Abstract
The objective of the current study was to check the effect of fat types and polyglycerol polyricinoleate (PGPR) levels in broiler diets on broilers performance. For this purpose, three sources of fat {soy oil (SO), poultry oil (PO), and oxidized oil (OO) (oxidized soy oil)} and four levels of PGPR were used in a 3×4 factorial arrangement. The trial had 12 different dietary treatments: (T1) basal ration (BR) containing SO without PGPR supplementation, (T2) BR containing PO without PGPR supplementation, (T3) BR containing OO without PGPR supplementation, (T4) BR containing SO with PGPR supplementation (0.025%), (T5) BR containing PO with PGPR supplementation (0.025%), (T6) BR containing OO with PGPR supplementation (0.025%), (T7) BR containing SO with PGPR supplementation (0.035%), (T8) BR containing PO with PGPR supplementation (0.035%), (T9) BR containing OO with PGPR supplementation (0.035%), (T10) BR containing SO with PGPR supplementation (0.045%), (T11) BR containing PO with PGPR supplementation (0.045%), (T12) BR containing OO with PGPR supplementation (0.045%). Results revealed that interaction was present for fat sources and PGPR levels in the current experiment (p<0.05) for feed conversion ratio, body weight, dry matter (DM) and crude fat (CF) digestiblities (p<0.05). In overall trial, interaction results of PGPR and fat sources showed that performance of birds and nutrient digestiblities of DM and CF was increased in birds received diet contained SO and PGPR @ 0.35%. It is concluded that PGPR @ 0.035% could be successfully used in broiler ration contained soy oil to improve the performance.
Highlights
In commercial broiler diets, vegetable oils and animal fats are being used to improve the growth rate and feed efficiency (Blanch et al, 1996; Tavárez et al, 2011; Zhang et al, 2011)
Several researchers reported that addition of external emulsifiers in the diet of broilers improves fat digestibility and growth rate of broiler (Emmert et al, 1996; Huang et al, 2007; Zaefarian et al, 2015; Zhang et al, 2011; Zhao et al, 2015)
The selection of external emulsifier is critical and depends upon the fat sources used in the broiler diet
Summary
Vegetable oils and animal fats are being used to improve the growth rate and feed efficiency (Blanch et al, 1996; Tavárez et al, 2011; Zhang et al, 2011). Several researchers reported that addition of external emulsifiers in the diet of broilers improves fat digestibility and growth rate of broiler (Emmert et al, 1996; Huang et al, 2007; Zaefarian et al, 2015; Zhang et al, 2011; Zhao et al, 2015). Different types of emulsifiers are being used in the diet of poultry to enhance fat digestibility, growth rate, feed efficiency and meat quality (Emmert et al, 1996; Huang et al, 2007; Zaefarian et al, 2015; Zhang et al, 2011; Zhao et al, 2015). Upadhaya et al (2017) used ‘Tween 20’ with an HLB value of 12 in the ration of broilers
