Redesigning landscapes with multifunctional forage plants for an adequate zootechnical production and mitigation of environmental impacts

Abstract

In the 21st century, productivity gains from cattle raising could be aligned with more advanced environmental and social goals. Contrary to this logic, however, harmful effects have been associated with livestock systems, which leads to a clear need to minimize many of their negative impacts, such as deforestation, simplification of landscapes, loss of biodiversity and greenhouse gas emissions. The objective of this project will be to evaluate multifunctional ecosystems based on different forages for zootechnical viability and mitigation of environmental impacts with animal welfare. It results from the indication made by producers in another project where 3 alternative forages were selected (FAPESP 2020/16076-0). In an area of 42,000 m2, 15 experimental plots (2,800m2) will be defined, to be used in a randomized block design to evaluate the following treatments: 1) redesigned system containing brachiaria+blackberry (BA); 2) redesigned system containing brachiaria+gliricidia (BG); and 3) redesigned system containing brachiaria+titonia (BT). In the systems, 30 Nelore heifers will be allocated for six months, 2 per plot. Soil, plant and animal parameters that indicate which changes in production dynamics would be happening will be evaluated. In addition, parameters for modeling will be captured in the areas while collected data will be correlated with high resolution satellites.Our hypothesis is that multifunctional forage plants in redesigned productive landscapes manage to make zootechnically viable livestock activities with mitigation of environmental impacts.
