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.

The Uruguayan rice sector has been one of the most successful and most integrated agricultural industries in the country. Rice yields in Uruguay have increased at one of the highest annual rates worldwide (145kg-1 ha-1 yr-1 from 2000 to 2017). However, this trend has shown a marked slowdown in recent years, which may be indicating that average rice yields approach the biophysical yield ceiling (Figure 1). Indeed average farm yields often begin to plateau when they reach 75 to 85% of the yield potential (CASSMAN et al., 2003; LOBELL et al., 2009). Determination of rice yield potential in Uruguay, is essential to identify opportunities for future yield gains. Also unknown is if the high increase in rice yield in Uruguay was partially determined or not by climate change. Due to current high inputs costs and low rice prices, keeping rice yields trend is critical for the viability and sustainability of the crop in Uruguay. The aims of this work were: firstly, to estimate rice yield potential (Yp) and current exploitable yield gaps (Yg) at regional and local-farm levels in Uruguay, secondly, to analyze current rice yield trends in Uruguay and to determine to which degree the incipient yield plateau can be attributed to a biophysical limit and thirdly to compare results with other rice producing countries included in the Global Yield Gap Atlas for which rice yield potential and yield gap estimates are available. |
