What is the Difference Between Whole Corn and Cracked Corn?
Whole corn is the entire corn kernel, intact and unprocessed, while cracked corn is simply whole corn kernels that have been coarsely broken into smaller pieces. This seemingly minor difference impacts their uses, nutritional value, and even how animals digest them.
The Grain of Truth: Understanding Whole and Cracked Corn
Corn, Zea mays, is a staple grain around the world, feeding both humans and animals. While we often think of corn on the cob or sweet corn, dried corn kernels, processed in various ways, form the basis of many products. Among these, whole corn and cracked corn stand out as basic forms with distinct applications. What is the difference between whole corn and cracked corn? Understanding this difference is crucial for farmers, livestock owners, and anyone interested in animal feed or grain processing.

Whole Corn: Nature’s Original Package
Whole corn represents the corn kernel in its most natural, unprocessed state. It consists of:
- The pericarp: The outer layer, providing fiber and protection.
- The endosperm: The largest part, containing primarily starch and some protein.
- The germ: The embryo, rich in oils, vitamins, and minerals.
Whole corn requires significant chewing and processing by animals to break down the kernel and access the nutrients within.
Cracked Corn: Simplicity and Accessibility
Cracked corn is precisely what its name suggests: whole corn kernels that have been broken, or cracked, into smaller pieces. This is usually achieved through a milling process using rollers or hammer mills. The key characteristic is the coarse texture – the kernels are not ground into flour.
The main advantage of cracked corn is increased digestibility, particularly for animals with less robust digestive systems, such as poultry, younger livestock, or older animals with weakened teeth. The cracking process exposes more surface area, making it easier for digestive enzymes to break down the starch and access the nutrients.
Nutritional Showdown: Whole Corn vs. Cracked Corn
The nutritional profiles of whole corn and cracked corn are virtually identical. The primary difference lies in bioavailability, or how easily the nutrients can be absorbed and utilized by the body.
| Nutrient | Whole Corn (per 100g) | Cracked Corn (per 100g) |
|---|---|---|
| —————– | ———————- | ———————– |
| Calories | ~365 | ~365 |
| Protein (g) | ~9.4 | ~9.4 |
| Carbohydrates (g) | ~74.3 | ~74.3 |
| Fat (g) | ~4.7 | ~4.7 |
| Fiber (g) | ~7.3 | ~7.3 |
While the total nutrient content remains the same, the digestibility of cracked corn is superior, especially for animals. The broken kernels make it easier for digestive enzymes to access and break down the starch, allowing for better nutrient absorption.
Uses and Applications: Where Each Shines
-
Whole Corn:
- Long-term storage (less susceptible to spoilage due to intact pericarp).
- Animal feed, particularly for larger livestock like cattle.
- Ethanol production (fermentation process can handle whole kernels).
- Corn mazes and decoration.
-
Cracked Corn:
- Poultry feed (chickens, ducks, etc.).
- Bird feeding (attracts a wider variety of birds).
- Pig feed (easier to digest than whole corn).
- Bait for fishing or trapping.
- Some brewing applications.
Storage Considerations: Preserving Quality
Both whole corn and cracked corn require proper storage to prevent spoilage. Key factors include:
- Moisture Control: Keep both grains dry to prevent mold growth and insect infestation.
- Pest Control: Store in sealed containers to prevent access by rodents and insects.
- Temperature: Store in a cool, dry place to slow down degradation.
While whole corn generally has a slightly longer shelf life due to its intact pericarp acting as a protective barrier, cracked corn can still be stored effectively with proper management.
Cost Comparison: Finding the Best Value
The cost difference between whole corn and cracked corn typically isn’t significant. The price of cracked corn may be slightly higher due to the additional processing step of cracking the kernels. However, factors like location, supply and demand, and bulk purchasing can all influence the price. When evaluating cost-effectiveness, consider the needs of your animals. If you’re feeding poultry, cracked corn is often worth the slight price increase due to its improved digestibility. For larger livestock, whole corn might be more economical.
Making Your Own Cracked Corn: A DIY Approach
While commercially produced cracked corn is readily available, you can make your own at home using a grain mill or even a heavy-duty blender. Ensure the corn is thoroughly dry before processing. The goal is to crack the kernels into coarse pieces, not to grind them into flour. Be cautious when using equipment, and follow manufacturer’s safety instructions.
Frequently Asked Questions (FAQs)
Is cracked corn just cornmeal?
No, cracked corn is not cornmeal. Cornmeal is ground into a fine powder, while cracked corn consists of coarsely broken kernels. The texture and intended uses are very different. Cornmeal is used for baking, while cracked corn is primarily used as animal feed or bait.
Is cracked corn good for deer?
Cracked corn is a common and readily available food source for deer, particularly in areas where natural food is scarce. However, some wildlife experts caution against relying solely on corn, as it may not provide a balanced diet and can contribute to digestive issues if consumed in excessive quantities. A balanced diet is crucial for deer health.
Can humans eat cracked corn?
While humans can technically eat cracked corn, it’s not a common food source. Its coarse texture makes it less palatable than other corn products like cornmeal or polenta. If you were to consume it, you would want to cook it thoroughly to soften it.
Does cracked corn attract rats?
Yes, cracked corn can attract rats and other rodents. Its readily available carbohydrate content makes it a desirable food source. Storing cracked corn properly in sealed containers and cleaning up any spills are essential to prevent attracting unwanted pests.
How long does cracked corn last?
The shelf life of cracked corn depends on storage conditions. Properly stored cracked corn can last for several months. However, it’s susceptible to mold and spoilage if exposed to moisture. Inspect it regularly for any signs of spoilage before feeding it to animals.
What are the benefits of feeding cracked corn to chickens?
Cracked corn is a popular and affordable feed for chickens. Its smaller particle size makes it easier for them to digest, especially for chicks and younger birds. It also provides a good source of energy.
Is whole corn or cracked corn better for turkeys?
Cracked corn is generally preferred over whole corn for turkeys, particularly for younger birds. The smaller pieces are easier for them to consume and digest. Mature turkeys can eat whole corn, but cracked corn is still a more accessible and efficient energy source.
Can cracked corn make animals sick?
Cracked corn can make animals sick if it’s moldy or contaminated. Always inspect the corn for signs of spoilage before feeding it to animals. Additionally, feeding an excessive amount of corn without a balanced diet can lead to nutritional deficiencies.
What’s the difference between yellow corn and white corn, and does it affect the difference between whole and cracked?
The primary difference between yellow and white corn is their color and some subtle differences in their carotenoid content. Yellow corn contains beta-carotene, which is a precursor to Vitamin A. This color difference doesn’t fundamentally change the difference between whole and cracked corn; both yellow and white corn can be processed into either form, with the same digestive and usage implications.
Can I grind whole corn to make cracked corn?
Yes, you can grind whole corn to make cracked corn. A grain mill or even a high-powered blender (used carefully) can be used to break the kernels into smaller pieces. Just be sure to crack the kernels coarsely rather than grinding them into a fine powder.
What animals benefit most from cracked corn?
Animals with smaller or less developed digestive systems benefit the most from cracked corn. This includes poultry (chickens, ducks, turkeys), smaller birds, and young livestock (calves, piglets). It’s easier for them to digest and extract the nutrients from the broken kernels.
Does cracking corn reduce its nutritional value?
No, cracking corn does not significantly reduce its nutritional value. The nutritional content (protein, carbohydrates, fat, fiber) remains essentially the same. The benefit of cracking the corn is that it makes those nutrients more bioavailable – easier for animals to digest and absorb.
