La cebolla ocupa un lugar importante dentro de los sistemas productivos en el sur del país. Durante la zafra 2013 se realizaron ensayos de evaluación de rendimiento de la línea de
cebolla de día largo en desarrollo, LB03 ?Santina? comparada frente a variedades (Pantanoso CRS, INIA Valenciana, Brava y Sintética 14 e híbridos comerciales disponibles (Pehuén y
Pandero), en INIA LB y en predios de productores de referencia de la zona Sur. Paralelamente en 2013 se realizaron ensayos de conservación prolongada a partir de los bulbos obtenidos de los ensayos en INIA LB y en predio de productor cosechados en 2012, para evaluar el potencial de conservación de ?Santina? comparándola con los materiales comerciales disponibles. Para la presente zafra se encuentra nuevamente en evaluación poscosecha para analizar su comportamiento. |

Abstract:
As daily methane production (DMP; g CH4/day) is strongly correlated with dry matter intake (DMI), the breeding of cattle that require less feed to achieve a desired rate of average daily gain (ADG) by selection for a low residual feed intake (RFI) can be expected to reduce DMP and also emission intensity (EI; g CH4/kg ADG). An xperiment was conducted to compare DMP and EI of Angus cattle genetically divergent for RFI and 400-day weight (400dWT). In a 6-week grazing study, 64 yearling-age cattle (30 steers, 34 heifers) were grazed on temperate pastures, with heifers and steers grazing separate paddocks. Liveweight (LW) was monitored weekly and DMP of individual cattle was measured by a GreenFeed emission monitoring unit in each paddock. Thirty-nine of the possible 64 animals had emission data recorded for 15 or more days, and only data for these animals were analysed. For these cattle, regression against their mid-parent estimated breeding value (EBV) for post-weaning RFI (RFI-EBV) showed that a lower RFI-EBV was associated with higher LW at the start of experiment. Predicted dry matter intake (pDMI), predicted DMP (pDMP) and measured DMP (mDMP) were all egatively correlated with RFI-EBV (P < 0.05), whereas ADG, EI, predicted CH4 yield (pMY; g CH4/kg DMI) were not correlated with RFI-EBV (P > 0.1). Daily CH4 production was positively correlated with animal LW and ADG (P < 0.05). The associations between ADG and its dependent traits EI and pMY and predicted feed conversion ratio (kg pDMI/kg ADG) were strongly negative (r = ?0.82, ?0.57 and ?0.85, P < 0.001) implying that faster daily growth by cattle was accompanied by lower EI, MY and feed conversion ratio. These results show that cattle genetically divergent for RFI do not necessarily differ in ADG, EI or pMY on pasture and that, if heavier, cattle with lower RFI-EBV can actually have higher DMP while grazing moderate quality pastures.
