Fattening pigs.
A third trial, in Belgium, focused on the effects of ex- cential energy plus applied “on top” in West-Europe- an type diets (wheat/barley/soya). A total of 256 mix- sexed pigs (Danbred x Piétrain, 24 kg), followed for four months, were divided into two groups of eight repetitions each. Diets were supplemented with ani- mal fat (pig) and pure distilled fatty acids. In the nu- tritional emulsifier treated group, the final BW was increased by 1.04 kg and the FCR was reduced by 10 points compared to the control (2.67).When calculat- ing the economical aspect, a return on investment of 5:1 could be noted.
A fourth trial focused on the digestion of fats and en- ergy. A metabolic, double Latin square design, study was performed in Mexico with four ileal canulated barrows (25 kg, four pigs x eight diets). The animals were fed a simple diet based on corn with the addition of soybean oil or acidulated fat or animal fat (pig). For the treatment groups, excential energy plus was add-
ed. After four days of adaptation, one day of sampling was applied. Analysis of the feces revealed an in- creased fat digestion in the nutritional emulsifier groups for all fats applied. Fat digestibility was in- creased by 0.54%, 2.23% and 2.10% for soybean oil, acidulated fat and animal fat (pig), respectively (see figure).
Emulsification as a way to move forward The research project set up by orffa shows that the positive effects of nutritional emulsifiers, extensively proven in poultry, can also be replicated in swine. Orf- fa dedicates itself to engineer your feed additives now and in the future, and is strongly committed to fur- ther increase knowledge on nutritional emulsifiers in different diets and different animal species.
