The Chin-Ball Mating Harness was developed in New Zealand, and is used around the world for identifying mated cows. The robust harness/halter has a cone-shaped device underneath which contains a freely-rotating ball, working on the same principle as a ball-pen. The stainless-steel container can be filled with ink of the desired colour. Each fill is enough to mark 25-30 cows (approx. 0.5 litre). When a cow is properly in season she will receive very clearly identifiable back markings from the bull (or cow) wearing the device. Marks fade in 4 to 14 days. We suggest changing colours on a 3 week cycle, to prevent any confusion. Ink is available in 1 litre containers. Ink is oil based. NB: Ink must be mixed thoroughly if it has been stored for some time.
Handyscope is a high-powered portable microscope especially made for fast and reliable fertility testing of semen. The device is ideal for ensuring semen selected for breeding is of the highest quality. Handyscope is powered by a replaceable camera-type lithium battery that will give around 10 hours of operation (battery included and spare supplied). The high-intensity LED lamp gives clear, bright images, even in dark working conditions. Magnification is 200X, equivalent to a good desktop unit. A fine-focus adjustment is incorporated. The Handyscope can be used with regular glass slides, but 5 special polycarbonate slides are supplied with the unit. These slides reduce cold-shock to the semen sample, giving more accurate motility results. They also have greater safety, being unbreakable, and can be reused. 100 slide cover slips are also supplied.
