Alfalfa Quality Guide \u00b7 Leaf Retention \u00b7 All 9YF Models<\/p>\n
Alfalfa leaves contain 70\u201375% of the plant crude protein in a typical cutting. A 10% leaf loss reduces your hay crude protein by 6\u20137 percentage points \u2014 the difference between premium-grade horse hay and second-grade livestock hay at the same market. Every leaf that stays on the bale is protein that reaches the buyer. Every leaf on the ground is revenue lost before the wagon is loaded.<\/p>\n

Alfalfa leaves are not simply a cosmetic quality indicator. They are the primary repository of crude protein, total digestible nutrients and beta-carotene in the plant. The stem, while providing energy through its soluble carbohydrate content, is proportionally much lower in protein than the leaf \u2014 and the stem-to-leaf ratio changes with maturity, with later-cut alfalfa carrying a higher stem proportion and therefore lower crude protein per tonne even before any leaf loss occurs.<\/p>\n
A typical early-bloom alfalfa cutting in good condition contains approximately 20\u201322% crude protein at the time of cutting. Of this, approximately 70\u201375% resides in the leaf fraction. A 10% leaf loss \u2014 visible as shattered leaves on the windrow surface after raking \u2014 reduces the bale crude protein to approximately 14\u201315%. In premium horse hay markets where buyers pay based on crude protein grade, a reduction from 20% to 14% crude protein moves the hay from a premium category to a discount category \u2014 potentially reducing the sale price per bale by 25\u201340%.<\/p>\n
Quantifying this loss: on a 100-acre cutting producing 250 bales per acre at $12 per bale premium grade, a 10% leaf loss that reduces grade to $7 per bale represents $125,000 in lost seasonal revenue from a single cutting. The investment required to prevent leaf loss \u2014 earlier raking time, moisture monitoring, slightly lower pickup speed \u2014 is negligible compared to this revenue protection.<\/p>\n

Leaf loss and bale heating pull in opposite directions: the drier the hay at baling, the less heating risk \u2014 but the more brittle the leaves and the greater the leaf shatter loss. The wetter the hay at baling, the better the leaf pliability and the less shattering \u2014 but the greater the heating and mold risk in storage. The optimal moisture window for minimum combined loss \u2014 leaf loss plus heating damage \u2014 is 14\u201317% core moisture at the time of baling.<\/p>\n
