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.

Evaluation of a synthetic emulsifier product supplementation on broiler chicks

“…The results from the present study show that the emulsifier supplementation could improve growth performances (BW, ADG, ADFI and FCR) of broilers despite the short production system. These data are in agreement with the findings of our previous study (Bontempo et al, 2016). In the current study, the AMT supplement was mixed with feed compounds before the pelleting process, which may increase the humidity, reduce the pellet press energy consumption and improve pellet quality by modulating the moisture content during the pelleting process, consequently improving feed intake and animal performance.…”

“…Roy et al (2010) reported that supplementation of exogenous emulsifiers in diets containingmoderate quantities of added vegetable fats might substantially improve broiler performance. These results were confirmed by Bontempo et al (2016) who showed that supplementation with a synthetic emulsifier could improve growth performance of broilerchicks. Emulsifier, such as lecithin, has been reported to reduce free fatty acid absorption, probably by increasing the size of bile saltmicelles, which diffuse more slowly through the luminal water interface, hindering the delivery of free fatty acids to the absorptivecell surface (Saunders and Sillery, 1976).…”

Efficacy Evaluation of Poultry Feed Emulsifier on Performance and Nutrient Metabolism in Broiler Chicken

“…In the present study, emulsifier supplementation improved the growth performance (body weight, production index, and feed conversion ratio) of broilers. This is in agreement with the findings of previous study [8,9]. The improved growth performance in the present study might be linked to increased crude protein and fat assimilation.…”

Does the Use of Emulsifier or Lipase Improve Weight Gain and Feed Conversion in Broilers? A Systematic Literature Review and Meta-Analysis

“…However, it was harder to detect a significant effect of additives for weight gain and feed conversion when the lipid sources offered to the birds were of mixed origin. As discussed for the female subgroup, this is possibly more linked to the lower number of studies within this subgroup (Bontempo et al, 2015;Kaczmarek et al, 2015;Bontempo et al, 2018) rather than to possible differences in the mode of action of the additives as a function of lipid source.…”
