44 REPORT ON EXPERIMENT STATIONS, 1953
experimental flock have produced fine wool 214 inches in length in 6
months. The sheep are now being interbred for selection and stabilization
of the genes for long staple.
Under range conditions fine wool ewes mated to Columbia and
Targhee rams by the Utah station (coop. USDA) weaned higher
percentages of fat lambs at heavier weights than similar ewes bred
to Rambouillet rams. The Columbia and Targhee sired lambs were
also smoother bodied, more open faced, and had longer staple wool
at weaning than those sired by Rambouillet rams. Percentage of ewes
lambing, number born, and total production per ewe were similar for
the three types of matings. The Utah station reports that lambing
percentages and production of lamb per ewe in the southern Utah
area have been increased materially by pasture breeding, shed lambing,
and other improved practices adopted by sheepmen as a result of
experiment station research.
Seven of the western State agricultural experiment stations in
cooperation with the Department are developing methods and technical
information needed by wool growers in evaluating the quality
of their product, and in improving its market value through better
methods of preparation.
After deducting grading charges, fine wools graded for length at
shearing time by the Texas station showed an advantage of 5.3 cents
per pound in selling price over similar ungraded wools sold at the
Preliminary experiments in marketing grease wool in semiprocessed
form as top and noils by the Wyoming station, indicate that this practice
may have advantages for the wool grower. In these tests, six
lots of graded Fine, 1/2 Blood and 3/8 Blood wools processed into tops
and noils returned average profits above processing costs of 3.7 to 5.3
cents per grease pound.
A well-defined crimp in Fine wool is usually considered an indication
of quality. The New Mexico station found that Fine Staple Wool
with a low crimp ratio (length of crimp/depth of crimp) had a lower
clean wool content, but yielded a higher percentage of top and less
noils than wools with a high crimp ratio.
The Oregon station found that scouring the fleece tags before they
were sold improved their market value 5 to 6 cents a grease pound,
compared with the usual practice of selling them in the grease. At the
Montana station, all off-sorts including tags, crutchings, and sweepings
brought more when sold at the usual discount than when sold in
scoured form. More research is needed on all of these practices before
they can be recommended to growers.
There are four regional studies in the United States having to do
with the improvement of dairy cattle through breeding. The southern
group of experiment stations is emphasizing heat tolerance in
their animals. The eastern group is trying to eliminate diseases that
