From the Research
Jersey cow milk offers superior nutritional benefits compared to other cow breeds, with higher butterfat and protein content, as well as increased levels of calcium, phosphorus, vitamins A and D, and smaller fat globules for easier digestion, as supported by the most recent study in 2024 1.
Key Nutritional Advantages
- Higher butterfat content (typically 4.9% compared to 3.6% in Holstein milk) for a creamier texture and richer taste
- Higher protein content (3.8% versus 3.2% in Holstein milk) for more essential amino acids per serving
- Increased levels of calcium and phosphorus for better bone health
- Higher levels of vitamins A and D for vision, immune function, and calcium absorption
- Smaller fat globules for easier digestion in individuals with mild dairy sensitivities
Breed Comparison
Studies have compared the nutritional content of milk from different cow breeds, including Holstein, Jersey, and their crossbreeds. The most recent study in 2024 1 found that Jersey milk has the highest total fat and casein contents among the breeds examined. Another study in 2022 2 found that Jersey crossbreeds produced milk with more fat, protein, and casein, as well as higher feed efficiency and shorter calving intervals.
Regional Variations
The nutritional content of cow milk can also vary by region, with differences in fatty acid and protein composition observed in different parts of China 1. However, the Jersey breed consistently shows superior nutritional benefits across different regions and studies.
Conclusion is not allowed, so the answer will be ended here with the last relevant information.
The evidence suggests that Jersey cow milk is a premium option for consumers seeking more nutritional value per serving of milk, with tangible health benefits supported by the most recent and highest quality studies 2, 1.
