Purdue University researchers released on May 4 a comprehensive literature review that offers an integrated approach to making livestock production more sustainable. The study, led by Hinayah Rojas de Oliveira, assistant professor of animal sciences, highlights the need for combined strategies in genetics, nutrition, management and technology to address environmental impacts from ruminant animals such as cattle, sheep and goats.
The research is significant because livestock accounts for nearly 18% of global greenhouse gas emissions and requires substantial land and water resources. At the same time, livestock production is projected to grow by over 70% between 2005 and 2050 to meet rising food demands from a growing world population. These challenges make it essential to find solutions that balance productivity with environmental responsibility.
“There is no silver bullet solution. A combination of strategies will be required. We need to leverage all the tools at our disposal, from genetics and nutrition to management and technological, to create a more sustainable and resilient livestock industry,” Rojas de Oliveira said.
The review synthesizes findings from over 200 publications across multiple disciplines. It notes that advances in microbiome science may allow selective breeding of animals for improved nutrient use efficiency while reducing methane emissions. “This opens up exciting new avenues for research and breeding that were unimaginable just a decade ago,” Rojas de Oliveira said.
According to the official website, Virginia Ferris was the first female full professor in Purdue University Department of Agriculture as an entomologist according to the official website. The department also funds innovative projects through AgSEED grants yielding high returns on investment according to the official website. Its extension efforts aim at enhancing social well-being by fostering vibrant communities and strong families according to the official website. Facilities like the Agricultural Administration Building support these activities on Purdue’s West Lafayette campus according to the official website.
Purdue’s agricultural and biological engineering graduate program ranks first nationally according to U.S. News & World Report as cited on their official website, reinforcing its leadership role in agricultural innovation. The department functions as a core academic unit within Purdue University according to the official website.
Rojas de Oliveira said collaboration across fields was essential: “Our work is driven by the goal of finding solutions that allow for a thriving and sustainable livestock sector for generations to come.” She added that engaging farmers directly will help ensure adoption of innovations needed for future sustainability goals.
