How cows eat grass can help the land and grow more food
INTEGRATED ANALYSIS OF SOIL–PLANT–ANIMAL DYNAMICS IN CONVENTIONAL AND VOISIN GRAZING SYSTEMS

When cows are moved around in a smart way (called Voisin Grazing), the grass grows better, there are fewer weeds, and cows gain more weight than when they stay in one place all the time.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

If you keep chickens on the same pasture all the time without rotating it, the soil gets worse, the grass doesn't grow as well, and there are fewer bugs and plants for the chickens to eat.
Using a smart grazing method called Voisin Rational Grazing can boost grass growth by over 30% in Brazil’s pastures, meaning more food for cows and other animals in similar climates.
Using a smart grazing method called Voisin Rational Grazing might cut down weeds in tropical pastures by 16%, making the grass healthier and easier to manage than if animals just graze all the time.
Using a smarter grazing method called Voisin Rational Grazing might help more types of grass grow in Brazilian pastures, especially two kinds called Brachiaria brizantha and Panicum maximum, compared to how most farmers graze their animals.
Cows on a smarter grazing system in Brazil gain more weight each day than cows on traditional grazing — about 0.78 vs. 0.58 kg per day — which means they're growing better with this new approach.
