A trial was carried out to study if the auxinic effect of minimum quantities of aa-pools added to duck feed is due to their content in free-aa or to a possible unknown factor contained in the pool. The effects of synthetic-pooled aa. and of the same aa. obtained through chemical enzymatic lysis of animal proteins were compared. The results confirm the trend observed in previous researches with effects on live weight and slaughtering traits. No valuable difference between the effects obtained with synthetic pooled aa. and natural lysate was observed.

Abstract
A trial was carried out to study if the auxinic effect of minimum quantities of aa-pools added to duck feed is due to their content in free-aa or to a possible unknown factor contained in the pool. The effects of synthetic-pooled aa. and of the same aa. obtained through chemical enzymatic lysis of animal proteins were compared. The results confirm the trend observed in previous researches with effects on live weight and slaughtering traits. No valuable difference between the effects obtained with synthetic pooled aa. and natural lysate was observed.File in questo prodotto:
