What is the role of goat milk in neonatal nutrition?

Goat Milk in Neonatal Nutrition: Not Recommended for Infants Under 12 Months

Goat milk is not recommended for neonatal nutrition and should not be used as a substitute for breast milk or infant formula for infants under 12 months of age due to significant health risks including iron deficiency, excessive protein load, and inadequate nutritional composition. 1

Current Guidelines on Infant Nutrition

The Centers for Disease Control and Prevention (CDC) explicitly discourages the use of goat's milk for infants under 12 months, stating it should not be used as a substitute for breast milk or infant formula 1. The nutritional hierarchy for infant feeding is clear:

1. First choice: Exclusive breastfeeding for the first 4-6 months of life
2. Second choice: Iron-fortified commercial infant formula
3. Not recommended: Unmodified animal milks (including goat milk) before 12 months

Nutritional Inadequacies of Goat Milk for Neonates

Goat milk has several nutritional deficiencies that make it unsuitable for infant feeding:

• Iron deficiency risk: Goat milk has low iron content and bioavailability, increasing the risk of iron deficiency anemia in infants 2
• Excessive protein load: The high protein content places unnecessary strain on immature kidneys 1, 3
• High mineral content: Creates an excessive solute load for neonatal kidneys 3
• Folate deficiency: Goat milk has inadequate folate levels needed for rapid infant growth 2
• Improper nutrient balance: Unmodified goat milk doesn't meet the specific nutritional requirements of infants 2, 3

Potential Risks of Goat Milk for Neonates

Using unmodified goat milk in neonatal nutrition carries several risks:

• Nutritional deficiencies: Particularly iron and folate deficiencies that can impact neurodevelopment 1, 2
• Kidney stress: The high protein and mineral content creates excessive renal solute load 3
• Allergic cross-reactivity: Goat milk is not less allergenic than cow's milk due to protein cross-reactivity 1, 2
• Infectious risks: Raw goat milk carries pathogen risks 3

Goat Milk in Commercial Infant Formula

While unmodified goat milk is unsuitable for infants, properly formulated goat milk-based infant formulas have been developed:

• The European Food Safety Authority has stated that proteins from goat's milk can be suitable as a protein source for infant formula, provided the final product complies with compositional criteria laid down in regulatory directives 2
• Commercial goat milk infant formulas are fortified to address nutritional inadequacies 4
• Clinical trials have shown that properly fortified goat milk formula provides growth and nutritional outcomes in infants that do not differ from those provided by standard whey-based cow milk formula 5

Special Considerations for Preterm and Vulnerable Infants

For preterm infants and other vulnerable neonates, the recommendations are even more stringent:

• Mother's expressed milk provides the best short- and long-term health benefits for very low birth weight infants, including improved neurodevelopment 6
• When mother's milk is unavailable, pasteurized donor human milk is the next best option 6
• Specialized commercial formulas designed for preterm infants should be used when human milk is not available

If Goat Milk Must Be Used (Not Recommended)

If despite all recommendations goat milk must be used (which is strongly discouraged), the following modifications are essential but still insufficient to make it a suitable infant food 3:

• Pasteurization or boiling to eliminate pathogens
• Dilution to reduce solute load
• Vitamin fortification, particularly folate
• Iron supplementation
• Professional medical supervision

Conclusion

Human milk is the gold standard for infant nutrition, providing optimal nutrition with the highest percentage of bioavailable iron and numerous bioactive components that support neurodevelopment 6, 1. Commercial infant formulas are specifically designed to meet the nutritional needs of infants when breastfeeding is not possible 1.

Unmodified goat milk should not be used in neonatal nutrition due to significant nutritional inadequacies and health risks. While properly formulated and fortified goat milk-based infant formulas may be suitable alternatives to cow milk-based formulas, they should only be used under medical supervision when breastfeeding is not possible.
