In the video “When Is My Horse Considered a Senior?” by Buckeye Nutrition, Dr. Nettie Liebert, the senior equine nutrition manager for Mars Horse Care US & Buckeye Nutrition, discusses the common question of when a horse is considered a senior. She explains that this can vary depending on the individual horse, but typically some physiological changes occur around the age of 20. These changes may involve exercise capacity, hormonal fluctuations, or markers of inflammation in the body. Dr. Liebert introduces Danny, a 22-year-old horse in great shape despite not having any teeth. She emphasizes the importance of regular veterinary check-ups and explains that while senior feeds cater to the needs of older horses, any horse could benefit from the additional fiber and quality protein found in these specialized feeds.

In the video “When Is My Horse Considered a Senior?” by Buckeye Nutrition, Dr. Nettie Liebert, the senior equine nutrition manager for Mars Horse Care US & Buckeye Nutrition, addresses the question of when a horse is classified as a senior. Age alone is not the sole determinant, as horses age as individuals, but around the age of 20, there are often noticeable physiological changes associated with aging. Dr. Liebert illustrates this with Danny, a 22-year-old horse in excellent condition despite not having any teeth. She emphasizes the importance of maintaining regular contact with a veterinarian and explains that while senior feeds are designed with older horses in mind, they can also benefit horses of any age due to the increased fiber and quality protein they provide.

Defining Senior Horses

As horses age, they go through various physical and physiological changes. Determining when a horse is considered a senior depends on individual factors. Generally, by the time a horse reaches around 20 years old, there are certain age-related changes that can be observed, such as changes in exercise capacity, hormonal changes, and inflammatory markers in the body. However, these changes may not always be visible and may require measurement by a veterinarian.

Common Physical Changes in Senior Horses

Senior horses experience a range of physical changes that can impact their overall well-being. One significant change is a decrease in exercise capacity. Older horses may not be able to maintain the same level of activity or intensity as they did when they were younger. Hormonal changes also occur, which can affect the horse’s behavior and overall health. Inflammatory markers in the body may increase, leading to chronic inflammation and potential health issues.

Visible Signs of Aging in Horses

There are several visible signs of aging in horses. One common change is a change in body shape, often resulting in a more rounded appearance. Muscle loss is also commonly observed in senior horses, as the aging process naturally leads to a decrease in muscle mass. Additionally, changes in weight can occur, with some horses gaining weight and others losing weight. These visible signs can help horse owners recognize and address the changing needs of their senior horses.

Oral Health and Aging in Horses

Dental health is crucial for senior horses. As horses age, they may experience dental issues such as tooth loss, gum disease, and worn or broken teeth. These issues can make it difficult for horses to chew their food properly, leading to potential malnutrition. It is essential for horse owners to regularly have their senior horses’ teeth examined and address any dental issues promptly. Dental problems can have a significant impact on the equine diet and overall health.

Dietary Needs of Senior Horses

The dietary needs of senior horses change as they age. Older horses often require adjustments in their diet to meet their changing nutritional requirements. One option is to introduce hay-free diets, as some senior horses may have difficulty chewing and digesting hay. Instead, soaked cubes and pellets can be offered as an alternative. These soaked feeds provide the necessary fiber and nutrients while being easier for senior horses to consume and digest.

Specific Needs of A Senior Horse

Addressing top-line and muscle loss is vital for the overall health of senior horses. Regular exercise and targeted workouts can help maintain muscle mass and prevent further loss. Hormonal changes can also play a significant role in the aging process of horses, and it is important to monitor and manage these changes accordingly. Extra care and attention should be given to senior horses, including regular veterinary check-ups and wellness exams.

Recognizing Aging Signs in Horses

The signs of aging can vary among horses. Some horses may show signs of aging in their late teens, while others may not exhibit significant changes until their late 20s. It is crucial for horse owners to stay in touch with their veterinarians and have regular wellness exams to monitor their horses’ aging process. Veterinarians are trained to assess various factors, such as dental health and physical condition, to gauge a horse’s age accurately.

Transitioning to Senior Feeds

Deciding when to transition a horse to senior feeds depends on individual needs. There isn’t a specific age at which a horse must switch to a senior feed. The composition of senior feeds is designed to meet the nutritional requirements of older horses. They are formulated to be easier to chew and contain ample fiber and quality protein. However, senior feeds can also be beneficial for horses of all ages, as the nutritional needs they address are relevant to all horses.

Misconceptions About Senior Feeds

Contrary to popular belief, senior feeds are not exclusively for senior horses. The formulation of senior feeds addresses specific nutritional needs that may be beneficial for horses of various ages. Before making the switch to a senior feed, considerations such as the horse’s overall health, weight, and activity level should be taken into account. Understanding the formulation of senior feeds and consulting with a veterinarian can help horse owners make informed decisions regarding their horse’s nutrition.


Senior horses undergo significant physical and physiological changes as they age, and it is essential to address their specific needs. Proper nutrition and care play a vital role in maintaining the health and well-being of senior horses. Regular veterinary check-ups, dental care, and appropriate dietary adjustments can help senior horses lead happy and comfortable lives. The individual aging process should be carefully observed and catered to for the best outcomes in senior horse care.
