Clostridium tetani is a common soil bacterium and the causative agent of tetanus.Vegetative cells of Clostridium tetani are usually rod-shaped and up to 2.5 μm long, but they become enlarged and tennis racket- or drumstick-shaped when forming spores.
Grass tetany also called the staggers , is a metabolic disease involving magnesium deficiency, which can occur in such ruminant livestock as beef cattle, dairy cattle and sheep, [1] usually after grazing on pastures of rapidly growing grass, especially in early spring. Despite the name, it is unrelated to tetanus.
Subsistence farming is being superseded by intensive animal farming in the more developed parts of the world, where, for example, beef cattle are kept in high-density feedlots, and thousands of chickens may be raised in broiler houses or batteries. On poorer soil, such as in uplands, animals are often kept more extensively and may be allowed to ...
In older English sources such as the King James Version of the Bible, cattle refers to livestock, as opposed to deer which refers to wildlife. Wild cattle may refer to feral cattle or to undomesticated species of the genus Bos. When used without a qualifier, the modern meaning of cattle is usually restricted to domesticated bovines. [15]
BSE is a degenerative infection of the central nervous system in cattle. It is a fatal disease, similar to scrapie in sheep and goats, caused by a prion.A major epizootic affected the UK, and to a lesser extent a number of other countries, between 1986 and the 2000s, infecting more than 190,000 animals, not counting those that remained undiagnosed.
Extensive farming can have the following problems: [3] Yields tend to be much lower than with intensive farming in the short term. Large land requirements limit the habitat of wild species (in some cases, even very low stocking rates can be dangerous), as is the case with intensive farming. Less profitable then intensive farming per unit of area.
Transport tetany is a disease that occurs in cows and ewes after the stress of prolonged transport in crowded, hot and poorly ventilated vehicles. It is commonly seen in animals in late pregnancy and those transported to slaughter. The disease is generally fatal, even with treatment, unless detected early.
Impacts of heat stress on livestock animals. [2]Once the body temperature of livestock animals is 3–4 °C (5.4–7.2 °F) above normal, this soon leads to "heat stroke, heat exhaustion, heat syncope, heat cramps, and ultimately organ dysfunction".
