Cows are the largest domestic animals. The most common species of this sort (large horns ).They are raised for meat, milk and other dairy products, but also used for work : pulling carts, plows ,etc. In India cows are sacred. There are around 1.3 billion cattle worldwide.
The cow’s stomach has four compartments: the rumen, reticulum, omasum and abomasum.This embodiment is adapted to a vegetal diet, grazed and swallowed quickly. The rumen, bulky, has a capacity of about 20 liters, and stores grass. The reticulum and omasum have wrinkled walls and in the abomasum the digestive juice is produced.
Its body is covered with short hair, color varies by race. The head has a long snout with wet lips. On them the nostrils are found. The cow has mobile ears and big eye . From the neck hangs a fold of skin called dewlap. The cow’s horns are hollow. The voluminous trunk ends in a long tail, with bristles on the end. On the ventral side there is an udder with four teats. Each leg ends with a hoof. The mandible has six incisors, broad, sharp, pointing obliquely forward, on the jaw they are missing, the front of it being covered by a horny blade. Next to it an empty space where the canines are missing. The molars have on their surface enamel crests, crescent-shaped. The male is called a bull and is slightly larger than the cow. The biggest bull weighed in 1910 had over 2 tons.
When the cow feeds it grabs the grass with its lips, holds the grass with its tongue in a bundle and severs it with the incisors, which rest on the horny blade. The grass is gathered in the rumen. When it fills up, the cow finds a place to rest and begins to chew; it is a ruminant herbivore. The grass goes from the rumen to the reticulum and then to the mouth. The chewing is done by moving the jaw from left to right. Soaked with saliva the chewed grass goes this time in the omasum and then in the abomasum where digestion continues,ending in the small intestine
The gestation period is 9 months. A calf at birth weighs between 25 and 45 kg. Once a year the cow gives birth to a single calf, which is fed with the milk produced by the udder.
Did you know that:
A cow grazes around 8 hours a day, the same time it ruminates on the swallowed food.
The average life expectancy is 25 years. The oldest cow in the world was Big Bertha, she lived for 48 years and gave birth to 23 calves. She died in 1993.
The old cows in India (the country where these animals are sacred) are accommodated in special hostels. Over a lifetime, a cow can produce milk for 200,000 glasses.
When grazing, cows don’t tear the grass only with the teeth but also use their hard tongue.
A 700kg cow needs 28kg of grass and hay a day!
No, the powder milk is not produced when you throw a cow off a plane!
The only place on a cow’s body where there are sweat glands is its nose.
