The NSC is not a value that I use for evaluation. The laboratory analyses that I use to evaluate feeds are % starch, % ethanol soluble carbohydrates (ESC) and % water soluble carbohydrates (WSC). These three analyses provide different information.
The forage pellet company that makes the teff pellet does not have information on % starch and % WSC. However, published data on teff hay reports % starch as less than 1.0%, % ethanol soluble carbohydrates approximately 4.3%, and % water soluble carbohydrates approximately 6.1%. Teff hay is a warm season grass and generally will have lower carbohydrate analyses than cool season grasses.
I actually like teff hay but the west coast horse owners are not using it. The lower demand means less will be grown and perhaps teff hay will not be available in some regions in the near future. I hope not because horse owners are missing out on a good alternative to other west coast grass forages.
