ABSTRACT: While low-cost technology can be applied within beef cattle systems to improve economic output and decrease economic risk, methodologies to increase adoption by farmers deserve attention. Here we report 4 case studies where low-cost, high-impact technology was applied on commercial farms in an endeavor to demonstrate increased physical output in what we describe as 'Producer Demonstration Sites'. Forage allowance (FA) affects forage growth, forage intake by animals and energy partitioning to maintenance or production. We decided to demonstrate the benefits to production from controlling forage allowance at specific recommended levels. While we focused on FA, other management tools, e.g. suckling restriction and energy supplementation of cows prior to breeding, were tested in different contexts and time periods to improve the critical responses mentioned. While increases in production from 3 of the farms were demonstrated, only 2 of the farmers showed interest in implementing the strategies on their farms subsequently. We conclude that control of forage allowance improved energy intake and animal productivity. For this approach to be successful and increase adoption, it is important to involve the farmers in discussions regarding the proposed changes from the outset as well as the monitoring of progress during the demonstration. |

Abstract: Commercial forestry in Uruguay is mainly based on non-native Eucalyptus and Pinus plantations. Eucalyptus is the most planted genera and covers approximately 730,000 ha. Currently, forest products represent one of the top three exports of the country. Over the last two decades, the number of reported pests that threatens commercial plantations has increased regularly, not only due to accidental introductions of exotic pests but also because of host shift of native pests and diseases from the native forest to the exotic forestry species. Some of the recently introduced pathogens have dramatically impacted on eucalypt plantations. For instance, Teratosphaeria nubilosa, reported in 2007, has forced the replacement of Eucalyptus globulus with more resistant species. More recently, Teratosphaeria pseudoeucalypti, another introduced pathogen reported in 2014, has dispersed very fast all over the country affecting many eucalypt species. On the other hand, Austropuccinia psidii, the causal agent of myrtle rust, originally described from native Myrtaceae, has shifted to eucalypts and affects young plantations. Foliar bacterial blight, bacterial wilt and dieback, and root diseases also affect plantations with sporadic incidence through the years. In most cases, the use of resistant species and resistant planting stock is the most effective approach to mitigate the impact of diseases on commercial plantations. The increasing international commercial trade, that results in more opportunities for pathogens to move among distant areas and continents, requires reinforced national surveillance and quarantine regulations.
