Abstract

The present study was conducted to evaluate effect of age on hepatic lipogenic enzyme activities and lipid fraction in broiler chicks. Eighty broiler chicks were distributed into one group. Broilers were fed commercial diet and provided drinking water ad libitum. At 5, 10, 12, 15, 17,20,22,25,27, and 56 days of age (27, 42, and 56 days of age for serum and carcass collection), 5 chicks were selected based on weights and killed. Experimental results show that the older chicks would have lower specific activity of hepatic acetyl-CoA carboxylase (ACC) and fatty acid synthetase (F AS) activities (P<0,01). Age influenced hepatic triglyceride (P<0.05), serum cholesterol ester and free cholesterol (P<O.OI). The older chicks had higher serum phospholipid and triglyceride (P<0.01). The older chicks had higher carcass fat and abdominal fat (P<0,01), and lower carcass moisture (P<0.05). In conclusion, the older chicks had lower specific activities of hepatic ACC and FAS (lipogenic enzymes) with higher lipid accumulation.   Key words: Age, acetyl-CoA carboxylase, fatty acid synthetase, lipid accumulation, broiler chicks

Abstract

The present experiment was conducted to evaluate the effects of house type and early feed restriction on performance and fat deposition of unsexed broilers. Four hundreds seven-day old unsexed broilers (Arbor Acres CP 707) were distributed into eight treatment groups. Each treatment group was represented by five replicates of ten broilers each. Two types of house (cage vs litter) and four levels of feeding (ad lib., 75% ad lib., 50% ad lib. and 25% ad lib.) were tested as treatment factors. Broilers were feed-restricted for 6 days from 7 to 13 days of age and thereafter they were fed ad lib. Feed intake of restricted broilers during restriction period was calculated from feed consumed by ad lib. group in the previous day. Results showed that unsexed broilers raised in litter had higher body weight (P<0.05), lower abdominal fat and higher triglyceride concentration at 42 days of age (P<0.05), and lower liver fat and higher carcass percentage at 56 days of age (P<0.05). Early feed restriction reduced body weight of 42-day old unsexed broilers except for broilers fed 75% ad lib. At 56 days of age, restricted broilers had similar body weight to those fed ad lib. At 56 days of age, broilers fed 25% ad lib. had lower FCR (P<0.05), lower abdominal fat (P<0.05) and lower triglyceride concentration (P<0,05). In conclusion, unsexed broilers fed 25% ad lib. showed compensatory growth with better FCR and lower fat accumulation at 56 days of age. Broilers raised in litter had higher body weight and lower abdominal and liver fat deposition.   Key words: House type, early feed restriction, fat deposition, unsexed broilers

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

A study was conducted to determine the effects of Sauropus androgynus leaf extract on growth, carcass quality and the number of fecal microorganisms in broiler chickens. Forty-eight male Arbor Acres broiler chickens (21-d-old) obtained from a commercial hatchery were used in the present study. Experiment consisted of four treatment groups with four pen replicates of three broilers allotted randomly to each dietary treatment from day 21-42 old. One group was the control with no additional Sauropus androgynus leaf extract (SAE) (P0), and other three groups were given drinking water supplemented with 1.5 g (PI), 3.0 g (P2) or 4.5 g SAE/l water (P3). The diet used was a commercial mix (Crude protein: 19% and Metabolizable Energy 3200 kcal/kg). Feed intake significantly reduced in P2 or P3 as compared with the control (P<0.05). A decrease in feed conversion ratio was observed in treatment groups as compared with Po (P<0.05). Abdominal fat, neck fat and liver fat content were significantly reduced by SAE (P<0.05), while carcass fat content was not significantly different. Number of fecal Escherichia coli in P1 or P3 (P<0,01) and fecal Streptococcus sp and Salmonella sp. were significantly (P<0,01) reduced by SAE supplementation as compared with the control, while fecal Bacillus subtilis in P2 and Lactobacillus sp. in P1 (P<0,01) were significantly higher as compared with other groups. SAE (P2 or P3) also significantly improved meat taste, shank color but lowered meat color (P<0.05) as compared with the control group. It was found that the number of fecal Streptococcus sp was suitable to predict abdominal fat. In conclusion, the inclusion of SAE at 4.5 g/l drinking water resulted in the best performance and carcass quality.   Key words: Sauropus androgynus leaf extract, fat accumulation, broilers

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.

Abstract

The present experiment was conducted to evaluate the effects of house type and early feed restriction on performance and fat deposition of unsexed broilers. Four hundreds seven-day old unsexed broilers (Arbor Acres CP 707) were distributed into eight treatment groups. Each treatment group was represented by five replicates of ten broilers each. Two types of house (cage vs litter) and four levels of feeding (ad lib., 75% ad lib., 50% ad lib. and 25% ad lib.) were tested as treatment factors. Broilers were feed-restricted for 6 days from 7 to 13 days of age and thereafter they were fed ad lib. Feed intake of restricted broilers during restriction period was calculated from feed consumed by ad lib. group in the previous day. Results showed that unsexed broilers raised in litter had higher body weight (P<0.05), lower abdominal fat and higher triglyceride concentration at 42 days of age (P<0.05), and lower liver fat and higher carcass percentage at 56 days of age (P<0.05). Early feed restriction reduced body weight of 42-day old unsexed broilers except for broilers fed 75% ad lib. At 56 days of age, restricted broilers had similar body weight to those fed ad lib. At 56 days of age, broilers fed 25% ad lib. had lower FCR (P<0.05), lower abdominal fat (P<0.05) and lower triglyceride concentration (P<0,05). In conclusion, unsexed broilers fed 25% ad lib. showed compensatory growth with better FCR and lower fat accumulation at 56 days of age. Broilers raised in litter had higher body weight and lower abdominal and liver fat deposition.   Key words: House type, early feed restriction, fat deposition, unsexed broilers
