At what age foal can you start feeding Horse Guard?”


Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:

If the mare is receiving Horse Guard I would start the foal when you wean the foal because he is getting selenium from his mother’s milk. However, if the mare is deficient or it is an orphan foal you can supplement them right right away. Just feed the dose according to his weight. For example, if you estimate he weighs 250 when you wean him feed a 1/4 of a scoop.

      Thank you for the question. If she needs to build more muscle and still growing rapidly, I recommend Super Weight Gain. It provides the vitamin-mineral supplement, Horse Guard; a gut supplement with probiotics and live yeast cultures; and the base of the full-fat extruded soybeans which provides high levels of lysine, the first-limiting amino acid for horses and is very important for growing horses. However, if she has good muscling and she is on a high-quality hay you can put her on regular Horse Guard to meet all her micro-mineral and vitamin needs. I like to pair both products with grass and alfalfa hay to ensure their calcium: phosphorus ratio is correct. Let me know if I can answer anymore questions.
