“…The results are in apparent contrast to those reported by some workers in the United States (Todd, Myers, Bliss and Cox, 1972;Bliss and Todd, 1974), Europe (Pouplard, 1978;Pluimers, 1979) and in the United Kingdom (Bliss, Jones and Conder, 1982;Michel et al 1982), who have described significant improvements in yield following nematocidal treatment. Factors that might contribute to this apparent discrepancy include the variability inherent in all milk production data, which tends to mask small responses to treatment, and factors such as the method of analysis, trial design, treatment regimen and farm management system.…”

A field study involving 1087 cows and 191 heifers on nine carefully selected English dairy farms was conducted to evaluate the effect of nematocidal treatment on subsequent milk production. As many of the cattle as possible were allocated to pairs according to specific criteria and dosed with either levamisole and oxyclozanide, or oxyclozanide alone, soon after calving. The remaining unpaired animals were assigned alternately to the two treatment groups according to calving date. The milk production and health status of all the cattle in the study were closely monitored.Analysis of pooled milk production data over a 2-year period failed to show a statistically significant response to nematocidal treatment. When individual herd data were analysed, a significant response to treatment was recorded on one farm. It was noted that the apparent value of the response varied according to method of analysis.Factors considered likely to account for differences in response between farms and also between trials are considered. 15

“…However, later trials have provided conflicting results, despite the use of large numbers of animals, with some workers reporting improvements in milk yield (e.g. McBeath et al 1979;Bliss et al 1982), whilst others have found no significant beneficial effects following treatment (Baker, 1979;Michel et al 1982). Very few experiments have been conducted in sheep to evaluate the impact of trichostrongylosis on milk production.…”

“…Reducing parasitism involves more than just treating cattle after they become infected. For seasonal control, environmental contamination must be minimised to prevent continued reinfection 10. The existence of infective larvae in the surroundings of cattle is even more damaging than their development within the cattle 11.…”

BackgroundIn Nepal, knowledge of proper handling, management and causes of cattle diseases is still limited. The main objective of this study was to explore the impact of deworming on milk production and its effect on milk qualities.MethodsA total of 200 faecal samples (100 buffaloes and 100 cows) were collected and analysed for parasitic burden. Half of the infected cattle (buffaloes, Bos bubalis; cow native, B indicus; European, B taurus) were then dewormed with Levamisole Hydrochloride-Oxyclozanide bolus, and the remaining 50 per cent were left untreated. The milk yield from both infected and dewormed cattle was recorded for 30 days and the qualities of milk were analysed.ResultsThe prevalence of parasitic infection was found to be 22.0 per cent. Fasciola hepatica was the predominant parasite (81.8 per cent), followed by Toxocara vitulorum (34.1 per cent), Strongyloidespapillosus (6.8 per cent) and Bunostomum phlebotomum (4.5 per cent). The average milk yield (litre/day/cow) significantly increased, which was 1.22 litres per day for treated cows and 1.06 litres for treated buffaloes. The intervention effect of deworming among cows was 0.79 (14.06 per cent increment) and for buffaloes was 0.42 (8.32 per cent increment). After deworming the infected cattle, the protein percentage was significantly improved in cows (P=0.035), whereas the lactose percentage and solid percentage had increased significantly in buffaloes (P=0.002 and P=0.028).ConclusionAntiparasitic treatment in cattle had positive effects on milk qualities such as solid non-fat, lactose, solid percentage and total protein percentage.
