This is where late pregnancy fetal surveillance comes in handy. The non-stress test is one of the staples. Why Do an NST. This test can be done in the later stages of pregnancy. It is more frequently used in cases where the mother is going past her assigned due date to ensure fetal well-being.
Not sure what it's called, but we make the same knot that the baler knotter makes to tie balls together. Hold the 2 twines together, make a loop, and pass the ends through the loop, trim to about 1 inch. If you cut the ends too short (makes no difference in the knot) the twine will simply pull apart.
If you are tying just one horse, you can tie a small loop knot in the center of the rope, or you can tie two knots, with each one at least 6 feet from your end post, and secure your horse between the two knots. You will then attach a carabiner or swivel hook to the rope or loop.
