Here's a look at feed additives and how they might fit your ration and your budget.
Here's a look at feed additives and how they might fit your ration and your budget.
Feed additives are ingredients added for a non-nutrient role. (For example, sodium bicarb is added as a rumen buffering agent, not a source of sodium.) Additives vary in cost from 3 to 30 cents a cow a day. The main reason to add a feed additive is to enhance cow performance based on farm conditions, research results, the additive's role, and economic returns.
Here, I outline additives in six categories that may help you and your advisors decide if an additive should be included.
The category, current status, is classified in the following ways.
Recommended: Include as needed.
Experimental: Additional research is needed before recommending.
Evaluative: Monitor individual farm situation (there will be variable responses).
Not recommended: Currently lacks economic response.
Here are the additives mentioned in the September 25, 2010 issue of Hoard's Dairyman.
