6 alternative protein sourcesto soybean meal

摘要

Soybean meal, containing 44 perce crude protein, remains the most common protein source for all compound feeds for pigs, poultry and dairy cattle, worldwide. It is not only readily available on a global basis but also is priced so that any other protein source cannot easily compete with soybean meal. This position of eminence has not been attained easily and without considerable cost. Perhaps another protein source could easily have taken the position of soybean if it was cultivated at such extent while strong marketing forces promoted it on a global basis. In the end, soybean meal is the textbook protein source by which example or typical formulas are formulated for educational purposes, and one that remains the reference standard for all other protein sources.
