The cost of feeding cattle is the largest cost of dairy and beef production, but a new calculator, called "Cost of Feedstuffs Calculator," is available on the Web and allows producers to compare different feedstuffs to make the most economical choices.
"With the advent of the ethanol industry and the further processing of grain, the co-products resulting from these processes has opened up a whole new area of feed sources. But it has been a challenge for producers to compare these different feedstuffs as they can vary in dry matter, protein and energy," said Dave Seibert, U of I Extension animal systems educator.
Even a bigger problem is that the same feedstuffs from different processing plants can vary in their nutrient value.
"Also, the moisture content can vary between 10% and 60%, and some high moisture products can reach 80% moisture. It's nearly impossible for producers to come up with the cheapest sources of feedstuffs," Seibert said.
To further complicate matters, storage loss on some of these feedstuffs can range from 5% to 50% or more.
"The 'Cost of Feedstuffs Calculator' allows livestock managers, consultants, and veterinarians to compare the cost of purchasing, transporting and storage losses for different feedstuffs. The feedstuffs library includes 120 different feedstuffs comprising: 22 company co-products; 25 by-products; 5 new generation co-products; 27 forages; 11 grains; 9 crop residues; 12 silages; and 9 supplements. In addition, producers can add additional feedstuffs available on their farm," Seibert said.
Each of the feedstuffs can be compared to the default feedstuffs, which is "number two shelled corn; 44 percent soybean meal and mid-bloom alfalfa hay."
"Groups of 5, 10 or 15 different feedstuffs can be compared at one time with the feedstuffs ranked on a cost per pound of energy or cost per pound of protein," Seibert said.
