Determination of Volatile Fatty Acids (VFA ) in Silage – Gas Chromatography

1. Principle A water extract from silage is acidified and centrifuged. The alcohols and volatile fatty acids (VFA) are separated in the chromatography column depending on their molecular weight and then detected, identified, amplified, and areas integrated. 2. Scope The procedure for determination of alcohols and volatile fatty acids is only applicable to silages. 3….

Urea – Spectrophotometric Method

1. Principle The sample (feed or feed ingredient) is suspended in distilled water with a clarifying agent. The urea content is determined using a spectrophotometer after addition of 4-dimethylaminobenzaldehyde (4-DMAB). 2. Scope The method is suitable for feeds and forages. Some feeds have added urea as a supplemental source of nitrogen. This method describes determination…
