Every grazing event in PastureMap is tied to a single pasture or subdivision. This allows PastureMap to accurately calculate the productivity of each pasture or subdivision. Sometimes you may have a herd grazing in multiple pastures. For example, this can happen because you opened a gate between multiple pastures and the animals are grazing freely between them. There are a few ways you can record this in PastureMap.

Option 1. Adjust subdivisions

If a herd is grazing in two subdivisions and the two subdivisions are touching, you can adjust subdivisions and remove the fence line between the two subdivisions you want to graze together.

Option 2. Apportion grazing time between the two pastures

Let's say a herd grazes Pastures A and B together for 10 days. You can record this as two separate grazing events. First the herd grazed A for 5 days, then it grazed B for 5 days. This is assuming the herd grazed A and B equally.

To ensure the pasture productivity calculations are correct, you should make sure that the number of grazing days in each pasture is proportional the amount of forage your herd consumed from each pasture. For example, if you think your herd grazed Pasture A four times as much as pasture B, you should record this as grazing A for 8 days and B for 2 days (8 divided by 2 is 4).

Similarly, if the herd grazed three different pastures, you can record this as three separate grazing events of 3.33 days each.

Option 3. Split up your herd into multiple herds

Another option is to split and merge your herds. This is a little bit more work but allows you to keep more accurate records, especially if you want to more accurately keep track of the grazing start and end times and the number of animals in each pasture. This option works well if you are using the Sandhills calving system.

  • Let's say your herd has 100 animals and they are currently grazing in Pasture A. 

  • On June 1 you open up the gate and let 50 animals start grazing Pasture B. 

  • Then on June 5 you bring the remaining 50 animals into Pasture B.

To record this, you can do the following:

  1. Sort out 50 animals from your herd and put them into a new herd H2. See this article for more information.

  2. Move herd H2 into Pasture B on June 1.

  3. Move the remaining 50 animals from Pasture A into Pasture B on June 5.

You can keep the animals in two separate herds if you wish, or you can move animals from one herd to the other if you want to merge them. Make sure you don't delete the herd, or else you will lose the historical records associated with the temporary herd. You should retire the herd instead if you don't need to see it anymore.
