Question:

My horse is no longer black but has turned more dark brown. What do you think this is due to, are there other causes than the common trace element imbalance between iron and copper?

Answer:

It is quite common for a horse's coat color to change over time, and it can be due to several different factors. Here are some possible causes:

1. Nutritional Imbalances

As you mentioned, imbalances in trace elements such as copper, zinc, or iron can affect coat color. Copper deficiency is particularly known to give a browner tone to black coats.

2. Seasonal Variations

The color and shine of the coat can change during shedding, winter coat changes, or sun bleaching during the summer.

3. Protein and Amino Acid Deficiency

Keratin, which makes up the coat, is formed by protein and amino acids. A deficiency in these can affect both the color and quality of the coat.

4. Health Status and Metabolism

Underlying health problems, such as hormonal imbalances or other diseases, can sometimes cause changes in coat color.

Recommendation:

To help improve your horse's coat color and overall health, I would recommend Activ Mineral. It is a complete mineral mix containing copper, zinc, and essential amino acids, which helps strengthen the coat and maintain a deeper color.
