In a period of almost three decades, Uruguay built a forest industry based on fast-growing and short rotation eucalypts and pines
plantations, beside a policy planned native forests conservation. The government is currently boosting a transition to a bioeconomy that considers the potential of new products, processes, supply chains and markets conformation of both plantations and native forests. Secondary metabolites of native trees hold historically a great potential as non-wood forest products but have remained poorly investigated. This work presents advances in bioprospecting, identification, separation and chemical characterization of secondary metabolites of three forest trees, as raw materials for innovative non-wood forest products. The research initiated in 2013 through an agreement between the National Agricultural Research Institute and the Faculty of Chemistry of the Republic University of Uruguay. The activities focused on: (i) the bioprospecting of three species (Prosopis affinis, Prosopis nigra and Quillaja brasiliensis) and (ii) the identification and chemical characterization of selected secondary metabolites. Chemical analysis were realized using HPLC and mass spectrometry. Saponins, galactomannans and alkaloids were separated and characterized at laboratory scale. The next steps point to biomass production to enable an industrial pilot scale phase and economic studies on supply chains and markets conformation. |

We assessed the effects of high-intensity and low-frequency (HILF) vs. low-intensity and high-frequency (LIHF) grazing on herbage production and performance of beef cattle grazing sorghum pastures. The experimental design was a complete randomized block with two treatments and four replicates (paddocks), carried out in 2014/15. The management target of 50 and 30 cm for pre- and post-grazing, respectively, a LIHF grazing management strategy oriented to maximize beef cattle herbage intake per unit time, was compared with a HILF grazing management strategy of 80 and 20 cm for pre- and post-grazing, respectively, aiming to maximize herbage accumulation and harvest efficiency. Sixteen Brangus steers of 15-month-old and 265 ± 21 kg of live weight (LW) were randomly distributed to paddocks (experimental units). The LIHF resulted in shorter rest periods when compared with the HILF. The greater leaf lamina mass in LIHF allowed greater sward light interception at post-grazing, resulting in greater total herbage production than HILF (7581 and 4154 kg DM/ha, respectively). The average daily gain (ADG) of steers was greater for the LIHF than for the HILF treatment (0.950 and 0.702 kg/animal, respectively); however, even with a greater stocking rate in the HILF, there was no difference for LW gain per ha, with an average of 4 kg LW/ha/day. Our findings demonstrated that the LIHF strategy that is based on offering to the animals an optimal sward structure to favor the maximum herbage intake rate fosters greater herbage production, harvesting efficiency, and ADG without compromising LW gain per area of beef steers, despite the lower herbage harvested per stocking cycle.
