A series of experiment was conducted to improve the utilization of coconut meal in poultry ration . A bioprocess (fermentation) approach was adopted. Coconut meal was fermented followed by an enzymatic process at room temperature or 50 OC.The nutritive value of the fermented products was determined chemically. Product with the highest nutritive value was then used for a feeding trial to study the interaction effect between dietary levels of fermented coconut meal and phosphorous level on the performances of laying ducks. Nine experimental diets were formulated, i.e ., the factorial of 3 levels of fermented coconut meal (0, 30 and 40%) and 3 levels of total phosphorous (0.6, 0.8 and 1 .0%) . The diet was fed to pullet ducks and the performances of the ducks were observed for 16 weeks of production period. The results showed that the nutritive value of coconut meal increased by fermentation and the highest yield was achieved when the enzymatic process was performed at 500C. There was no significant interaction effect between dietary fermented coconut meal levels and the phosphorous levels on all parameters observed, except on egg weight. Inclusion of fermented coconut meal in the ration up to 30% did not produce negative effects on the productivity oflaying ducks, however, higher levels (40%) ofinclusion reduced the egg size Â Keywords: Coconut meal, fermentation, ducks, egg production

An experiment has been conducted to determine the effect of type of packaging and time of storage on fermented palm oil sludge. The palm oil sludge was fermented with Aspergillus niger, dried, kept in differentpackaging materials (plastic bags, feed bag, and paper bag) and stored under room temperatures for 12 weeks. The experiment was assigned in a split plot design (3x7). The parameters measured were water content, crude protein, soluble nitrogen, true protein, in vitro dry matter (IVDMD) and true protein digestibilities (IVTPD), total in vitro digestible protein, and the activities of mannanase and cellulase. Results showed that fermented palm oil sludge stored for 12 weeks increased the water content, decreased the true protein and fiber contents, and also reduced the activity of mannanase and cellulase and in vitro dry matter digestibility but no changes on the crude protein content, protein digestibility, and total digestible protein. It was concluded that fermented palm oil sludge should be kept in feed bag under room temperature if to be stored for 12 weeks. Â Key words : Palm oil sludge, fermentation, nutritive value, storage

Feed additives are commonly used in poultry feed as growth promotors or to improve feed efficiency. Previous results showed that Aloe vera bioactives could improve feed efficiency in broilers. Therefore, a further study was designed in order to obtain optimum doses and application methods of bioactives for broiler chickens. Aloe vera was prepared in different forms (fresh gel, dry gel, fresh whole leaf or dry whole leaf). The aloe was supplemented into the feed with concentrations of 0.25; 0.5 and 1 g/kg (equal to dry gel). Standard diets with or without antibiotics were also included as control. The diets were fed to broilers from day old to 5 weeks and the performances were observed. Results showed that the aloe-bioactives did not significantly (P>0.05) affect final body weight of broilers as compared with the control. Supplementation of 0.25 g/kg fresh gel, 0.25 and 1.0 g/kg dry gel significantly improved feed convertion by 4.7; 4.8 and 8.2%, respectively as compared with the control. This improvement was a result of reduction in feed intake or dry matter intake without reducing the weight gain. However, supplementation of whole aloe leafs could not improve feed convertion in boilers. It is concluded that the bioactives of Aloe vera could be used as feed supplement to improve feed efficiency in broilers with no deleterious effect on weight gain, carcass yield, abdominal fat levels and internal organs. The effective concentrations of aloe gell as a feed supplement based on dry matter convertion were from 0.25 g/kg fresh gel, 0.25 and 1.0 g/kg dry gel.

There are plenty of Indonesian plants contain usefull bioactive components. One of them is Aloe vera. Previous experiment showed that Aloe vera bioactives reduced aerob bacteria in the intestinal and improved feed efficiency in broilers reared in cages. The results however, gave some variations, may be due to variation in rearing the chickens. Two experiments were carried out to study the effectivity of Aloe vera bioactives as feed additives for broilers reared on deep litter. In the first study, six experimental diets in mash form were formulated, i.e.: Control (K); K + antibiotic; K + 0.50 g/kg dry Aloe vera (LBK); K + 1.00 g/kg LBK; K + anthraquinone; K + Aloe vera in semi-liquid form. The amount of semi liquid Aloe vera and the anthraquinone were equally to 1.00 g LBK/kg. Results showed that antibiotic improved body weight gain 6.10% and feed efficiency 5.50% better than the control, although statistically not significant (P>0.05). Aloe vera bioactives in low doses (0.50 g/kg) also improved weight gain (6.30%) and feed efficiency (5.20%) similar to the antibiotic. However, Aloe vera in high doses and anthraquinone (equal to 1.00 g/kg diet) did not improve performance of broilers. There were no significant changes on carcass yield, abdominal fat levels, weight of liver, gizard and gastro intestinal tract due to any feed additives tested. The second experiment were carried out to study the effectivity of feed additives when included in crumble diets. Six experimental diets, i.e.: Control (K), K + antibiotic, K + Semi-liquid Aloe vera (equal to 1.00g dry Aloe vera/kg), K + 0.50 g dry Aloe vera/kg, K + 1.00 g dry Aloe vera/kg, K + 0.50 g dry Aloe vera + 0.50 g Curcuma xanthorrhiza meal/kg. All diets were fed in crumble form. Results showed that chickens fed with feed additives (antibiotic or Aloe vera bioactives) have a significantly (P<0.05) higher body weight gain and feed efficiency than those fed with control diet. The best weight gain was achieved by low dose dry Aloe vera (1342 g/bird) and the lowest was the control (1039 g/bird). The best feed conversion ratio was achieved by antibiotic treatment (1.756) followed by low dose dry Aloe vera + curcuma meal (1.758) and the worst was showed by the control (1.908). It is concluded that Aloe vera bioactives at low dose (0.50 g/kg diet) could improve body weight gain and feed efficiency of broilers reared on deep litter. The improvement achieved was similar as the antibiotic. The bioactive is more effective when fed in crumble diets. Â Key words: Broilers, bioactives, Aloe vera

Semi liquid Aloe gel (LBSC) was preserved using sodium chloride (1, 2 and 3%) and sugar (10, 20 and 30%) for 7 weeks at 4ÂºC. Physical observations (color, odor and gas) and chemical analysis (total phenolic and emodin) were performed every week during preservation. Changing color was observed at the fourth week and until the seventh week. The total phenolic content decreased by 23.2, 12.9 and 19.0% in LBSC with 1, 2 and 3% salt respectively. The total phenolic content in LBSC with 10, 20 and 30% sugar decreased by 64.0, 53.8 and 30.4% respectively. The emodin content decreased by 60.7% for control (LBSC alone), but in LBSC with 1, 2 and 3% salt it was decreased by 26.2, 19.2 and 50.8% respectively. The emodin content in LBSC with 10, 20 and 30% sugar decreased by 70.5, 67.4 dan 82.4% respectively. Emodin was more unstable than total phenolic. Preservation using sugar was not preserve the availability of emodin, while salt could inhibit the decrease of emodin concentration in LBSC. Preservation of LBSC with 2% table salt gave the lowest decrease of emodin and total phenolic contentsKey words: Aloe vera, fenol, emodin, preservation
