Search for your mating pairs in the animal menu and select - click the Mating Action button. mLIMS will take you to the Add Mating tool with your animals pre-selected.
Selected Animals
When starting with selected animals in the Animal Menu, the breeding animals are already pre-selected for you. Skip the search/browse for dam and sire.
Use the radio buttons to either select an existing cage from the Active Cages Dropdown, or set up a new cage. If you set up a new cage, an add new cage tool will pop up. Complete the cage setup and save.
The options are selected for you by default. Keep selected to transfer the breeding animals to your selected or new cage, and verify that the cage is empty.
