“…The study has indicated that most adults and weanlings had FECs below the cut o¡ point of 500 epg for salvage anthelmintic treatments (Keyyu, 2004). The low FEC, especially in adult cattle, concurs with other studies (Stuedemann et al, 1989;Couvillion et al, 1996;Nodtvedt et al, 2002). The higher FEC in calves than adults concurs with other studies (Snyder, 1993;Anene et al, 1994).…”

Cross-sectional Prevalence of Helminth Infections in Cattle on Traditional, Small-scale and Large-scale Dairy Farms in Iringa District, Tanzania

et al. 2006

A cross-sectional study was carried out to determine the prevalence of gastrointestinal (GI) nematodes and flukes (Fasciola and amphistomes) infection in communally grazed traditional cattle, zero-grazed small-scale dairy cattle and intensively grazed large-scale dairy cattle through examination of helminth eggs in faeces. 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. The prevalence of GI nematodes in traditional, large-scale dairy and small-scale dairy cattle was 67%, 44.4% and 37%, respectively, with the highest faecal egg counts in calves. The overall prevalence of Fasciola gigantica in traditional, large-scale dairy and small-scale dairy cattle was 63.8%, 46.2% and 28.4%, respectively. The prevalence of amphistomes was 81.9%, 55.5% and 41.1% in traditional, large-scale dairy and small-scale dairy cattle, respectively. The high prevalence of flukes in the traditional system was attributed to communal grazing and watering management practices. Stomach flukes recovered in examined cattle at the abattoir were Calicophoron microbothrium and Cotylophoron jacksoni. About 42.1% of infected animals had both Fasciola and amphistomes. The prevalence of both GI nematodes and flukes varied greatly among villages and farms. The prevalence of both Fasciola and amphistomes was higher in adults (58.5%, 75.2%) than in yearlings (36.5%, 51.5%) or calves (24.9%, 47.2%). The variation in the prevalence of both GI nematodes and flukes among management and age groups within systems can be used as an entry point towards rational use of anthelmintics for each management system. More studies on seasonal transmission pattern of all these parasites are required in order to design rational, economic and locally sustainable parasite control programmes.

“…It is known that economic losses can be avoided through the correct use of anthelmintics (Stuedemann et al, 1989;Stromberg, 1997;Williams et al, 1997). However, these drugs are often administered without taking into account regional variables.…”

The objective of the present study was to determine the dynamics of infestation of cattle and pasture by gastrointestinal nematodes in a mild humid environment in northwestern Spain. For this, infestation of pasture by free-living stages (L3), dynamics of faecal egg output, blood pepsinogen levels and worm burden in slaughtered animals were quantified. The results showed a high degree of annual variability, which was dependent on weather conditions. The seasons were clearly defined in the study area, with mild humid winters and relatively dry summers registered throughout the years of the study. Infestation of pasture by larvae varied from year to year, peaking during August in the first year, between August and December in the second year, and during October in the third year. The annual variation was mainly due to weather conditions, particularly the amount of rain in summer. The patterns of faecal egg output were similar in the first and third grazing seasons, with maximum levels observed in May/June; however, in the second year, the peak was reached in October. Blood pepsinogen levels increased from pasture turnout (March/April) until the end of the grazing season (November/December), reaching maximum values from August/September onwards. The nematode parasite species identified at necropsy were Ostertagia osteragi, O. lyrata, Cooperia oncophora, C. macmasteri, C. punctata and Trichuris ovis, with O. ostertagi and C. oncophora predominating. In faecal cultures, the following genera were also identified: Haemonchus, Trichostrongylus, Nematodirus, Bunostomum, Oesophagostomum and Strongyloides. There was a significant correlation (r=0.97, P<0.01) between worm burden (Ostertagia spp.) and pasture infestation (Ostertagia L3) 3 weeks prior to slaughter of the calves, and also between blood pepsinogen levels and pasture infestation by Ostertagia L3 (r=0.33, P<0.02). Correlations between worm burden and faecal egg output and between blood pepsinogen level and faecal egg output were not significant. The results obtained in the present study confirm that there is annual variability in the time-course of nematodosis in cattle, and demonstrate the importance of weather, particularly summer rainfall, in an Atlantic temperate environment.

“…Fenbendazole acts by disrupting energy metabolism in worms by binding to parasite tubulin, a constituent protein present in microtubules and in plasma and mitochondrial membranes whereas praziquantel modulates cell membrane permeability causing spastic paralysis of muscle cells in the parasite (Taylor et al 2007). The efficacy of fenbendazole against T. vitulorum infection in calves has already been reported by various workers (Stuedemann et al 1989;Davila et al 2010). Hafiz et al (2010) has reported 85.41 % efficacy of fenbendazole against T. vitulorum in calves from Srinagar city of Kashmir Valley.…”

The present clinical case reports toxocariosis in a suckling calf and its management. One and a half month old crossbred Jersey calf was presented at a Veterinary Clinics, District Pulwama, Kashmir with a history of intermittent diarrhea, poor growth, weakness, moderate dehydration and anorexia. On inspection, the calf showed normal physiological parameters viz; body temperature, pulse rate and respiration rate. On faecal examination, eggs of Toxocara vitulorum were found. The animal was treated with 30 ml suspension of 1.5 % fenbendazole ? 0.5 % praziquantel orally. After examination of faecal samples on 7th and 14th day post treatment no T. vitulorum eggs were observed.
