Endoparasites or internal parasites live inside the host and are classified according to their localization as blood, tissue or intestinal parasites. A certain basic set of parasites is given to the foals by the mother, they ingest them with the mother's faeces.
That's how nature arranged it. It should also make us think that diseases such as neurodermatitis, asthma and allergies are almost unknown in developing countries with low hygiene standards and high parasite loads. In the human area, allergists use the pork whipworm to treat chronic intestinal inflammation and food intolerance.
No, we do not want to protect strongyles, roundworms and other intestinal parasites. But wormers should not be used indiscriminately either. They put a strain on the liver and intestinal flora. If we have to fight, we should not choose the intervals too short and use the natural possibilities of stabilizing the intestinal environment to strengthen the body's immune response to parasites and prevent the development of resistance. With all wormers it should always be considered that the dead worms have to leave the intestines and that decomposition products and cadaveric toxins burden the metabolism just as much as the chemical agents themselves.
