Thanks folks. That's the same recipe I've seen before, it's just very expensive to get all the chemicals. Eventually tracked down a UK company that supply a concentrate form from ANKOM, £60 for about 20L.

Answer to effect of camel milk on diabetes:

Camel Milk Helps Prevent Diabetes

Posted on April 27, 2014 by Daniel Henryk Rasolt

In a country with far and away the highest incidence of diabetes in the world, a potential preventative treatment has been found in an unlikely place; camels. According to researchers in Bikaner, India, camel milk contains sufficient levels of insulin to help prevent, and perhaps treat, both type 1 and type 2 diabetes.

You can find the recommended procedures that are widely used here:

dietary fiber, neutral detergent fiber, and nonstarch polysaccharides

Definitely yes, You can find quality assurance for animal feed analysis laboratories. FAO Animal Production and Health  Manual No. 14, published at Rome, Italy. or you can collect  from J  Dairy Sci. 74: 3583-3597

Check most Animal Feed analysis manuals. in addition to the ones given above, you can also check the one from ICARDA, it is good also and can help you in the work.

thanks

Dear one, the standardized procedure is:

Mertens, D. R.  Journal of AOAC International, Volume 85, Number 6, November 2002, pp. 1217-1240(24).

Remember, fiber (aNDFom) is an empirical measure determined exclusively by OPERATIONAL CONDITIONS. Therefore, results, if one wants to produce comparable results, at least, must follows the standardized procedures exactly.

If you do not want to use the reference method above, the Reference Van Soest et al is an important one, because he provides the 8M Urea solution for pre-soaking amilaceous feeds and emphasize the facultative use of sodium sulfite. Nevertheless, the use of Amylase is mandatory too. The problem with amylase, however, relies on the fact that it also contains fibrolytic activity. That´s why Mertens (2002) provide the way for stadardizing the amylase solution to clear enough starch without damaging fiber.

Please check the recommendations for nomenclature on fiber provided by the editorial board of Anim. Feed Sci. Technol.
