Abstract

The present study investigated the effect of an emulsifier with very high hydrophilic-to-lipophilic balance (HLB) value (18) on growth performance and fat digestibility in turkeys. A total of 1120 day-old female Hybrid Converter turkeys were randomly divided into four treatment groups with 7 replicates (pens) of 40 birds each. Control group (T1) turkeys were fed a basal diet (BD), while turkeys from experimental groups received different levels of the commercial emulsifier VE added to diets with standard or reduced metabolizable energy (ME) content: T2 – BD + 500 ppm of VE; T3 – BD + 500 ppm of VE until 8 weeks of age, and 250 ppm from 9 to 16 weeks; T4 – BD – 3% ME + 500 ppm of VE until 8 weeks of age, and 250 ppm from 9 to 16 weeks. Regardless of its dietary inclusion level (500 g/ton and 500/250 g/ton feed), the emulsifier positively influenced the body weights (BW) and body weight gains (BWG) of birds. On days 56 and 112, significant differences in the values of these parameters were noted between the control treatment (T1) vs. groups T2 and T3. Emulsifier addition even contributed to an increase in the BWG and BW of birds receiving diets with 3% lower ME content, as compared with turkeys fed control diets. This shows that the emulsifier more than compensated the reduction in ME in T4. The turkeys from group T3 were characterized by significantly higher feed efficiency than T1 and T4 birds. The highest fat digestibility was noted in turkeys fed diets with a standard ME level and emulsifier addition (T2 and T3). In conclusion, the use of dietary emulsifier positively influences the growth performance of turkeys, and improves fat digestibility.
