Shel,
Please note that the beet pulp was listed under concentrates.  It is not 
used for a protein component, so much as an energy component.  Pound for 
pound it has about the same digestible energy as corn.  The difference 
is that the energy comes from digestible fiber in B/P whereas the energy 
from corn comes from starch.  Corn is about 90% dry matter, 77% Total 
Digestible Nutrients (TDN), and 8.9% Crude Protein.  Beet pulp is about 
91% dry matter, 72% TDN and 9.1% protein.

So you can see that the actual nutritional value of Beet Pulp is very 
close to that of Corn.  The difference is in how it is digested.  One of 
the important aspects of ruminant digestion is that of protein.  Now, as 
I understand it, there are a couple of different types of protein, one 
bypasses the rumen and is digested in the intestines.  The other is 
amazing...the little microbes in the rumen actually feed on the 
cellulose - fiber - of plant material.  Then, if I understand correctly, 
as these little microbes die off naturally, they pass into the 
intestines and become protein for the host animal.

So that is why beet pulp is widely used as an energy source for 
ruminants.  Starch (corn) in large quantities kills off those little 
microbes that feed the ruminant and lead to the inability of the 
ruminant to take in large quantities of fiber because there are fewer 
microbes to digest it.  That is also why it is an acceptable component 
in a "grassfed" animal's diet.

I am still scratching my head though...I know how much BP expands and I 
know how little room there is inside a ewe carrying twins.  Perhaps that 
is the wisdom in the ration that includes barley in the article you 
posted.  BTW, barley contains a B vitamin that is not present in corn. 
I forget which one, but it's pretty important.

Jeez I'll be glad when I have the confidence of having made several 
right decisions behind me!  LOL!  Thank you for sharing Shel, I am going 
to go back and look at that ration formula real hard!

Regards,
Barb
