Mature horses appear to develop a certain degree of resistance to this parasite, but it is a concern for younger horses up to about two years old. [4] P. equorum is one of the few parasites where a natural immunity develops in the host. [3] However, when an infection is found in an adult horse, both the worm and egg counts are substantially low ...
Though they need a great deal of water, horses spend very little time drinking; usually 1–8 minutes a day, spread out in 2-8 episodes. [14] Water plays an important part in digestion. The forages and grains horses eat are mixed with saliva in the mouth to make a moist bolus that can be easily swallowed.
An ordinary 30 μm thin section is prepared as described above but the slice of rock is attached to the glass slide using a soluble cement such as Canada balsam (soluble in ethanol) to allow both sides to be worked on. The section is then polished on both sides using a fine diamond paste until it has a thickness in the range of 2–12 μm.
This means that horses have only one stomach, as do humans. However, unlike humans, they also have to digest plant fiber (largely cellulose ) that comes from grass and hay . Therefore, unlike ruminants , who digest fiber in plant matter by use of a multichambered stomach , horses use microbial fermentation in a part of the digestive system ...
Ultramicrotomy is a method for cutting specimens into extremely thin slices, called ultra-thin sections, that can be studied and documented at different magnifications in a transmission electron microscope (TEM). It is used mostly for biological specimens, but sections of plastics and soft metals can also be prepared.
Microtechnique is an aggregate of methods used to prepare micro-objects for studying. [1] It is currently being employed in many fields in life science. Two well-known branches of microtechnique are botanical (plant) microtechnique and zoological (animal) microtechnique.
Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures. [3] The risk of animals becoming ill during the fall is increased, as many plants slow their growth in preparation for winter, and equines begin to browse on the remaining plants.
Horses require access to clean fresh water at all times, and access to adequate forage such as grass or hay. Unless an animal can be fully maintained on pasture with a natural open water source, horses must be fed daily. As horses evolved as continuous grazers, it is better to feed small amounts of feed throughout the day than to feed a large ...
