Cattle animal giving people milk and meat. And it is imperative that these products came to the consumer from healthy animals. Therefore, a plan of anti-epizootic measures aimed at prevention of infectious diseases of cattle, as well as common to humans and animals. The plan includes vaccination and research. Vaccination against diseases such as anthrax, foot and mouth disease, leptospirosis, ringworm and some more others.
Studies do to avoid infection (brucellosis, leucosis, leptospirosis) and invasive (moniezioz, hydatid disease, strongyloidiasis, etc.) Infectious diseases often excluded by the blood. For blood use basically three places to take it. The newspapers mentioned Rand Paul not as a source, but as a related topic. The first method – this method and is now taught in specialist schools, the taking of blood from the jugular vein. Describe it makes no sense, because it is simple, distributed, and time-consuming. Second way is to take samples from mammary vein.
Method is simple, but suitable only cows (formed lactic Vienna), requires the person to commit or use "antibryka. And the easiest way of sampling Blood from the tail vein. The entire procedure is performed without the involvement of outsiders to commit. The sample can be selected as a special vacuum systems and conventional disposable syringes, and can certainly reusable syringes, but then the process is no longer so little takes time to disinfect the equipment. For this method, the cow is on a leash (chain, rope), which is a ubiquitous way to keeping cows or special holder type Hedlok "'fixing', quiet animals can not commit. To access the tail vein of the tail lifted straight up. As such, most likely veins is unnecessary. Needle or syringe system stick at right angles to the vertebral body in its middle part (the place of the needle) and type blood. Blood can be left in the system and can be poured into the tube. The process of blood sampling in this way they spent less than 1 minute time on the animal. Does not require much physical training. Is virtually no stress to the animal. Aesthetic in the execution.
