Fewer but better bulls

The later years great changes in the breeding work have had significant impact on the keeping of bulls in VikingGenetics with fewer bulls, more sires of sons and higher genetic progress.

A sustainable breeding scheme has focus on variation in the genetics. It is the variation that in the long run will ensure that we maintain the high genetic development. In VikingGenetics we focus on this. Table 1 and 2 are based on sires born in 2013 and 2014, bought by VikingGenetics and used for insemina-tion. In total there are 273 VikingHolstein sires; 147 born in 2013 and 126 in 2014.

The 273 VikingHolstein sires have
110 different sires corresponding to 2.5 sons in average per sire
o Including 43 foreign sires and 67 Viking sires
89 different maternal grandsires

Annual progress of 5.6 NTM units!
Table 1 shows the average genetic level for the sires per birth year. As the figures show there is pro-gress for all traits (>100). It is also clear that for production, udder health, udder and longevity the sires are superior to the cows (figures in the 2014 column are highest). The high average NTM of +27.0 and +32.6 show impressive progress of 5.6 NTM units from 2013 to 2014.

Table 2 shows that 196 sires were born in Denmark, 39 in Finland and 38 in Sweden. This reflects very well the distribution of the Holstein cows in the countries with a small majority of cows in Denmark due to the higher activity of ET in Denmark.

VH Loop (D Limbo) is one of the fine genomic sires.
