The difference between a well-harvested, properly baled alfalfa crop and a mediocre one can represent 3 to 5 litres of milk per cow per day, which across a 150-cow herd translates directly into the margin between a profitable season and a difficult one. Understanding the quality benchmarks that govern alfalfa hay procurement and on-farm production is essential for anyone making baling, purchasing, or feeding decisions for a dairy herd.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-854 size-large\" src=\"https:\/\/hay-balers.com\/wp-content\/uploads\/2026\/06\/Industry-Segment_-Dairy-Farming-1024x617.webp\" alt=\"\" width=\"1024\" height=\"617\" title=\"\" srcset=\"https:\/\/hay-balers.com\/wp-content\/uploads\/2026\/06\/Industry-Segment_-Dairy-Farming-980x590.webp 980w, https:\/\/hay-balers.com\/wp-content\/uploads\/2026\/06\/Industry-Segment_-Dairy-Farming-480x289.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/p>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">The Core Quality Parameters: What the Numbers Mean<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Canadian forage testing laboratories report alfalfa hay quality on a dry matter basis using several standardized parameters. Each one tells a different part of the nutritional story.<\/p>\n<h3 style=\"font-size: 1.3rem; color: #235434; margin-top: 28px; margin-bottom: 10px;\">Crude Protein (CP)<\/h3>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Crude protein is the most widely cited alfalfa quality metric. For lactating dairy cows in mid to peak production, dietary CP requirements range from 16 to 18 percent of total DM intake. High-quality Canadian alfalfa cut at early bud stage typically tests at 20 to 24 percent CP on a dry matter basis, providing a protein-dense component that can reduce or displace purchased soybean meal in the total mixed ration. Late-cut alfalfa harvested at full bloom may fall to 14 to 17 percent CP, limiting its utility in high-production dairy diets.<\/p>\n<h3 style=\"font-size: 1.3rem; color: #235434; margin-top: 28px; margin-bottom: 10px;\">Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF)<\/h3>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">ADF and NDF are the structural fiber fractions that govern digestibility and dry matter intake potential. For dairy-quality alfalfa hay, target values are:<\/p>\n<ul style=\"padding-left: 24px; margin-bottom: 18px; font-size: 1.05rem;\">\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">ADF below 31 percent<\/strong> \u2014 indicates high digestibility and energy density suitable for high-producing cows.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">NDF below 40 percent<\/strong> \u2014 supports adequate dry matter intake; higher NDF values limit gut fill capacity and reduce total DM consumption.<\/li>\n<\/ul>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">As alfalfa matures from bud to full bloom, both ADF and NDF increase substantially. A crop cut at 10 percent bloom might test at 28 percent ADF and 36 percent NDF; the same stand left to reach 80 percent bloom can test at 37 percent ADF and 50 percent NDF. The difference in milk production potential is significant.<\/p>\n<h3 style=\"font-size: 1.3rem; color: #235434; margin-top: 28px; margin-bottom: 10px;\">Relative Feed Value (RFV) and Relative Forage Quality (RFQ)<\/h3>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">RFV and RFQ are composite indices used in North American hay markets to summarize quality into a single number for buying and selling purposes. For dairy-quality alfalfa, target grades are:<\/p>\n<div style=\"overflow-x: auto; margin-bottom: 24px;\">\n<table style=\"width: 100%; border-collapse: collapse; font-size: 1rem;\">\n<thead>\n<tr style=\"background: #235434; color: #fff;\">\n<th style=\"padding: 10px 14px; text-align: left;\">Grade<\/th>\n<th style=\"padding: 10px 14px; text-align: left;\">RFV Range<\/th>\n<th style=\"padding: 10px 14px; text-align: left;\">Dairy Suitability<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Premium<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">185+<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">High-production cows, 35+ litres\/day<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Supreme<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">170\u2013185<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Mid-peak lactation cows<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Grade 1<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">151\u2013170<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Mature cows, dry period supplementation<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Grade 2<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">125\u2013150<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Heifers and dry cows only<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 9px 14px;\">Grade 3 and below<\/td>\n<td style=\"padding: 9px 14px;\">Below 125<\/td>\n<td style=\"padding: 9px 14px;\">Not recommended for lactating dairy cows<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2><\/h2>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Harvest Timing: The Single Biggest Quality Driver<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">No piece of equipment or storage technique can recover quality that was lost in the field due to late cutting. In Canadian production zones, the optimal harvest window for first-cut alfalfa is typically at 5 to 10 percent bud stage, before any flowers have opened. Second and third cuts can be harvested at similar maturity stages, though many producers target a slightly later cut in autumn to allow root carbohydrate storage before freeze-up.<\/p>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">The practical challenge is that optimal maturity for quality often conflicts with optimal yield. Waiting an additional five to seven days past early bud stage can increase yield by 15 to 20 percent but reduce CP by 3 to 4 percentage points and increase ADF by 5 to 7 points \u2014 a trade-off that costs more in reduced milk production than it gains in forage tonnage.<\/p>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Efficient cutting and conditioning equipment reduces the time between mowing and baling, shortening the window during which leaf shatter and rain damage can degrade quality. A well-adjusted mower-conditioner that adequately crimps alfalfa stems without shattering dry leaves is the first link in the quality chain.<\/p>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Moisture at Baling: The Critical Threshold for Round Bales<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Baling alfalfa at the correct moisture level is the most common point at which quality is either preserved or destroyed in the round baling system. The following guidelines apply specifically to round bale dry hay intended for Canadian dairy operations:<\/p>\n<ul style=\"padding-left: 24px; margin-bottom: 18px; font-size: 1.05rem;\">\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">Below 15 percent moisture:<\/strong> Safe for long-term storage in barn or outdoor covered rows. Leaf integrity may be compromised if the crop dried too rapidly in hot, low-humidity conditions.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">15 to 18 percent moisture:<\/strong> Acceptable range for baling with good ventilation in the storage area. Some heating will occur but typically remains within acceptable limits.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">18 to 22 percent moisture:<\/strong> Risky range for dry hay. Significant heating, potential mold development, and DM losses up to 10 to 15 percent are possible. Consider wrapping as baleage if above 20 percent.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">Above 22 percent moisture:<\/strong> Do not store as dry hay. These bales require immediate plastic film wrapping and treatment as fermented baleage to prevent catastrophic spoilage.<\/li>\n<\/ul>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Investing in a reliable in-field moisture probe is one of the best decisions a dairy forage producer can make. Guessing moisture at baling by feel or visual inspection leads to inconsistent results and periodic storage losses that are entirely preventable.<\/p>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Bale Density and Its Effect on Storage Quality<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">A well-formed, tight round bale of alfalfa hay sheds rain more effectively, reduces the surface-to-volume ratio exposed to oxidation, and maintains internal temperature more consistently during storage. Loose, poorly formed bales from under-powered balers or from operating at excessive ground speed absorb more rainfall, heat unevenly, and develop mold pockets in low-density zones.<\/p>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">The <a style=\"color: #235434; font-weight: bold; text-decoration: underline;\" href=\"\/fr_fr\/produit\/9yg-2-24d-hay-round-baler\/\">9YG-2.24D Hay Round Baler<\/a> is designed to produce consistently dense, uniformly shaped bales across variable windrow conditions \u2014 a key attribute for alfalfa hay producers who cannot always control drying rate or windrow width between cuts. Consistent bale density is also important for tractor-mounted bale handlers and TMR mixers, where irregular bale weights disrupt ration balancing routines.<\/p>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Leaf Retention: Where Nutritional Value Lives in Alfalfa<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Alfalfa leaves contain approximately 70 percent of the total crude protein in the plant and 90 percent of the vitamins and minerals. Stems, by contrast, are high in structural fiber and low in digestible nutrients. Leaf loss of 10 to 15 percent \u2014 which is common in over-dry conditions or rough handling during raking and baling \u2014 can reduce overall hay CP by 3 to 5 percentage points.<\/p>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">To preserve leaf retention during the windrow and baling stages, experienced Canadian dairy hay producers follow these practices:<\/p>\n<ul style=\"padding-left: 24px; margin-bottom: 18px; font-size: 1.05rem;\">\n<li style=\"margin-bottom: 10px;\">Rake alfalfa at morning dew when relative humidity is above 50 percent \u2014 leaves are more pliable and less prone to shattering.<\/li>\n<li style=\"margin-bottom: 10px;\">Adjust pickup tine height carefully to minimize ground contact and soil contamination, which increases ash content and depresses digestibility.<\/li>\n<li style=\"margin-bottom: 10px;\">Run the baler at moderate forward speed \u2014 high-speed baling increases leaf shatter and produces uneven bale density.<\/li>\n<li style=\"margin-bottom: 10px;\">Use net wrap rather than twine \u2014 net wrap completes the binding cycle faster and reduces the time the bale spins with the chamber open, cutting leaf loss in the final wrapping stage.<\/li>\n<\/ul>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Hay Raking and Windrow Management for Canadian Alfalfa<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Proper windrow formation before baling directly affects how uniformly the crop feeds into the baler pickup and how consistently bales form. A <a style=\"color: #235434; font-weight: bold; text-decoration: underline;\" href=\"https:\/\/balerhay.com\/product\/9lzy-9-0-finger-type-hay-rake\/\" target=\"_blank\" rel=\"noopener\">finger-type hay rake<\/a> handles dry alfalfa with gentler tine action than rotary alternatives, reducing leaf loss during the merging step and producing windrows of more consistent cross-section that feed more evenly into the baler pickup.<\/p>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Windrow width should be matched to the baler pickup header width \u2014 typically 80 to 90 percent of the maximum pickup capacity. Windrows that are too narrow force the baler to travel at reduced speed to fill the chamber, wasting field time. Windrows that overflow the pickup sides result in crop left on the ground behind the machine and uneven bale formation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-919\" src=\"https:\/\/hay-balers.com\/wp-content\/uploads\/2026\/07\/\u725b.png\" alt=\"\" width=\"64\" height=\"64\" title=\"\" srcset=\"https:\/\/hay-balers.com\/wp-content\/uploads\/2026\/07\/\u725b.png 64w, https:\/\/hay-balers.com\/wp-content\/uploads\/2026\/07\/\u725b-12x12.png 12w\" sizes=\"auto, (max-width: 64px) 100vw, 64px\" \/><\/p>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Storage Practices That Protect Quality Through Winter<\/h2>\n<p style=\"font-size: 1.05rem; margin-bottom: 18px;\">Even perfectly baled alfalfa hay can lose 20 to 30 percent of its nutritional value in outdoor storage under Canadian winter conditions without basic protective measures. The following standards apply to round bale storage on Canadian dairy farms:<\/p>\n<ul style=\"padding-left: 24px; margin-bottom: 18px; font-size: 1.05rem;\">\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">Covered storage:<\/strong> Barn or shed storage is ideal and essentially eliminates weather-related DM losses. For round bales stored under cover, end-on stacking (with the flat bale ends facing outward) maximizes space use and allows for airflow between bales.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">Outdoor storage on gravel pads:<\/strong> Elevating bales off ground contact with a gravel pad or concrete surface reduces bottom-layer losses from 15\u201320 percent to 3\u20135 percent. A simple gravel pad costs far less than the hay lost through ground moisture absorption over a Prairie winter.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">Row orientation:<\/strong> Orient outdoor bale rows on a north-south axis to maximize solar warming and promote uniform drying of the bale surface after rain or snow events.<\/li>\n<li style=\"margin-bottom: 10px;\"><strong style=\"color: #235434;\">Spacing between rows:<\/strong> Allow at least 1 m between rows to facilitate airflow and reduce shade-related moisture buildup on the north-facing bale surfaces.<\/li>\n<\/ul>\n<h2 style=\"font-size: 1.8rem; color: #235434; border-left: 5px solid #f2c043; padding-left: 14px; margin-top: 40px; margin-bottom: 16px;\">Practical Quality Standards Summary for Dairy-Grade Canadian Alfalfa Hay<\/h2>\n<div style=\"overflow-x: auto; margin-bottom: 24px;\">\n<table style=\"width: 100%; border-collapse: collapse; font-size: 1rem;\">\n<thead>\n<tr style=\"background: #235434; color: #fff;\">\n<th style=\"padding: 10px 14px; text-align: left;\">Parameter<\/th>\n<th style=\"padding: 10px 14px; text-align: left;\">Target for High-Production Dairy<\/th>\n<th style=\"padding: 10px 14px; text-align: left;\">Acceptable for Dry Cows \/ Heifers<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Crude Protein (DM basis)<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">20\u201324%<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">15\u201319%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">ADF<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Below 31%<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">31\u201338%<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">NDF<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Below 40%<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">40\u201350%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">RFV<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">170+<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">125\u2013170<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Moisture at baling<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">Below 15%<\/td>\n<td style=\"padding: 9px 14px; border-bottom: 1px solid #ddd;\">15\u201318%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 9px 14px;\">Ash content<\/td>\n<td style=\"padding: 9px 14px;\">Below 9%<\/td>\n<td style=\"padding: 9px 14px;\">9\u201312%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div style=\"background: #235434; color: #fff; padding: 28px 32px; border-radius: 6px; margin-top: 44px; margin-bottom: 8px;\">\n<p style=\"font-size: 1.1rem; font-weight: bold; margin-bottom: 10px;\">Baling Equipment That Protects Alfalfa Quality<\/p>\n<p style=\"font-size: 1rem; margin-bottom: 16px;\">Canada Hay-Balers Co., Ltd supplies round baler equipment suited to alfalfa dry hay production across all major Canadian dairy regions.
