Dietary supplementation of late pregnancy diet with yeast derivatives can influence the colostrum yield, colostrum composition and gut performances of sow

Sorry, but I think we must consider the molecules, products, by-products generated by microbioma before indicate any benefic effect in performance in piglets or sows. The food animal industry must get an alliance with other scientist who are studing DNA or micro-arrays to offer a conclusion about any supplementation.

The work seemed interesting to me from all angles, but zootechnical and health highlight more because of the increase in the volume of production of colostrum and IgG, which would give us heavier and healthy piglets.

Is soy sauce cake, i.e. by-product of Kikkoman sauce contain also consider as yeast derivatives? Please comment. Thanks.
