Understanding the Terminology
New pig buyers often encounter terms like weaner, feeder, and finisher without a clear explanation of what they actually mean. Understanding these growth stages helps you choose the right starting point for your goals, budget, and available time before market weight.
What Is a Weaner Pig?
A weaner pig, sometimes called a weanling, is a young pig that has just been separated from its mother, typically between three and eight weeks of age and weighing around 10 to 20 pounds. Weaner pigs require the most careful management since their immune systems and digestive tracts are still developing.
What Is a Feeder Pig?
A feeder pig is older and more established, typically eight to ten weeks old and weighing 40 to 60 pounds, having already made the transition to solid feed successfully. Feeder pigs are generally hardier and easier for beginners to manage since they’ve cleared the riskiest early growth stages.
Pros and Cons of Starting with Weaners
Buying weaner pigs is typically cheaper per pound and gives you more control over the entire growth process, but it also means a longer commitment and more risk during the vulnerable early weeks. Weaners need a carefully managed diet transition and extra attention to prevent scours and other early health issues.
Pros and Cons of Starting with Feeders
Feeder pigs cost more upfront but come with less risk and a shorter path to market weight, generally reaching 250 to 280 pounds within four to six months of purchase. For first-time pig owners, starting with feeder pigs is often the more forgiving choice.
Making the Right Choice for You
If you’re experienced and want maximum control over the growth process, weaner pigs offer more flexibility and lower purchase costs. If you’re new to pigs or want a shorter, more predictable path to market weight, feeder pigs are usually the safer bet.
