Unbelievable Information About Cow

Cattle were originally identified as three separate species: Bos taurus, Bos indicus,te zebu;
and the extinct bos primigenius,the aurochs.Now these have been reclassified as one species,Bos taurus,with three subspecies;Bos taurus primigenius,and Bos taurus taurus.
Cattle can only be used in the plural and not in the singular.
In laboratory studies, young cattle are able to memorize the locations of several food sources and retain this memory for at least 8 hours,
although this declined after 12 hours. Cattle tested in a radial arm maze are able to remember the locations of high-quality food for at least 30 days.
In cattle,temperament can affect production traits such as carcass and meat quality or milk yield as well as affecting the animal’s overall health and reproduction.
Cattle use all of the five widely recognized sensory modalities. These can assist in some complex behavioral patterns, for example, in grazing behavior. Cattle eat mixed diets, 
but when given the opportunity, show a partial preference of approximately 70% clover and 30% grass. This preference has a diurnal pattern, 
with a stronger preference for clover in the morning, and the proportion of grass increasing towards the evening.Vision is the dominant sense in cattle and they 
obtain almost 50% of their information visually.
Cattle are a prey animal and to assist predator detection,their eyes are located on the sides of their head rather than the front.This gives them a wide field of view of 330o but limits binocular vision (and therefore stereo-psis) to 30o to 50o compared to 140o in humans.
This means they have a blind spot directly behind them.Cattle have good visual acuity but compared to humans, the visual accommodation of cattle is poor.
Cattle have a well-developed sense of taste and can distinguish the four primary tastes (sweet, salty, bitter and sour). 
They possess around 20,000 taste buds. The strength of taste perception depends on the individual’s current food requirements. They avoid bitter-tasting foods (potentially toxic) and have a marked preference for sweet (high calorific value) and salty foods.http://www.godhan.in/news/
