| description | Enrichment for laboratory animals is widely discussed and it is getting more commonly known as something that can help with increasing the animal welfare. However, more studies are needed in how enrichment is used and how it affects animal behaviour.
Seventeen male rats of the strain Lewis were given three different types of temporary enrichment types; cardboard, paper and fabric. The rats were filmed during three weeks and their behaviours were analysed. An ethogram was used to determine if there was a difference regarding interaction with enrichment types, activity levels and negative behaviours.
The rats interacted with the temporary enrichment differently during the two weeks when temporary enrichment was offered, compared to the first control week where no extra enrichment was given. During the first week with temporary enrichment the rats interacted the most with cardboard, but during the second week they interacted the most with the fabric. Resting behaviours where the highest during the week where the animals did not have access to extra enrichment. Active behaviours where the highest during the first week with extra enrichment, and the lowest the second week with enrichment.
When the rats did not have access to temporary enrichment they had more negative social behaviours than positive social behaviour. When the temporary enrichment was introduced the positive social behaviours increased whereas the negative social behaviours decreased during both weeks.
Enrichment should be used in a laboratory setting to increase the animal welfare. It is important that different types of enrichment is being offered to increase the opportunity of performing a more broad spectra of natural behaviours in the rats. |

Berikning för försöksdjur är ett allmänt diskussionsämne och det blir allt vanligare att det ses som ett verktyg för att öka djurens välfärd. Det behövs dock fler studier kring hur berikning används och hur det kan påverka djurens beteende. Sjutton hanråttor av stammen Lewis fick tre olika typer av temporära berikningar; kartong, papper och tyg. Råttorna filmades under tre veckor och deras beteenden analyserades. Ett etogram användes för att avgöra om det fanns skillnad vad gäller interaktion med berikningstyperna, aktivitetsnivåer och negativt beteende. Råttorna interagerade annorlunda med den tillfälliga berikningen under de två veckorna då den erbjöds, jämfört med den första kontrollveckan där ingen extra berikning gavs. Under den första veckan med tillfällig berikning interagerade råttorna mest med kartong, men under den andra veckan interagerade de mest med tyget. Andelen beteenden som räknades som ej aktiva var högst under veckan där djuren inte hade tillgång till extra berikning. Andelen aktiva beteenden var högst under den första veckan med extra berikning och lägst den andra veckan med extra berikning. När råttorna inte hade tillgång till tillfällig berikning hade de mer negativa sociala beteenden än positiva sociala beteenden. När den tillfälliga berikningen infördes ökade de positiva sociala beteendena medan de negativa sociala beteendena minskade under båda veckorna. Berikning bör därför användas i laboratoriemiljöer för att öka djurens välbefinnande. Det är viktigt att olika typer av berikning erbjuds för att öka möjligheten att utföra ett bredare spektrum av naturligt beteende hos råttorna. 2021-06-22 First cycle, G2E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/16865/1/Nordqvist_K_210611.pdf Nordqvist, Kate, 2021.
