Rotational grazing systems are great for keeping pastures healthy and boosting livestock productivity. By giving grass time to recover between grazing periods, they help maintain strong plant growth and prevent soil damage.
In this episode, we explore the benefits of rotational grazing systems and how they improve pasture health and livestock productivity. We look at important factors like the number of animals per area, how long pastures need to recover, and how sustainable rotational grazing is for different types of livestock and more.
Ntokozo Msiza, PhD candidate in animal science specialising in grass species selection for pasture management, is back with more tips on rotational grazing techniques. This time, she highlights the primary benefits of rotational grazing systems, and how it influences stocking rates.
“Stocking rate is the number of animals or livestock units that are grazing a specific unit of land over a certain period of time. This is usually expressed as the number of animals per hectare. The stocking rate is a very critical factor in pasture management as it determines the balance between forage availability and animal demand, which then ensures sustainable pasture use and optimal livestock productivity.”

Msiza provides additional details on the consequences of having stocking rates that are too high or too low. Determining the appropriate stocking rates for different livestock is also discussed in this episode.
Optimal recovery periods
Msiza explains that the optimal recovery period for grazing land depends on the type of pastures it contains. Are they cool-season or warm-season pastures, or perhaps a mix of both?
She discusses various types of grasses to consider and how much time each would need to recover in order to regrow effectively.
“When you allow a particular period for the pastures to regrow, you are reducing the stress on the plants and the animals as well. With different grasses and pasture legumes we need to know the different growth rates and the recovery it needs so that we can be able to find a balance between us allowing these pastures to rest and allowing these pastures to give what these animals need for nutrition,” Msiza says.
