I would carry on with your worm counts, that will tell you when you need to worm. I don't know much about horses, but if they are anything like sheep, if you move them onto fresh ground regularly then the worm count should reduce, especially if the worm infective stage is about 3 weeks, and you move them on at 17 day intevals, then the infective stage larva is left standing without a host, and although some survive at that infective stage not all will. Some larvae are able to over winter. Although not always true, drier conditions may contribute to reducing the worm burden. Ideally you want to take a hay cut to break the cycle, and also mixed grazing and alternate grazing of species will help reduce infection of some worms. By the sound of your set up the worm count should be low as they have so much to graze that the % eaten of infective worm larva must be very low. I am afraid I am not up to speed with individual worms, its 40 odd years ago that I was genned up! |
