Livestock Programs
Ram Testing Program
The program is administered by the Pennsylvania Department of Agriculture, in cooperation
with Penn State’s Department of Dairy and Animal Science, the Pennsylvania Sheep
and Wool Grower’s Association, and state breed associations. The objectives
of the program are to:
- Provide a genetically sound testing program that would allow both large and small
sheep producers to participate.
- Promote performance testing of sheep in Pennsylvania and acquaint producers with
its overall value.
- Provide a common test for evaluating rate of gain, structural soundness, muscularity,
condition, and estimated carcass merit.
- Provide an opportunity for purebred breeders and commercial producers to purchase
performance-tested rams, which have been evaluated in part under similar, unbiased,
environmental conditions.
The testing facility houses up to 200 Rams in 5 pens for a 77-day feeding period.
Rations are self fed after a warm-up period and contain approximately 1000 lbs.
Oats, 500 lbs Corn, 250 lbs. Linseed meal, 190 lbs. Soybean meal, 50 lbs. Wheat
middlings, and 26 lbs. Minerals and vitamins.
Consignments to the Testing Program
Nomination forms are available from the Center Director. All rams consigned
to the program must meet the following criteria:
- All rams must be out of a registered sire and dam or registered with their national
breed association.
- Senior rams must be born between September 1st and November 30th of the previous
year. Junior rams must be born between December 1st and February 28th
of the current year.
- The breeds of sheep will be divided into four groups:
- Cheviot, Southdown, Tunis.
- Dorset, Montadale, Oxford, Shropshire, Polypay.
- Hampshire, Suffolk.
- Columbia, Corriedale.
- Hair Sheep.
- Crossbreds, Merino, Rambouillet.
- To be eligible for test, a ram should have an adjusted 50-day weight ratio of 100
or higher.
- Minimum weight per day of age (depending on ratio) will be .50 to .55 lbs./day for
breeds in groups A and D & E, .60 to .65 lbs./day for group B, and .70 to .75
lbs./day for group C & F.
- All rams must score at least 12, (scale of 1 to 17) for conformation at time of
delivery.
- All rams must meet health requirements as outlined in the nomination form.
Why should I Consign Rams?
Performance testing of rams provides the seedstock producer important information
about their own genetic improvement program, as well as making a comparison with
other breeders. The advantages of performance testing include:
- rams are tested and fed in one environment with, similar management, so differences
in performance are more likely to be genetic.
- complete performance information is provided.
- progress in genetic improvement can be tracked over succeeding generations.
- interim and final reports provide good advertisements to other breeders and the
general public.
- rams accepted for sale are offered to a larger pool of prospective buyers.
Performance-Tested Ram Sale
An index ratio will be used to rank rams at the conclusion of the test
for sale eligibility. Each breed will sell separately. Approximately
the top 75% within any breed and/or breed group will sell. Some of the information
available for the buyers and sellers of the rams includes:
- breeder’s name and address
- sire and dam
- birth type
- test average daily gain
- weight/day of age
- fat thickness
- shoulder height
- loineye area
- scrotal circumference
Why should I Buy Performance-Tested Rams?
The information generated in a performance-testing program for rams provides
valuable selection tools to increase productivity and profitability for a sheep
flock. The selection of potential sires in the sheep flock is one of the most
important management decisions that are made.
Recent Survey
A recent survey among buyers of rams at the Pennsylvania Ram Test sale has indicated
the value of using performance-tested rams. Nearly one-third of the respondents
indicated there was at least a 20% improvement in production with these rams, and
over half of these sheep breeders said there was at least a 5% increase. Individual
results may vary, but information generated in a performance-testing program has
great value in making selection decisions that are so vital to profitability.
