Abstract

Large variations in the level of 5α-androstenone in fat from different boars have been found. No significant difference in the level of 5α-androstenone was detected in fat from boars selected for high rate of gain and low back fat (HP-line), low rate of gain and high degree of fatness (LP-line) and a control group maintained without deliberate selection (GL-line). In boars used in artificial insemination service relatively high levels of 5α-androstenone in fat were observed, and in these animals a significant (P < 0.05) positive regression of 5α-androstenone level on age was found. Positive but non-significant regression coefficients were found between number of services which the boars had performed and level of 5α-androstenone in fat from the same animals.

Sammendrag

Det ble funnet store variasjoner i 5α-androstenonkonsentrasjonen i fett fra forskjellige råner. Det ble ikke påvist signifikante forskjeller i 5α-androstenonnivå i fett fra råner selektert for høy veksthastighet og tynt ryggspekk, lav veksthastighet og tykt ryggspekk og en kontrollgruppe. I fett fra råner brukt i kunstig Sædoverføring, fant en relativt høye konsentrasjoner av 5α-androstenon og hos disse fant en signifikant (P < 0,05) positiv regressjon av 5α-androstenonnivå på alder. Positive, men ikke signifikante regressjonskoeffisienter ble funnet mellom antall parringer rånene var benyttet til og nivå av 5α-androstenon i fett fra de samme dyr.
