Introduction
When a new sheep producer enters the sheep industry or when existing
producers contemplate a change in their farming enterprise, many different
things must be considered. The resources that are available on the farm
must be evaluated and the proper production system used to maximize the
farm resources available.
The sheep producer must consider the land, buildings, labour, the machinery
resources available on the farm and the market that the shepherd has access
to before a sound business decision can be made. If all farm resources
are not evaluated the sheep enterprise will underutilise the resources
available.
Land
Do you need to own the land to farm it and raise sheep on it? Of course,
the answer is no. Many producers are under the impression that you must
own land to be a farmer or raise sheep. In many cases it is likely most
economical to rent your land and buildings. The extra debt load imposed
on the farming business by insisting that the land be owned, may be enough
to make the farm business unsuccessful. Renting of the land and buildings
may make the farming enterprise more viable.
Unless you have an off-farm source of income to pay for the farm mortgage,
renting may be the only viable alternative The productivity of the land
must also be evaluated to determine the pastures carrying capacity and
the estimated yields from crop production.
Buildings
The farm buildings must be evaluated to determine the space available
for the sheep, the space available for feed storage and the suitability
of the building for winter lambing. The ewe requires 10 - 20 square feet
depending on the stage of production. Dry ewes need a limited amount of
space, 10 square feet or less. Lactating ewes need 15 to 20 square feet.
Dry ewes are easier to house than lactating ewes; dry ewes can be kept
in open sheds. When lactating ewes are housed, pen space and feeder space
becomes extremely important.
In many cases it is the amount of feed space in the barn that determines
the number of sheep to be kept. Pens should be long and narrow. If you
allow 16 inches head space per ewe and the pen depth is 11.5 to 15 ft.,
then the space provided to the ewe will be 15 or 20 sq. ft. Walk through
feeders are very useful when feeding lactating ewes.

There are 4 areas where the ewes can eat, therefore the barn will accommodate
a ewe for every 4 inches of barn length.
Example: 64 ft. of barn length to accommodate sheep/4 inches = 192 ewe
housing capacity.
It is also important that there is area available to house rams, so breeding
rams can be removed from the flock when necessary so lamb groups can be
organised.
Is the barn suitable for winter lambing? In most cases sheep dont
need to be kept warm but at lambing time a warm dropping or lamb area
may need to be provided in order to reduce lamb mortality from hypothermia.
It is important to keep this area warm and dry at lambing, not humid and
damp. An insulated area may be necessary for winter lambing.
Space for feed storage must be adequate. A ewe will consume approximately
750 lbs of hay and l20 lbs of mixed grain during the winter, if lambing
in the winter. Round bales of hay could be stored outdoors to reduce building
storage costs.
Labour
Labour is essential and an important input in a sheep enterprise. The
amount of labour required will depend on the individual farm set-up and
the degree of mechanization on the farm. Caring for the sheep is the most
important job and observation time is also important. You must continually
evaluate your sheep and watch your flock to assess condition and to determine
their needs. When evaluating labour requirements consider the distribution
of the labour required throughout the year. Lambing time requires more
labour. You may have to evaluate the labour requirements of a number of
enterprises at the same time to establish labour requirements for the
entire farm.
Machinery
What equipment do you need to operate a sheep enterprise? If you pasture
your sheep you will likely need equipment to clip pastures and perhaps
spread fertilizer. You will need to remove manure from the sheep barn
and yards. The equipment needed could consist of a 40 to 65 h.p. tractor
with a loader, a rotary mower and perhaps a manure spreader. Additional
equipment may be needed for the cropping enterprise depending on the amount
of hay and grain needed for the flock. It may be cheaper to buy your hay
and grain than produce it yourself when you consider the cost of haying
and harvesting equipment and the labour required. If the forage and grain
is purchased off the farm, the shepherd has the opportunity to expand
the flock by using more land for pasture and having more time available
to look after the flock. Utilizing custom operators may also be a viable
alternative.
Markets
Sheep producers in Ontario are very fortunate to have a number of markets
available. Sheep producers can sell lambs from 40 to l20 lbs at the market
place depending on the time of year. There is great potential to expand
the market for Ontario lamb if a constant supply of lambs was available
from the production sector.
Production System
Once you have evaluated the land, buildings, labour, machinery and markets
available the production system that most efficiently utilizes these farm
resources can be determined. There are a number of production/management
systems available to the sheep producers. Below are the advantages and
disadvantages of these production systems.
| |
Advantages
|
Disadvantages
|
|
Grass Lambing (April-May)
once a year
|
1. Lower Feed Costs
2. Lower lamb mortality
3. More ewes/person
4. Lambs need very little, if any, extra feed to be finished on grass
5. High nutritional demand by the ewe is satisfied by the pasture
6. Reduced housing costs |
1. Deworming costs increase
2. Decrease in selling price/lb |
|
Winter Lambing once a year (Jan.-Feb.)
|
1. Lower worm loads
2. Improved market potential
3. Lambs grow well |
1. High lamb mortality 15%+
2. High feed costs
---nursing ration
---creep feed
3. More health problems
4. More management & labour
5. Less ewes can be handled per person
6. Increased housing costs |
|
Accelerated Lambing/Star Lambing System
|
1. Year round supply of lambs
2. Market price stability because of increased number of marketing
dates
3. Lambs marketed at Christmas & Easter
4. Lower lamb mortality
---2 warm season lambings
---1 cold season lambing
5. More lamb marketed per ewe
6. 1/3 to 1/2 of the flock lambing at once
---less lambing barn space needed |
1. Management is more intensive
2. Insulated lambing areas needed
3. Higher feed cost/ewe/year
4. Maybe more udder problems? |
The production system, based on these advantages and disadvantages best
suited to the farm resources should be used to efficiently use farm resources.
Easter May Not be a Very Profitable Market
If you look at the price of new crop lambs in the month, in which Easter
fell for the last 4 years, the average price per hundredweight (cwt.)
for 50-64 lb lambs was $237.36 and the average weight was 57.3 lbs. generating
a gross of $136.01 per lamb.
When you examine the price of the heavy lambs in Sept and October for
80 to 94 lb lambs, in the last three years, the average selling price
per cwt. was $150.64, and the average weight of lamb was 86.8 lbs., generating
a gross of $130.76 per lamb.
When you consider that the lamb mortality in January and February is
in most cases twice as high as in April and May, the newcrop lamb market
at Easter perhaps is not as good as you might have thought. The feed cost
and labour involved in raising newcrop lambs for the Easter market are
much higher per lamb than for heavy lambs born on grass and marketed in
the fall. If you lamb your ewes once a year you may consider lambing more
of your flock in the spring if your resources allow it.
Once the farm resources have been evaluated and the production system
is chosen that best meets your farms resources, the next step is
to evaluate the breeding stock available and match them to the production
system chosen. The traits in the dam line that are more important are
similar across all production systems; however, some traits may be more
important depending on the production system. All our dam lines should
exhibit good fertility, prolificacy, longevity, mother and milk well,
be of a medium size, be easy to feed and give birth to lambs with good
liveability. When lambing on grass a dam line that exhibits hardiness
may be desired and when lambing every 7.2 to 8 months, a ewe that breeds
out of season and exhibits early sexual maturity would be beneficial.
Selecting the proper breeds to fit the production system is extremely
important.
When making decisions about the production system that should be followed,
all farm resources must be taken into account. In many cases, the production
system is determined and the farm resources are adapted to fit the production
system. Better management decisions can be made if the resources are identified
first and the production system fits the farm and the resources, instead
of the farm and the resources being adapted to fit the production system.
