With the drier conditions up to now, parasite eggs and larvae would have found it harder to survive due to the lack of moisture needed for their development. Those that did reach the larval stage burrow into the soil and wait for the rain. Now the rain has arrived, large numbers of larvae can quickly emerge from the soil and faeces on the pasture. This explosion means a high contamination of larvae on short pasture and so the ingestion of larvae by stock is likely to be very high.
Keep an eye on your young stock as parasitism may occur a lot quicker than you think. If concerned then take samples for a FEC or contact us for a drenching strategy.
