A study was conducted to evaluate the effect of enzyme supplementation on the performances of broiler chickens. One hundred and twenty five day old chicks (DOC) were allocated into five dietary treatment with 5 replicates. Every replicate had 5 DOC. The treatments were: control, control + 0.02% ß-xylanase, control + ß glucanase at three levels (0.05; 0.10 and 0.20%). The treatments were carried out in a randomized block design. Parameter measured were: feed intake, live weight gain and feed conversion ratio (FCR) at 3 and 5 weeks old, while carcass, internal organ, abdominal fat, thickness of intestine, and mortality were observed only at 5 weeks old. The results showed that enzyme supplementation did not significantly (P>0.05) affect feed intake and live weight gain of chicks at 3 weeks old, but the FCR of enzyme supplementation was significantly (P<0.05) better as compared with the control. FCR of birds fed with ß-glucanase tended to be better than the ß-xylanase supplementation (P>0.05). The enzyme addition did not significantly (P>0.05) affect all parameters recorded at 5 weeks old chickens. It is concluded that the best treatment for chicks at 3 weeks old was 0.05% ß-glucanace supplementation. This treatment improved 7.55% FCR as compared to the control.

Palm oil sludge a by product of palm oil industry is not commonly used in poultry feed due to some limiting factors such as low protein and amino acids content and high fiber content. These limiting factors were expected to be reduced by fermentation technology. Therefore an experiment was conducted to study the use of fermented (FLS) and non-fermented palm oil sludge (LS) for broiler chicken feed. Two hundred and ten day-old broiler chicks were used for this study. The birds were allocated into 35 cages with 6 birds in each cage. Each 5 group of birds were fed with one of 7 experimental diets. All diets were formulated with similar nutrient contents containing either LS or FLS at 3 different levels (5, 10 and 15%) and a control diet with no LS or FLS. The experimental diets were fed for 6 weeks and the performances were observed. Carcass yield, abdominal fat, weight of liver and gizzard were also measured at the end of the trial. The results showed that LS or FLS can be included in broiler’s diet, since the mortality, carcass yield, abdominal fat, liver and gizzard were not significantly affected. Best level inclusion of LS was 5%. Although inclusion of 10-15% LS did not affect growth and feed conversion significantly, the feed intake was significantly depressed. The best level inclusion of FLS was 10%, since higher level (15%) caused growth depression. Key words: Palm oil sludge, fermentation, broilers

Feed efficiency of layer ducks is low since feed consumption is considerably higher than egg production. The experiment has been conducted to evaluate performances and age at first laying of MA crossbred duck from 1-20 weeks old on restricted feeding. Three experimental diets tested were: (1) 70% ad libitum = 70% A, (2) 85% ad libitum = 85% A and (3) 100% ad libitum = 100% A. Feed consumption, live weight gain (PBB), feed conversion ratio (FCR), mortality rate and age at first laying were recorded. Live weight gain of ducks on 70 and 85%A were significantly (P<0.05) lower than 100% A for both at 12 weeks old. Live weight gain of duck at 16 weeks old fed 85% A was similar to the ducks fed 100% A. On the other hand, FCR of duck at 16 weeks old on 70 and 85% A were significantly (P<0.05) better than ducks fed 100% A diet. Age at first laying was delayed 9 days on duck fed 85% A and 21 days on duck fed 70% A diet. However, average weight of first laid egg was not affected by the treatments. Mortality increased on duck fed 70% A. This study indicated that feeding MA duck at rate of 85% of ad libitum was sufficient to support normal growth and reproductive development.

Fishy odor is one of off odor attributes local duck meat. Off odor reduces consumer preference on duck meat. This experiment was conducted to evaluate effect of fish meal levels and antioxidant in diets on the off odor intensity and fatty acid composition of local duck meat. The experiment was designed based on 2x3factorial experiment. The first factor was two fish meal level: low (TIR) and high (TIT), and second factor was three antioxidant level: none, 150 ppm santoquin (Sq) + 400 IU vitamin E (VE), and 400 IU vitamin E (VE) + 250 mg vitamin C (VC)/kg diet. One hundred and twenty MA (Mojosari♂ x Alabio♀) day old male duck were allocated into six treatments: (1) TIR, (2) TIR + 150 ppm Sq + 400 IU VE, (3) TIR + 400 IU VE + 250 mg VC (4) TIT, (5) TIT + 150 ppm Sq + 400 IU VE, and (6) TIT + 400 IU VE + 250 mg VC. Off odor intensity on raw and boiled meat, and fatty acid composition in boiled duck meat were used as parameters. The result indicated that fish meal levels did not significantly (P>0.05) affect the off odor intensity in raw and boiled meat. However, antioxidants supplementation significantly (P<0.05) reduced off odor intensity in both raw and boiled meat. Antioxidants supplementation in diet prevented the unsaturated fatty acids from lipid oxidation in boiled meat. This experiment suggests that supplementation of 150 ppm santoquin + 400 IU vitamin E or 400 IU vitamin E + 250 mg vitamin C to the duck diets were effective in reducing off odor and hence increased the sensory quality of duck meat.

Productivity and feed efficiency of Mojosari Alabio (MA) cross-bred duck on the first phase of laying from 20-43 weeks old was better when fed ad lib. using pelleted diet. An experiment was conducted to evaluate effect of restricted feeding of pelleted diet on second phase of laying of MA cross-bred duck performances from 44-67 weeks old. The experiment was designed in a Completely Randomized Design. 156 MA cross-bred ducks were devided into three groups and fed three experimental diets: (1) 70% ad lib., (2) 85% ad lib. and (3) ad lib. All experimental diets were fed to ducks for 24 weeks and feed intake, egg production, egg weight, FCR, molting, egg yolk weight, albumen weight, egg shell weight and egg yolk colour score were measured as parameters. The results showed that the restricted feeding of 70 and 85% significantly (P<0.05) reduced egg production, egg weight and egg yolk percentage, egg yolk colour score and induced early molting, but did not adversely affect egg white and egg shell percentage. FCR of duck fed 70% (6.47) was significantly (P<0.05) the worst compared to the duck fed 85% (4.13) and ad lib. (3.55). The results indicate that MA cross-bred duck was more efficient being fed ad lib. Key words: Restricted feeding, MA crossbred duck, productivity and egg quality

Termites containing high protein and various enzymes including cellulase enzyme produced by microbes in its digestive system. An experiment was conducted to evaluate the use of termite (Glyptotermes montanus) as poultry feed. One hundred and seventy five, day-old broiler chicks were used for this experiment. The broiler chickens were allotted to seven different diets: (1) control diet containing rice bran without termite (KD), (2) KD + 0.75% dried termites (RK), (3) KD + 1.50% RK, (4) KD + 3.00% RK, (5) KD + 14% fresh termite (RB), (6) KD + 4.29% RB, (7) KD + 8.57% RB. Feed intake, weight gain, feed conversion ratio (FCR), mortality, carcass and visceral were recorded for five weeks experiment. The results showed that chickens fed the diet containing 1.50% RK grew significantly (P<0.05) bigger than other diets. Feed intake of chickens fed KD + 1.50% RK was also significantly (P<0.05) higher than chickens fed other diet but was not significantly (P>0.05) different from feed intake of chickens fed KD, KD + 3.00% RK and KD + 8.57% RB. FCR of chickens fed RK or RB were not significantly different (P>0.05) from FCR of KD diet. Carcass weight of broiler chickens fed KD + 1.50% RK significantly (P<0.05) higher than carcass weight of chickens fed KD diet or improved carcass percentage of about 4.4%. This experiment also showed that the inclusion of termites in the diet significantly (P<0.05) increased percentage of gizzard, heart and abdominal fat weight of chickens.
