• A strong demand for lamb and goat meat has led to a resurgence of interest in sheep and goat production

• Small ruminants (sheep and goats) work well for small acreages or as a supplementary enterprise with cattle

• Sheep and goats offer many advantages to livestock farms

• Goal: to learn at least five advantages of small ruminants and five challenges, and be able to decide which species to raise in a given situation

Small ruminant production

• Ruminants• Similar size • Gestation length• Similar diets• Fencing

requirements• Facilities• Multiple births

Sheep and goats

• Small size• Requires little feed or land• Prolific and productive• Strong market demand: good prices• Useful in vegetation control

– weeds, brush, multiflora rose, invasive weeds, including sericea lespedeza, kudzu, others

– good companion grazers with cattle; pasture improvers

Similar advantages

• Meat (many ethnic groups prefer goat or lamb, especially for holidays and festivals)

• Milk• Fiber (wool, mohair, cashmere)• Weed and brush control• Skins/pelts/leather• Pets and hobbies (we might as well

admit it!)

Uses of sheep and goats

• Internal parasites• May be difficult to contain• Markets MAY be harder to locate• Predator problems

• Prejudice from cowboys

Similar problems

But sheep and goats are not the same

Sheep Goat• ram = buck (or billy)• ewe = doe (or nanny)• lamb = kid• wether = wether

• lamb meat, mutton = cabrito, chevon

Terminology

• Sheep– Prefer short, tender vegetation; graze very

close– Eat a variety of weeds

• Goats– Selective– Prefer to graze taller plants and browse– Intake drops quickly if forage is too short– Opportunistic (think of deer)

Cattle

• Complementary to cattle

• Can add one ewe per cow with no additional feed costs and no detrimental effects

• May improve profitability per acre by 25% over cattle alone

Small ruminants in combination with cattle

• Maximize the use of resources (forage, labor, facilities)

• Improve pastures by– encouraging diversity of plants– reducing clumps– controlling weeds and brush– reducing parasite infestations on

pastures

Multispecies grazing – benefits to sustainability

• Meat production per species and per acre is higher

• Increases flexibility and options–marketing–managing forages

• Diversified income sources –reduce risk– improve cash flow

Multispecies grazing – benefits to sustainability

• Mob grazing--all run as one group• Leader/follower--matching animal

with highest requirements to forages of highest quality

• Alternate grazing--one portion of farm used for one species; switch later (or, stocker steers one year, stocker sheep the next)

Multispecies grazing – methods

• Knowledge• Fences--adapt cattle fences; 3 to 5

strands electric, 4,500 volts minimum• Minerals--avoid excess copper for

sheep (goats can use cattle mineral)• Facilities--sheep will need some

shelter if lambing in cold weather, goats like shelter in wet weather (not fancy)

• Labor--availability and timing

Multispecies grazing – management concerns

• Ratios–dependent on type of forages available

–1:1 to use extra weeds–6:1 (ewes to cows) to maximize pounds of meat per acre

–Lambs and ewes followed by dry cows to utilize rejected forage

Must match nutrition to production stage

Recommendation: 1 to 2 goats per head of cattle

• Grazing height preferred for sheep: begin at 6-8 inches and move when grazed down to 2.5 to 4 inches

Caution!Avoid over-grazing. Sheep can

graze very close to the ground. Management is crucial.


• Question: what are two reasons to avoid grazing close to the ground?

• How could you prevent close grazing?

Grazing management

Grazing Management

Sheep and goats should have 4 to 5% of body weight in dry matter (DM) available daily. (Requirements vary with production stage and size of animal; dairy goats have higher needs.)

Daily intake is most critical!

• Low intakes, excellent rations: average performance

• High intakes, moderate rations: above expected performance

Major considerations for grazing sheep and goats

Grazing management

AVAILABLE FORAGEExcellent forage management will pay dividends in lowered production costs and increased gains and improved health. Daily intake is most critical!

• To lower costs, try to match needs of the animal to the production of the forage.

• Over-feeding is expensive and counter-productive; fat ewes and does do not do well at breeding or lambing time.

• Under-feeding leads to low birth weights and poor milk supplies.

Production stage:

Major considerations for grazing sheep

Must match nutrition to production stage.

Production stage:Breeding--flush with better nutrition

prior to turning in ram or buck and for several weeks afterward

Major considerations

Production stage:

Early gestation--low requirements; fair to good pasture (15 weeks from breeding)

Late gestation (last 6 weeks)--good pasture, 1/4 pound grain (assuming average condition) Caution: avoid pure stands of infected fescue for late gestation grazing


Production stage:

Lactation--first 6 or 8 weeks, high requirements; excellent pasture, or 4 to 5 pounds hay and 1-2 pounds grain. Taper off near weaning.

Ideally, feed ewes with twins on the best forage. Yearling ewes and does also need excellent forage as they are growing as well as lactating.


Production stage:

Dry--very low requirements; may use the ewes and does to clean up pastures at this point. Ewes and does may be dry for 3 or 4 months before breeding.

This allows ewes and does to easily gain weight; do not allow them to become fat!


• Lambs should graze clean pasture• Have salt/mineral mix, fresh water,

shade available• Shear wooly lambs before hot weather• Use low stocking rates and clean up

with cattle or dry ewes or does• Monitor for parasites and treat as

needed (FAMACHA™)

Recommendations for lambs and kids on grass

• Tell three benefits of small ruminants• What are three problems of small

ruminants?• Explain the nutritional needs of a

ewe and doe and how they vary through a year

• What are three advantages of multispecies grazing?

Annual Summary of Productivity and Price

• Goats or sheep?• Is there a difference?

Choosing which small ruminant

Do you like sheep?

Major consideration

• Meat: growth potential– Lambs on pasture with mothers gained

about .5 pounds/day from birth to weaning (Schwulst, 1995, KS data; Rambouillet, Tunis, Romanov, and Katahdin rams used on crossbred ewes)

– Lambs fed 16% protein ration in drylot gained .72 pounds per day for 45-day trial. Another trial later in the summer, .67 pounds per day. (Katahdin-sired lambs, North Dakota data, Moore, 2001)

Differences in productivity

• Lambs grazing alfalfa gained .43 pounds per day, while lambs confined and fed hay and grain gained .46 pounds per day. (feed cost lower for alfalfa-grazed group, Poore and Green, NCSU, 1995)

• Lambs grazing fescue and eating a small amount of creep feed gained .57 pounds per day (Coffey, 2003, Feb. through March)

More lamb gains

• Ross (1972, MU) studied summer gains in drylot; unsheared lambs gained .33 pounds per day, shorn gained .48.

• Lambs in KSU study (Rambouillet, Tunis, Romanov, Katahdin sires) gained .6 pounds from weaning to market; feed/gain about 5.2 pounds/pound of gain; feed intake about 4 pounds a day

More lamb gains

• Brief review of literature found a range of– .33 pound/day to .86

pound/day

– with .5 pound/day being reasonable• reductions in gain during summer heat,

higher gains when supplemented with grain (also higher cost)

So how much can a lamb gain?

• Depends greatly on breeding and on management

• In North Carolina, TN Stiffleg-sired goats were fed hay or hay plus .25 pound/head of 16% supplement. Gains averaged .065 or .091 pounds per day; pounds of feed per pound of gain, 25.6 or 19.3. (Poore and Green, 1995)

• Does it make sense to feed this type of goat?

Goat gains

• Boer influence increases feed efficiency and gains.

• During a 66-day trial where goats were self-fed a 14% protein pellet, ADG;

• Spanish .25 pounds, 10.8 pounds feed/gain

• 1/4 Boer .33 pounds, 8.2 pounds feed/gain• 1/2 Boer .49 pounds, 8.3 pounds feed/gain

(Machen, Texas A&M, 1995)

More goat gains

• In North Carolina, Boer and Boer-cross does averaging 62 pounds grazed small-grain rye, ryegrass, or triticale pastures. Gain approximately .3 pound/day (Luginbuhl, 1998)

• In Texas, Boer and Boer-cross kids nursing mothers who were generously fed gained– .59 pounds and .43 pounds per day– several does weaned more than 100 pounds

of kids at 100 days; that’s 600 pounds of marketable product per animal unit at 100 days post-partum! (Machen, 1995)

More goat gains

• Boer bucks on test at Langston University gained an average of .6 pounds per day.

Range • ADG, .29 to .89 pounds per day• Feed Efficiency 3.98 to 25.6 pounds

feed/gain• Why might you want to know the

gaining ability of the buck you use?

More goat gains

• Very wide variation• Affected by genetics and by feed supply• Unimproved Spanish on range: .025

lbs/day• Fullblood Boer on ample feed: .86

lbs/day• Feed efficiency range for Boers on test:

3.98 to 11.7 pounds feed to pound of gain

So, how much can a goat gain?

• What do the studies mentioned tell you?

• Which animal (sheep or goat) seems better suited to feedlot production?

• What other considerations (besides feed efficiency and rate of gain) are economically important?

Questions:

• Maintenance cost of doe/ewe• Market price of kids/lambs• Prolificacy• Ease of handling• Personal preference• Type of forage available

Other factors to consider

Why raise goats?

• For weed and brush control• As a complementary enterprise to

cattle to improve resource utilization

• For land reclamation• For increased profit potential• More economically efficient on

smaller operations (than cattle)

Why goats?

• In a NC State study, after 4 years of goat grazing pastures containing herbaceous weeds, vines, multiflora rose, blackberry and hardwood sprouts, pastures became dominated with grass and clover.

• In a West Virginia study, goats reduced brush cover from 45% to less than 15% in one season.

Economic comparison

What is the price per pound?

• 1 cow/calf unit + 2 goats/3 acres• 475 lbs. weaned + 180 lbs. weaned =

655 lb.• “free” brush control• In several studies the addition of

goats to a cattle operation added 25% net return

• (also true of adding sheep to cattle operation)

Cattle + Goats =

• Cattle– start with 1 cow– save all females

for 5 years--sell all males

– 95% calf crop– 50/50 heifer/bull

calves– At the end of 5

years:• 5 females in herd• 5 bulls sold

• Goats– start with one doe– save all females for

5 years--sell all males

– 150% kid crop– 50/50 doe/buck kids– At the end of 5

years:•24 females in herd•24 males sold

Increasing inventory/equity

Recommendation: 1 to 2 goats per head of cattle

Goats:• Are similar to sheep in many ways• Offer pasture improvement services• Are a good companion enterprise to

cattle, increasing profits by increasing pounds of meat produced per acre

• Can be profitable if costs are kept low and animals are prolific
