Individual goats which required more frequent worming were culled. Internal parasites are a greater problem in warm, wet climates. Yet, I personally know several individuals whose Boer goats succumbed to parasites faster than other breeds. Fortunately, certain goats have a genetically occurring immunity or “resistance” to internal parasites. I hope that parasite resistance in goats will become a more wide-spread goal before then. In fall 2011, Lincoln University (in Missouri) began a divergent selection program for parasite resistance in goats. They were bred to be adaptable and many African breeds hold true to their hardy reputation. If one worms too often, one is breeding superior worms, not better goats. But if not, then maybe there will be enough savvy producers to supply the market with parasite resistant livestock. Good parasite control includes four basics: under stocking, good sanitation, adequate nutrition, and selecting animals with a genetic resistance to parasites. Good parasite resistance in goats allows them to stay healthy and strong in order to care for themselves and raise their kids without adding economic strain to the rancher. Researchers assigned 146 mixed-age Boer and high-percentage Boer does to one of two divergent selection lines: low parasite resistance and high parasite resistance. Over a ten year period, we have achieved enough genetic improvement for parasite resistance to be able to worm only once per year. There are mixed experiences about the hardiness of Boer goats. If you wish to raise goats in such an area, we highly recommend you learn as much as possible about management practices for reducing internal parasite problems. When we first started breeding Boer goats for parasite resistance, we had to worm our goats three times per year.
