title: The effects of a novel synthetic emulsifier product on growth performance of chickens for fattening and weaned piglets.
abstract: Two experiments were conducted to evaluate the effects of a novel synthetic emulsifier product (AVI-MUL TOP) on the growth performance of chickens for fattening and weaned piglets. The emulsifier product consists of 50% vegetal bi-distillated oleic acid emulsified with 50% glyceryl polyethyleneglycol ricinoleate. In experiment 1, 480 1-day-old female Cobb500 chickens for fattening were assigned to two treatments: (1) a control diet (CTR); and (2) the control diet+the emulsifier (AMT, 1 g/kg from day 0 to day 10, 0.75 g/kg from day 10 to day 20 and 0.5 g/kg from day 20 to day 34 of the trial). AMT supplementation increased BW on days 20 and 34 (P<0.01). Dietary AMT increased the average daily gain and average daily feed intake (ADFI) from day 10 to day 20, from day 20 to day 34 and from day 0 to day 34 (P<0.01). A reduced feed conversion ratio was observed in the AMT group from day 10 to day 20 (P<0.01). In experiment 2, 96 Stambo HBI×Dalland piglets were weaned at 24 days and assigned to two treatments (the basal diet without the product (CTR) or with 2 g/kg emulsifier from day 0 to day 14 and 1.5 g/kg from day 14 to day 42 (AMT)). There was an increase in the ADFI associated with AMT supplementation from day 14 to day 42 (P=0.04). These results indicated that supplementation with the synthetic emulsifier may significantly improve the growth performance of chickens for fattening and numerically improve that of weaned piglets.
