Strange purposes when training animals (2)

The problems from illness, military to gardening all have interesting help of animals.

Throughout history, we humans have evolved, becoming the dominant animal on earth. And of course, most other animals have been left behind and within human control. We have studied, investigated and used the unique characteristics of animals to help our lives. Typically, we use horses to move and transport dogs, domesticated wild dogs into housekeepers, to make scenes or raise livestock to get food for life.

Obviously, the things that animals have done for our lives are so many, it's hard to tell. Among them, there are many things that happen daily, normally, but there are also quite a lot of special and strange things. Here, let's point out some of the most mysterious and confusing tasks that humans have used to do animals in history.

Military dolphin

Normally, if used for war and military use, we often think of animals such as dogs, horses, elephants, . often species that live on land associated with the task of transporting or sniffing. However, it is only in the past, modern technology has helped them take advantage of both flying birds such as falcon, eagle and swim underwater like dolphins in the military face.

Dolphins are mammals living in oceans and rivers that are closely related to whales. There are nearly 40 species of dolphins belonging to 17 genera living in the oceans, the few remaining in some rivers of the world. The size of dolphins can range from 1.2m and 40kg (Maui dolphin), up to 9.5m (30 ft) and 10 tons), Tiger dolphin or killer whale. Dolphins are found all over the world and often live in shallow seas of the continental shelf. Dolphins are carnivores, mainly eating fish and squid. The ocean whale Delphinidae is the largest family of dolphins and they are also the latest: about 10 million years ago, in the Mid-Tan.

Dolphins are one of the most intelligent and well-known animals in human culture thanks to their friendly and mischievous attitude. Among them are the bottlenose dolphin, which is a species with good vision and communication. The smartest in the animal world. Thus they have been used by humans in many fields including military.

Some of these species activities include protecting anchor vessels from intrusion. Recovering equipment falling into the sea. Compared to many advanced equipment and special forces, dolphins have brought good results, much more savings.

Monkey helps harvest coconut

Coconut picking is a very time-consuming and labor-intensive task. It requires us to use our hands and feet, machines almost without help. This work is also quite dangerous, if the coconut falls on people or falls during harvest, the consequences may be very serious. However, in India and Thailand, farmers have trained monkeys to work for them. Training each monkey will take 6 months or more. Owners will control their monkeys with a long chain and reward them with food after each shift.

Species are inherently known for their excellent climbing ability and ingenuity in hand manipulation no less than humans. Their help not only helps lessen the risks for farmers but also increases productivity by 5 to 8 times that of humans.

Use sheep to prune trees

We often know the effect of sheep is to bring fresh meat, fat, skin, fur and milk to humans. This is one of the earliest domesticated animals. Sheeps in the world today are over 1 billion. Sheep are easy to eat, can eat arid grasses, prefer dry climates, do not tolerate wetness. Much rearing in dry areas, desert and half desert, especially subtropical regions. Another use of them that few people know is to use pruning leaves for wine vineyards.

In Napa Valley - the famous wine growing area of ​​the United States, sheep were given this job. In order to have quality wine vineyards, it is necessary to remove weeds and vines that must be trimmed to avoid mold. However, doing these jobs takes a lot of time and money, but sometimes the efficiency is not high, so people are very smart to use sheep. To avoid them eating whole grapes, people will place small charged wires on the bunches of grapes. In addition to the ability to clean grass and prune leaves, their excreta is also an excellent source of nutrition for vineyards. A small herd of sheep can trim an area of ​​more than 20 acres a day.

Cormorants help catch fish

In China and Japan, cormorants have been used as a powerful assistant to catch fish from 960 AD. More than 1,000 years have passed but this species is still being used very effectively. The cormorants are trained for many years, they will automatically fly away to catch fish and bring the fish to the basket for fishermen. In order to preempt the greed of the cormorant, the fisherman will tie the rope to the birds' necks so that they cannot swallow the fish.

Birds are obviously more capable of vision and reaction than humans, catching them is very simple and quick. Although the big fish are not allowed to eat, small fish are usually considered a reward. A relationship that benefits both parties has been maintained throughout history. Until now, due to the development of technology, the use of cormorant birds is no longer popular as before. But it still exists and is considered one of the features that attract tourism in China.

Use the horse to lead the way

Humans began domesticating horses around 4000-4500 BC and it is believed that horses were popularly cultured in Europe around 3000 BC-2000 BC. War horses were widely used in war, especially in ancient times. In modern times, horses are also used to transport, move and take leather, meat and feathers.

The use of guide horses sounds ridiculous. Normally, species often help guide us as dogs because of their agility and compactness. In modern times, people with vision loss or blindness often use animals to lead the way. Dogs are of course good, but not everyone likes them or they just have allergies. So often these cases use horses instead. Horses are also intelligent and easy to train, and stamina is better than dogs.

In 1998, people began to devise plans to train horses to guide their owners instead of dogs like before. The horse itself is also very gentle, and does not cause allergy to the owner. If a guide dog usually only uses 8-10 years, the life of the horse is quite long, about 30-40 years, this can help people use them longer.

Rat species detect tuberculosis

Tuberculosis is a big problem in Africa - an area with enough infectious factors such as poverty and crowds. Tuberculosis is a disease that can be cured if the person is diagnosed early. And in a contagious environment like the poor countries of Africa, diagnosing the disease also helps to prevent infection more quickly and efficiently. The main problem is that tests for TB samples are often costly and time consuming.

The problem seems to have been brighter when the Apopo team found a method to use mice to detect samples of TB infection. They are able to detect disease quickly and effectively if trained in accordance with the process and method, it is 20% more accurate than the traditional method. The average cost of training for each training session is about $ 8,000, which seems expensive but in return they can be used for about 8 years. This research has opened hope in controlling and preventing tuberculosis in Africa.
