Our seasonal tank rental has proven an attractive option for the Beef or Goat breeder who does all AI in a seasonal window [spring—beef; fall—goats]. Your semen is stored here, a tank is delivered by the date you tell us AI needs to begin, the tank is picked up after your breeding window ends. Now we need more tanks that fit our service recharge window. So if you would like to trade up to a newer tank, your existing tank is worth more on a trade. If you store embryos, a newer tank has advantages to you.
