GROUVEN’S FEEDING STANDARD

• In 1859 Grouven, a German chemist published his feeding standard with crude protein, carbohydrates and fat contained in the feed as the basis of the standard.
• According to this standard a cow weighing 1,000 lbs. should be fed 28.7 lbs. of dry matter containing 2.67 lbs. of crude protein 0.6 lb. of crude fat and 14.55 lbs. of crude carbohydrates.
• Very soon after standard of Grouven, Henneberg and Stohmann found that the total nutrient contained in a feed did not form an accurate guide to its value.
• The proportion of digestible parts varied with different feeds and hence the digestible nutrient would be more valuable.
• So due to this defect Grouven’s feeding standard was abandoned.
