..In heifers, the proportion of CRD-positive calves in the herd was strongly associated with the proportion of test positives (S-Hp or fever; S-HP and fever), suggesting potential as a herd-level indicator...

..g., amount of concentrates and type of roughage given) were associated with VTCM at -7 to 30 d post-calving or elevated SCC at first test milking in the univariate analyses...

..No effect of clinical status on milk consumption was detected. The number of unrewarded visits was the most sensitive of the 4 feeding behaviors monitored to indicate clinical disease in calves fed restricted milk volumes...

..We concluded that housing calves in groups of under 10 calves is preferable from a health and growth perspective...

..Kaplan-Meier curves suggested that housing in small-group pens was associated with the lowest mortality (other housing systems were single pens and large-group pens with automatic milk feeders), but the association was not significant...

..It was concluded that rearing factors and calfhood health status can influence first lactation milk production...

..In the older calves there was a tendency for the untreated calves to gain more weight than treated calves...

..It is concluded that making hay from pastures contaminated with oocysts of E. alabamensis is unsatisfactory if the hay is to be used for feeding young cattle...

..Of the total variation in CI, 9.5% was due to herd factors and 12% to cow factors, as opposed to variation between lactations...

..The total mean costs of VRCM were estimated to be $735 per lactation with a diagnosis of CM, $103 per lactation across all cows, or $95 per cow annually during lifetime...

..Prophylactic anthelmintic treatment was used by 65% of the herds. The most common diet for replacement heifers before calving was a combination of grain, hay and silage...

..BVDV infections were restricted to a few herds, reflecting the effect of a voluntary control program against BVDV in Sweden...

..Both parasites have suggested zoonotic potential and thus warrant further attention. In addition, rotavirus is a major pathogen in neonatal enteritis in Sweden, whereas coronavirus and E. coli K99+ seem to be of less importance...

..Slightly more than 60 per cent of the treatments were given by the farmers without prior consultation with a veterinary surgeon...

..The prevalence of the target condition (in this case, decreased fertility) also influences test usefulness and should be considered when planning test systems and interpreting test results...

..However, cows in the GLY group tended to get their FAI later compared with cows in the control group but without at subsequent delaying of time to CON...

..In conclusion, supplementation with GLY in early lactation did increase milk yield without a subsequent decrease of metabolic status, and supplementation with PG tended to do the same...

..The association between social position, living environment and nasal symptoms is inconsistent. We wanted to test how living environment, occupation and social position were associated with nasal symptoms...

..All of the tested dytiscids consumed large numbers of prey. Since some dytiscid species can efficiently decrease populations of mosquito larvae, they are probably important in the natural control of these dipterans...

..The care programme has had a rapid and almost complete nation-wide penetration, and h as created the desired uniformity allowing proper analyses. The treatment results also appear comparable with specialised referral centres...

..The high relative risks of small cell and squamous cell carcinoma associated with smoking may have implications for risk assessments regarding passive smoking...
