Where does a shofar come from? Ram’s horn shofars, which are traditionally used on Rosh Hashana by almost all Jewish communities, are made from sheep horns, while kudu horn shofars, sometimes referred to as a Yemenite shofar, are made from the horns of the kudu antelope. Kudu are found almost exclusively in southern and eastern Africa.
Unlike deer antlers, these true horns from rams and kudu antelopes have a bony core that is really an extension of one of the bones from the animal’s skull. The skin layer that covers this core of bone contains the protein keratin that makes the horn, and later the shofar, extremely strong and durable.
No two animal horns look exactly alike and no two shofars sound exactly the same. As a ram or kudu grows older, the horn gets larger and becomes more and more twisted, forming a curve or even a spiral. Horns of older rams or kudu antelope may form two or three complete loops.
Today larger ram’s horn shofars are more difficult to obtain due to widespread animal diseases and strict veterinary requirements of the Israel Ministry of Health, which oversees their import, but long jumbo Yemenite shofars are quite common.
