Beneficial Effects of Glycerol Usage in Dairy Cows Nutrition
Puvača, Nikola | Glamočić, Dragan
This review explores the multifaceted benefits of glycerol usage in dairy cow nutrition, focusing on its impact on metabolic health, milk production, physiological and biochemical mechanisms, and broader implications for animal health, welfare, and environmental sustainability. Glycerol, a byproduct of biodiesel production, serves as an effective energy source for dairy cows, particularly during periods of negative energy balance, reducing the risk of metabolic disorders such as ketosis. It has been shown to enhance milk production by improving glucose metabolism and supporting lactation. The review also delves into the physiological and biochemical mechanisms by which glycerol influences rumen fermentation, energy partitioning, and overall cow health. Furthermore, the broader implications of glycerol supplementation, including its potential to improve animal welfare and reduce the environmental impact of dairy farming, are examined. The integration of glycerol into dairy nutrition represents a promising approach to optimizing cow health, productivity, and sustainability in the dairy industry.
