Abstract

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

Abstract

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.  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).  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).

Abstract

The genetic distance among populations of Indonesia native sheep (Ciamis, Garut, Sumatera and Garahan), St. Croix and Merino were estimated to investigate the genetic relationship among those breeds. Blood protein polymorphism of transferin (Tf), post-transferin (PTf), albumin (Alb), post-albumin (PAlb) were detected from blood plasma, while haemoglobine (Hb) was detected from erythrocyte using Polyacrylamide Gel Electrophoresis (PAGE). Results of PAGE showed that Tf was controlled by 6 alleles, while Alb by 4 alleles, PTf by 3 Alleles and PAlb and Hb by 2 alleles. Value of breeding coefficient within individual subpopulations (FIS) for Tf (-0,0014), Alb (-0,0046) and Hb (0,0256) were not significantly different by noel. These results show that data of gene frequency are still following Hardy-Weinberg Equilibrium and inbreeding inside the sub population did not occur. The closest distance among the native breeds is the subpopulations of Ciamis and Garut due to neighboring area and similar traits of Thin Tail Sheep. The genetic distance of both population to Sumatera Thin Tail Sheep and Garahan Fat Tail are quite far. In addition to that results all Indonesian native breed were distinctly different from St. Croix and Merino.   Key words: Indonesian native sheep, St. Croix, Merino, blood protein polymorphism, genetic distance
