Caring for cows involves understanding their dietary needs and digestive systems. This article provides an in-depth look at healthy food options for cows, drawing from expert recommendations and practical considerations for sanctuary settings.
Understanding the Bovine Digestive System
Cows are ruminants, possessing a unique digestive system that allows them to efficiently extract nutrients from roughage. This system relies on a symbiotic relationship with microbes in the rumen, which break down cellulose and hemicellulose, the primary components of fibrous plant matter. Instead of thoroughly chewing food before swallowing, cows regurgitate partially digested material (cud) to chew it further, maximizing nutrient absorption.
The Importance of Roughage: Hay and Pasture
As grazing animals, cows thrive on grass and other green plant matter, primarily obtained from pasture or hay. Providing ample access to these roughage sources is crucial for maintaining their health and well-being.
Hay Varieties and Selection
Hay forms a cornerstone of a cow's diet, especially during colder months or when pasture is limited. Common varieties include Timothy, Bermuda grass, and orchard grass, with availability depending on your location. Hay comes in different cuttings, each with varying nutritional content and physical characteristics. First cutting hay is typically coarser and better suited for healthy, mature cows, while second cutting is often richer and more appropriate for calves, pregnant or nursing cows, or those with dental issues.
Determining Hay Needs
Calculating hay requirements involves considering dry matter content, which refers to the weight of the hay after all moisture is removed. While it's possible to have hay analyzed for precise moisture content, a practical approach for non-production settings is to assume approximately 100% dry matter content. Keep in mind that this is an estimate, and factors like wastage should be considered.

Minimizing Hay Wastage
Hay wastage is inevitable, but certain feeding and storage methods can minimize it. Glenn Selk, Oklahoma State University emeritus extension animal scientist, estimates that hay wastage can range from 6% to over 20%. Using hay feeders significantly reduces waste compared to feeding hay directly on the ground.
Hay Bale Types and Feeding Strategies
Hay bales come in various shapes and sizes, including small square bales and large round bales. The choice depends on factors like the size of your cow population and available equipment. For smaller groups, wall-mounted hay racks might suffice, while larger populations benefit from free-standing feeders. When using feeders, ensure they are safe and accessible to all residents.
Feeding Frequency and Monitoring
Establish a feeding schedule based on bale type, feeder capacity, and consumption rates. While feeding enough hay to last a few days can save time, it also increases the risk of waste. Regularly monitor hay levels and adjust feeding plans as needed.
Safety Considerations
Always remove twine or wire securing hay bales before feeding, as these materials can be ingested and cause health problems. Be vigilant for foreign objects like cans or plastic in hay bales, and discard any moldy hay to prevent illness.
Proper Hay Storage
Proper hay storage is crucial to prevent spoilage and fire hazards. Store hay in a dry, well-ventilated area, protected from direct sunlight and precipitation. Avoid storing hay directly on the ground or concrete to prevent moisture absorption and mold growth.

The Benefits of Grazing
Whenever possible, provide cows with access to grazing pastures. Grazing is a natural cow behavior that provides not only essential nutrients but also mental and physical enrichment. Consult with your local cooperative extension office to determine the best cow-friendly grasses and vegetation for your area.
Supplementing with Grains and Other Foods
While grass and hay form the foundation of a cow's diet, supplementing with grains and other foods can provide additional nutrients and variety.
Grain Options
Corn, oats, and barley are popular grain choices for cows, offering carbohydrates and energy. Oats are also high in fiber, making them a beneficial addition to the diet.
Byproducts
Dairy farmers often supplement their cow’s diets with byproducts from food processing, such as citrus pulp, cottonseeds, distillers grains and hominy.
Treats and Enrichment
Treats can serve as enrichment for cows, alleviating boredom and promoting engagement.

Safe Treat Options
- Apples: Provide dietary fiber and carbohydrates, but feed in moderation.
- Carrots: An excellent source of energy, with cows able to consume a larger quantity.
- Oats: High in fiber and can be offered in various forms, such as oat-based snack bars.
- Turnips: Can be grown directly in the pasture for easy access.
- Potatoes (peels): Potato peels are a great source of nutrients.
- Pumpkins: Promote gut health and are generally easy to digest.
- Bananas: Offer essential nutrients like carbohydrates, vitamin B6, and natural sugars.
- Corn: Versatile and can be used as a core dietary staple or for enhanced grazing.
- Salt Licks: Provide essential minerals that may be lacking in grass and hay.
Treats to Avoid
Be cautious about sugary treats like candy, as they should only be offered in moderation. Always consult with a veterinarian regarding appropriate treat options and quantities.
Toxic Foods and Plants
Be aware of plants and foods that are toxic to cows and take steps to prevent them from accessing these substances. Consult with your veterinarian to learn about common poisonous plants in your region and symptoms of poisoning.
The Dairy Cow Diet
Dairy cows require a carefully balanced diet to support their health and milk production.
Total Mixed Ration (TMR)
Many dairy farms utilize a Total Mixed Ration (TMR) approach, which involves blending various feed ingredients into a homogenous mixture. This ensures that cows receive a consistent balance of nutrients in every bite.
Key Components of a Dairy Cow Diet
- Hay: Dried grass, legumes, or forage crops.
- Silage: Fermented forage made from crops like corn or alfalfa.
- Protein-Rich Grains: Corn, soybeans, barley, and wheat.
- Minerals and Vitamins: Essential for maintaining health and milk quality.
- Byproducts: Ingredients from food processing.
- Water: Crucial for hydration and milk production.
Water Requirements
Dairy cows require access to clean, fresh water at all times. Water intake varies depending on factors like size, age, lactation stage, and environmental conditions.
Addressing the Issues with Factory Farm Feed
The reliance on corn and soy in factory farm animal feed raises concerns about animal welfare and environmental sustainability. These crops could be used for human consumption, and their production often involves heavy use of pesticides and herbicides, contributing to biodiversity loss.
Holistic Herd Health
Maintaining a healthy herd requires a holistic approach that encompasses nutrition, environment, and medical care.
Key Factors for Cow Health
- Safe and clean living environment.
- Access to fresh water.
- Excellent diet.
- Prompt medical treatment when needed.
- Adequate space to roam.
- Plenty of sunshine.
Supporting Cow Happiness
Cows are social animals that thrive in herds. Providing opportunities for social interaction, exercise, and mental stimulation is crucial for their well-being.
Natural Remedies and Veterinary Care
When cows become ill, early detection and appropriate treatment are essential. Homeopathic treatments, such as garlic tincture, can be effective for minor ailments. Essential oils, such as oil of oregano and frankincense, can also be used to support cow health. However, it is crucial to consult with a veterinarian for more complex health issues.
