ABSTRACT


The present survey
is based on the investigation of 397 purebred Arabian mares used for breeding
in the period of 1970 – 1996, which came from the primary broodmare
band in the Białka, Janów Podlaski, Kurozwęki and Michałów Stud Farms. Mares
that had been used for 5 and more breeding seasons were selected from the total
number of animals. For such mares, their oestrus periods were investigated in
the breeding documentation.

On the basis of our investigation the following regularities can be observed:


  • the differences in average sexual cycles, periods of anoestrus and the oestrus length
    between the various stud farms were significant or highly significant, which
    can attributed to the differences in breeding environments of those stud farms;


  • the
    length of the complete sexual cycle, oestrus, and anoestrus was characterised
    by a low or negative correlation to the racing performance of both the mares
    under investigation, as well as their progeny;


  • in
    the population of purebred Arabian horses farmed in Poland one can distinguish
    genetic lineages that vary significantly as to their length of oestrus periods;


  • characteristic
    differences were observed in the average length of the oestrus cycle, the oestrus
    itself, and the periods of anoestrus in specific coefficient of success ranges.



Key words: Arabian mares, racing performance, sexual cycle.
