Abstract

An experiment was conducted to study the response of broilers on the diet containing fermented palm oil sludge with Aspergillus niger stored at different length of time. The research was carried out in Research Institute for Animal Production Ciawi, Bogor. The experiment was conducted based on completely randomized design using 245 day old broiler chicks with 5 replicates. They were allotted to 7 diets containing one control without palm oil sludge (R0), 5 and 10% of fresh-fermented palm oil sludge (LSF) (R1 and R2), 5 and 10% of LSF stored at room temperature for 2 months (R3 and R4) and stored for 3 months (R5 and R6). Diets were fed ad libitum for 5 weeks. Feed intake, weight gain, feed conversion ratio, and carcass yields were observed as parameters. Results showed that no parameters were significantly affected by the treatments. It is concluded that 10% of fermented palm oil sludge could be included in diet of broilers even after three months storage at room temperature.   Key words: Broiler, fermented palm oil sludge, storage period

Abstract

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.   Key words: Broilers, bioactives, Aloe vera

Abstract

Semi liquid Aloe gel (LBSC) was preserved using sodium chloride (1, 2 and 3%) and sugar (10, 20 and 30%) for 7 weeks at 4ºC. 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

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

A study on the use of aloe vera bioactives as feed additive in layer ration was conducted. One hundred and twenty pullets strain Isa Brown were allocated into 5 treatments with 6 replicates and 4 birds/replicate. The treatments were: control,control+antibiotic (50 ppm zinc bacitracin), and control+ aloe vera at three levels (0.25; 0.50 and 1.00 g/kg). The treatments were conducted in a completely randomized design. Parameter measured were first initial body weight, age at 1st lay, feed intake, egg weight, hen day (%HD) and feed conversion ratio. The results showed that antibiotic and aloe vera used as additive for 9 months production did not significantly (P<0.05) affect all parameter measured, except feed intake of hens fed diet containing 0.5 g/kg aloe vera was significantly (P<0.05) higher than control. The addition of aloe vera at 1.0 g/kg significantly (P<0.05) reduced the feed intake as compared with the control, aloe vera 0.25 and 0.50 g/kg. The used of aloe vera (1.00 g/kg) produced egg weight significantly (P<0.05) higher than the control, and feed conversion ratio was significantly (P<0.05) better than the control and aloe vera (0.25 g/kg). It is concluded that the best treatment was the diet with aloe vera level at 1.00 g/kg. This treatment improved feed efficiency 8.40%.     Key Words: Bioactive, Egg Production, Layer

Abstract

A field trial was conducted to study the effectiveness of dry gel Aloe vera (DG) as a feed additive for laying hens in commercial farms. The trial was consisted of two treatments, one was control, commonly used farmer ration containing antibiotic of zinc bacitracin at 0.5 g/kg and the second feed containing DG equal to 1.0 g/kg. Every treatment had two replicates with 504 Loghman laying hens. The hen day production (% HD), egg weight, feed consumption, feed conversion ratio (FCR), egg quality comprising yolk colour, albumin and yolk weights, egg shell eight and thikness, and mortality were observed for 24 weeks. The results showed that feed consumption, % HD, egg weight, FCR, yolk colour, albumin weight, yolk weight, egg shell weight, and egg shell thickness were not significantly different (P>0.05) between the control and DG treatment, except for the Haugh unit (HU). Thus, it can be concluded that Aloe vera bioactives has the same effectiveness as antibiotic as a feed additive at the level of commercial farms.

Abstract

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.

Abstract

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 broiler’s 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  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 broiler’s diet. Key Words: Solid Heavy Phase, Palm Oil By Products, Broilers

Abstract

Research of nutritional evaluation of fermented copra meal and its application in broiler has been conducted. In the first experiment the crude protein and fiber contents were determined in the fermented copra meal using A. niger BPT, NRRL 337 and ES1. Further, 384 of Indian River DOC were used for in vivo experiment. Completed Randomized Design was used with 8 treatments: Control without and with 10% addition of copra meal, 3 levels of fermented copra meal addition with Aspergillus niger BPT or A. niger NRRL 337 (10, 15, 20%). Every treatment was repeated 8 time with 6 birds each. Variables measured were body weight, consumption, feed conversion, mortalities and carcass analyses. Diets were formulated in isocalori and isoprotein. The research was conducted in 6 weeks. The results showed that fermentation process increased the copra meal protein content from 22.3 to 36.1; 35.6 and 38.6% respectively for fermentation with A. niger BPT, NRRL 337 and ES1, decreased the crude fiber from 19.5 to 13.0; 18.9 and 8.28%. Results during 3 weeks trial show that the treatment significantly affected on broiler performance (P<0.05). Fermented copra meal was better than non fermented copra meal. There was no significantly different (P>0.05) in broiler performance at 6 weeks trial evaluation. The best conversion was in diet with 10% fermented copra meal with A. niger BPT and NRRL 337. The feed conversion of diets with 10% of each fermented products were better than control or diet without copra meal. The feed conversion of 15% fermented copra meal addition was not significantly different to control. Utilization of fermented copra meal with A. niger BPT or NRRL 337 should not more than 15%.

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
