The Ultimate Guide to Feeding Pigs: A Comprehensive Handbook for Pig Farmers

Feeding pigs correctly is crucial for their growth, health, and overall productivity. Whether you’re raising pigs for meat, breeding, or as pets, understanding their nutritional needs and how to meet them is essential. This comprehensive guide provides detailed steps and instructions for feeding pigs of all ages and stages of life.

## Understanding Pig Nutritional Needs

Pigs are omnivores, meaning they can digest both plant and animal matter. Their diet needs to be balanced to provide the energy, protein, vitamins, and minerals necessary for optimal health and growth. Understanding these basic needs is the foundation of proper pig feeding.

**Key Nutritional Components:**

* **Energy (Carbohydrates and Fats):** Provides fuel for daily activities and growth. Common sources include grains like corn, barley, wheat, and oats.
* **Protein:** Essential for muscle development, tissue repair, and overall growth. Sources include soybean meal, fish meal, meat and bone meal, and synthetic amino acids.
* **Vitamins:** Necessary for various bodily functions, including immune system support and metabolic processes. Pigs require vitamins A, D, E, K, and B-complex vitamins. Commercially available vitamin premixes can ensure adequate intake.
* **Minerals:** Crucial for bone development, enzyme function, and overall health. Key minerals include calcium, phosphorus, sodium, chloride, potassium, magnesium, iron, zinc, manganese, copper, iodine, and selenium. Mineral supplements or mineral-fortified feeds are often necessary.
* **Water:** Absolutely essential for all bodily functions. Pigs should have access to clean, fresh water at all times.

**Nutritional Requirements Based on Life Stage:**

* **Suckling Pigs (Birth to Weaning):** Primarily rely on sow’s milk. Creep feed (a supplemental feed for piglets) should be introduced around 1-2 weeks of age to help them transition to solid food. Creep feed should be highly palatable and easily digestible.
* **Weaned Pigs (Weaning to 40-50 lbs):** Require a high-protein, easily digestible diet to support rapid growth. Starter feeds are specifically formulated for this stage.
* **Growing Pigs (40-50 lbs to Market Weight):** Protein requirements gradually decrease as they approach market weight. Grower and finisher feeds are designed to meet these changing needs.
* **Breeding Sows (Gestation and Lactation):** Gestating sows need a balanced diet to support fetal development. Lactating sows require a high-energy, high-protein diet to produce milk for their piglets. Specific gestation and lactation feeds are available.
* **Boars:** Boars require a balanced diet to maintain their health and fertility. A diet similar to that of gestating sows is generally appropriate.

## Step-by-Step Guide to Feeding Pigs

This guide provides detailed instructions for feeding pigs at different stages of life. Always consult with a veterinarian or animal nutritionist to determine the specific needs of your pigs, as these can vary depending on breed, environment, and individual health.

### 1. Preparing for Feeding

**a. Determine Pig Age and Stage:**

* Accurately identify the age and stage of life of your pigs (suckling, weaned, growing, breeding). This is crucial for selecting the appropriate feed.

**b. Select the Appropriate Feed:**

* Choose commercially available pig feeds specifically formulated for the pig’s age and stage of life. These feeds are typically available as starter, grower, finisher, gestation, and lactation feeds. Read the feed label carefully to understand its nutritional composition and feeding instructions.
* Alternatively, if you prefer to formulate your own feed, consult with a veterinarian or animal nutritionist to ensure that the diet meets the pig’s nutritional requirements. This is a complex process that requires careful calculation and ingredient selection.

**c. Calculate Feed Requirements:**

* The amount of feed a pig needs depends on its age, weight, and stage of life. Commercially available feed labels typically provide feeding guidelines. As a general rule:
* **Suckling Pigs:** Provide creep feed ad libitum (free choice) starting at 1-2 weeks of age.
* **Weaned Pigs:** Feed 3-5% of their body weight per day, divided into multiple feedings.
* **Growing Pigs:** Gradually increase feed intake as they grow, typically 2-3% of their body weight per day.
* **Breeding Sows (Gestation):** Feed 4-6 lbs of gestation feed per day, adjusting based on body condition.
* **Breeding Sows (Lactation):** Feed 12-15 lbs of lactation feed per day, adjusting based on litter size and milk production.
* **Boars:** Feed 4-6 lbs of a balanced diet per day.
* Adjust feed amounts based on the pig’s body condition. Overweight pigs should be fed less, while underweight pigs should be fed more.

**d. Gather Feeding Equipment:**

* You will need appropriate feeding equipment, such as:
* **Feeders:** Choose feeders that are appropriate for the size and number of pigs. Ensure that the feeders are clean and in good repair.
* **Waterers:** Pigs should have access to clean, fresh water at all times. Automatic waterers are a convenient option.
* **Scales:** A scale is useful for weighing pigs and measuring feed.
* **Storage Containers:** Use airtight containers to store feed and protect it from moisture and pests.

**e. Ensure Cleanliness:**

* Cleanliness is essential for preventing disease. Clean feeders and waterers regularly to prevent the growth of bacteria and mold. Store feed in a clean, dry place to prevent spoilage.

### 2. Feeding Suckling Pigs (Birth to Weaning)

**a. Focus on Sow’s Milk:**

* For the first 1-2 weeks of life, piglets primarily rely on their mother’s milk. Ensure that the sow is well-fed and healthy to produce adequate milk.

**b. Introduce Creep Feed:**

* Around 1-2 weeks of age, introduce creep feed to piglets. Creep feed is a supplemental feed that helps piglets transition to solid food.

**c. Choose a Palatable Creep Feed:**

* Select a creep feed that is highly palatable and easily digestible. Look for creep feeds that are formulated with ingredients like milk products, soybean meal, and corn.

**d. Offer Creep Feed Ad Libitum:**

* Provide creep feed ad libitum (free choice) in a shallow dish or creep feeder. Place the creep feeder in an area where the piglets can access it easily, but the sow cannot.

**e. Monitor Piglet Intake:**

* Monitor the piglets’ creep feed intake. Initially, they may only consume small amounts. As they get older, they will gradually increase their intake.

**f. Provide Fresh Water:**

* Ensure that piglets have access to fresh, clean water. Small waterers or nipple drinkers can be used.

### 3. Feeding Weaned Pigs (Weaning to 40-50 lbs)

**a. Transition Gradually:**

* Weaning is a stressful period for piglets. Transition them to solid food gradually to minimize stress and digestive upset.

**b. Use Starter Feed:**

* Feed weaned pigs a starter feed specifically formulated for their age and weight. Starter feeds are typically high in protein and easily digestible ingredients.

**c. Feed Multiple Times a Day:**

* Feed weaned pigs multiple times a day (3-4 times) to encourage intake and prevent digestive problems.

**d. Provide Adequate Space:**

* Ensure that weaned pigs have adequate space at the feeder. Overcrowding can lead to stress and reduced feed intake.

**e. Monitor Growth and Health:**

* Monitor the pigs’ growth and health closely. Watch for signs of illness, such as diarrhea, lethargy, or reduced appetite.

**f. Adjust Feed Intake:**

* Adjust feed intake based on the pigs’ growth rate and body condition. Underweight pigs should be fed more, while overweight pigs should be fed less.

**g. Provide Clean Water:**

* Ensure that weaned pigs have access to clean, fresh water at all times.

### 4. Feeding Growing Pigs (40-50 lbs to Market Weight)

**a. Transition to Grower and Finisher Feeds:**

* As pigs grow, gradually transition them from starter feed to grower and finisher feeds. Grower feeds are typically fed until the pigs reach approximately 150 lbs, while finisher feeds are fed until they reach market weight.

**b. Adjust Protein Levels:**

* Protein requirements gradually decrease as pigs approach market weight. Grower and finisher feeds are formulated with lower protein levels than starter feeds.

**c. Feed Based on Body Weight:**

* Feed growing pigs approximately 2-3% of their body weight per day. Adjust feed intake based on their growth rate and body condition.

**d. Provide Adequate Feeder Space:**

* Ensure that growing pigs have adequate feeder space to prevent competition and stress.

**e. Monitor Growth and Health:**

* Monitor the pigs’ growth and health regularly. Weigh them periodically to track their progress.

**f. Provide Clean Water:**

* Ensure that growing pigs have access to clean, fresh water at all times.

### 5. Feeding Breeding Sows (Gestation and Lactation)

**a. Gestation Feeding:**

* During gestation, sows need a balanced diet to support fetal development. Feed them a gestation feed at a rate of 4-6 lbs per day, adjusting based on their body condition. Avoid overfeeding, as this can lead to obesity and farrowing problems.

**b. Lactation Feeding:**

* During lactation, sows require a high-energy, high-protein diet to produce milk for their piglets. Feed them a lactation feed at a rate of 12-15 lbs per day, adjusting based on litter size and milk production. Provide plenty of water to support milk production.

**c. Monitor Body Condition:**

* Monitor the sows’ body condition throughout gestation and lactation. Adjust feed intake as needed to maintain a healthy body condition score.

**d. Provide Adequate Feeder Space:**

* Ensure that sows have adequate feeder space to prevent competition and stress.

**e. Provide Clean Water:**

* Ensure that sows have access to clean, fresh water at all times.

### 6. Feeding Boars

**a. Balanced Diet:**

* Boars require a balanced diet to maintain their health and fertility. A diet similar to that of gestating sows is generally appropriate.

**b. Feed 4-6 lbs per Day:**

* Feed boars 4-6 lbs of a balanced diet per day, adjusting based on their body condition and activity level.

**c. Monitor Body Condition:**

* Monitor the boars’ body condition regularly. Avoid overfeeding, as this can lead to obesity and reduced fertility.

**d. Provide Adequate Feeder Space:**

* Ensure that boars have adequate feeder space to prevent competition and stress.

**e. Provide Clean Water:**

* Ensure that boars have access to clean, fresh water at all times.

## Alternative Feeding Strategies

While commercial pig feeds are the most common and convenient option, there are alternative feeding strategies that can be used, particularly for small-scale or pasture-raised pigs.

**1. Pasture-Based Feeding:**

* Pigs can graze on pasture, which provides them with a source of fiber, vitamins, and minerals. However, pasture alone is not sufficient to meet their nutritional needs, especially for growing pigs and breeding sows. Supplement pasture with grain, protein sources, and mineral supplements.

**2. Kitchen Scraps:**

* Pigs can be fed kitchen scraps, but it’s important to be careful about what you feed them. Avoid feeding them meat scraps, bones, or spoiled food. Ensure that the scraps are properly cooked to kill any harmful bacteria. Kitchen scraps should only be a small part of the pigs’ overall diet.

**3. Forage Crops:**

* Pigs can be fed forage crops such as alfalfa, clover, and rye. These crops provide them with a source of fiber, vitamins, and minerals. Forage crops can be grazed or harvested and fed as hay or silage.

**4. Locally Sourced Feeds:**

* Consider using locally sourced feeds, such as grains, soybeans, and other agricultural byproducts. This can reduce feed costs and support local farmers. However, it’s important to ensure that the feeds are of good quality and meet the pigs’ nutritional needs.

## Common Feeding Mistakes to Avoid

* **Underfeeding:** Underfeeding pigs can lead to stunted growth, poor health, and reduced productivity.
* **Overfeeding:** Overfeeding pigs can lead to obesity, which can cause a variety of health problems, including lameness, reproductive problems, and reduced lifespan.
* **Feeding Inappropriate Feeds:** Feeding pigs feeds that are not formulated for their age and stage of life can lead to nutritional deficiencies and health problems.
* **Lack of Clean Water:** Pigs need access to clean, fresh water at all times. Dehydration can lead to a variety of health problems.
* **Dirty Feeders and Waterers:** Dirty feeders and waterers can harbor bacteria and mold, which can cause illness.
* **Sudden Changes in Diet:** Sudden changes in diet can cause digestive upset and reduced feed intake. Transition pigs to new feeds gradually.

## Tips for Optimizing Pig Feeding

* **Monitor Body Condition:** Regularly assess the body condition of your pigs and adjust feed intake as needed to maintain a healthy body condition score.
* **Provide Adequate Feeder Space:** Ensure that pigs have adequate feeder space to prevent competition and stress.
* **Feed Multiple Times a Day:** Feeding pigs multiple times a day can encourage intake and improve feed efficiency.
* **Provide Clean Water:** Ensure that pigs have access to clean, fresh water at all times.
* **Prevent Feed Waste:** Minimize feed waste by using appropriate feeders and managing feed storage properly.
* **Consult with a Nutritionist:** If you’re unsure about how to feed your pigs properly, consult with a veterinarian or animal nutritionist.
