Feed Testing

Feed testing – This article, “The importance of feed testing” by Janna Kincheloe, November 17, 2014” is one of the best articles I have read on the topic of feed testing.

This article looks at three key components:

1) Proper Sampling – The article explains how to collect a consistent feed sample

2) Quality Analysis – This article suggests analysis should include:

A typical forage quality analysis costs between $12 and $40 and will include dry matter, crude protein, estimation of total digestible nutrients (TDN), and fiber content. Source CattleNetwork.com 

3) Testing Methods – This article looks at NIR and Wet Chemistry methods:

There are two primary methods of testing forages available: wet chemistry or NIRS (Near Infrared Reflectance Spectroscopy). Wet chemistry utilizes chemical and heat processes to isolate and quantify nutrients, while NIRS results are based on the light spectrum reflected off a sample using a spectrophotometer.

If you want a good reference document on feed testing, check out this article. It is well-written and makes great points.
