NON-TRADITIONAL MATERIALS IN POULTRY NUTRITION

Abstract

The present study was carried out at the Poultry Research Station , Poultry Department , Faculty of Agriculture, Fayoum, Cairo University. A total number of 500 unsexed one- day old Lohmman broiler chicks was used to study the effects of different sources of oil refining by-products such as a commercial soybean I sunflower oil blend , deodorizer distillated fatty acids DDF A , pitch oil PO and binar)' mixture of DDFA + PO on the productivity performance , carcass characteristics , fatty acids composition or meat, and meat quality. The following

results were obtained :

Live body weight LBW and live body weight gain (LBWG at 0-2 ,4-6 and 0-

6 weeks of age were significantly affected by the dietary sources , whereas , there was no significant difference at 2-4 and 0-4 weeks of age .The best feed intake FI and feed conversion FC obtained by feeding the control diet . During finishing period (6-7 weeks old ) feeding the control or pitch oil diets improved BW, LBWG , Fl , FC, CPC and ECR than those fed DDFA or DDFA+PO , expect FI it was higher in the control diet thim in the DDFA+PO diets. From mortality data it can be concluded that none of the tested oil sources was lethal at the different levels throughout the experimental period . The addition of different fat sources had no significant effect on slaughter characteristics and intestinal tract measurements at different ages . Carcass moisture % , CP% , EE% and ash % were significantly affected by treatment , except CP% , it was not affected by treatment at f weeks of age . Meat quality (color , texture, taste , aroma and acceptability ) was not affected by treatments at 6 weeks of age but it gave significant differences at 7 weeks of age . The present study indicated that the tvvo products deodorizer distillated fatty

acids and pitch oil can be used successfully in broiler feeds as a source of energy according to their comparative costs and availability.
