  • Potassium
  • Phosphorus
  • Vitamin A
  • Vitamin C
  • Vitamin K

All of these above-mentioned nutrients are needed by the cows for the healthy functioning of several important functions. Here’s what these nutrients do;


Fiber is a crucial nutrient not only for humans but animals as well. The subject of this post needs fiber for a variety of reasons.

Read some Fiber-rich foods

According to recent studies, The major ones are; maintaining cow health, rumen function, and normal fattest. Moreover, it encourages chewing and saliva production.

So for all the important reasons, it is advised to have cow feed that is rich in fiber. Since tomatoes contain a good amount of fiber, the said vegetable would make a highly nutritional treat. And then tomatoes are a natural source of fiber so what’s the harm?


Cows need potassium more than anything else as a significant amount of potassium is lost through milk production.

In the period of lactation, potassium requirements doubles. Feeding potassium-rich grains, fruits, and vegetables would greatly help in overcoming the need.

The said domestic animal needs this nutrient for impressive milk production, reproductive performance, immune function, and to prevent cardiovascular disease and treat heat stress.



Phosphorus is an essential nutrient that is demanded for almost every function in the cow’s body.

However, mainly it is used in producing milk, metabolizing fats, carbohydrates, protein, building bones, and teeth.

Vitamin A

Vitamin A is a fat-soluble vitamin that must be consumed every single day.

Continuous supply is needed for proper bone formation, growth, energy metabolism, skin, hoof, epithelial tissue, and mucous membrane maintenance.

As per the experts, one average-sized tomato contains 427 mg potassium. So, there might not be any other better potassium-rich option.

Vitamin C

Cows do not require vitamin C in impressive amounts because the said animal can not synthesize ascorbic acid.

Fortunately, tomatoes do not contain enough vitamin C that would create an issue. Three or four tomatoes at a time can never be the cause of any health issues. Cows can eat oranges and apples as an alternative.

However, a small amount of vitamin C would improve rumen function and help in protecting the structural integrity of the cells of the immune system.

Vitamin K

Vitamin K is needed for one important reason; the production of prothrombin. Adequate prothrombin prevents blood clotting and internal bleeding.

So if a fruit or vegetable, satisfying the taste buds, is playing it’s part in fulfilling a part of the need, it’s a win-win.
