Meat, milk, or wool?Sheep are multi-purpose animals, raised for meat, milk, and wool. They are also valued for their skins and hides. While sheep have been used to control unwanted vegetation for centuries, grazing as a fee-based service is a relative new opportunity.One of the first and most important decisions a shepherd must make is to decide what aspect of sheep production to focus on. While most sheep are multi-purpose, there are breeds which are better suited to meat, milk, or wool. Production practices will also vary according to the emphasis of the flock. Meat Sheep Meat sheep producers sell either slaughter lambs or feeder lambs. Slaughter lambs are usually purchased for immediate slaughter. The average slaughter weight for lambs in the United States is 135 lbs., though lambs sold into ethnic markets tend to be much lighter (< 100 lbs.). Increasingly, there is a market for slaughter lambs of any weight. Feeder lambs are lambs kept for the purpose of feeding for slaughter. Feeder lambs range in weight from 50 to 90 lbs., with the demand usually being the highest for 60-70 lb. lambs. Increasingly, lamb feeders have to compete with the ethnic markets for light weight lambs. In a meat sheep enterprise, the primary factors which determine
profitability are percent lamb crop, lamb growth rates, and
market prices. Unless feed costs are very low, it is difficult
to make a profit from a ewe that produces just one lamb. Lamb Feeding In a lamb feeding enterprise, feeder lambs (50 to 90 lbs.) are purchased and fed to finish weights of 100 lbs. or more. The major cost in finishing lambs is feed. Lambs can be finished on a variety of diets: complete pelleted rations, whole grain rations, or high-forage diets. Cheap gains can often be put on lambs on pasture or crop aftermaths. Hair Sheep Hair sheep do not produce a fleece. They naturally shed their coats (mixtures of hair and wool fibers) and do not require shearing, crutching, or docking. Hair sheep tend to be more resistant to internal parasites (gastro-intestinal worms) and other pests than wooled sheep. In addition, hair sheep breeds possess many desirable reproductive characteristics, such as early puberty, out-of-season breeding, and prolificacy. Hair sheep are promoted as an "easy-care" alternative to wooled sheep and traditional production systems. Hair sheep ewes are often lambed on pasture. Lambs are commonly grass-finished. Because hair sheep production continues to grow, there may be a good market for hair sheep breeding stock. Many hair sheep producers sell their ewe lambs as breeding stock and their male lambs for meat. Wool Production Selling wool in the commercial wool market has limited profit potential, but niche marketing wool can pay big dividends. For example, while wool sold commercially may bring only 75 cents per pound, fleeces sold to hand spinners could bring as much as $15 per pound. Many producers process their own wool into yarn, roving, blankets, or crafts and market value-added products. There are several cooperative ventures in the U.S. that will add value to producers' wool. Fleeces sold to hand spinners need to be of high quality. Feeding,
housing, health care, and handling are all critical to the production
of good quality wool. Fleeces should be skirted. Skirting is
when you remove the undesirable parts of the fleece. Parts which
should be removed from a fleece include belly wool, tags, stained
wool, coarse wool, cotted wool, and short wool. Sheep Dairying Sheep's milk is usually made into cheese. Some milk is made into yogurt and ice cream. Fresh sheep's milk is seldom consumed. Milk can be sold to a processor for conversion to cheese or the milk can be processed by the producer and marketed as a value-added product. While any breed of sheep can be milked, there are specialized
dairy sheep breeds, much like there are specialized breeds of
cattle and goats for dairy production. Examples of dairy sheep
breeds include the East Friesian of Germany, Lacaune of France,
Chios of Greece, British Milksheep of the U.K., and the Awassi
and Assaf of Israel. These breeds will produce from 400 to 1,100
pounds of milk per lactation. U.S. breeds which are best adapted to dairy production are Dorset and Polypay. They only produce 100 to 200 pounds of milk per lactation. Crosses between domestic breeds and specialized dairy breeds average 250 to 650 pounds of milk per lactation. The nutritional requirements of dairy ewes is significantly higher than ewes being raised for meat and/or wool. Total feed requirements will depend on lactation length. Some feeds can impart undesirable flavors to the milk (e.g. fish meal) and should not be fed in large quantities during lactation. Dairy ewes have the highest water requirement of any class of sheep at approximately three gallons per head per day. While most non-dairy producers wean their lambs at 60 days
of age or later, dairy lambs are weaned at 30 days of age or
younger, so that the ewes can be milked when they are still
producing adequate amounts of milk. Milking facilities and equipment
will be the biggest expense in a dairy sheep operation. The
type of milking parlor may vary according to the size of the
operation. Producers milking less than 50 ewes may utilize a
platform for milking, whereas a "pit" parlor is desirable
for larger operations. Seedstock Many sheep farms specialize in the production and sale of seedstock or breeding stock. Breeding stock includes ewes and rams, purebred registered animals as well as commercial crossbreds. Customers for breeding stock may be other seedstock producers or commercial sheep producers. In areas where there is a large commercial sheep industry, producers may find ready markets for rams. One avenue to sell rams is to participate in Central Ram Performance Testing Programs. In a ram test, rams are evaluated for rate-of-gain, feed efficiency, structural correctness, and breeding soundness. Inferior rams are usually not allowed to sell. Consignment sales, production sales, and private treaty sales are other means of selling breeding stock. Record keeping is an important aspect of seedstock production. The National Sheep Improvement Program (NSIP) is a computerized performance record keeping system for small ruminant producers. NSIP allows the comparison of sheep from different flocks under different feeding and management systems. Producers can also do their own on-farm record keeping. There are various computer programs available for this purpose. Nowadays, it is recommended that breeding rams, especially those sold to other seedstock producers, be blood tested for scrapie genotype. Rams with susceptible genotypes (e.g. QQ) should probably not be sold for breeding, if progeny will be kept for breeding. QQ rams can be used to produce club lambs or as terminal sires in commercial flocks where all lambs will go to slaughter. Scrapie is not a genetic disease; however, an individual's genotype determines whether it will get scrapie if it is exposed to the infective agent. Producers of breeding stock are also encouraged to enroll their
flocks in the Voluntary
Scrapie Flock Certification Program (VSFCP). The VSFCP is
a monitoring program for scrapie administered by USDA-APHIS.
It involves an annual flock inspection, record keeping, and
ear tagging. After five years of scrapie-free monitoring, a
flock can be certified as "scrapie-free." Club Lambs |
