Abstract

The present experiment was conducted to evaluate effect of feeding methods of katuk extract on performance and carcass quality of broilers. Sixty 20-d-old male broilers were distributed to 5 treatment groups of 4 replicates with 3 birds each. One treatment group was fed basal diet without katuk extract (P0), whereas other treatment groups were fed basal diet plus 18 g katuk extract/kg diet (P1), basal diet plus 9 g katuk extract/l drinking water (P2), basal diet plus 9 g katuk extract/kg diet plus 4.5 g katuk extract/l drinking water (P3), and basal diet plus 4.5 g katuk extract/kg diet plus 2.25 g katuk extract/l drinking water (P4). Experimental results showed that weight gain of P1 and P4 were significantly higher (P<0.05) than those of P0 and P2. Feed conversion ratio of P1 and P4 were significantly lower than those of P0 and P2 (P<0.05). Feed intake, water intake, the weights of heart, liver and gizzard were not significantly different (P>0.05), but the weight of intestine was significantly affected (P<0.05) Abdominal fat of P4 was significantly lower than that of P0, P1 and P2 (P<0.05). Carcass color of P4 was significantly better than that of P0, P1, P2 and P3 (P<0.01). Katuk extract feeding had no effect on smell and taste of meat (P>0.05). P4 had better meat color than P0, P1, dan P2 (P<0.05). Katuk extract feeding had no effect on meat bone ratio, carcaas weight and cooking loss (P>0.05). In conclusion, in order to improve performance and carcass quality, broiler chickens could be given katuk extract through diet plus drinking water at level of 4.5 g/kg diet plus 2.25 g/l drinking water.   Key words: Katuk extract, performance, carcass quality, abdominal fat

Abstract

The present study was conducted to evaluate effects of supplementation of alkaloid or non alkaloid from Sauropus androgynus leaves on productive performance and the contents of lipid fractions in layer chickens. Forty two layer chickens aged 30 weeks were distributed to seven treatment groups. Each treatment group contained six layer chickens maintained in an individual cage, respectively. The present experiment used completely randomized experimental design. The seven treatment groups were as follows: 1)  Control, layer chickens were fed diet without supplementation of alkaloid or non alkaloid extracted from Sauropus androgynus (P0);  2)  Layer chickens were fed diet contained 30 mg non alkaloid/kg diet (P1); 3)  Layer chickens were fed diet contained 60 mg non alkaloid/kg diet (P2); 4)  Layer chickens were fed diet contained 90 mg non alkaloid/kg diet (P3);  5)  Layer chickens were fed diet contained 30 mg  alkaloid/kg diet (P4);  6)  Layer chickens were fed diet contained 60 mg alkaloid/kg diet (P5); 7) Layer chickens were fed diet contained 90 mg alkaloid/kg diet (P6). Layer chickens were fed experimental diet with 2,750 kcal/kg Metabolizable Energy (ME) and 16.0% protein. Diet and drinking water were fed ad libitum. Experimental results showed that supplementation of alkaloid or non alkaloid from Sauropus androgynus leaves significantly affected productive performance in layer chickens. It appear that non alkaloid supplementation had no advantage in improving productive performance, whereas supplementation of 30 mg alkaloid/kg diet might have advantages in improving productive performance as indicated by better egg production and lower feed conversion ratio. Treatment had no effect on glucose and triglyceride concentration in serum, but it affected total cholesterol, HDL-cholesterol, LDL+VLDL-cholesterol and atherogenic index in serum. Cholesterol concentration in serum was significantly increased in P4 and P6, whereas HDL-cholesterol concentration was significantly increased in P1, P2, P3, P4 and P5 as compared with the control group. Atherogenic index was significantly lower in P1, P2, P3, P4 and P5 as compared with control group. Egg yolk content was significantly lower in P5 as compared with the control group. Fatty liver score was significantly lower in P1, P2, P4, P5 and P6 as compared with the control group. Abdominal fat was significantly lower in P1, P4 and P6 as compared with the control group. Staphylococcus sp. in eggshell was significantly reduced in layer chickens fed diet with 30 mg non alkaloid/kg diet or 90 mg alkaloid/kg diet, whereas Escherichia coli was not reduced by the treatments.  In conclusion, both alkaloid and non alkaloid from Sauropus androgynus leaves were effective to reduce the risk of atherosclerosis occurrence. In addition, alkaloid was more effective in lowering egg cholesterol than non alkaloid. Both alkaloid and non alkaloid at a given level of supplementation reduced Staphylococcus sp. in eggshell.
