True or False: Anthelmintics should be administered to livestock on a monthly basis.

The statement that anthelmintics should be administered to livestock on a monthly basis is false because the frequency of treatment with anthelmintics relies on various factors including the specific parasitic threat, the effectiveness of the medication, the life cycle of the parasites, environmental conditions, and the overall health and management practices of the livestock.

Overusing anthelmintics can lead to the development of resistance among parasite populations, reducing the effectiveness of these treatments over time. In many cases, a strategic approach is preferred, which involves targeted treatment based on fecal egg counts or clinical signs of parasitism, rather than a blanket monthly treatment regime. This approach helps to manage the parasite load more effectively while minimizing the risk of resistance.

Additionally, the necessity for treatment can vary seasonally depending on environmental conditions that affect parasite transmission. For instance, certain parasites might have higher prevalence during warmer months, necessitating more frequent monitoring and treatment during that time.

Understanding these factors is crucial for effective livestock management and helps to optimize herd health while ensuring responsible use of anthelmintics.
