bull
s research shows that the level of
sole
ulcer differs a lot from farm to farm. for example, in the united kingdom, cases of
sole
ulcer affect approximately six dairy cows per 100 annually, but the range on uk farms is wide: 0-54.8 cases per 100 cows per year. the improvement in hoof health is directly re- flected on the level of costs for the farm. one severe case of
sole
ulcer in the nordic countries is estimat- ed to cost 1,300 euro. assuming that the current level of
sole
ulcer on the farm is equal to the popu- lation average. we can calculate how much the farmer can save by using the
bull
that is superior in hoof health. that means that a herd with 500 cows that has 50 cows (10% of cows) with severe cases of
sole
ul- cer can save about 40,000 euro per year, by using a
bull
with
ebv
120 for
sole
ulcer, while a herd with 500 cows and 150 cows (30%) of severe
sole
ulcer cases can save around 120,000 euro. for the other six hoof disorders (digital dermatitis, in- terdigital dermatitis,
sole
hemorrhage, heel horn erosion, double
sole
, white line disease), a
bull
with
ebv
120 will decrease cases of disease by 16-24% compared to the
bull
with
ebv
100. while a
bull
with
ebv
120 has a positive influence on the level of hoof health by decreasing the disease and the costs related to those, a
bull
with
ebv
80 will actually in- crease the disease and cause the decline in the genetic level of hoof health. it is important to keep in mind that there is a differ- ence between
bull
s and thereby selecting the right genet- ics is crucial to ensure the high genetic level for hoof health in your herd. by relying on ntm in your breeding goal, you are always breeding for improved profit. hoof disorders
