Once a Farm Structure is created:
Click on the Recipe tab and the screen below shows the New Recipe + (you can also go to the existing farm, pen and right mouse click)
Then you can decide what ration and where you would like to build it from.
We will Use the DEMO Farm and build a High ration which you can see to the right the animal type is the Dairy Cow.
You are then taken to the Animal Inputs page underneath the New Recipe tab of your ration. These Parameters can be changed from the Main Tab and then Utility then Animal type defaults.
You can look and change the Animal type, Environment, and Activity here. Then go to the right of the Animal Inputs tab to the Recipe.
From the Recipe screen now you can add feeds from the upper left corner.
Then as you fill with feeds and put some amounts of the ingredients you will see the screen fill with the parameters of the ration.
Saving can be done by the tab circled.
