Freemartin Probe

Description

• This Freemartin Probe is a newly developed vaginal probe to detect freemartin heifers and/or determine if heifers born co-twin to a bull have a normal reproductive tract.
• The crucial probe end length is 7cm.
• Research has shown that no freemartin calf has a vaginal length longer than 7cm.
• The distal end of the narrower center section is 14cm from the tip.
• Over 95 percent of heifers born co-twin to a bull and with a normal reproduction tract have a vaginal length of 14cm or more.
• Animals with a vaginal length of 7-14cm should have chromosome testing done to confirm if a freemartin.
• This probe is designed to be used on heifers 30 days or less of age.
