Dung samples were also tested for Haemonchosis. The results showed that monsoons showed higher mortality with higher Hemonchus infectivity than summer season. Every one unit of blood urea nitrogen increased, 0.953 times mortality decreased. And every one unit of globulin increased, 0.0163 times of mortality decreased, because of higher antibody titer level by active infection/ immunization. Every one unit of albumin increased, 0.0004 times of mortality was decreased. Plasma protein estimation provides better insights into herd health investigations in ovine.EnglishVeterinary ScienceAnimal Genetics and BreedingArticle
