Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Another medication that is used to manage cow heat is gonadotropin-releasing hormone (GnRH). This hormone is responsible for stimulating the release of other hormones that are essential for a cow's reproductive cycle. GnRH can help synchronize heat cycles in a group of cows, making it easier for farmers to plan and manage breeding schedules.

Selenium, a trace mineral, works synergistically with Vitamin E to enhance its antioxidant properties. It is essential for the proper functioning of enzymes that protect cells from oxidative damage. In cattle, selenium deficiency is linked to white muscle disease, a serious condition that affects the heart and skeletal muscles. Symptoms of this disease can include reluctance to move, muscle stiffness, and in severe cases, sudden death. Ensuring that cattle receive adequate selenium is vital for preventing such conditions and ensuring the overall health of the herd.
