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. |

Abstract:
The objective of this study was determine whether the amount of protein provided to cows during late gestation would affect postnatal growth and lead to changes on glucose, insulin and insulin-like growth factor concentrations. At 134 d prepartum, 68 multiparous Angus cows were blocked by BW and expected calving date and
randomly assigned to low protein level (LP, 6% CP) or high protein level (HP, 12% CP) and were allotted in 12 pens per treatment. At calving, cows were managed together on improved pastures until weaning. Calves were weighed and body measurements were recorded at birth. Blood samples were taken at birth and each 30 d until weaning at 180 d of age. Body weight at birth on HP progeny tended to be great than LP progeny (P=0.06). At birth, calves from LP dams had greater head circumference (P ? 0.01), heart girth (P=0.01) and cannon bone circumference (P=0.02). However, head circumference /birth BW ratio (P=0.04), heart girth /birth BW ratio (P=0.01), body length /birth BW ratio (P=0.05) and height /birth BW ratio (P=0.01) was greater on LP calves. Body mass index was greater in HP calves (P=0.04). No differences were found on BW of calves at weaning, adjusted 205d BW and ADG during lactation (P ? 0.10). Glucose concentrations were greater on LP
calves than HP calves from birth to weaning (81.0 ± 1.5 vs. 76.4 ± 1.2 mg/dl; P ? 0.001) without any change in insulin concentrations during preweaning growth (LP=1.61 ± 0.04 ng/ml; HP=1.61 ± 0.04 ng/ml; P ? 0.10). Insulin-like growth factor concentrations was less on LP calves at birth (P ? 0.05) and similar to HP calves
during postnatal growth (P ? 0.10). These data demonstrate that low protein during late gestation in bovine dams may affect fetal growth with proportional increasing of head circumference and low body mass index. Level of protein compromised glucose regulation in early life and affected the IGF-I concentration of newborn calves. MenosAbstract:
