Quality

Milling oats are received on the basis of grain physical quality including hectolitre weight, free groats, screenings and moisture. Growers should check prices of particular varieties with potential buyers to determine the most profitable cropping options.

Many of the physical characteristics of milling and feed oats are similar, however large differences exist in some of the desired chemical characteristics. These are important with regard to suitability of varieties for milling or feed, where requirements for each industry may be significantly different. For example, milling requirements call for higher levels of B-glucans and lower oil percent, while oats for animal feed need lower levels of B-glucans and higher oil percent.
