Dietary fortification of a natural biosurfactant, lysolecithin in broiler

Responses to dietary fortification of natural biosurfactant were investigated using broiler performance, serum chemistry and carcass traits. A total of 996 day old broiler chicks (Cobb 500 strain) were weighed individually and randomly assigned into four groups and three replicates per group with 83 birds per replicate. Group I, (negative control) was fed a lower nutrient density test diet without Lysoforte Booster® (lysolecithin). While, group II, (positive control) was fed the basal diet (corn-soyabean meal based), recommended by breed catalogue without Lysoforte Booster®. However, groups III and IV were fed the negative control diet with Lysoforte Booster® at a rate of 250 and 500 g/ton of feed on top, respectively. Results showed a significant (P < 0.05) lowest final weight, lowest weight gain, poorest FCR and highest feed intake in group I in comparison to the positive control and the Lysoforte Booster® supplemented groups. The negative control also had a significant (P < 0.05) higher mortality rate compared to the Lysoforte Booster® supplemented groups. Serum metabolic profile was not significant affected by dietary fortification with lysoforte booster. There was a significant (P < 0.05) increase in dressing percent in groups supplemented with Lysoforte Booster® compared to the negative control group. However, liver indices in the Lysoforte Booster® treatments were significantly (P < 0.01) lower than the positive control group. It could be concluded that the dietary fortification of lysoforte booster can improve the broiler productivity, modify carcass quality and formulate more cheaper diets with reduced energy and amino acids without any adverse effect on broilers overall performance.
