Abstract

A method for breeding, especially a method for breeding dairy cattle without use of heat detection prior to insemination.

Claims

1. A method for breeding dairy cattle, the method comprising the steps of:

inseminating a cow;

administering progesterone nineteen days after insemination;

performing ultrasound on the cow twenty six days after insemination;

and determining whether the cow is open.

2. The method of claim 1, further comprising the step of administering progesterone to the cow nine days before insemination.

3. The method of claim 2, wherein the progesterone is administered by application of a vaginal insert.

4. The method of claim 3, wherein the first progesterone insert is removed two days before insemination.

5. The method of claim 4, further comprising the step of administering gonadotropin releasing hormone to the cow nine days before insemination.

6. The method of claim 5, further comprising the step of administering prostaglandin F2α

or cloprostentol to the cow two days before insemination.

7. The method of claim 1, wherein the steps are repeated at least once if the cow is open.

8. A method for breeding dairy cattle, the method comprising the steps of:

administering a first progesterone dose to a cow;

inseminating the cow nine days after administration of the first progesterone dose;

obtaining a biological specimen from the cow at least seven and less than thirteen days after insemination;

performing at least one assay the biological sample; and

determining whether the cow is open based on the result from the assay.

9. The method of claim 8, further comprising the steps of:

administering a second progesterone dose twelve days after insemination to a cow that is determined to be open; and

inseminating the cow nine days after the second progesterone dose.

10. The method of claim 8, wherein the first progesterone dose is administered by application of a vaginal insert.

11. The method of claim 10, wherein the insert is removed two days before insemination.

12. The method of claim 8, further comprising the step of administering further comprising the step of administering gonadotropin releasing hormone to the cow nine days before insemination.

13. The method of claim 8, further comprising the step of administering prostaglandin F2α

or cloprostentol to the cow two days before insemination.

14. A method for breeding dairy cattle, the method comprising the steps of:

administering a first progesterone to a cow;

administering a first gonadotropin releasing hormone dose to the cow on the same day;

administering a second gonadotropin releasing hormone dose to the cow nine days after

administration of the first gonadotropin releasing hormone dose;

implanting an embryo into the cow seven days after the second gonadotropin releasing hormone dose; and

administering a second progesterone dose to the cow twenty eight days after the first progesterone dose.

15. The method of claim 14, further comprising the steps of:

performing ultrasound on the cow thirty five days after the first progesterone dose;

and determining whether the cow is open.

16. The method of claim 15, further comprising implanting an embryo into the open cow forty two days after the first progesterone dose.

17. The method of claim 14, wherein the first and second progesterone doses are administered using a vaginal insert.

18. The method of claim 17, further comprising the steps of removing a vaginal insert used to administer the first and second doses seven days after administration of the vaginal insert.

19. The method of claim 14, further comprising the step of administering prostaglandin F2α

or cloprostentol to the cow seven days after the first progesterone dose.
