What is an example of an environmental management practice to control internal parasites?

1. Feeding an animal a balanced diet

2. Administering anti-parasitic drugs

3. Administering a vaccine

4. Removing or reducing manure from facilities

The correct answer is: Removing or reducing manure from facilities

An example of an environmental management practice to control internal parasites is the removal or reduction of manure from facilities. This practice is effective because many internal parasites have life cycles that depend on fecal matter for transmission. By minimizing the presence of manure, the likelihood of parasite eggs or larvae contaminating the environment is significantly reduced. This, in turn, lowers the risk of animals ingesting these parasites, thereby helping to control their population within a herd or flock. The other choices, while important for overall animal health, do not specifically target the environmental aspect of parasite control. Feeding an animal a balanced diet supports its overall health but does not directly affect parasite loads. Administering anti-parasitic drugs is a treatment strategy rather than an environmental management practice. Similarly, administering a vaccine can help prevent certain diseases but does not address internal parasites through environmental management. Therefore, focusing on manure management offers a proactive approach to reducing the risk of internal parasite infestation in livestock.
