Parasitic diseases in livestock cause great economic losses every year, sometimes by direct loss of animal lives or by loss of production performance. One direct way of control of gastro-intestinal nematodes is by using anthelmintic drugs either as single or as multiple combination compounds. However, disproportionate use of these compounds has constrains in being expensive and development of anthelmintic resistance in parasites. Therefore, alternative strategies for worm control needs to be developed that could not only reduce worm burden in animals but can also limit pasture contamination and reduce chances of drug resistance. Development of breeds/strains of sheep and goat that are naturally resistant to Haemonchosis appear to be the suitable method for worm control as it lowers the chances of drug resistance and residue and is more sustainable as compared to other methods in the context of rapidly changing climatic conditions.
