Cows can eat lemons in small amounts, but lemons are not a good feed. Citrus is very acidic, and whole fruit can be a choking hazard. Dried citrus pulp is a common cattle feed ingredient, but fresh lemons should be an occasional, cut-up treat at most.
Are lemons safe for cows?
Lemons are not poisonous to cattle, but they are not very nutritious and can cause problems in large amounts:
- Acidity: A cow’s rumen works best at a near-neutral pH. A lot of acidic fruit can upset rumen function and contribute to digestive problems.
- Choking: Whole lemons, oranges and similar round fruits can lodge in a cow’s throat. Cut fruit into pieces if you feed it.
- Peel oils: The peel contains strong aromatic oils that cows may not like and that can irritate the digestive tract in large quantities.
- Low value: Lemons are mostly water and sugar, so they do not replace hay or pasture.
Claims that citrus fruit “kills worms” or cures disease in cattle are not backed by evidence. Use dewormers and treatments as directed by your vet.
Citrus pulp is different
Dried citrus pulp is what is left after juice is squeezed and is a common feed ingredient, especially in Florida, California and Brazil. It is a fiber and energy source that works well as part of a balanced ration. If you are feeding citrus pulp, follow the supplier’s guidance and the advice of a nutritionist.
How to offer lemons safely
- Offer only fresh, clean fruit. Never feed moldy fruit.
- Cut lemons into small wedges or slices.
- Keep the amount small, such as a few slices per cow, no more than occasionally.
- Watch for drooling, reduced appetite or loose manure and stop if you see these.
Better treats for cows
Cows generally do better on treats that are closer to their natural diet, such as hay cubes, carrots, apples (cut up), pumpkin and a handful of dry oats. Read our guides to homemade treats for cows, the most nutritious snacks for cows and pumpkins for cows.
Bottom Line
A few cut-up lemon slices won’t hurt most cows, but there is no reason to make them a regular feed. Stick with forage and cattle-safe treats, and call your vet if a cow shows bloat, drooling or loss of appetite after eating something unusual.
