Influence of processing of full fat soya beans included in diets for piglets

When digestibility coefficients were regressed against the levels of TIA in FFSB no relationships were observed (P > 0.05) for both trials. Thermal processing of the FFSB did not therefore affect digestibility while small intestinal structure, as expressed by VH and CD values, was not affected to any significant extent. Villus atrophy was not related to feed intake. However villi dimensions were associated with the dietary daily TIA intake. Combined results from both trials suggest that adequate inactivation of the anti-nutritional factors (ANFs) resulted in an increased VH and a lower TIA intake was associated with a higher mean VH. It is thus intake and not dietary concentration of TIA which is the major factor influencing responses.
