Cross-sectional Prevalence of Helminth Infections in Cattle on Traditional, Small-scale and Large-scale Dairy Farms in Iringa District, Tanzania
Results indicated that the type of management, especially the grazing habit, has a significant influence on the prevalence and intensity of GI nematodes and flukes and the variation in the prevalence among management and age groups within systems can be used as an entry point towards rational use of anthelmintics for each management system.
The Prevalence and Intensity of Helminth and Coccidial Infections in Dairy Cattle in Central Kenya
A survey of gastrointestinal parasite infections of young, immature and adult dairy cattle on 16 farms in Kiambu District, Kenya was conducted during a dry season and during a wet season, finding a higher intensity of infection with strongyles and coccidia was found in the wet season than in the dry season.
A Comparison of the Prevalence and Burdens of Helminth Infections in Growers and Adult Free-Range Chickens
There was an interaction effect such that growing males and adult females had statistically higher burdens of T. fissispina and T. tenuis and A. suctoria, respectively, and the sex of the chickens influenced the burdens of Heterakis brevispiculum.
Epidemiology of Fasciola gigantica and Amphistomes in Cattle on Traditional, Small-scale Dairy and Large-scale Dairy Farms in the Southern Highlands of Tanzania
The proportion of animals passing fluke eggs increased gradually from the early dry season and peaked at the end of the drySeason and the early part of the rainy season, indicating a significant influence of the type of management on the prevalence of both Fasciola and amphistomes.
Bovine cysticercosis in Denmark. A study of possible causes of infection in farms with heavily infected animals.
Epidemiological studies were made on 14 farms from which, during a 2 year period, 38 cattle had been condemned at slaughter, due to massive infections with Cysticercus bovis, finding the most frequent sources of infection to be sludge from septic tanks illegally applied on pasture or crops, in some cases after having been mixed with animal slurry.
Temporal changes and risk factors for foot-pad dermatitis in Danish broilers.
The analysis showed that flock lesion scores increased when the litter quality was evaluated as poor during the on-site antemortem evaluation, and other significant risk factors were winter season as opposed to summer, low daily weight gain, straw as bedding material in contrast to wood shavings and sphagnum peat, and high age at slaughter.
