pistachio shells in livestock feed

I think, you must be clarify some things;
1- amount of its production
2- analysing its component
3- which part of the diet it is going to be replaced
3- is it availabel During all the year
4- its cost for consumer

We worked together on this issue with the Animal Research Center in Kashmar, Iran.
If the silage dry leaves and stems, pistachio shells, and then use it to feed the sheep.
If cost is much work to harvest and then dried pellets or beet pulp is processed.
I want to know more and Agriculture Organization of Khorasan write.

Dear All
I think Pistachio shell powder is a useless residuals in animal nutrition. Me is from 0.99 to 1.3 M cal-kg DM with 1.5-3.5 % CP. It lacks characteristic to ruminate (PeNDF) but straw plays important role to secret saliva and pH adjustment in rumen. Degradability rate measured in USA was zero percent.
