Artificial Insemination Basics

I am often asked questions about how this all works.  Here is some of the basic information you need to know before getting started with AI.

Ordering Straws:  Most people want to order at least 2 straws per cow, in case a cow doesn’t settle on the first try.  Extras can be kept in storage for use at a later date.  I do not have a minimum order, but shipping is expensive so it’s better to buy more for one shipment than to have to buy & ship more a second time.  I’ll need to know how many straws you want from what bull, as well as your name & phone number.

Shipping & Storage:  Straws are shipped frozen, in a nitrogen tank, from the collection facility.  You will need to have them shipped to your AI tech or vet who will be doing AI for you, so they can store the straws in their own nitrogen tank until your cow is ready to breed.  Have this person’s shipping address & phone number available when you arrange shipping with the collection facility.

Payment:  You will need to pay me for the straws you are ordering.  Once I receive payment, I will release the straws to you with the collection facility.  Then you will need to contact the facility to arrange & pay for the shipping, which can be done with a credit card over the phone.

Breeding Your Cow:  You will have to be able to tell when your cow is in standing heat & ready to breed.  AI is usually done 12 hours after the beginning of standing heat.  If you have more than one bovine, you can use a heat detection patch, like Estrotect stickers, to determine when your cow is standing to be mounted.  If you only have one cow & can’t tell when she is in heat, then you may have to talk to your vet or AI tech about doing a synch protocol with hormone injections.

Sexed Semen Straws: When using sexed semen, there are some important differences to keep in mind. Because of the extra process of sorting the semen, straws need to be handled with extra care. Timing of breeding is 18 hours after onset of standing heat instead of the normal 12 for conventional straws. It is also recommended that you do NOT use a synch protocol when breeding with sexed semen. Make sure to tell your vet or AI tech that you will be using sexed straws when you arrange for breeding your cow so they can plan accordingly.
