Back to BlogUnderstanding Cattle Feed Labels: Protein, Fat, Fiber & What They Mean
Walk into any feed store in India, and you will see dozens of cattle feed bags stacked high, each printed with numbers and percentages that most farmers glance at but few truly understand. Yet these numbers — crude protein, crude fiber, total digestible nutrients, and mineral content — are the most reliable indicators of feed quality. Knowing how to read them empowers you to make informed purchasing decisions and get the best value for your money.
Crude Protein (CP): The Milk-Building Block
Crude protein represents the total nitrogen content in the feed, multiplied by 6.25 to estimate protein content. For a lactating cow producing 10 to 15 litres of milk, the concentrate feed should contain at least 18 to 20 percent crude protein. Higher-producing cows (above 20 litres) may need 22 percent or more. However, not all protein is created equal. Rumen-degradable protein (RDP) is broken down and used by rumen microbes, while rumen-undegradable protein (RUP or bypass protein) passes through to the small intestine for direct absorption. High-quality feeds like Nutricana's formulations balance both types for maximum efficiency.
Total Digestible Nutrients (TDN): The Energy Indicator
TDN measures the overall energy value of a feed. It accounts for the digestible portions of protein, fiber, fat, and carbohydrates. A good lactating cow concentrate should have a TDN of 70 to 75 percent. Feeds with TDN below 65 percent are insufficient for high-producing cattle and will cause weight loss during peak lactation. When comparing two feeds at similar prices, always choose the one with higher TDN — it delivers more usable energy per kilogram.
Crude Fiber (CF): Rumen Health Guardian
Crude fiber measures the indigestible plant cell wall components. In concentrate feeds, crude fiber should typically be below 12 to 15 percent. Too much fiber in the concentrate means less room for energy-dense ingredients. However, total dietary fiber (from concentrate plus roughage) must remain adequate — at least 17 percent acid detergent fiber (ADF) from forage — to maintain healthy rumen function and prevent acidosis.
Fat Content: Concentrated Energy
Fat provides 2.25 times more energy than carbohydrates per gram. Most compound feeds contain 3 to 5 percent crude fat. Some premium feeds include bypass fat supplements that resist rumen breakdown, delivering energy directly to the cow's metabolism. This is especially important for high-producing cows that cannot consume enough feed to meet their energy demands through carbohydrates alone.
Minerals: The Hidden Performers
Calcium, phosphorus, sodium, and trace minerals are listed on quality feed labels. Calcium should be 0.8 to 1.2 percent for lactating cows, with a calcium-to-phosphorus ratio of 1.5:1 to 2:1. Trace minerals like zinc, copper, manganese, and selenium support immunity, reproduction, and hoof health. Nutricana feeds include precisely calibrated mineral premixes so farmers do not need to purchase additional mineral supplements.
Quality Certifications: What to Look For
Look for feeds manufactured under BIS (Bureau of Indian Standards) Type-I specifications and preferably from an ISO 9001:2015 certified facility. These certifications ensure consistent ingredient quality, accurate labeling, and contamination-free production. Nutricana's manufacturing facility holds ISO 9001:2015 certification, and every batch undergoes rigorous quality testing before dispatch.
A Simple Test at the Feed Store
Compare the price per kilogram against the crude protein and TDN values. A feed costing 2 rupees more per kilogram but offering 3 percent higher protein and 5 percent higher TDN is almost always the better investment. Cheap feed with low nutrient density costs more in the long run through reduced milk production and increased health issues.
