Abstract

An experiment was conducted to study the use of Aloe vera bioactives as feed additives on the performances of laying hens. The Aloe vera bioactives was prepared as the dry gel (DG) and semi liquid gel (SLG). The Aloe vera was suplemented into the diets with concentration of equal to 0.5 and 1.0 g DG/kg diets. Diets contained commercial anthraquinone, a bioactive compound of Aloe vera with doses equal to 0.5 g DG and 1.0 dg/kg were also prepared. Diets were compared to control diets containing with and without antibiotic. Two hundred of fifty six laying hens strain Isa Brown aged 19 weeks were used for the experiment. Each treatment had 8 replicates with 4 hens in each replicate. The treatments were carried out for 30 weeks and parameters measured were egg production (% hen day/HD), egg weight, feed conversion ratio (FCR), feed consumption, egg quality, and mortality. Results showed that feed consumption was not significantly different (P>0.05), however DG 1.0 g/kg and anthraquinone 0.5 g/kg tended to decrease the feed consumption. Egg production was not significantly affected by antibiotic, DG, SLG, or anthraquinone (0.5 g/kg), but anthraquinone 1.0 g/kg had more egg production than control. Higher concentration of DG, SLG, and anthraquinone 1.0 g/kg gave better FCR than those of lower dosage (0.5 g/kg). Haugh unit was not affected by the treatment while yolk weight, egg shell and shell weight was significantly decreased by anthraquinone 0.5 g/kg (P<0.05). Mortality from all treatments was only 1.6%. It was concluded that treated by anthraquinone was better than that by Aloe vera, however, they were not significantly different. For the healthy reason, the use of Aloe vera is more saver than the use of anthraquinone.     Key Words: Bioactives, Productivity, Layer

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

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
