[QUOTE="dcara, post: 829866, member: 473"] I found the research paper with pics I mentioned previously. As with the A&M paper I provided a link to, this paper again supports my original statement regarding manure consistency being a good indicator of the plane of nutrition. Apparently additional research has been done because now the consistency is related to specific ranges of CP and TDN. If you are still not convinced of this concept you might want to submit your research data to A&M and the Nobel Foundation and discuss it with them. Heres the link to the paper with pics [url=http://www.noble.org/ag/forage/bsdegree/index.htm]http://www.noble.org/ag/forage/bsdegree/index.htm[/url] As often happens, this discussion has changed focus somewhat. In this case the focus has changed from nutritional requirements to a debate on the moisture content in the forage. I stand by original statement that protein supplement right now may not be required due to the high plane of nutrition in the spring forage which can be evidenced by the consistency of their manure. A position supported by current documented research from multiple sources. About the only thing I supplement in the spring (given my forage base) is a high magnesium mineral to prevent possible Grass Tetany. Regarding your reference to +/-4.5% accuracy. I use the Microwave dry down method when I am haying to determine when to bail. I like to bail between 15-17% moisture.
