Hypothesis
Dietary RPG supplementation could optimize lactating dairy cows’ production performance and health.
Conclusion
RPG supplementation at 450 g/day improves milk production, quality, and metabolic health in early lactating cows.
Supporting Evidence
- Final body weight increased with RPG supplementation, especially at 450 g/day.
- Milk yield and energy-corrected milk were significantly greater in supplemented groups.
- Milk lactose and solids-not-fat contents increased significantly with RPG supplementation.
- Blood glucose levels rose, while non-esterified fatty acids and β-hydroxybutyric acid concentrations decreased.
Takeaway
Feeding cows a special type of glucose helps them produce more milk and stay healthy after giving birth.
Methodology
The study involved 32 early-lactation Holstein Friesian cows divided into four groups, each receiving different levels of RPG supplementation over a 42-day trial.
Limitations
Potential for higher RPG dosages to induce insulin resistance.
Participant Demographics
Early-lactation Holstein Friesian cows, average 6 days in milk.
