Sheep and cows have been part of American history for centuries. They are known for many products such as meat, wool, milk. Sheep play an important role in animal husbandry, especially religious communities and small farmers. In the early 20th century, the sheep industry peaked by 1942. At that time, the industry exceeded 56.2 million heads. After that, at the turn of the 21st century, they gradually fell below 10 million people. This is a record of American history.
The history of the sheep industry began in Central Asia about 10,000 years ago. The essence of the flock of sheep gathered. Because they are effective herbivores that can survive with sparse vegetation, early people can bring sheep to his travels. Nevertheless, humans have discovered the value of sheep as two products. We can provide two necessities of meat and milk as food, and can hide clothes and evacuation centers. The earliest sheep producer used wool as the top. Until 3500 BC, people learned to spin wool. (Latin 110)
Wool itself is a common product in the sheep industry, as with all other sheep products, waste generated can be converted into beneficial products. These products include: lanolin, artist brushes, insulation and carpet mat. There is no baseball without wool by-products, as the ball is filled with wool, sewn with wool thread, rubber liner is made of stearic acid, and the cork center contains processed blood. As an alternative to expensive leather made from cowhide leather sheepskin can be used as an economical alternative. Once removed and processed, the leather can be used for the manufacture of sporting goods such as baseball, rugby, tennis and basketball. In addition, sheepskin leather can replace almost all leather products made from cowhide such as footwear and drumhead.
Like leather procurement, sheepskin is a by-product of processing sheep for human consumption. In other words, sheep are not particularly killed because of their skin. As it is a by-product, the sheepskin supply is limited by the number of sheep processed for the meat. The growing popularity of the "UGG" brand became "power" of recent shortages, and the price of sheepskin rose by 80% from 2010 to 2012. As one of many garments made of animal skins, the manufacture of sheepskin boots has been criticized by animal rights movement, producers have responded by improving the welfare of animals. Animal rights groups asked for boycotts of sheepskin boots and replaced them with synthetic substitutes. In 2007, Pamela Anderson noticed that the boots were made of skin, she requested a boycott on the website.
