Abstract

The influence of environment on animal health was studied in 40 bacon herds. These herds delivered approx. 11,000 baconers annually to the slaughter-house. The data from the meat inspection was studied in connection with the environmental recordings, and the relationship between 18 lesions and 20 environmental factors were estimated by statistical methods. The data was collected in the period 1975–1977.

The influence of environmental factors upon the prevalence of different lesions showed considerable variation. Ten environmental factors were significantly associated with pleurisy and tail lesions (cannibalism). On the other hand none of the environmental factors bore any significant relation to atrophic rhinitis, pericarditis, peritonitis, perihepatitis, polyarthritis, arthritis and claw lesions. Eight environmental factors influenced the proportion of healthy animals.

The recorded environmental factors influenced the overall health situation to a varying degree. For example, design of pen walls, insulation of pen floors, occasional use of supplementary feed and free access to drinking water were related to 5–7 lesions, while the nature of the concentrate (meal/pellets) had no significant influence.

The study indicated that many details in environment and management could be of importance to the health of bacon pigs. However, statistical analysis also showed that production systems had a considerably stronger influence upon the health situation than any of the “pure” environmental factors – even when these factors were added.

Sammendrag

I 40 svinebesetninger med en årlig leveranse på ca. 11.000 slakt har en studert samspillet mellom miljø og helsetilstand. Som uttrykk for heLsetilstanden ble brukt registre ringe ne utført av kjøttk on trollen ved slakteriel. Dataene fra slakteriet ble koblet sammen med müjøregistreringene og sammenhengen mellom 18 ulike patologiske funn og 20 miljøfaktorer ble vurdert v. h. a. statistiske metoder. Dataene ble samlet inn i årene 1975–1977. Tre ulike produksjonssysterner (kombinert, alt inn/alt ut, kontinuerlig) og besetningsstørrelser inngår i materialet.

Undersøkelsen viste en betydelig variasjon i miljømessig innflytelse på utviklingen av de ulike sjukdomer. Atrofisk rhinitt, pericarditt, perihepatitt, peritonitt, polyartritt, artritt og klauskader var ikke relatert til noen av de behandlede miljøfaktorer, mens pleuritt og halesår (kannibalisme) viste sammenheng med 10 og „friske” dyr med 8 faktorer.

Det var også stor forskjell på utslaget av de forskjellige miljøfaktorene. Utforming av bingeskiller, isolasjon av gulv, tilfeldig bruk av tilleggsfôr (grovfôr) og fri tilgang på drikkevann så ut til å influere på 5–7 ulike sjukelige tilstander, mens kraftfôrstrukturen (mjøl/pellets) viste ingen relasjoner til patologiske funn.

Undersøkelsen indikerte at mange detaljer angående miljøet kan ha betydning for grisens helse. Men den statistiske analyse viste at produksjonssystemet hadde en betydelig sterkere innflytelse på helsesituasjonen enn noen av de „reine” miljøfaktorene — også sterkere enn disse faktorer sammenlagt.
