Bison

Ratites
10
Introduction Interest in the U.S. Commercial production of ostriches began in 1800’s in South America After WWII a market for meat and leather developed South Africa retains a virtual monopoly on the commercial production of ostriches In the U.S. the ratite industry involves ostriches, emus and rheas
11
Ratites Group of flightless birds that includes – Ostrich – Emu – Rhea – Cassowary – Kiwi
12
Ostrich Largest ratite, largest bird 7-9 ft in height, 200-350 lbs Capable of running 30-50 MPH for up to 30 minutes Stride of 15-20 feet, depending on size 2 toes Long neck Small head Large eyes Short, flat bill
13
Ostrich Male – Black feathers with white on the wings and tail – Feathers become brighter during the mating season Female – More drab – Light gray to grayish brown feathers
14
Domestic Ostrich Result of cross-breeding several subspecies All belong to the species Struthio camelus Initial purpose of the crossbreeding was to improve feather quality Emphasis of breeding today is meat production
15
Emu Second largest bird 5-6 ft tall 125-150 pound – Males are slightly smaller than females Female is dominant Capable of running 30 MPH Three toes Head and neck are grayish blue, black feathers on the head and molted brown feathers on the body. Plumage is course and hairlike

Llamas & Alpacas
21
Introduction & History Imported to the US in the late 1800s to be exhibited in zoos Interest in raising llamas and alpacas increased in the 1970s with the emphasis being on raising and selling breeding stock In addition to breeding stock llamas are used as/for – Pack animals, fiber production, guard animals for sheep herds, show animals, pets Alpacas are used for – Breeding stock, fiber production, investments and as pets. – They are generally not used as pack or guard animals
22
Investment Cost Varies across U.S. Breeding stock – Females $350-$6,000+ – Males $500-$3,000+ – Stud Fees $700-$1500 Trained Pack Animals $2,500-$3,000
23
Registry International Lama Registry (ILR) Closed – This means both parents must be registered in order for offspring to be registered.
24
Characteristics: Llama Wool color – Usually white but may be black – Shades of beige are also seen – A variety of patterns from spotted to solid are also seen Mature weight- 280 to 450 pounds Long necks 5.5-6 ft at the head, 4 ft at the shoulder Life span 20-25 years
