Feeding deer isn’t as simple as dumping out bags of protein.
QUESTION: I’ve started feeding deer store-bought protein feed, but I’m looking to cut down the cost. I’m wanting to mix my own feed, but I’m not sure what is best to mix and how to calculate the nutritional factors. What would you suggest? I know genetics play a huge role in antler growth, but I’m hoping to maximize their potential with a high-protein/fat feed year round. Does feed play a big role, if so what should I feed?
ANSWER: The answer is not as simple as you might like. For starters, a deer’s dietary needs change throughout the year, so if you plan to feed year-round you might want to adjust regularly to best meet these needs.
Next, you need to determine the level of proteins and minerals in each component of your mix. The advantage of commercial deer feeds is that’s already done for you. Most blocks or loose mix deer feeds contain at least 18% protein, consisting of degradable and undegradable protein at a ratio of somewhere between 60:40 and 30:70. Better ones will also have minerals like calcium and phosphorous for tissue and bone growth.
Protein is more important in spring and summer during peak growth periods. In late summer, fall and winter, deer need more fat and carbs for energy and survival. If you can find a feed store that can advise you on these components, you may be able to save a few bucks and help your bucks grow bigger. Otherwise, I’d suggest using something designed specifically for feeding deer.
