Can cows swim
Most cow breeders ask if it is :
can cows swim or not ?
The answer is yes. Most mammals are able to swim, including water- hating cats and desert camels. Although all animals evolved mainly from aquatic organisms, some of them retained their ability to swim, while others developed this ability after losing it.Read : Can pets catch the coronavirus ?
The body movements required for swimming are not much different from those necessary for walking, which explains why many types of mammals are able to swim. And cows contain sufficient amounts of fat in their bodies to keep them afloat.
Cows are considered to be animals that belong to the mammalian family, and ruminants, meaning that they re-chew food for digestion after swallowing, where they store it in their four-part stomach, then re-chew, and female cows are called the cow, while the male is called a bull, and the little one is called a calf, They are distinguished by their large horns and huge hooves, and people benefit from cows in many works, including plowing the land and rotating the mill, as well as using their milk, meat, and skins. They are considered among the least intelligent animals. Cows are raised in the plains and green pastures, and are usually raised. Around the world, in cold regions like Iceland, and hot as India.
And therefore cows like other animals that can swim.
How can cows swim ?
Movement and mobility
The ability to move is one of the defining characteristics of living things. They move on their own, and in this way they differ from inanimate objects that do not move unless they are pulled or pushed by an external force, and the movement of plants differs from the movement of animals. Able to move without being able to move from one place to another, and movement in plants is slow and unclear, examples of which are the growth of leaves towards the light, and the growth of roots down towards the soil, while animals often have organs that help them To move and change their position, such as: legs, wings, or fins.
Transport of animals
The ability to move and move is one of the basic needs of animals . They move from one place to another in search of food and shelter, and to escape from predators, and the animals are able to move thanks to the coordination between the muscular and nervous systems and the synergy between them. The nervous system controls the contraction of the body's muscles in terms of amount, type, and position, and thanks to this coordination, the animal can move its limbs or its entire body. The method of movement varies according to the environment in which the animal lives; There are animals that move in the water , others in the air, and others on the ground, or on trees.
Move around in the water
Many animals live in the water, there are marine mammals , such as: whales , fish of all kinds, and invertebrate animals, and the methods of transporting these animals differ from one species to another, and below is some information about the ways of transporting some types of animals in the water:
Some animals, such as jellyfish, move from one place to another in the water without the need to use the limbs and muscles, but let the water take them during their movement, and this method is described as a passive movement; The animal does not expend any kind of energy to be able to move.
Shrimp (shrimp) move from one place to another using small appendages called swimmers' legs. Marine mammals move in water differently from fish. They move their body as do land mammals even though they live in water, where dolphins and whales, for example , move their tails up and down. To be able to swim in the water, which is different from fish that move their tails left and right, while gray seals use their back fins to push their bodies in the water, and they use the front fins to direct their movement.
Freshwater mammals, such as otters and beavers, are able to move in the water thanks to the membranes between their toes, and their tail helps swimming as well.
Fish can swim in the water smoothly thanks to its streamlined body, and thanks to its caudal, pelvic and pectoral fins, and the body of the fish contains a floating bladder, which by controlling the volume of air inside it can float up or dive down.
Frogs are able to swim in the water by spreading their hind legs apart and pushing them into the water, while water comets swim by moving their bodies in a wave movement.
Water beetles are able to move around in the water thanks to the rows of bristles that cover their hind legs, acting like a paddle.
Water bugs are able to move on the surface of the water thanks to the air that permeates the filaments that densely cover their legs, keeping their legs dry.
Many microscopic plankton are able to move in the water using cilia, capillaries, or appendages that cover their bodies, and these appendages include antennae.
Move around in the air
Some types of animals are able to fly and move in the air easily thanks to their front limbs that have mutated into wings, including birds and bats, and the bodies of these animals have adapted to be able to fly successfully; She has lightweight bones, a large heart, large and strong chest muscles, and her sense of vision is sharp. Some animals are able to move through the air even though they do not have wings, and their movement is described as a kind of sliding and not a real flight like that done by birds, bats , and insects. Examples of this type of movement are :
Some types of fish move in the air; Thanks to their wing-shaped fins.
Some species of lizards and frogs (Rhacophorus) are able to slip through the air. Because there are membranes between her toes.
Some types of lizards and snakes are able to slip through the air. Thanks to the inflatable ribs in the presence of air.
Some animals, such as: flying marsupials, cologos, and flying squirrels, have folds of extra skin between the front ends and the back ends, enabling them to slide from tree to tree.
Traveling on land
Many animals live on land. Some of them have limbs that help them to walk, run, and jump, and some of them have no limbs, crawling on the ground, and here are some examples of ways of transporting animals on land:
Crawling: Many organisms move by crawling, including: The white-tipped snail uses the muscle foot as a crawling organ, and as it walks it secretes a sticky salivary substance that leaves a trail behind it. Snakes crawl on the ground with the help of scales that cover their body, and thanks to their strong muscles, snakes usually crawl in a undulating movement. It is pushed sideways and forward in the form of the letter (S), and its method is called crawling. The earthworm moves by crawling by the successive contraction of its circular and longitudinal muscles of its body, which helps it to crawl in a movement called worm movement.
Climbing: the lynx moves by climbing trees with the help of its strong claws that enable it to climb easily, and other animals that move by climbing trees and jumping among them are the red squirrel, which is distinguished by its long fingers and claws that enable it to climb, and the squirrel also has strong back feet that help it push its body While jumping, the hairy tail acts as a steering wheel, and a parachute helps to safely land on the ground.
Jogging : Many animals move about running, and an example is predators that run to catch prey.
Jumping: Some animals that have long hind legs jumping, including the American grasshopper, the rabbit, and the frog.
Tunnel digging : Some animals move under the soil by digging tunnels, including the mole, which has strong claws and shovel-like front limbs to facilitate the digging process.
Cows
Cows are considered to be animals that belong to the mammalian family, and ruminants, meaning that they re-chew food for digestion after swallowing, where they store it in their four-part stomach, then re-chew, and female cows are called the cow, while the male is called a bull, and the little one is called a calf, They are distinguished by their large horns and huge hooves, and people benefit from cows in many works, including plowing the land and rotating the mill, as well as using their milk, meat, and skins. They are considered among the least intelligent animals. Cows are raised in the plains and green pastures, and are usually raised. Around the world, in cold regions like Iceland, and hot as India.
Cow species
We know that can cows swim and now we need to know that cows are classified into two main types :
Milk-producing cows
Cows vary in their ability to give milk, which can be made with cheese , cream, sweets and other things, as the cows are raised on huge farms and are taken care of to provide the best quality milk. Holstein: It is the most famous type of dairy cattle, raised in the Netherlands, and is known for its black and white color. Jersey: It is the smallest breed of cows, and it is originally from the British island of Jersey. Brown Swiss: Native to the Alps in Switzerland, its milk is characterized by its high protein content, which makes it suitable for making cheese. Gwensri cow: This breed of cows is distinguished by its golden color, in addition to the color of its milk that is close to golden due to its containment of beta-carotene, which is a source of vitamin A. Airshire: This breed of cows is considered an aristocratic breed, its origin is from Scotland, and is distinguished by its red and white color, and its rapid adaptation to the surrounding environment . Red and white holsten: its characteristics are similar to black and white holsten, except that they differ in their tolerance to high temperatures, and their strong immune system against diseases.
Meat-producing cows
There are many types of cows that produce meat, including :
The Angus cow : It is native to Scotland, and it is usually raised in areas with heavy rain and is distinguished by its black color, and is famous for its production of calves. Hereford cow: red color, white face, it is native to England, and is distinguished by the production of calves, in addition to its use in crossbreeding. Limousine cow: It is native to France, and is known for its small size, brown color, in addition to having horns, and is distinguished by the density of its muscles and low-fat meat, and thus it is suitable for crossbreeding. Simmental cow: red and white, with horned face, European origin, and is distinguished by producing bulls.
Habitat
Cows live in herds and prefer warm regions, but some have adapted to live in cold regions, today they live all over the world in pens and walled farms called dairy farms.
Food
Cows feed on grasses in pastures and plains, on leaves of young shrubs and on grains such as barley, corn, soybean meal, hay and hay, and they are considered food-consuming animals as they devour about 50 kg of food daily, and breeders on farms are keen to feed them well to benefit from them more in return. She gives more milk and more meat, and is able to work and endure more hardships. Cows drink water a lot and for every two liters of water they produce one liter of milk, and give milk about 10-20 liters per day.
Reproduction The cow reaches the age of maturity at the age of 15 months, the ox at the age of 12 months, and after mating the cow carries one young and in rare cases carries twins, and the gestation period is 9 months, and the cow can bear every year once, and the cow continues to give milk after birth for a period of 10 months She takes care of her baby and breastfeeds him for at least 6 months.
Take care of the cow
Raising a cow animal requires providing appropriate care to it through many preparations such as providing fields and shelters appropriate to the size of the herd, and then starting to take care of the cows by providing their needs of food, water and health, as it is important to deal with a veterinarian with experience in the field of animal husbandry, and in What comes will be talked about caring for cows :
Create shelters and fields A suitable area must be provided for grazing the cows, where a minimum of 2 acres must be provided for each one cow, and if this space is not available, food can be provided to the cows in the form of feed, and then the land is separated into square ponds, with the use of a temporary fence that opens and closes easily to allow a procedure The adjustments are without hassle, and the cows must be taken out for grazing outside the fields and shelters designated for them on a daily basis, and the herd must be placed in high areas in cases of deteriorating weather.
Providing basic necessities A clean water source must be provided close to the herd to provide the appropriate quantities of water that the cows consume, as they need from 1 to 2 gallons of fresh water daily for every 100 pounds of their body, and the appropriate quantities of food for the cows must be preserved, whether in the form of herbs or fodder. Suitable feed should be provided to the cows in clean containers, making sure not to mix them with water, and certain quantities of salt must be provided, as they need to be consumed daily to maintain their health, as one block of rock salt can be placed in each field.
Benefits of an animal cow
The process of using the cow animal began since prehistoric times, when a person’s wealth was estimated depending on the number of cows he owned, as cows are very useful animals for humans, as they can benefit from their meat and milk, and their skins can be used and their strength can be used to pull carriages. In what follows an explanation of the benefits of a cow animal :
Dairy
Cows can be specially raised in order to benefit from their milk, as cows for milk production are raised in the pastures or inside pens, taking care to provide adequate quantities of herbs and feeds for them, so that the milking process is done twice a day, and then the milk is transferred to the dairy factories To convert it into cheese, dairy, butter and many other dairy products.
Meat
Beef can be used in several ways, as all its parts can be used, as the meat is used as food for humans or pets, and all that remains from the cow's animal can be used as soil fertilizer , and many products can be made from cows; Like soap, paint and many medicines.
The work
Where males can be raised from cows as working animals, as the bull begins to work at the age of four years, and can be used to pull carts and plows, it is capable of sufficient to pull heavy loads such as tree trunks , or it can be used to operate large machines such as mills and irrigation pumps, and there are still many From countries, cows are used in various works, especially in poor countries.
The principle of operation of the stomach of ruminants
Ruminants include about 200 species of mammals, which include cows, goats, and sheep. Ruminants are known for their ability to store large quantities of food in the stomach for re-chewing at a later time, as the stomach of ruminants consists of 4 compartments that help them in the process of regurgitation These compartments are; The rumen, the retina, the leaf, and the real or inflated stomach, where both the rumen and the retina in the process of fermenting food and breaking down complex carbohydrates such as cellulose, depending on the saliva produced by the ruminants and the microbes inside them, as the food is mixed with saliva and separated into layers of solid and liquid materials. After this separation process, the liquid layer is destroyed by the internal microbes present in the first two chambers, while the animal returns the resulting solid layer to the mouth to chew it and mix it with saliva again, and then the digested material is transferred to the leaf room, as this chamber regulates the transfer of materials. The digestive system of the appropriate size to the real stomach, as it absorbs ammonia and some types of fatty acids , and then the real stomach releases a group of acids and enzymes to break down the nutrients further, and then these nutrients move to the intestine to complete the digestion process.
How to determine the age of a cow
The age of the cow is determined through a dental examination, as the temporary teeth grow as soon as the cow is born, and all the incisors appear within twenty days of birth, and during the thirty days the first, second and third pairs of temporary molars appear, and in the sixth month, the teeth grow significantly, In addition, the fourth permanent molars appear during the fourth month, the fifth permanent molars in the fifteenth month, and the sixth permanent at the age of two years, and the number of temporary teeth decreases within twenty-one months, and they are completely replaced between the thirty-ninth month and the forty-fifth month.
Signs of the birth of a small cow
Signs appear on the cow when her due date approaches, as colostrum is produced, the pelvic ligaments of the cow relax, and the bean swells, and reaches six times its normal size, and flabby, in addition to that, cartilaginous white mucus is secreted from the vagina, and the cow begins to pump the udder a week before Up to two weeks before calving, but this sign is not reliable in female calves that become pregnant for the first time.
Feeding a small cow
Calves are fed from mother's milk until they are between 8-9 weeks old, and it is necessary for a small cow to eat his mother's milk from the first moment of birth, because mother's milk contains antibodies that protect the calf from various diseases.
Cow voice
The voice of a cow is called the language of many names, including :
Khawar : where it is said khar, khoor, and khwar, which is the sound of the bull, and the sound of a cow or a calf if it becomes stronger.
Bogam : where it is called mumb, mum, and mumba, and it is usually the sound of camels, and it may be called the sound of a cow.
Thuaj : where it is said to be cows, thaj, thuaj, and thuaj, which is one of the sounds of cows.
Bell : It is the sound of the bull and the cow.
Humming.
