HYDROLYZED LECITHIN IMPROVES BROILER PERFORMANCE
Dietary supplementation with Olus®Digest improves production performance in broilers, due to the emulsifying properties and metabolic effects of lysolecithins (hydrolyzed lecithin). Supplementation of broiler diets with 500 g Olus®Digest/t improves the dietary energy value by 50 to 65 kcal/kg. Using this energy matrix makes it possible to lower the dietary energy concentration without loss of performance. Moreover, due to its emulsifying capacity, fat digestion is less dependent on the intestinal health status of the birds.
This experiment was designed to evaluate the effect of Olus®Digest on production performance in broilers, under ‘commercial’ conditions.
Materials & methods
- 400 male Ross 308 broilers (starter weight 42.8 g) were distributed over 16 floor pens (25 birds/pen) placed in the middle of a commercial broiler house to mimic normal health and climate challenges, and get a more realistic estimate of the effects of Olus®Digest on production performance. Wood shavings were used as bedding material.
- A 3-phase corn/wheat/soya diet was used:
- Starter, 0-14 days
- Grower, 15-28 days
- Finisher, 29-35 days of age.
- In the starter and the grower diet, Salinomycin was used as anticoccidial. No anticoccidial was used in the finisher phase. 1.25% PKFAD was present in all diets. Soya oil and palm oil were added as dietary fat source, to reach a total dietary fat content of 5.1, 5.2, and 5.6% in the starter, grower and finisher diets, respectively.
- Treatments: Birds from the control group were fed the basal diets as such, whereas the treatment group received the same basal diet, but with 500 g Olus®Digest/t added on top.
- Measurements: Production performance parameters (body weight gain, feed intake, feed conversion ratio and mortality) were measured per phase.
- Feed and water were ad libitum available.
Results
Production performance during the 35-day production period is given in the table.
*FCRc: FCR corrected for the average body weight (0.02/100 g BW)
The effect of dietary supplementation with Olus®Digest numerically stimulated body weight gain by 27 g or 1.1% over the full 35-day period. Feed intake was not affected, and FCRc was improved by 2.0 points (P< 0,10) in broilers fed diets where low to moderate levels of added fat (max. 2.1%) were used.
Comparing the efficiency of feed utilization per phase, the effect of Olus®Digest was especially clear during the finisher phase where an improvement by 4.8 points was observed. This confirms that lysolecithin has a stronger effect on energy utilization, compared to protein, resulting in improved feed efficiency when added on top of the diet.
Conclusion
Supplementation of broiler diets with 500 g Olus®Digest/t stimulated body weight gain by 1.1% and improved feed conversion ratio by 2.0 points. The diets used contained low to moderate levels of added fat. The effect of feed conversion ratio was especially clear in the final phase from 28 to 35 days of age, where a 4.8 points FCR improvement was found.
