Effect of Different Emulsifiers on Growth Performance, Intestinal Histology and Serum Biochemistry in Broilers Reared on Different Fat Sources

The main objective of this research study was to evaluate the efficacy of different emulsifiers on growth performance, intestinal histology and serum biochemistry in broilers reared on different fat sources. A 2 x 4 experiment using 2 oil sources (soybean oil (SO) and refined poultry oil (RPO)) and 4 emulsifiers (control, lysolecithin, lysophospholipid and bile acids) was undertaken using factorial arrangement under completely randomized design using Minitab 17. One thousand, three hundred and sixty (1360) day-old broiler birds (ROSS-308) were divided into eight treatments having five replicates (34 birds in each). Feed intake and body weight were recorded in order to calculate FCR. Two birds from each replicate were randomly selected and slaughtered to collect ilium samples. Use of soybean oil in broiler diet had improved (P0.05) by oil sources. Weight gain, feed consumption and FCR were improved (P
