[Testing of a deworming scheme for XXXX ].

@entity3753 @entity3070 @entity1641 @entity277 @entity1017 @entity5294
In 1983 and 1984 the effect of a deworming scheme, in which @entity1641 were treated at turn out and 4 and 8 weeks later, on the egg output, larval differentiation, @entity1017 , herbage @entity277 and in 1984, the percentages of some serum proteins were tested. In 1983 the experiment was done with 42 mares, 54 two year old male @entity1641 and 42 male yearlings, kept in groups with permanent or rotational grazing. In 1984 only 90 male yearlings were investigated. In 1983 @entity3753 and @entity3070 were used, 1984 @entity3070 . The results of the faecal examinations showed that after @entity3070 treatment the number of eggs per gram faeces (EPG) remained zero or very low for a longer time. In 1983 an increase was seen during August. In 1984 the increase was observed at the end of August/beginning of September. Treatment with @entity3753 gave a less efficient suppression of egg output, resulting in a sharp EPG-increase at the end of July/beginning of August. After first treatment either with @entity3070 or @entity3753 , no larvae of great Strongyles were seen. The results of the herbage @entity277 on the paddocks were according to the EPGs of the @entity1641 that grazed the paddocks some time earlier. @entity277 was highest in late summer and autumn, lowest in early and mid summer. No significant differences in @entity1017 were observed between the groups. The percentage of beta 1 + 2-globulin was highest at turn out. After first treatment it decreased, but remained stable thereafter during the season, irrespective of the reinfection in autumn. Post-mortem results of four tracers in 1984 varied from ca. 275,000-2,000,000 small Strongyles. The conclusion was drawn that under the present conditions the system was not satisfactory to prevent a reasonable @entity5294 in late summer/autumn. The following advice was given: treatment of @entity1641 at least 48 hours before turn out, deworming each four weeks up till July, treatment in September and in November (also against Gasterophilus).
