Indonesia is still importing corn for feed. Utilization of nonconventional feedstuffs may reduce this importation. One of them is solid heavy phase (SHP), i.e., a solid substance gained after filtration of liquid waste of crude palm oil factory with a potential production approximately 2 million ton/year. This research was carried out to study the utilization of SHP to replace corn in broilerâs diet. The SHP was dried and analysed for its nutrient compositions. The metabolisable energy was measured by using hens. Feeding trial was then conducted by replacing corn with SHP in various levels, i.e., 0 (Control), 10, 20, 30, and 40%. All diets were formulated to be isocalori dan isonitrogen. Five hundred broilers DOC were used in this trial and fed for 5 weeks. The performances of the birds were obsereved as parameters. Results showed that the ash, minerals crude fibre and fat contents of the SHP were higher than the corn. The crude protein of the Â SHP was similar to that of corn, but some amino acids content of the SHP were lower than the corn. The AME and TME values of SHP were 3271 and 3465 cal/g, respectively. Results of feeding trial showed that body weight of the birds were less as the level of SHP to replace corn increased in the diet. The FCR also showed impared as the levels of SHP increased in the diet. However, replacement of 10% corn with SHP did not significantly affect the body weight and FCR as compared with the control. Feed consumptions of the birds were not significantly affected by replacing corn with SHP. Carcass yield and relative weights of some internal organs were not significantly different between dietary treatments. It is concluded that the solid heavy phase could be used to replace 10% corn in broilerâs diet. Key Words: Solid Heavy Phase, Palm Oil By Products, Broilers

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

Utilization of jatropha seed meal as a feed ingredient is limited by the presence of several anti nutritive and toxic compounds in the seed meal. The aim of this research is to evaluate feeding of jatropha seed meal detoxified using fermentation by two fungi and rumen microbes (as biological detoxification) and using a combination of chemical and physical treatments on broiler performance. One hundred seventy five chicks (7 days old) were used and were divided into 5 treatments in 7 replications and each replication in one cage consisted of 5 chicks. R1 was control feed (K) without jatropha seed meal., 2) R2 was feed with 4% of Jatropha seed meal fermented by Neurosphora sitophila (FNS), R3 was feed with 4% of Jatropha seed meal fermented by Aspergillus oryzae (FAS), R4 was feed with 4% of Jatropha seed meal fermented by rumen microbes and R5 with 4% of Jatropha seed meal treated by autoclaved, refluxed by hexane and soaked in methanol (OEHM). Treated feed was given for 14 days at the end of the feeding treatment, two chickens from each replication were slaughtered and organ weights were recorded.Â Body weight of chicken and feed conversion ratio were calculated. The rest of the chicken was fed commercial feed for the next 7 days (recovery periode).Â Chicken mortality was almost 0% but 1 chicken from FAS treatment died at the recovery period. Feed consumption was lower at fermented jatropha seed meal than control (K) or OEHM, resulted in lower body weight of chicken. The abdomen fat weight and organ weights especially pancreas or spleen resulted from treatment with jatropha were much lower than that of K. In the recovery period, body weight of chicken in the OEHM treatment was almost similar from that of control chicken. In conclusion, biological detoxification on BBJ was able to reduce chicken mortality but could not improve the daily gain higher than control treatment. The best method to detoxify jatropha seed meal was the combination of physical and chemical treatment (using autoclave, followed by hexane and methanol extractions).

Feed additives are commonly added in poultry feed as a growth promotant or to improve feed efficiency. The most common feed additive used is antibiotic at sub-therapheutic doses, although there is a controversy on its impact on human health. Previous results showed that Aloe vera gel could improve feed efficiency in broilers and an in vitro study showed that the extract have an antibacterial effect. Therefore, a further experiment was designed to study the response of broilers to Aloe vera gel or its extract as feed additives. Aloe vera was prepared in dry gel or chloroform-extract and included in the diet at levels of 0.25; 0.50 and 1.00 g/kg (equal to dry gel). Standard diets with or without antibiotic were also formulated as control and a commercial diet was included for comparison. The diets were fed to broilers from day old to 5 weeks. Each treatment has 9 replicates and 6chicks/replicate. Parameters observed were: feed consumption, weight gain and feed convertion ratios. Carcass yield, abdominal fat levels, relative weight of liver, gizzard, tractus digestivus and length of tractus digestivus were also measured at the end of feeding trial. The results showed that Aloe gel and its extract did not influence body weight gain and feed consumption of broilers significantly (P>0.05), but improved feed convertion slightly (3.50%). The response in this trial was similar as thosecommercial diet and diet added with antibiotic. There was no significant (P>0.05) effect of Aloe vera bioactives on carcass yield, abdominal fat level and relative weight of liver. However, Aloe vera gel and its extract tend to increase gizzard weight, gastro intestinal weight and length. The Aloe vera gel and its extract also reduced the total count of aerobic bacteria in the digesta of tractus digestivus. It is concluded that the Aloe vera gel improve feed efficiency in broilers by increasing the size of tractus digestivus and reducing the total count of aerobic bacteria in the gastro intestinal tract.

An experimentwas conducted to study the utilization of local rock phosphate or natural defluorinated calcium phosphate (NDCP) as phosphorus source for layer chickens by using the imported dicalcium phosphate (DCP) as a reference. Eight experimental diets consisted of 2 source of phosphorus (DCP and NDCP) and 4 dietary total P levels (0.4, 0.5, 0.6 and 0.7%) were formulated. Each diet was fed to 24 pullets (6 replicates with 4 birds each) from 20 weeks of age to 14 weeks of egg production. Observations were made on feed consumption, egg production, egg weight, mortality, egg quality, Ca and P retention and ash content of tibial bones . Results showed no significant effect of different source and level of phosphorus tested on egg production (% HD), feed consumption, egg weight and mortality rates . Egg shell thickness was depressed in NDCP diet as compared with DCP, however this only occurred at firstmonth of production. It is concluded that the NDCP can be used in layers diet to replace DCP as phosphorus source. The relative biological value of phosphorus inNDCP is 96% for layers.

A series of experiment was carried out to evaluate the use of palm kernel meal and its fermented product in the ration of growing ducks. Treatments were arranged in a 2x3 factorial experiment, i.e. the combination between two processes (unfermented and fermented palm kernel meal) and three levels of ingredients in the diet (5, 10 and 15%). Four replicates were applied for each treatment, with 8 ducklings in each replicate. A control diet with no palm kernel meal was also formulated. All diets were formulated to have a similar protein and ME contents. Results of the experiment showed that fermentation process increased the nutrient composition (crude protein, true protein, phosphorus, and the metabolizable energy) and reduced its fibre and fat content. The feeding trial showed that neither the fermentation process, levels of ingredients nor the interactions of the two factors affected final body weight, feed consumption, feed conversion, carcass percentage and abdominal fat of the ducklings significantly. It is concluded that fermentation process improved the nutritional value of palm kernel meal and the inclusion of palm kernel meal (unfermented and fermented), up to 15% in the diet of ducks did not negatively affect the growthperformance and the carcass yield.

An experiment was conducted to study the effect of fermented palm oil sludge (PaS) incubated with different ways towards metabolic digestibility on dry matter,true metabolizable energy (TME) and protein digestibilities. A completely randomized design was used. Treatments consisted of unfermented pas (control) and fermented pas with and without enzymatic incubation proces, two levels of incubation temperatures (28Â°C and 32Â°C) and three levels of incubation times (3, 4 and 5 days). The digestibility studies were carried out in 46 layer. The results showed that the dry matter digestibility of P_S was not significantly affected by fermentation process neither by incubation times. TME was not affected by fermentation process and incubation times, but it was significantly affected by incubation temperatures during fennentation (P<0,05). Incubation temperatures at 3rC more significant than 28Â°C. Enzimatic process was more significant than without enzimatic process. True metabolizable energy was highly significantly affected by enzimatic process (P<O,OI). Protein digestibility was highly significantly affected by time and incubation process (P<O,Ol), but not significantly affected by temperatures incubation. It was concluded that fermentation process could improve the digestibility of palm oil sludge (paS). The best result obtained from incubation at 32Â°C for 3 days and continued by enzimatic process.

There was no significant (P>0.05) effect of Aloe vera bioactives on carcass yield, abdominal fat level and relative weight of liver. However, Aloe vera gel and its extract tend to increase gizzard weight, gastro intestinal weight and length. The Aloe vera gel and its extract also reduced the total count of aerobic bacteria in the digesta of tractus digestivus. It is concluded that the Aloe vera gel improve feed efficiency in broilers by increasing the size of tractus digestivus and reducing the total count of aerobic bacteria in the gastro intestinal tract.

Fermentation processes increase the protein of palm oil sludge and produce some useful enzymes. However, drying process, especially with heating often affects the nutritive values of feed ingredients and the enzymes activity. Therefore, this experiment was designed to study the responses of native chickens when fed ration containing fresh or dried fermented palm oil sludge (FPOS). Experimental diets with different levels of fresh or dried FPOS (5, 10 and 15% equal to dried FPOS) were formulated with similar nutrient contents. A control diet with no FPOS was also included. Each treatment was replicated 5 times for 12 weeks. Performances (body weight, feed consumption, feed conversion and mortality) of chickens were recorded. Carcass yield, abdominal fat content, weight of liver and gizzard were measured at the end of feeding trial. Data were subjected to analysis of variance and different between means were tested by orthogonal procedures. Results during the starting period showed that, chickens fed FPOS diet gain more weight significantly than the control birds (298.1 vs. 264.7). The dry matter intake of the dry FPOS diet was significantly better than the fresh FPOS diet (2.88 vs. 3.32). The FPOS dietary levels did not affect body weight gain and dry matter intake of native chickens, significantly. However, increasing the FPOS levels worsen the dry matter conversion (DCR) significantly. Data during 12 weeks trial showed mat the body weight gain was not significantly affected by treatments. The dry matter intake of the FPOS diets were significantly higher than the control diet (3469 vs. 3065 g/bird), hence the DCR of the control diet was significantly better than the FPOS diets (3.28 vs. 3.62). Feeding dry FPOS resulted in a better DCR as compared to fresh FPOS (3.48 vs. 3.76), but not affected the dry matter intake. The FPOS dietary levels did not affect body weight gain and dry matter intake of native chickens, significantly. However, inclusion of 5% FPOS in me diet gave better DCR significantly, as compared with 15% FPOS (3.51 vs. 3.83). Feeding dry or fresh FPOS (5 - 15%) did not significantly affect the mortality, carcass yield, abdominal fat levels, weight of liver and weight of gizzard of native chickens. It is concluded that dry FPOS was better than the fresh FPOS and could be included in me native chickens diet up to 10%. Key words: Palm oil sludge, fermentation, native chickens
