A more thorough explanation:

The Grain Inspection, Packers, and Stockyards Administration (GIPSA) is an agency within the United States Department of Agriculture (USDA) that is responsible for promoting fair trade practices and helping to market meat, cereals, and other agricultural products.

For example, GIPSA may inspect grain to ensure that it meets certain quality standards before it is sold. They may also investigate complaints of unfair practices in the meatpacking industry, such as price discrimination or anti-competitive behavior.

Overall, GIPSA plays an important role in ensuring that agricultural markets are fair and transparent, which helps to protect both farmers and consumers.
