A listing page and contacting the seller
Click a card to open it. You will see the photos (click through them if there are several), the hashtags, Description, EPDs and Seller. To ask about it:
- In the Contact Seller box, fill in your name, email, phone (optional) and a message.
- Click Send Inquiry. You will see “Inquiry sent”. The seller gets it under their inquiries and by email.
Packages: order a mating program
A package is a mating program from one ranch. You pick a sire and a dam from the ranch’s animals, then choose how it arrives: straws, embryos, a confirmed pregnancy or a live calf.
On the Packages page, search with Search programs or ranches…, filter by Delivery (Straws, Embryos, Pregnancies, Live Calves), Ranch (Find a ranch…) and Price range, and sort by Sort: Featured, Sort: Newest or price. A package page lists the Sires and Dams (each with Inspect), About this program and Order this program.
- Under Order this program, click a delivery option. “Quote” means the ranch will price it for you.
- Click Build a Calf. Choose the sire, then the dam, then how the mating should arrive.
- Your choice goes into Your Cart. Click Checkout, then Submit Order.
No payment is taken online. The ranch sends you the invoice and payment details directly. Ask a Question takes you to the ranch’s page to message them first.
