Common Livestock Water Requirements
Standard baseline estimates for quick lookup when planning trough capacity, pipeline sizing, or pasture water systems.
| Animal Type | Avg. Daily Water (Litres) | Key Considerations |
|---|---|---|
| Dairy Cow | 80 – 120 L | Increases by 4-5 L per kg of milk yield. Highly sensitive to heat stress. |
| Beef Cattle | 40 – 60 L | Dry feed (hay/grain) increases water need compared to lush pasture. |
| Sheep | 4 – 8 L | Lactating ewes or those on dry feed may require up to 10–12 L daily. |
| Pig (Sow) | 20 – 30 L | Lactating sows have the highest demand, often exceeding 30 L per day. |
| Horse | 30 – 50 L | Working horses or those in hot climates can easily exceed 60 L daily. |
Livestock Hydration FAQ
Everything you need to know about managing and estimating water intake for farm animals.
A typical adult beef cow requires about 40 to 60 litres of water per day. Dairy cows have significantly higher requirements, often needing 80 to 120 litres daily, which increases further during peak lactation and in hot weather.
As ambient temperature rises, livestock water intake increases substantially to regulate body temperature through respiration and sweating. When temperatures exceed 25°C (77°F), water consumption can increase by 20% to 50% or more compared to moderate temperatures (10-20°C).
Yes. Lactating animals require significantly more water to support milk production, which is roughly 87% water. For instance, a dairy cow may need an additional 4 to 5 litres of water for every kilogram of milk produced, on top of her baseline maintenance requirements.
While lush, fresh spring pasture can contain up to 80% moisture and contribute significantly to hydration, it is rarely sufficient to meet 100% of an animal’s daily water requirements. Free-choice access to clean, fresh drinking water must always be provided to prevent dehydration and maintain productivity.
