Implementing the Strategy: A Step-by-Step Guide

Let's break down this strategy into manageable steps, like a piglet's first day of school.

1. Step 1: Early Complementary Feeding – Teach your piglets to eat like pros. Start introducing solid food around 5-7 days old, so they're ready to party on the food front.
2. Step 2: Gradual Weaning – Weaning isn't a sprint; it's a marathon. Slowly reduce the time with the sow and the number of feedings, while increasing the solid food. Think of it as a dance, not a dash.
3. Step 3: Remove the Sow, Keep the Piglets – Let the piglets stay in their original pen for 3-7 days after weaning to get comfortable in their new home. It's like giving them a cozy blanket in a new room.
4. Step 4: Reduce Milk Feed in Lactating Sows – A little hunger can be a good thing. Start reducing the sow's feed 3-5 days before weaning to encourage the piglets to eat more solid food.
5. Step 5: Maintain Consistency – Keep the same feed and pen for the first three days to a week after weaning. It's like giving them a familiar song at a dance party.
6. Step 6: Vaccination – Protect your piglets by vaccinating them against diseases like swine fever. It's like giving them a superhero cape in the fight against illness.

Creating a Comfortable Environment

Your piglets need a cozy nest. Here's how to make their environment diarrhea-proof:

• Temperature – Keep the temperature around 25°C to 27°C for 3-4-week-old piglets. It's like a warm hug on a cold day.
• Humidity – Aim for a relative humidity of 60% to 70%. Too dry or too wet, and your piglets might feel like they're in a sauna or a desert.
• Sanitation – Clean the pens regularly and disinfect them. It's like giving them a spa day to keep them happy and healthy.

When Medication is Needed

Antibiotics can be a lifesaver, but use them wisely. They're like a superpower, but with great power comes great responsibility.

Condition	Feature	Prevention
Bacillus dysenteriae diarrhea	Bloody diarrhea within the first 7 days	Examine the sow and disinfect the pen
Hyperglycemia	Common in weak piglets unable to nurse properly	Carefully manage the sow's milk quality
