What is the term for all feed consumed in a 24 hour period, which contains all the needed nutrients in the proper proportions and amounts?

The term that accurately describes all feed consumed in a 24-hour period, which contains all the necessary nutrients in the right proportions and amounts, is a balanced ration. A balanced ration is specifically formulated to meet the nutritional needs of the animal, ensuring that it receives the essential vitamins, minerals, proteins, fats, and carbohydrates required for optimal health and performance.

Using the term "balanced" emphasizes the importance of proportion and composition. A balanced ration takes into account the specific dietary requirements of different animal species and even individual animals based on their life stage, health status, and production goals.

The other terms provided do not capture this comprehensive and precise aspect of nutrition. A complete feed may refer to a product that includes all required nutrients, but it doesn't necessarily account for the specific amounts and proportions consumed in a full day's intake. Mixed feed might simply refer to a combination of various ingredients without ensuring balanced nutritional content. Supplemented feed indicates that additional nutrients are added to a basic diet, but without the assurance that the complete daily needs of the animal are being met through balance. Therefore, balanced ration is the most accurate term in this context, encapsulating the idea of all consumed feed serving the animal's nutritional requirements effectively over a 24-hour period.
