Several nutritionists have observed performance improvements and better litter conditions when they were able to replace a portion of the soybean meal with a reliable animal protein. In cold weather, this becomes a useful tool, as the non-starch polysaccharides in the soy meal, along with the high potassium level, can create stresses on the intestinal tracts. Generally, if the soymeal can be reduced in a broiler from 31% to 26% using animal protein with all amino acid balances being equal, my own observation has been that of equal-to or better performance, and drier litter.
