Marking Crayons Blue

These blue marking crayons are designed for use with compatible leather bull marking harnesses. They create a visible coloured mark on the cow's back during mounting, helping farmers track breeding activity more clearly during the service period. Keeping spare crayons on hand is important because blocks wear through regular use, especially in active breeding groups. Different colours can also help when separating breeding periods or bulls. For Irish farms relying on natural service, simple marking consumables like this play an important role in everyday breeding management.
