Abstract: The manipulation of growth can be used as a strategy to reduce feeding costs. The objective of this study was to analyze, by deterministic and stochastic simulation, compensatory growth effects on the bioeconomic results of growing-finishing beef cattle systems. Four beef cattle systems were simulated with different feed restriction periods (no restriction, CONT; 90 days of restriction, COMP90; 120 days of restriction, COMP120; and 150 days of restriction, COMP150). Risk analysis was performed using the Monte Carlo method. Animals in feed restriction systems demonstrated partial compensation and required longer periods to achieve slaughter weight than CONT steers (16, 23 and 27 more days for COMP90, COMP120 and COMP150, respectively). The CONT system was the most productive (466 kg/ha/year), followed by COMP90 (443 kg/ha/year), COMP120 (432 kg/ha/year), and COMP150 (383 kg/ha/year). The most profitable system was the COMP90 system (US$ 161/ha) followed by the CONT (US$ 144/ha). The lower net margin was observed in the COMP120 (US$ 107/ha) and COMP150 (US$ 90/ha) systems. The risk analysis showed that COMP90 presented the highest financial stability. For all simulated systems, prices of finished steers, feeder calves, and corn were the variables with the greatest effects on net margin. The use of compensatory growth can be a tool to reduce feeding costs in beef cattle systems; however, the feed restriction must not be longer than three months. |

ABSTRACT.
Participatory approaches are needed to ensure learning processes and to incorporate lessons learned during the implementation of a project. This is particularly important
when the aim is to improve farm sustainability considering changes in knowledge and skills, natural resources management and networking. This paper describes the Participatory Impact Pathways Analysis (PIPA) implemented within the participatory action research project ?Coinnovating for the sustainable development of livestock family-farming systems in Rocha, Uruguay?, which involved stakeholders for planning, monitoring and evaluating of the project?s progress. Six workshops were implemented during 2012 - 2015 to enhance the project?s actions. Participatory methods were used to adapt PIPA to the Uruguayan culture. During 2013 an interinstitutional network was established, a shared vision of expected project results was defined, as well as impact pathways, goals and activities to achieve them. During the 2014- 2015 workshops, reflections and suggestions led in turn to new or modified activities. This process contributed to confidence and commitment building, improving the quality of the established relationships and strengthening networking to enhance the dissemination of the project findings. As a result of the learning process, and inspired in the project?s methodological and technological results, one stakeholder organization established a project for another region. The last workshop focused on a participatory evaluation of the whole project, demonstrating that a successful innovation process took place. This Uruguayan case showed that within the coinnovation framework, the PIPA approach nurtured the creation of a common space for social learning and innovation, providing a useful instrument for rural development.
