Successful farmers use and refine grazing systems to improve the productivity of their
pastures.
This, in turn, helps them improve their animal and pasture performance.
Hi, I’m Ollie from Pasture.io, and today we’re going to discuss the pros and cons
of three grazing strategies.
And we’ll talk about how herbage-data based rotational grazing can help you improve productivity.
Let's begin with the three grazing systems.
Grazing system number one.
Continuous grazing.
In a continuous grazing system, your animals graze a pasture continuously over a period
of time.
In this system, your pasture doesn't get any rest period.
Continuous grazing systems don’t require you to keep farm records.
It doesn’t require additional fencing or paddock setup costs.
And it doesn’t require you to actively manage your pastures.
However, these advantages come at a steep price because the disadvantages of continuous
grazing systems include low pasture yields, low nutritional value, degrading pasture quality
and poor animal health outcomes.
That said, a continuous grazing system may work well for farms with low stocking densities.
Farms that have a lot of grazing area and a small herd size.
It also may work well for small scale hobby farms with a larger ratio of dry cows.
However, if you’re a commercial farmer, you’ll need high-quality forage to increase
production as well as profits.
So continuous grazing might not be the best system for your needs.
Grazing system number two.
Sequential Rotational Grazing System.
In this system, the grazing area divides into roughly equal-sized paddocks, and livestock
animals rotate between each paddock in a set sequence after a set time.
So, when the last paddock of the sequence has been grazed, the first paddock that has
been given a good amount of time to rest is grazed next.
This rest period allows your pasture to recover from the previous grazing event and allows
enough growth to withstand the next grazing event.
The system works better for farms that receive an annual rainfall of over 800mm and access
to irrigation for the drier months.
Under these conditions, sequential rotational grazing offers higher pasture yields with
high stocking densities without compromising pasture quality.
However, implementing this system requires more upfront investments to create fenced
paddock areas with access to a stock water supply.
However, sequential rotational grazing doesn't consider variables such as weather, fertility
and soil moisture.
And leaves out a lot of opportunities to improve production.
To optimise annual herbage yields and production, you need to look at the third grazing system.
Herbage based rotational grazing.
This system rotates paddocks based on their herbage growth rate and not in a set sequence
because each paddock has different regrowth rates based on its soil fertility, slope,
irrigation and drainage.
This grazing system offers several advantages: + higher yields,
+ stocking densities, + nutrition intakes, and
+ quality pastures.
You get better yields because this system considers factors such as grazing, fertility,
moisture, seasons that impact your pasture growth rate.
It also helps you meet the nutritional needs of your herd without compromising pasture
growth.
