At Irvine Creek Hay Sales & Feedneeds, we use sensory analysis to grade our hay.
We use the following criteria:
• Colour
• Smell
• Maturity
• Texture
• Weathering
• Contamination ( eg. weeds, dirt)
A combination of these factors will determine the grading. For example, a hay cut at the right time of maturity, may have some weathering factors that will downgrade it, but likely still has a better nutritional value than hay baled past maturity date.
Horses often have different criteria resulting from their nutritional needs, so a hay graded lower, can still be a good hay; green doesn’t matter as much to horses.
IRVINE CREEK FARMS sometimes takes core samples from different areas of a stack to form a representative sample to base a grade, as nutrient levels can be affected by varying soils and topography (low or high areas). We generally do not send hay out for lab analysis as this is time consuming and expensive, but customers are welcome to.
