When you squeeze a horses teats clear liquid comes out?

When you squeeze a horse's teats and clear liquid comes out, it is likely colostrum or milk, especially if the mare has recently given birth. This clear fluid can be a sign of early lactation or preparation for nursing. It's important to handle horses gently and with care, as this can be uncomfortable for them. If you have concerns about a mare's milk or health, consulting a veterinarian is advisable.
