A New Way to Predict Grazing Cattle Weight Gain on Rangelands From Satellite Imagery

Dec 20, 2021

By Maribel Alonso

USDA’s Agricultural Research Service (ARS) developed a unique approach to using satellite imagery to predict cattle weight gain on rangelands. By fusing multiple images over a period of time, scientists were able to monitor how forage quality changes over space and time in rangelands within the shortgrass steppe, and how this relates to the weight gain of free-ranging cattle throughout the summer grazing season.

Managing the grazing season in rangelands can be challenging due to high variability in temperature and rainfall over time. From a manager’s perspective, it is essential to know when and where forage production and quality are changing to optimize free-range livestock weight gain and meet other environmental objectives. This is not just about chasing forage quantity (total amount of vegetation biomass); it is also about looking for the highest-quality forage throughout the season.

Video: CEOs of the Industry: John McIntire, Partner at Pike Pig Systems

CEOs of the Industry, Jim sits down with John McIntire, Partner at Pike Pig Systems, one of the most quietly impressive 26,000-sow operations in the U.S. John shares how he grew from operator to partner, how Pike built a people-first culture with long-tenured managers, and why they’re committed to weaning bigger, stronger pigs at 25+ days.

John breaks down how Pike stays efficient in a tough economic environment, the power of their shareholder-owned farm model, and how their work with PIC and a 240-head boar facility drives genetics and health outcomes. He also opens up about the innovations Pike adopts — and how they decide what’s truly valuable versus industry hype.

From Prop 12 and labor challenges to trade, consumer expectations, and sustainability, John chooses a hot-button issue and shares how Pike is preparing for the future. The episode closes with a rapid-fire “Fast Five” — mindset, leadership, daily habits, and three words that define Pike Pig Systems in 2025.
