Effect of exogenous emulsifier (Glycerol polyethylene glycol ricinoleate) in energy reduced diet on carcass characteristics and visceral organ weight in broilers

Abstract

The study examined the impact of exogenous emulsifier on carcass characteristics. One hundred twenty eight day-old broiler chicks were divided into four groups: a control group (T1) fed a standard diet prepared following Bureau of Indian Standards (2007) [2] and three experimental groups receiving 350 ppm of exogenous emulsifier with energy reduced basal diet with energy reduced (- 60 kcal), (- 90 kcal), (- 120 kcal) in T2, T3 and T4 respectively and each treatment was divided into four replicates containing eight birds each. Results showed significant enhancements in dressing percentage, breast yield, drumstick yield and abdominal fat and no significant enhancement was observed in thigh yield and no significant difference in relative weight of heart, liver, proventriculus and gizzard.
