A Study on Effect of Soy Acid Oil and Crude Soy Lecithin Alone or in Combinations on Growth Performance and Nutrient Utilization in Broiler Chicken

Vencobb broiler chicks (n= 288) were allocated to 6 dietary groups with 4 replicates of 12 birds each. The group T1 was treated as control while 3% crude soy lecithin (CSL) and 2.5% soy acid oil (SAO) was supplemented in groups T2 and T3, respectively. CSL and SAO were added at a level of 2.5 of diet in ratios of 75: 25, 50: 50 and 25: 75 in groups T4, T5 and T6, respectively. The body weight at 6th week was significantly (P<0.05) higher in group T5 as compared to control. The cumulative feed intake (0–28 d) was significantly (P<0.05) higher in all other dietary treatments as compared to control. However, at the end of 6th week, no variation was observed. The apparent metabolisable energy as per cent of gross energy was significantly (P<0.05) higher in birds of group T5 as compared to T1, T3 and T6. Nitrogen balance was similar in all the groups. The effect of SAO and CSL alone or in combination did not influence Ca utilization. The retention of P was significantly (P<0.05) higher in birds fed diet supplemented with CSL and SAO in different ratios as compared to control. The addition of soy acid oil and crude soy lecithin in 50: 50 ratio at a level of 2.5% of diet resulted in better performance than any other combination or fed separately.
