Effect of Emulsifier Supplementation on Production Performance of Broilers in Grower Phase (0–21 days)

This trial was performed to investigate the impact of supplementation of emulsifier on broiler production parameters, nutrient digestibility, and carcass characteristics during the grower phase. To execute the trial, day-old (n=240) broiler chicks (Ross-308) were classified into 4 dietary treatments (LS0, LS15, LS30, and LS45) at random, with 6 replicates and 10 birds per replicate. Dietary treatment LS0 included a basal diet without any emulsifier; LS15 contained 150 g/ton emulsifier, LS30 contained 300 g/ton emulsifier, and LS45 contained 450 g/ton emulsifier. Weekly feed consumption and weight gain (WG) records were kept to calculate the feed conversion ratio (FCR). Birds’ feces were sampled replicate-wise on the 21st day to measure nutrient digestibility by adding Celite® as an external marker. On the 21st day, two birds from each replicate were slaughtered to evaluate carcass characteristics (percentage of dressing, carcass, and relative organ weight). During week 1, no significant (p > .05) difference in feed intake (FI) was observed among all the treatments. During the second and third weeks, the highest (p < .05) FI was observed in birds fed the LS0 diet. Birds fed LS45 showed significantly higher (p < .05) WG during all 3 weeks. During the first week, birds fed LS30 and LS45 showed similar FCRs. During the second and third weeks, better (p < .05) FCR was seen in birds fed the LS45 diets. The findings showed the highest (p < .05) crude protein, dry matter, and ether extract digestibility in birds given diet LS45. Moreover, the dressing, carcass, thigh yield, and relative heart and liver weight percentages were higher (p < .05) in birds fed LS45 diets than in other dietary treatments. Birds fed the LS0 diet showed the highest (p < .05) relative gizzard weight percentage compared to other treatments. However, breast yield and abdominal fat weight percentages were unaffected (p > .05) due to dietary treatments. Overall, based on the outcomes of this investigation, it is suggested that supplementing the diet with emulsifier at 450 g/ton optimizes the growth performance, carcass parameters, and nutrient digestibility of nutrients of broilers throughout the grower phase (0–21 days).
