What should be established to ensure sheep biosecurity?

Establishing specific entry protocols for new sheep is crucial for ensuring biosecurity within a flock. These protocols typically involve quarantining new animals before introducing them to the existing herd, allowing time to monitor for signs of disease and ensuring they are healthy. This practice helps prevent the potential spread of pathogens that new sheep might carry, even if they appear healthy. By controlling and managing the introduction of new animals, farmers can significantly reduce the risk of infectious diseases entering their flocks.

Other options do not address the fundamental need for disease prevention. Regular public exhibitions can increase the risk of exposure to pathogens from a broader population, open grazing in communal fields can facilitate the spread of diseases among flocks, and discount pricing on feed does not have any direct impact on biosecurity practices or health protocols. Implementing specific entry protocols is key to maintaining the overall health and productivity of sheep populations.
