Piglet hydration plays a vital role in supporting young pigs during one of the most stressful periods of their lives — weaning. Yet, water access is often overlooked in early-stage housing. This blog explains why drinker size and mounting height matter, how they affect performance, and what to look for when choosing a hydration setup for young pigs..
Water is essential for every system in a piglet’s body — from digestion and nutrient absorption to body temperature regulation. During the first few days post weaning, piglets face a sharp drop in feed intake. Without enough water, their digestive system slows, and they struggle to maintain performance.
Fresh water encourages early feed consumption, helping to keep piglets hydrated and their gut health stable during this high-stress period. The AHDB water factsheet offers additional insights into the role of water across all livestock systems..
Piglets have smaller mouths, weaker jaw pressure and less coordination than older pigs. If the drinker is mounted too high or has a fast flow rate, piglets may not be able to drink comfortably. This can result in low water intake, reduced feed consumed and slower growth.
Key risks include:
A well-positioned, appropriately sized drinker supports the weaning transition by promoting early and regular drinking behaviour. For example, low-mounted nipple drinkers with adjustable height or shallow troughs allow nursery piglets to access water with ease, improving overall water consumption.
Piglet performance is directly influenced by both water and feed. A reduction in water flow or poor access can impact feed intake by as much as 25%. If piglets don’t drink, they won’t eat — and if they don’t eat, their development stalls.
Several factors affect this relationship:
One waterer per group is not always enough. Providing sufficient drinking points ensures that competition doesn’t limit access, especially in larger pens or mixed-weight groups.
During the days post weaning, stress levels are high. Piglets are adjusting to new surroundings, unfamiliar pen mates, and solid feed. Dehydration can set in quickly, and early signs are easy to miss. A good strategy includes:
Control group trials have shown that pigs drinking enough water in the first week post weaning maintain better feed conversion and show fewer symptoms of digestive stress.
At Fisher Drinkers, we offer drinkers designed specifically for pigs at all stages, including low-level nipple drinkers and hygienic trough options suitable for weaned pigs and suckling piglets alike. Our pig drinkers prioritise flow control, hygiene and durability — helping farmers provide both water and peace of mind.

Getting piglet hydration right isn’t just about avoiding problems — it’s about unlocking healthier, faster-growing pigs from day one. The right drinker size, access height and water flow all work together to support feed intake, gut development and overall performance.
If you’re looking to improve outcomes in your weaner units or creep pens, we’re here to help. Explore our pig drinkers or contact us for practical, site-specific advice on setting up your system for success
1. How much water should a piglet drink per day?
Water consumption varies with temperature, diet, and age, but on average, piglets drink between 0.3 to 1 litre per day. Ensuring piglet hydration during the first days post weaning is essential for gut health and steady feed intake.
2. What are the early signs of dehydration in piglets?
Look for signs like sunken eyes, dry mouth, lethargy, and reduced feed consumption. Dehydration in young pigs can set in quickly and affect performance within hours.
3. Can poor water flow impact piglet performance?
Yes. A flow rate that’s too fast or too slow can discourage pigs drinking regularly. Controlling water flow ensures both water and nutrients are absorbed effectively by the digestive system.
4. How does heat affect piglet hydration?
Higher temperatures increase water consumption needs. Electrolyte balance becomes more critical, especially in nursery piglets exposed to heat stress or fluctuating temperatures.
5. Should piglets receive electrolytes during weaning?
In many cases, yes. Electrolytes can help stabilise the small intestine and support hydration during the stressful post weaning period. Products containing sodium and organic acids are often used to maintain piglet performance.
6. What’s the best drinker type for piglet hydration?
Low-mounted nipple drinkers or shallow troughs work best. They allow nursery piglets to access enough water comfortably. One waterer per group may not be enough, especially in busy pens — proper setup is key to supporting piglet hydration.
