Some people might question how it can be that soybean meal is overpriced, while expeller soybean meal is a bargain, when a ton of expeller meal costs more than a ton of soybean meal. The reason for this is that a ton of expeller meal provides more dRUP (an extremely expensive nutrient) and more NEL (currently at historically high price) than regular soybean meal, so it is worth more. The difference in price between expeller meal and regular soybean meal is less than the difference in the value of its nutrients.
A few words of caution:
- Local market conditions can greatly influence cost of some feeds (for example, wet distillers grain will be very cheap if your farm is next to an ethanol plant). SESAME will give more accurate values if you use local prices rather than the values calculated for central Ohio.
- SESAME does not consider "non-nutrient value." A load of cottonseed contaminated with aflatoxin might be a good value based on SESAME, but it actually is worth nothing.
- Constantly changing ingredients in the diets can reduce milk production. Look for longer-term trends in the feed market rather than changing ingredients every time the price changes. For example, distillers grains are likely to be bargain-priced for a long time (but maybe not every single week), so you might want to consider them.
