Overview
A grazing event records a mob grazing one or more paddocks on a particular date. Record the pre-graze and post-graze cover and the area grazed, and Trev calculates the pasture consumed. If you select a mob, Trev also shows the pasture consumed per animal.
This article covers Trev on the web. You can also record grazing events in the Trev app.
Before you start
Your farm needs the Land module enabled and paddocks set up on the farm map.
Most user types (Full Access, Authorised, Editor, Reporter) can log grazing events. Reporters can only do it within the current reporting period, before the report's submitted. The other three can also log past events, outside that window.
If you want to link the event to a mob, there needs to be a weekly report covering that date with the mob recorded in it. You can still save a grazing event without selecting a mob.
Record a grazing event
Click the Quick Add menu (+) in the top right corner of Trev.
Select Paddock Walk Event
Select Grazing Event
Choose the farm, if you have access to more than one.
Choose the date & time of day. Trev defaults to today.
Choose All Day, AM or PM.
Choose the mob from the Mob dropdown, if you want to link the grazing event to a mob. The list only shows mobs recorded for the farm on that date.
Choose the paddock in the paddock card.
Check the Pre-graze cover. Trev pre-fills this from the paddock’s latest known cover and shows the source underneath. Update it if you have a more recent reading.
Enter the Post-graze cover. Trev defaults this to 1500 kgDM/ha, so update it to the actual post-graze cover if needed.
Enter the Area grazed. It starts at 100%. To enter the area in hectares instead, choose ha from the unit dropdown.
If only part of the paddock was grazed and the mob was back fenced, tick Backfenced. This option appears when the area grazed is less than the whole paddock.
Enter any Stand-off hours and a Note, if needed.
Click Save Event.
Important: A mob can only have one grazing event in each half of the day. An All Day event uses both AM and PM, so you can’t also add an AM or PM grazing event for the same mob on that date.
Graze more than one paddock
If the mob grazed more than one paddock during the same grazing event, add all of the paddocks to the same event.
Click Add paddock under the last paddock card.
Choose the next paddock and enter its covers and area grazed.
Repeat for each paddock, then click Save Event.
Each paddock card shows its own Consumed figure. The Pasture consumed summary below the cards shows the total for the event. To remove a paddock, click the bin icon in the top right of its card.
What to expect
After you save, Trev shows a Grazing event created message and closes the form.
The post-graze cover you record becomes that paddock’s latest known cover until a newer cover is recorded. Trev can then offer that figure as the pre-graze cover the next time you record a grazing event for the paddock, with the source shown underneath.
Handy tips!
The Pasture consumed figures update as you enter the covers and area grazed. Use them as a sense-check before saving; the area grazed should reflect the area the mob actually grazed.
Switching between % and ha converts the area for you. For example, 50% of a 4.35 ha paddock becomes 2.18 ha.
