2 trials in growing-fattening pigs were performed
1. A first trial was performed in Lima (Peru) in collaboration with a local university. Results showed an increased performance when supplying the nutritional emulsifier in an energy reduced (-50 kcal/kg) diet (corn-soy, soybean oil). The body weight (BW) in the treatment group significantly surpassed (+1.52%) the BW of the control and the FCR was
numerically improved. Although a rather conservative energy reduction was applied, the economical evaluation showed a 4.53% increase in profit per animal.
2. A second trial was performed under practical conditions in The Philippines. Here, results showed the benefit of putting the nutritional emulsifier on top. The final weight (at day 140) was significantly (p<0.01) increased by 6.65 kg and the FCR was reduced to 2.22 compared to the control (2.44), resulting in a big benefit for the farm owner.
Aquatic species, focus on tilapia
Focusing on improvement of the fat and nutrient digestibility of fish species a trial was executed at the Mahasarakham University (Thailand) on Nile tilapia. Results showed that the supplementation of the nutritional emulsifier improved body weight gain (p < 0.05) and feed conversion ratio (p < 0.05).
The liver malondialdehyde (MDA) content, a measure of oxidative stress, was significantly decreased (P < 0.05) in the treatment group. The tested nutritional emulsifier improved metabolisable energy (AMEn) and fat digestibility in fish diets. There was a correlation with the oil level in the diet. These results suggest that dietary nutritional emulsifier supplementation can improve the digestion and absorption capacity of lipids, which might be the reason for the observed improvement in growth performance.
Positive effects of nutritional emulsifiers
The positive effect of nutritional emulsifiers has been well established in broilers, both in practice and in scientific literature. The extensive research project set up by Orffa shows also the positive effects of the nutritional emulsifier, Excential Energy Plus, in other animal species. Looking at the economical side of things, the following return-on- nvestment (ROI) can be seen for laying hens (3:1), turkeys (3:1) and growing-fattening pigs (7:1). Orffa is committed to further increase the knowledge on their nutritional emulsifier, Excential Energy Plus, in different diets and different animal species.
