12 Tools for Climate-Smart Decision Making for the Stocker/Feedlot Sector

Abstract

Abstract There is an increased interest in the use of climate-smart practices and technologies to be more effective in climate change mitigation. These practices include grazing management, pasture management, animal and herd management, animal disease and health, animal breeding, and supplemental feeding during the stocker phase. In the feedlot sector, climate-smart practices range from supply chain challenges including climate smart adaptation by crop producers, cattle type, manure management, health management, and use of growth promoting technologies. There are certainly other technologies not mentioned and are not meant to be marginalized. During the stocker phase, grazing management is highly variable and dependent on climatic conditions and variability, plant species and plant health, water management, soil health, and cattle type. A correct balance among the different land managers, government agencies, and recommendations from university researchers and Extension personnel should optimize these practices. For instance, there is a focus on rotational grazing to increase the efficiency of grazing management. However, in the southwestern U.S. this practice may not be practical given the vast area and landscape used in production. In certain geographical areas, pasture management is becoming increasingly important as decreasing water sources (particularly aquafer levels) are apparent. Some data suggests that now is the time to change from cereal crop production to perennial forages while water is still available to establish the forages. This, in turn, may improve soil health and carbon sequestration. However, as with all mitigation strategies, this may decrease supply of cereal grains available to small feedlot producers, albeit a significant amount of cereals are transported to the cattle feeding sector. Animal breeding programs to improved production, heat tolerance, disease resistance, and improved reproduction is important. As with any production practice, supplementation programs may become necessary under certain situations. It is well known that cattle treated for respiratory disease have poorer performance and carcass characteristics than cattle not treated. Use of growth promoting technologies improve animal performance and decreases total methane produced. No doubt manure production from feeding operations produce methane. Dairy and swine operations can harvest the methane and with use of biogas collectors flare off the methane or produce energy for electric generators, however, this is not practical under feedlot situations; however, application of manure to land may improve soil organic matter. Building resilience in evaluating climate-smart practices will satisfy multiple objectives including impacting food security without many constraints to adoption.
