Frequencies of Alleles of the B-Blood Group System in Red Danish Dairy Cattle

Allele Frequenzen im B-System der Roten dänischen Milchrasse

Allele frekvenser i B-systemet hos RDM

Summary

The frequencies of B-alleles in RDM were analysed in samples of 637 bulls born in 1963–64–65, 794 bulls born in 1960–61–62 and 1226 cows from common herds.

Among the 46 distinct alleles for which frequencies were estimated only about 10 alleles have frequencies above 1 %. The frequency of some alleles shows consistent variations during the last 10–15 years.

The degree of homozygosity at the B-locus has remained almost constant among bulls during the last 10–15 years, while the homozygosity among cows from common herds shows a decreasing tendency.

Zusammenfassung

Die Häufigkeit der Allele im B-System beim Roten dänischen Milchvieh ist anhand einer Analyse von 637 Stieren geboren in den Jahren 1963–64–65, 794 Stieren geboren in den Jahren 1960–61–62 und 1226 Kühen, die in den Jahren 1963–64–65 typenbestimmt worden sind, untersucht worden. Nur etwa 10 von den insgesamt etwa 46 Allelen besitzen eine Häufigkeit von mehr als 1 %. Einzelne von diesen zeigen systematische Verschiebungen in der Häufigkeit im Laufe der letzten 10 bis 15 Jahren. Eine Untersuchung über den Homozygotiegrad im B-System zeigt, dass dieser in den vergangenen 10 bis 15 Jahren bei den Stieren recht konstant gewesen ist. Dagegen zeigt die Homozygotie bei Kühen in gewöhnlichen Viehbeständen eine fallende Tendenz.

Sammendrag

Hyppigheden af allelerne i B-systemet hos RDM er belyst ved en analyse af 637 tyre født i årene 1963–64–65, 794 tyre født 1960–61—62 og 1226 køer typebestemt i 1963–64–65. Kun en halv snes af de ialt ca. 46 alleler har hyppigheder over 1 %. Enkelte af disse viser systematiske forskydninger i hyppighed gennem de sidste 10–15 år. En undersøgelse over graden af homozygoti i B-systemet viser, at denne har været ret konstant hos tyrene i de sidste 10–15 år, medens homozygotien hos køer fra almindelige brugsbesætninger viser en nedadgående tendens.
