Effect of Fat Sources and Emulsifier Levels in Broiler Diets on Performance, Nutrient Digestibility, and Carcass Parameters

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.

Influence of Thermally Oxidized Vegetable Oil and Animal Fats on Growth Performance, Nutrient Digestibility, Carcass Parameters and Meat Quality of Broilers

The current study was planned to investigate the influence of soy oil, oxidized soy oil, poultry oil single refined and poultry oil double refined on the performance of broilers chicken. A total of two hundred and forty, day-old broiler chicks were divided into 4 treatments in such a way that each treatment had six replicates and each replicate had ten chicks. The experimental treatments were separated with the usage of single refined poultry oil, double refined poultry oil, oxidized soy oil and soy oil in the diet of broilers. In both starter and overall periods average body weight was higher (p 0.05) for birds which were on a basal diet containing soy oil as compared to other diets. Similarly, feed intake was higher (p 0.05) for birds which were on a basal diet containing soy oil in the starter phase. In the overall phase, average body weight was less in oxidized oil as compared to other dietary treatments (p 0.05). Similarly, birds showed poor feed conversion ratio in the basal diet that contained oxidized oil (p 0.05) in the overall phase of the experiment. The birds showed better digestibility (p 0.05) for crude fat on a basal diet containing vegetable oil and double refined poultry oil as compared to other diets. Results showed no effects of experimental treatments on the meat quality and carcass parameters (p>0.05). Therefore, it can be concluded that poultry single refined and double refined oil could be a possible substitute for fresh soy oil for better performance as compared to oxidized soy oil.

Effect of Fat Sources and Emulsifier Supplementation in Broiler Starter, Grower and Finisher Diets on Performance, Nutrient Digestibility, and Carcass Parameters

The purpose of this study was to evaluate the effect of fat sources and emulsifier supplementation in different phases on growth performance of broilers. Treatments were; (T1) basal ration (BR) which contained soy oil (SO) and had inclusion of emulsifier for whole life, (T2) BR which contained poultry fat (PO) and had inclusion of emulsifier for whole life, (T3) BR which contained oxidized oil (OO) and had inclusion of emulsifier for whole life, (T4) BR which contained SO and had inclusion of emulsifier during starter phase (T5) BR which contained PO and had inclusion of emulsifier during the starter phase, (T6) BR which contained OO and had inclusion of emulsifier during the starter phase, (T7) BR which contained SO and had inclusion of emulsifier during the starter phase (T8) BR which contained PO and had inclusion of emulsifier during the grower phase, (T9) BR which contained OO and had inclusion of emulsifier during the grower phase, (T10) BR which contained SO and had inclusion of emulsifier during the finisher phase, (T11) BR which contained PO and had inclusion of emulsifier during the finisher phase (T12) BR which contained OO and had inclusion of emulsifier during the finisher phase. The Basal ration which contained SO and supplemented emulsifier during the grower phase and throughout life increased the body weight gain. The supplementation of emulsifier in the finisher phase and throughout life in a diet which contained SO had better feed conversion ratio. The supplementation of emulsifier in the finisher phase and throughout life in SO based diet increased the dry matter and crude fat digestibility. We recommend emulsifier supplementation in the finisher phase for the economic point of view.
