Worming your dairy cows can be a complex issue as there is a need to consider the responsible use of anthelmintics and the environment whilst ensuring efficiency for milk production.
It is important that the use of anthelmintics is done responsibly to prevent the emergence of resistance.
Adult cattle may be sub-clinically affected by gut worms as well as lungworm. There are differences in the immunity cattle develop to both gut and lungworm and so different approaches can be necessary to maintain health and productivity.
Dairy cattle with Ostertagia ostertagi (gut worm) infections can have decreased milk production from their potential due to damage to the stomach and the subsequent negative impact on feed intake and digestion. Following treatment with a wormer, the increase in yield is variable with data from 0.35 – 2.35kg per day. It is known that higher yielding cows appear to be more susceptible to the effects of gastrointestinal nematodes.
