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.

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.

Inclusion limit of palm oil sludge (POS) in poultry diet varies according to processing, and species or strain of the animal. Therefore, an experiment was conducted to study the utilization of fermented (FPOS) and non-fermented palm oil sludge (POS) for growing drakes. A number of 224 one week-old male ducklings were randomly distributed into 7 dietary treatments, with 4 replicates and 8 ducklings for each replicate. The dietary treatment consists of 2 kinds of feedstuffs (POS and FPOS) with 3 levels (5, 10, and 15%) and one control diet consisting neither POS nor FPOS. All diets were formulated with similar nutrient contents and meet the requirement of growing duckling and fed to 8 weeks old. The results showed that at the first week of the trial, feeding of POS or FPOS significantly (P<0.05) depressed growth of the ducklings, although the feed consumption was higher than the control. However, overall performances (body weight, feed consumption and feed conversion) of the ducklings, carcass yield, liver weight, gizzard weight and abdominal fat weight measured at the end of the trial were not significantly (P>0.05) affected by the dietary treatments. Therefore, it is concluded that it is safe to include POS or FPOS up to 15% in the diet of growing ducklings. Key words: Palm oil sludge, fermentation, ducks, growth

The performance of male duck fed different levels of crude palm oil I.A.K Bintang; Budi Tangendjaja

An experiment was conducted to evaluate the optimum level of inclusion of crude palm oil (CPO) in ducks diet . The treatments consisted of 5 different levels ofCPO (0, 5, 10, 15 and 20%) with 5 replicates and 10 day-old ducks/replicate. The ducklings were allocated in litter system covered with rice hull . At 0-3 weeks old, ducklings were fed with starter commercial diet . The experiment diet was given to starter (3 - 5 weeks old) and to grower (5-8 weeks old) ducks containing crude protein 19 .5 and 17%, respectively and metabolizable energy 2,900 kcal/kg. Measurements done were on body weight, feed consumption, carcass weight, internal organ and abdominal fats . There were no significant difference among treatments on body weight gain, feed consumption, feed conversion, carcass or internal organ weight . There was an increase on abdominal fat with an increase level ofCPO in the diet. Male duck had the ability to accept up 20% CPO in the diet without any negative effect. Key words: Performance, male duck, crude palm oil

Solid heavy phase (SHP), a by product material of palm oil factory obtained by ceramic filtration from liquid waste could be produced approximately 2 million tons/year. The by product has a potential for substituting corn in poultry feed. A series of experiment was carried out to improve nutrient value of the SHP in order to obtain a feedstuff that can substitute corn in poultry feed. The SHP was processed by either fermentation or enzymatic process. The product was then dried and analysed for its nutrient values. Fermentation process was carried out by altering the dry matter of the substrate (40 or 50%), while enzymatic process was carried out by altering the dose and kind of enzymes used. The process that produced best nutrient values was considered for producing materials for a feeding trial. In this trial, the products were used in diet formulation to substitute 25 or 50% of the corn included in the control diet. The results showed that the fermentation processed could be conducted with dry matter of substrate at either 40 or 50%. The fermentation process significantly improved the nutrient values of the SHP as shown by decreasing the crude fibre and increasing the crude protein, amino acids and the ME value. The results also showed that the Balitnak enzyme (BS4) was optimum when added at 10 ml/kg dry matter SHP, while the commercial enzyme (EK) was optimum at level of 2 g /kg dry matter SHP. Results of feeding trial showed that 25% of corn in layer diet could be substituted with dried SHP or SHP + enzymes. This substitution tended to improve performances (egg production, egg weight and FCR) of the laying hens. Substitution of 25 or 50% corn with the fermented SHP tends to reduce the performance of the layinghens. Similar trend also occurred when 50% of the corn was substituted with the enzymaticly processed SHP. Key Words: Solid Heavy Phase, Palm Oil Waste, Fermentation, Enzymes, Laying Hens

study were 14 days old local male duckling . The experimental rations were formulated to contain unfermented or fermented of sago waste at graded level of 5, 10, 15 and 20%. A ration without sago waste was also formulated and used as a control diet . All rations were formulated to be isoprotein and isoenergy, i .e . : 17% crude protein and 2,700 kcal ME/kg, respectively. Feed was pelleted and were given ad libitum. The experimental design used was completely randomized with 4 replicates, and each replicate consisted of 10 ducklings . The trial was conducted until 8 weeks old . The fermentation process could increase the nutrient content in sago waste . The unfermented sago waste could be included up to 5% in ration of duckling . At the higher, the final body weight and body weight gain were lowered as compared to the control ration . The fermentation process could be used up to 10%. The use of sago waste did not affect the feed consumption, percentage of carcass and liver weight significantly . Ration with 15% sago waste product a heavier giblets than the control ration . The use of fermented sago waste at 20% in the ration gave the FCR value higher as compared to control ration . It is necessary to study further the protein quality of fermented sago waste . Keywords: Sago waste, fermentation, male duck
