Cross-infection of gastrointestinal nematodes between winter corralled semi-domesticated reindeer (Rangifer tarandus tarandus) and sheep (Ovis aries)
The increasing number of sheep (Ovis aries) in the reindeer (Rangifer tarandus tarandus) herding area in North Finland and supplementary winter feeding of reindeer in corrals shared with sheep causes potential for crossinfection of gastrointestinal nematodes between reindeer and sheep. The aim of this study was to elucidate this potential. The study included 46 animals, of which 12 reindeer and...
متن کاملUse of Microsatellite Polymorphisms in Ovar-DRB1 Gene for Identifying Genetic Resistance in Fat-Tailed Ghezel Sheep to Gastrointestinal Nematodes
This study was designed to identify genetically resistant animals to gastrointestinal nematode (GIN) infections using microsatellite polymorphisms of Ovar-DRB1 gene in Iranian Ghezel sheep breed lambs. In the present study 120 male Ghezel lambs were at 4 to 6 months of age randomly selected from six different sheep flocks in East Azerbaijan province (n=20 per flock). These lambs were naturally ...
متن کاملPoint Prevalence of Gastrointestinal Parasites of Domestic Sheep (ovis Aries) in District Sialkot, Punjab, Pakistan
In Pakistan, parasitic infections are among major constraints to animal production. Gastro-intestinal (GI) parasites cause huge economic losses (direct or indirect) to livestock. In Pakistan, distribution and effect of GI parasitism in sheep is not very well studied. The present study was conducted to determine the prevalence of GI parasites in sheep population of Sialkot district, Punjab, Paki...
متن کاملA survey on the occurrence of resistance to anthelmintics of gastrointestinal nematodes of goats in Mozambique.
A survey to study the extent of anthelmintic resistance was conducted in Maputo and Gaza, two of the ten provinces of Mozambique, during February and March, 1999. A total of 12 flocks, six in Maputo and six in Gaza, was surveyed. The faecal egg count reduction test was used to assess the efficacy of three anthelmintics most often used in Mozambique, namely albendazole, fenbendazole and levamiso...
متن کاملCardiotoxicity of Senna occidentalis in sheep (Ovis aries)
The cardiotoxicity of Coffee senna (Senna occidentalis) was investigated in sheep that were fed diets containing its seeds, which are recognized as the most poisonous part of such weed. Dianthrone, the main toxic component of S. occidentalis, is known to impair mitochondrial oxidative phosphorylation, leading to myofiber degeneration. In this study, fifteen ewes were fed 0%, 2% or 4% of seeds o...
