Effect of anti-nutritional factors of oilseed co-products on feed intake of pigs and poultry
TA Woyengo, E Beltranena, RT Zijlstra�- Animal Feed Science and�…, 2017 - Elsevier
Soybean, canola, camelina and flaxseed co-products from the oilseed industry are used to
formulate pig and poultry feeds. However, these co-products contain various anti-nutritional
factors (ANF). The major ANF in soybean and potentially co-products is trypsin inhibitor (TI).
Pigs and poultry can tolerate TI levels up to 3.00 and 4.00 TIU/mg in the diet, respectively.
Solvent-extracted soybean meal has low TI activity (< 14.0 TIU/mg); most TI is destroyed
during the desolventising-toasting stage of oil extraction. Thus, inclusion of soybean meal in�…
