Dietary Fatty Acid Induction of Peroxisome Proliferator Aactivated Rreceptor Gamma PPAR gamma Gene in Broiler Chickens Elham Behdani El behdani @yahoo com octobr Department of animal Science Collage of Agriculture Isfahan University of Technology Isfahan Degree M Sc language Farsi Dr F Nourbakhsh farshid@cc iut ac ir Abstract There is a real concern in broiler chicken industry to reduce the fat content of it sproducts Therefore reduction of fat in poultry with dietary or geneticis manipulations isconsidered The objective of this study was to investigate the effects of different dietary fatsources including soybean oil SO poultry grease PG and yellow grease YG used asfat source and sex effect on expression of peroxisome proliferator activated receptorgamma a major regulator of differentiation and proliferation in adipose tissue andperformance Source of the fat had no effect on body weight gain BWG feed intake FI and feed conversion ratio FCR Level of fat had no effect on body weight gain but feedintake significantly decreased at high level of fat and feed conversion ratio was improvedat high fat diet Sex has significant effect on body weight gain feed intake and feedconversion ratio and female broilers had lower body weight gain feed intake than males Abdominal fat was dissected and collected in C Total RNA was extracted with RNXreagent from abdominal fat in d Semi quantitative reverse transcription feed conversionratio was used to show difference of expression of peroxisome proliferator activatedreceptor gamma Results showed that dietary fatty acid profile and sexual hormone canaffect expression of peroxisome proliferator activated receptor gamma and development ofbroiler abdominal fat It might be concluded dietary fat does not affect body weightgain feed intake and feed conversion ratio diet of poultry grease and soybean oil mighthave major effect on expression of peroxisome proliferator activated receptor gamma poly unsaturated fatty acid of soybean oil and long carbon chain of poultry grease have amain effect on expression of peroxisome proliferator activated receptor gamma femalebroiler are more affected by expression of peroxisome proliferator activated receptorgamma than male because estrogen is an effector for peroxisome proliferator activatedreceptor gamma Therefore dietary fatty acid profile and sexual hormone can affect ondevelopment of broiler abdominal fat
