liver fluke in great britain: a survey of affected livers.over a period of 15 months data were collected from abattoirs in great britain on 213,082 cattle and 362,838 sheep livers to determine the distribution and prevalence of damage by fasciola hepatica. the stock came from 8239 farms, and from livestock markets in 81 counties. 53 per cent of the farms had sent affected stock, with significant percentages in eastern as well as the western counties of england and scotland. 21 per cent of all cattle and 7 per cent of all sheep livers examined were affe ...19751202744
epidemiological studies on nematodirus species in sheep.faecal egg count and pasture larval studies on n battus and n filicollis in lambs showed distinct differences in epidemiology, the infective larvae of n battus hatching over a short restricted period in spring, whereas those of n filicollis show an extended period of hatching, beginning in autumn and increasing steadily through the winter to reach a spring peak. this difference was considered to be responsible for the much slower annual rate of increase recorded for n filicollis. pasture infecti ...19751215676
parasitic otitis in sheep associated with psoroptes infestation: a clinical and epidemiological study.parasitic otitis associated with psoroptes infestation was diagnosed in a small pedigree flock of sheep with aural haematomas, abscessation and cauliflower ears. thirteen of the 15 lambs were affected but the clinical signs were mild; small, discrete, crusty lesions on the inner aspect of the ear at the junction of its anterior and posterior borders were typical. nine of the 20 adults were affected but the lesions were more severe. eighteen of the 64 members of the breed society who responded to ...19921441096
evidence of multiple anthelmintic resistance in a strain of teladorsagia circumcincta (ostertagia circumcincta) isolated from goats in scotland.the efficacy of ivermectin, fenbendazole and levamisole was determined in lambs individually infected with 5000 third stage larvae of teladorsagia (ostertagia) species isolated from a herd of goats with a history of benzimidazole resistance and where the efficacy of ivermectin had also suffered an apparent decline. efficacies, calculated using geometric means, for groups where treatments were directed against adult worms were 90.3 per cent (ivermectin), 43.4 per cent (fenbendazole) and 100 per c ...19921465512
a speculative discussion of some problems arising from the use of ammonium nitrate fertiliser on acid soil.some personal farming experiences are described, and attention is drawn to four anomalies associated with the use of ammonium nitrate. these can be explained if the changes that took place in the formulation of fertilisers around 1960 have led to acidic soils becoming depleted in calcium, and if crops growing in high nitrogen conditions take up their nitrogen as ammonium. it is concluded that the fertiliser recommendations that have been formulated at rothamsted are unsuitable for use upon acidi ...19921488214
