•  Payback = 3.5:1 (£49/cow)

What about the other benefits?

•  90% heifer calves gives you more easy calvings •  A Genus ABS trial across 8200 calvings showed

•  When a cow/heifer has a heifer calf •  Reduced rate of still birth calvings by 50% •  Decrease in days open by 12 days (worth £60/

cow) Cheshire Dairy Farmer milking 800 cows “When using sexed semen, for me the Heifer calf is a bonus...” Why? CALVING EASE

1st  Time  buyers  

• Try  20  doses  in  their  heifers  

2nd  year  • Used  sexed  in  all  their  maiden  heifers  

3rd  year  

• Generate  all  required  replacements  using  sexed  semen  

• BEEF  semen  usage  goes  up  significantly  

• DAIRY  semen  usage  goes  down

Conclusions

•  Sexed semen works and is profitable for Dairy Farmers, if used correctly

•  Huge welfare benefits through easier calvings and fewer Holstein bull calves

•  Future growth slowing because 1) Product expensive to produce and hence buy 2) Decline in conception rates make maiden heifers

the only viable market for most farmers 3) The Elite bulls generally not available
