Résumé : |
Our work on the vertical fibre hide condition in Hereford cattle (1,2) has indicated that this condition is not controlled by genes at a number of separately segregating loci but is due to the presence, in a homozygous state, of either an autosomal recessive gene or a number of genes at tightly linked loci. As a result of this finding, we have examined the effect of various breeding programs on the frequency of the vertical fibre hide condition in a herd over a period of ten generations to determine if this is a practical method of reducing the incidence of the condition.
The selection programms considered for this purpose were:
1) the removal of all affected animals from the herd,
2) the removal of all affected sires only,
3) the use of known homozygous normal sires.
In the work described below, animals which show the condition, determined using techniques described previously (3), are considered to be homozygous, while those which are not affected are either heterozygous (carriers) or are homozygous normal (i.e having one or no gene for vertical fibre, respectively). |
