THE EFFECT OF Sauropus androgynus EXTRACT AND LEMURU OI ON FAT DEPOSITION AND FATTY ACID COMPOSITION OF MEAT IN BROI ER CHICKENS

Abstract

The present study as conducted to evaluate the effect of Sauropus androgynus (katuk)leaves extract (SAE)and lemuru fish oil (LO)on fat deposition and fatty acid composition of meat in broiler chickens.One hundred and fifty six broiler chickens ere distributed to 13 treatment groups ith 3 cages in each treatment group as replicate.Completely randomized design as used in this study.The thirteen groups ere subsequent of broiler chickens that ere fed diet containing commercial feed supplement as a control (P1),10 g/kg SAE and 1%LO (P2);10 g/kg SAE and 1%LO plus 60 mg vitamin E (P3),10 g/kg SAE and 2%LO (P4),10 g/kg SAE and 2%LO plus 60 mg vitamin E (P5),10 g/kg SAE and 3%LO (P6),10 g/kg SAE and 3%LO plus 60 mg vitamin E (P7),18 g/kg SAE and 1% LO (P8),18 g/kg SAE and 1%LO plus 60 mg vitamin E (P9),18 g/kg SAE and 2%LO (P10),ere 18 g/kg SAE and 2%LO plus 60 mg vitamin E (P11),18 g/kg SAE and 3%LO (P12),and 18 g/kg SAE and 3%LO plus 60 mg vitamin E (P13).The data ere analyzed by analysis of variance and if it ere significant,it ere then determined by Duncan's Multiple Range test.The present results showed that supplementation of SAE and LO significantly affected (P<0.05)fat deposition in abdomen and leg,but it had no effect on neck fat deposition and Fatty Liver Score.Supplementation of SAE and LO had significantly reduced (P<0.05)cholesterol content and thiobarbituric acid (TBA)in leg meat,but it significantly increased (P<0.05)vitamin A and vitamin E and it had no effect on fat in leg meat. Supplementation of SAE and LO proved to change fatty acid composition in leg meat.The treatment highly significant increased ecosapentaenoic acid (EPA)and docosahexaenoic acid DHA (P<0.01), arachidonic acid and stearic acid (P<0.05),but it significantly reduced linolenic acid (P<0.05).In conclusion,the supplementation of SAE and LO reduced fat deposition in abdomen and leg,the content of cholesterol in meat,and it enriched EPA and DHA of meat.
