Recognizing the Signs
Weight loss despite adequate feed, a rough coat, diarrhea, and reduced growth rates are common signs of internal parasite burden. External parasites like lice and flies often show up as excessive scratching or restlessness, and both problems quietly erode herd productivity long before they become obvious.
Deworming Strategy
Rather than deworming on a fixed calendar alone, many producers use fecal egg counts to check whether treatment is actually needed and to monitor resistance. Rotating between dewormer classes, rather than the same product repeatedly, helps slow resistance and keeps treatments effective longer.
Managing Flies and External Pests
Pour-on treatments, fly tags, and dust bags each target external parasites differently, and dragging pastures to break up manure piles reduces fly breeding grounds significantly. Rotational grazing also naturally interrupts many parasite life cycles by moving cattle off contaminated ground before larvae become infective.
Working With Your Vet
A veterinarian can help design a parasite control program suited to your region, herd size, and grazing system, since parasite pressure varies enormously by climate. Getting this right protects growth rates, fertility, and overall herd health.
