Choosing How Frequently to Offer Supplements

Once you’ve decided which supplements to give your horse, you’ll need to determine how frequently those supplements should be given to them.

For example, if your horse need a vitamin C supplement to boost their immune system, should they be given a vitamin C tablet once a day or once a week?

Everything is determined by their present vitamin C levels, which leads us back to the veterinarian.

Blood tests can be performed to assess the precise amounts of nutrients taken and processed into your horse’s body for active utilization.

These tests will assist you in determining whether your horse is lacking in any specific nutrient and, if so, the degree of the shortage.

When all is said and done, you can then pick supplements to satisfy those deficiency needs and have a happier and healthier horse.

Keeping Your New Horse Supplements Safe

Another consideration when purchasing horse vitamins is how you will keep them. What type of packaging does the supplement come in? How successfully does the packaging keep air out?

These are critical considerations since excessive air exposure might cause a supplement to become rancid and unusable. So, read customer evaluations and contact the selling firm to see how their bundle works.

If required, you may keep your horse supplements in a 5-gallon bucket with a lid or any comparable container to protect them from the weather.

Especially if the supplement comes in a protective container, it should not be kept outside, even if it claims to be weather resistant.

Moisture and humidity can alter the quality of a supplement product, making it less effective over time.
