Chin-ball mating harness

Description

A halter that fits under the bull's chin and marks the cows he mounts, so you can see which cows have been served and which are bulling for AI. It suits working bulls and vasectomised teaser bulls.

The stainless steel, cone-shaped marker has a ball that turns freely and works like a ballpoint pen. When the bull mounts and slides off, it leaves a streak along her back. Ignore single streaks, which usually come from cattle brushing past each other; marks from a mount run along the backbone. Marks last about 4 to 14 days, depending on the colour.

One fill of the reservoir marks about 25 to 30 cows. Fill it with marking fluid and check the ball turns. Fit the halter with the neck strap first, then the nose strap, so the marker sits snug under the chin without stopping the bull's jaw moving. Use one harness per bull, and keep harnessed bulls apart from the cows when you're bringing them in, to cut down on stray marks.

At the end of the season, clean out the leftover fluid with a solvent, fill the tank with oil, and clean the halter. The fluid is sold separately.
