Ropin’ the Web
When you are talking nutrition and feeds with your feed salesperson, livestock nutritionist, veterinarian or neighbour, it is important that you both speak the same language and understand what the other person means.
You will find this list of common meanings of feed terms helpful when you are talking nutrition, reading articles, feed analysis reports or feed tags.
Acid Detergent Fibre (ADF) – the fibrous, least-digestible portion of roughage. ADF consists of the highly indigestible parts of the forage, including lignin, cellulose, silica and insoluble forms of nitrogen. Roughages high in ADF are lower in digestible energy than roughages that contain low levels of ADF. As ADF levels increase, digestible energy levels decrease.
