Based on prices these two products can be economical
to feed to cattle in some instances. If soybean prices fall too low
or in the case of peanuts those above and beyond the quota may have a much
lower monetary value.
The nutritional analysis of soybeans indicates that they contain approximately 20% fat, 42% protein and 90% TDN on a dry matter basis. Raw soybeans contain urease and thus should not be used in conjunction with feeds that contain urea or non-protein nitrogen. Based on their fat content, cattle should be eased onto whole soybeans so as not to induce rapid diarrhea. They should be increased up to about 5 pounds per head per day and once adapted may consume as much as 6 or 7 pounds per day. Ideally they should be coarsely ground for optimum utilization. The problem with grinding soybeans is that they are very "gummy" when processed through a hammermill. To help reduce this problem it would be prudent to mix with some corn or other feedstuff prior to grinding. Palatability is generally not a problem.
There have been recent inquiries from the southern part of the state on the value of whole peanuts in the shell as a cattle feed. The nutritional analysis is as follows: 38% fat, 24% protein and 95% TDN. As with the soybeans the limiting factor is the fat content. A maximum of about 4 pounds per day for grown cows should be recognized. Again, introduce them to the cattle in a gradual manner. Unlike the whole soybeans, the peanuts will be well utilized withour further processing. Indications are that cattle will readily consume peanuts in the shell.
