Why Starter Nutrition Matters
The first few weeks after weaning are one of the most important periods in a pig’s life with weaning happening most commonly around 21-28 days old. During this transition, piglets shift from a milk-based diet to solid feed while going through the stress of weaning. How pigs are fed during this phase has a lasting impact on growth rate, feed efficiency, and overall health.
When starter nutrition is inadequate, piglets may experience reduced feed intake, digestive upsets, and slower early weight gain; all of which can affect performance long after the nursery phase.
Understanding the Weaning Transition
Weaning introduces several challenges at once:
· A sudden change in diet form and nutrient composition
· Increased exposure to environmental stress
· Adjusting to new feeding and watering systems
Because of these changes, starter feeds must do more than meet basic nutrient requirements. They must encourage intake, support gut development, and help pigs adapt smoothly to solid feed.
Key Nutritional Priorities in Pig Starter Feeds
Highly Digestible Energy
Piglets have limited digestive capacity immediately after weaning. Starter feeds should supply energy from easily digestible sources that support growth without overwhelming the digestive system.
Quality starter feeds typically include:
· Easily digestible milk proteins
· Processed or cooked grains
· Added fat sources for calorie density
· Controlled fiber levels to maintain gut function
Balanced Protein and Amino Acids
Protein is essential for muscle development and early growth, but balance is critical. Starter feeds should provide highly digestible protein sources along with the correct amino acid profile to support efficient growth and minimize digestive stress.
Lysine, methionine, and threonine play key roles during this stage and should be supplied in adequate amounts through the starter ration.
Supporting Gut Health
Digestive health plays a major role in how well pigs transition after weaning. Starter feeds formulated with gut-supporting ingredients help stabilize digestion and reduce the risk of scours.
These may include:
· Acidifiers to support stomach pH
· Prebiotics or probiotics to encourage beneficial bacteria
· Yeast-based ingredients to support fiber digestion
Using a Step-Down Feeding Approach
Many successful feeding programs use a phased starter approach:
· Early starter feeds encourage intake before and immediately after weaning
· Intermediate starters help pigs adapt to grain-based diets
· Transition feeds prepare pigs for grower rations
Management Practices That Support Starter Feed Success
Feed quality and management work together. To maximize results:
· Offer fresh feed multiple times per day and remove any stale or spoiled feed
· Keep feeders adjusted to allow easy access without excess waste
· Ensure constant access to clean, unfrozen water
· Keep pens clean and free from manure build-up
· Maintain warm, dry, draft-free housing
Early feed intake is one of the best indicators of future performance.
Common Starter Feed Mistakes to Avoid
· Transitioning to grower feed too early
· Inconsistent feeding times and amounts
· Making frequent feed changes
· Ignoring water intake
· Not monitoring feed intake to identify any possible disease or injuries
Consistency and patience are essential during the starter phase.
