What to Feed Backyard Pigs: A Practical Guide for Homesteaders

Feeding backyard pigs well comes down to three things: a balanced base feed, safe kitchen and garden extras, and portions matched to the pig’s age and purpose. This guide walks through what to feed, what to skip, and how to adjust as the weather turns cold. It is written for hobby farmers and backyard keepers, not commercial operations.

Start With a Balanced Base Feed

Think of commercial pig feed as the backbone of the diet, and everything else as support. A complete feed labeled for the pig’s life stage already includes the protein, vitamins, and minerals a growing or breeding pig needs.

Match the feed to the pig’s stage

Starter: for young pigs, higher protein to support rapid growth.
Grower: for pigs past the nursery stage but still putting on size.
Finisher: for older market pigs nearing their finishing weight.
Sow or breeder: for breeding animals that need different mineral balance.

Check the label for a feeding range per pig per day, and adjust based on body condition. A pig that looks round but not obese, with a slight dip behind the shoulder, is generally in good shape. If ribs are sharp or the pig looks hollow, increase the ration. If it looks like a beach ball with legs, ease back.

Kitchen and Garden Scraps: What Is Safe

Pigs are famous for eating almost anything, and that reputation gets them into trouble. Many homesteaders feed surplus garden produce, dairy, and kitchen scraps. If you do, keep the scraps to a modest share of the total diet and know the risks.

Good additions in moderation

Garden vegetables such as squash, carrots, beets, and leafy greens
Windfall fruit, cut open so pigs can get at it
Bread and grain products in small amounts
Milk, whey, or yogurt from a source you trust

Keep these out of the trough

Moldy or spoiled feed, which can carry toxins
Raw meat and meat scraps, which raise disease concerns and may conflict with local rules
High-salt or heavily processed human foods
Chocolate, caffeine, and alcohol
Avocado skin and pit, and large amounts of onion or garlic
Any plant material you cannot identify

Rules on feeding food waste to pigs vary by state and sometimes by county. Check with your state agriculture department or extension office before making scraps a regular habit.

Pasture, Forage, and Seasonal Changes

Pigs are not ruminants. They cannot live on grass the way sheep or cattle can. Pasture is a bonus, not a foundation. Good pasture gives pigs something to root in, exercise, and nibble, but they still need their base feed.

Fall and winter adjustments

As the weather cools, pasture growth slows and pigs burn more energy staying warm. In many parts of the country, late fall is when you gradually increase the base feed and reduce reliance on forage. Provide a dry, draft-free shelter with deep bedding. Pigs tolerate cold well if they are dry and out of the wind, but wet and windy conditions are hard on them.

Water matters in cold weather too. Pigs will drink less if the water is icy, and that hurts digestion and growth. Check the water source daily and break ice. A heated bowl or a simple insulated setup goes a long way.

Portion Sizes and Feeding Routine by Age

Exact amounts depend on breed, frame size, and whether the pig is a pet, a breeder, or a market animal. Use the feed label as your starting point and adjust from there. Rough expectations for a growing market pig on a complete feed are a few pounds per day early on, rising to several pounds per day as the pig grows. Rather than chase exact numbers, watch the pig and adjust in small increments.

Daily routine that works

Feed at roughly the same times each day, often twice daily for growing pigs.
Provide fresh water at all times.
Offer scraps or garden extras once daily, after the base feed.
Remove leftovers before they sour, especially in warm weather.
Check condition weekly and note any change.

Feeding from a trough or a wide pan helps pigs eat together without one hogging the whole meal. If you keep more than one pig, provide enough space at the feeder so the smallest pig can get its share.

Warning Signs That Call for a Vet

Pigs are stoic and often hide illness until it is advanced. Learn what normal looks like: bright eyes, steady appetite, active rooting, and firm manure. Call a livestock veterinarian if you see any of the following.

Sudden refusal to eat or drink for more than a day
Diarrhea that lasts more than 24 hours, especially in young pigs
Vomiting, bloating, or a hard, distended belly
Limping, swollen joints, or reluctance to stand
Drooling, shaking, or trouble breathing
Any skin wounds that look infected or do not heal

Do not wait to see if it passes. A livestock vet can advise on diet changes, parasites, or infections that a feed adjustment cannot fix.

Frequently Asked Questions

Can pigs eat kitchen scraps?

In many places, yes, with limits. Keep scraps to a modest share of the diet, avoid meat and spoiled food, and check your state’s rules on feeding food waste to pigs before you make it routine.

How much should I feed a growing pig?

Start with the feeding range on your complete feed label and adjust based on body condition. Growing pigs are usually fed twice daily and need the majority of their nutrition from a balanced ration, not forage.

Do pigs need grain if they have pasture?

Yes. Pigs cannot meet their nutritional needs from grass alone. Pasture provides enrichment and some nutrients, but a complete feed or a well-formulated mix is essential.

What should I do if my pig stops eating?

Check water first, then look for signs of illness such as lethargy, fever, or diarrhea. If the pig has not eaten for a full day or shows other symptoms, call a livestock vet.

Final Thoughts

Backyard pigs do best on a simple routine: a good base feed matched to their stage, sensible extras, fresh water, and a watchful eye. Adjust with the seasons, respect local rules on scraps, and build a relationship with a livestock vet before you need one. That combination keeps a small herd healthy and keeps the keeper out of the mud more often than not.
