Which of the following is a biosecurity measure for cattle?

Biosecurity measures are essential practices aimed at preventing the introduction and spread of diseases within livestock populations. Cattle farms implement a range of strategies to protect the health of the animals and maintain biosecurity.

The practice of sanitation, isolation, and traffic control is critical in this context. Sanitation efforts involve keeping the environment clean from pathogens and contaminants that could affect cattle health. Isolation refers to separating new or sick animals from the herd to prevent disease transmission. Traffic control involves managing the movement of people and vehicles on the farm to minimize the risk of spreading infections. These practices together create a protective barrier against various diseases and ensure the overall biosecurity of the cattle herd.

Other practices mentioned, such as feeding schedules, health check-ups, and breeding programs, play important roles in the management of cattle but do not constitute complete biosecurity measures. Feeding schedules help in nutritional management, health check-ups are important for early disease detection, and breeding programs focus on genetic improvement. However, without strong biosecurity measures focused on sanitation and control, these practices alone would not sufficiently protect the herd from external threats.
