What is the role of a teaser animal in detecting heat in cattle?

The role of a teaser animal in detecting heat in cattle is primarily focused on identifying female readiness for mating. Teaser animals, often vasectomized bulls or steers, are introduced to the herd to interact with females that may be in estrus. They exhibit behavioral changes that signal the presence of a receptive female, such as increased activity levels, vocalization, and mounting behavior. These behaviors serve as indicators for the livestock manager that the females are ready for breeding.

Utilizing a teaser animal is an effective strategy in a breeding program as it allows for timely breeding decisions, ensuring that the females are inseminated at the optimal time, which can enhance overall reproductive efficiency in the herd. The other options, while related to cattle management, do not pertain to the specific role of a teaser animal in the context of heat detection and mating readiness.
