Calendar for animal husbandry - indicates which animals must be treated on given dates

摘要

The calendar has a data scale such as a rotatable ring aligned with a scale of operations to be performed on each animal. The data scale is provided with spaces for insertion of animal identification numbers, so that the user is reminded to carry out the same operations on different animals with the same time intervals between these operations. The preferred design has two concentric scales with the outer ring for January-June and the inner for July-December.
