradiol concentrations in follicular fluid in healthy follicles at Days 3 and 7 of supplementation. Ovulation rate was increased by 25% by exposure to high pre-/post-natal nutrition (1.5 versus 1.2; P < 0.05), in association with a small decrease in FSH concentrations (P = 0.06) and a small increase in insulin concentrations (P = 0.07). The number of healthy astral follicles was not affected. Acute supplementation increased the number of granulose cells (3.7 ??0.2 vs 3.0 ??0.2 million; P < 0.05) in the largest follicle, and the circulating concentrations of oestradiol (4.6 ??0.3 vs 3.9 ??0.3 pmol/L; P < 0.05) and glucose (3.4 ??0.03 vs 3.3 ??0.03 mmol/L; P < 0.01). Both early life nutrition and acute supplementation appear to affect ovulation rate through changes in glucose-insulin homeostasis that alter follicular responsiveness to FSH and therefore oestradiol-FSH balance.

El "guayabo del país" (Acca sellowiana) es una especie nativa que produce frutos comestibles, destacándose dentro de este grupo de frutales nativos por ser el de mejor conservación poscosecha y mejor tamaño de sus frutos, viabilizando así su comercialización como fruta fresca.
Los primeros trabajos a nivel de prospección, evaluación y selección de frutales nativos comenzaron en el año 2000, por parte de la Fagro - Udelar, INIA y MGAP, teniendo al guayabo del país como uno de los ejes centrales. |
