The Accuracy and Informativeness of Agricultural Baselines

May 04, 2021

By Siddhartha Bora

United States Department of Agriculture (USDA) and Food and Agricultural Policy Research Institute (FAPRI), University of Missouri are two main sources of baseline projections for US agricultural sector. Published in the beginning of each year, the baselines provide insight about factors influencing the agricultural sector for the next decade. The projections present a conditional scenario based on certain assumptions about macro-economy, weather, and trade, and serve a basis for comparison of alternative policies. In a new study, we evaluate the accuracy and informativeness of USDA and FAPRI baselines since 1997. We find that the predictive content of most variables in the projections diminish after 4-5 years from the current year, and the USDA and FAPRI models do not outperform one another when entire projection path is considered.

Video: What Happens When Pigs Adapt to High Soybean Meal Diets? - Gustavo Lima

In this special rerun episode of The Swine Nutrition Blackbelt Podcast, Gustavo Lima, PhD candidate in Animal Science at Iowa State University, discusses how grow-finish pigs respond to high soybean meal diets. He explains the initial drop in feed intake, changes in backfat, later adaptation, energy efficiency, amino acid utilization, and the rise in nitrogen excretion at higher inclusion levels.

“Once they got adapted to the diet, they can handle higher levels of inclusion of soybean meal.”
