Water Content of Cow and Goat Milk

Water content of cow & goat milk is:

Correct Answer: 87%

Both Cow milk (86.6% ≈ 87%) and Goat milk (86.5% ≈ 87%) contain approximately 87% water, making them very similar in water content.

Water Content of Different Animal Milks

• Cow milk: 86.6% (~87%)
• Goat milk: 86.5% (~87%)
• Camel milk: 86.5% (~87%)
• Buffalo milk: 84.2% (~84%)
• Sheep milk: 79.4% (~79%)
• Sow milk: 89.6% (~90%)

Total Solids in Cow Milk

If water = 87%, then total solids = 13%, which is composed of:

• Fat (lipid) — most variable component
• SNF (Solid-Not-Fat) = Lactose + Proteins + Ash + others

Why Other Options Are Wrong

• 84% → water content of Buffalo milk, not cow/goat milk.
• 90% → approximate water content of Sow milk (89.6%).
• 83% → not a standard value for any common milk; below buffalo water content.
