Which of the following types of food is not essential in the diet of dairy animals?

Dairying is an agricultural branch that includes the breeding, raising, and use of dairy animals, primarily cows, for the production of milk and the various dairy products made from it.

Water, hay, grass, silage, and concentrate feed are just a few of the foods that dairy animals require for their health and well-being. 

Meat, on the other hand, is not required for dairy animals. Dairy animals are herbivores, meaning they can get all of their nutrients from plants and plant-based feed. Feeding meat to dairy animals would provide no nutritional benefits and could even harm their health.
