Which feeding rule states that horses should be fed with a balanced approach?

The principle of feeding horses according to size and condition emphasizes the importance of tailoring their diet to meet their individual needs. This approach takes into consideration a variety of factors such as the horse's weight, age, workload, metabolic rate, and health status. By assessing these individual characteristics, a more balanced diet can be provided that ensures the horse receives adequate nutrition for maintenance, growth, performance, and overall well-being.

Incorporating this feeding rule promotes optimal health, helping to prevent issues like obesity or nutritional deficiencies. A horse that is properly fed according to its specific size and condition is more likely to perform well and maintain a healthy weight.

The other options, on the other hand, do not promote a balanced feeding strategy. Feeding only grain can lead to an unbalanced diet, lacking in essential nutrients found in hay or pasture. Feeding on weekends or whenever convenient might disrupt the horse's regular feeding schedule, which can negatively affect digestion and metabolism. Thus, feeding according to size and condition ultimately supports a responsible and health-focused approach to equine nutrition.
