Comparison of Ketosis, Clinical Mastitis, Somatic Cell Count, and Reproductive Performance between Free Stall and Tie Stall Barns in Norwegian Dairy Herds with Automatic Feeding
Sammenligning av ketose, klinisk mastitt, somatisk celletall og reproduksjonsstatus mellom båsfjøs og løsdriftsfjøs i norske storfebesetninger med automatisk kraftfôrtildeling

Abstract
Differences in ketosis and clinical mastitis rates, mean somatic cell counts (SCC) and reproductive performance scores (fertility status index = FS-index) between herds housed in free stall (n = 533) and tie stall (n = 59) barns were measured in relation to management and environmental factors in a retrospective cohort study of Norwegian dairy farms with automatic grain feeding systems. Herds with tie stalls were found to have a higher clinical mastitis rate, (61.6 cases per 100 cow-years versus 46.4 cases per 100 cow-years (p<0.01)); a significantly higher proportion of herds with ketosis, (relative risk = 1.59, (p<0.01)); and a lower mean fertility status index, (67.3 versus 82.8 (p<0.01)). No significant difference in mean SCC was found between the 2 groups of dairies (p = 0.32). Large herds had higher Loge geometric mean SCC than small herds (p<0.01) and herds with high SCC had lower milk production than herds with low SCC (p<0.01). Herds that scored “very good” on cow cleanliness had significantly lower adjusted mean SCC than herds with scores of “average” or “good” (p<0.05). Herds in barns with a concrete floor had an adjusted mean number of cases of clinical mastitis of 51.4 per 100 cow-years, 14 per cent higher than herds in barns with rubber mats, litter bed or wood (45.2 cases per 100 cow-years) (p<0.05). Herds with high milk production level had higher FS-index than herds with low milk production (p<0.01). Lower disease rates and the higher fertility status measured in the present study favor free stall herds over tie stall herds.
Sammendrag
Forskjeller i frekvensen av ketose og klinisk mastitt, gjennomsnittlig celletall og fruktbarhetsstatus (FS-tall) mellom løsdriftsbesetninger og båsbesetninger ble undersøkt i relasjon til ulike miljøfaktorer blant Norske storfebesetninger med automatisk kraftfórtildeling.
Båsbesetningene hadde mer klinisk mastitt, (gjennomsnittlig 61.6 tilfeller pr 100 årskyr versus 46.4 tilfeller pr 100 årskyr (p<0.01)), høyere andel av besetninger med ketose, (relativ risk = 1.59, (p<0.01)), og lavere FS-tall, (gjennomsnittlig 67.3 versus 82.8 (p<0.01)). Ingen signifikant forskjell i gjennomsnittlig celletall ble funnet mellom de 2 gruppene av storfebesetninger (p = 0.32).
Store besetninger hadde høyere Log{ine} av geometrisk middel celletall enn små besetninger (p<0.01), og besetninger med høyt celletall hadde lavere melke-produksjon enn besetninger med lavt celletall (p<0.01). Besetninger med “svært godt” reinhold av kyme hadde signifikant lavere gjennomsnittlig celletall enn besetninger som hadde “middels” eller “godt” reinhold av kyme (p<0.05). Besetninger i fjøs med betong-golv hadde gjennomsnittlig 51.4 tilfeller av klinisk mastitt pr 100 årskyr, 14% mer enn besetninger med gummimatte, strøseng eller tre (45.2 tilfeller pr 100 årskyr (p<0.05)). Besetninger med høy melkeproduksjon hadde høyere FS-tall enn besetninger med lav melkeproduksjon (p<0.01).
Den lavere sjukdomfrekvens og høyere fruktbathets-status målt i denne undersøkelsen favoriserer løsdriftsbesetninger framfor båsbesetninger.
