4 BULLETIN 73 . 
tention recently. We are now ready to publish bulletins 
giving the results cf a series of experiments which have been 
carried out to throw light on these questions. An experi¬ 
ment has been carried out on the sub-station at Rockyford 
by Mr. Griffin, to show the value of beet pulp combined with 
alfalfa for lamb feeding. In the present bulletin we give a 
brief resume of the value of beet pulp as determined in other 
places and report some trials in which beets and pulp were 
fed to cows on the College farm at Fort Collins. The in¬ 
formation of the value of pulp as determined in other places 
has been gleaned from every available source which we have 
reason to believe is reliable and in connection with our own 
investigations will give our farmers and stockmen some 
basis upon which to decide whether or not it will pay them to 
feed pulp to their stock. In addition to this bulletin, we have 
ready for publication a bulletin on “Swine Feeding in Col¬ 
orado" which reports trials with beets and pulp and which 
gives the only information we know of about the value of 
beet pulp for hog feeding, and also a bulletin entitled “Lamb 
Feeding Experiments in 1901-1902," in which will be report¬ 
ed the results of our trials of pulp and beets in rations for 
fattening lambs. We speak only of the diffusion puip such 
as comes from our factories. 
COMPOSITION OF BEET PULP. 
Professor Henry in his book “breeds and Feeding” gives 
the result of sixteen analyses and seven trials of digestibility 
of beet pulp, which shows the following composition. The 
digestible nutrients are given: 
BEET PULP. AVERAGE OF l 6 ANALYSES. 
Dry Matter. Protein. Carbohydrates. Ether Extract. Nutritive Ratio. 
10.2 '0.6 7.3 - 1:12.2 
Analyses made by the California Station, published in 
their bulletins, show a nutritive value considerably higher 
than the above. These analyses also show the comparative 
value of beet pulp, pulp silage and sugar beet silage. 
The digestible nutrients only were calculated.
