Sheep breed identfcaton There are more than 600 sheep breeds worldwide. You are asked to remember only a very few of these. Refer to the alphabetcal list below, of sheep breeds found in Australia and be able to identfy/recognize the breeds of sheep that are in CAPITALS bold type and know what their origin and main purpose is (viz wool, meat, dual- purpose). If you intend to work in a country other than Australia, look up the relevant breeds for that country . Some hints to make it easier to remember which breed is which 1. Which breeds have horns? 2. Do both ewes and rams of these breeds have horns? 3. Are horns a dominant or recessive trait? 4. Which breeds have coloured feeces? 5. Which breeds have coloured faces/legs? 6.

Domestcaton of sheep is thought to have taken place in the area of the borders of present day Iran–Iraq about 9000 years BC. Sheep and goats were the next animals to be domestcated afer dogs. They then spread to Asia, Europe and Africa and 200 years ago to South America, Australia and New Zealand. Domestcaton i.e. breeding controlled by man has resulted in breeds which serve the needs of human populatons for food and clothing. Few of the more than 600 diferent breeds of domestcated sheep (Ovis aries). are present in Australia. Accurate natonal statstcs on sheep breed numbers are no longer kept in Australia. The Merino The Merino is stll the most important sheep breed in Australia making up approximately 80% of the sheep populaton and many sheep are part merino, for example: Downloaded by Fred Mundy ([email protected]) lOMoARcPSD|4090111

The Corriedale is ½ Merino The Polwarth is ¾ Merino Merino Crossbreds are ½ Merino or less Comebacks are ¾ Merino or less The Australian Merino is primarily raised for its heavy feece of fne quality wool. There are four basic strains of merino; Peppin, Saxon, South Australian and Spanish. Many other breeds are represented in Australia and although their total numbers are small by comparison with the Merino and its derivatves, they do play a part in the Sheep Industry. The origin of many of the present day breeds is obscure. This is because the breeders who were responsible for producing the more or less uniform focks of these breeds divulged litle. They were usually concerned with selling the end product rather than documentng the means to the end. It is important to remember that present day breeds are the end result of one or more of three methods of selecton and breeding.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
