Abstract


Endoparasites are those organisms living within their host in the gut, body cavities, liver, lungs, gall bladder and blood or within intercellular spaces, tissues or cells of the host. Since they totally depend upon their host, endoparasitism is also referred to as infection (Bilma, 2009). The most important and widely prevalent nematodes are Oestertagia sp., Trichostrongylus sp. and Oesophagostomum sp. in cattle and buffaloes (Karki, 2005). During the dry season, shortages of fodder place many animals under nutritional stress, which can influence the severity of gastrointestinal infection (Fritsche et al., 1993). The general health of the animal such as reduction in blood haemoglobin concentration (Lassisi et al., 2001) and packed cell volume (PCV), red blood cells and total serum protein were also observed by Reyaz et al. (2007).
