The protein percentage may be the first number you notice on a bag of chicken feed—but it cannot tell you the whole nutritional story.

In this Audio Edition, Rip Stalvey, Carey Blackmon and livestock nutritionist Jeff Mattocks examine the vitamins, minerals and metabolizable energy that help determine how well poultry use their feed.

The conversation explains why minimum nutrient requirements are not necessarily optimum levels, how vitamins support vision, feather development, reproduction and normal immune function, and why minerals must remain in balance rather than being added individually without a plan.

You’ll also learn:

• Why vitamin A matters to feathers, skin, vision and developing chicks
• How vitamin E and selenium work together
• What B vitamins may contribute to normal behavior and stress response
• Why vitamin C can be useful during heat stress—but difficult to add correctly
• How heat, air and long storage can reduce vitamin value
• Why excess minerals can interfere with one another
• The relationship among calcium, phosphorus and other minerals
• What metabolizable energy means on a practical level
• Why growing birds need different energy levels at different stages
• How to begin evaluating a poultry feed tag more thoughtfully

This discussion is intended to help poultry keepers ask better questions about feed. It is not a recommendation to add individual vitamins or minerals without knowing the complete diet. More is not automatically better, and some nutrients can become harmful when overused.
