EMULSIFICATION, AN ELEGANT WAY TO PROMOTE GROWTH
Numerous studies have shown the benefit of nutritional emulsifiers in poultry. In order to better understand their effects and application in swine, four trials were carried out by Orffa in coordination with research institutes around the world.
Emulsifiers and their function
The global usage of nutritional emulsifiers has been increasing fast in the animal feed industry due to their efficacy in improving energy and fat digestibility. Their application, “on top” or included in the formu- lation in energy reduced diets, has been extensively studied in poultry. Broiler feed is considered the larg- est market for nutritional emulsifiers today. Although fat digestion and metabolism differ among animal species, the principle remains the same. The key to absorption of fatty acids in monogastrics, ruminants and aquatic species is the formation of micelles in the intestine which are being stabilized, among others, by bile salts (which are natural emulsifiers). As the diges- tion of fat and other nutrients is never complete and a remnant can be found in the faeces, the addition of a nutritional emulsifier is therefore of interest to en- hance nutrient digestibility and improve animal per- formance.

The other monogastric, the pig Swine have a similar digestion as poultry as they are both monogastric, and therefore a similar positive ef- fect of the nutritional emulsifier can be expected. Four trials in fattening pigs were performed in coordi- nation with research institutes worldwide. The first trial (Meza et al. 2018) was performed in Lima (Peru) in collaboration with a local university. A total of 54 male pigs (Yorkshire x Landrace, 70 days old, 29.5 kg), followed for 29 days, were divided into two groups (control and treatment) of six repetitions each. Diets were corn-soy-based with added soy crude oil (1.8%). The diet in the treatment group was re- duced by 50 kcal/kg (by taking out a portion of soy crude oil) and supplemented with a nutritional emul- sifier (excential energy plus). Results showed an in- creased performance when supplying the nutritional emulsifier. The body weight (BW) in the treatment group significantly surpassed (+1.5 %) the BW of the control (p<0.05) and the FCR was numerically re- duced by 4 points. Although a rather conservative en- ergy reduction was applied, the economical evalua- tion showed a 4.53% increase in profit per animal. A second trial was performed under practical condi- tions in the Philippines. A total of 270 mix-sexed pigs (PIC CA25×410 sire, 63 days old, 17.4 kg), followed for 77 days, were divided into two groups of six repeti- tions each. Diets were corn-soy-cassava-based with added palm oil. In the excential energy plus supple- mented group, the final BW was significantly (p=0.01) increased by 6.65 kg and the FCR was reduced by 22 points (p=0.06) compared to the control (2.44). The application “on top” resulted in a big benefit to the farmer.
