Abstract

An experiment had been carried out to study the effect of supplementation of humic acid via drinking water as natural feed additive on the performance of broiler chickens, in order to find the replacement of antibiotic, which recently known had negative effect on the consumen. Three hundred and twenty of day old broilers were divided into 4 treatment groups: (I) control (without humic acid); (II), (III) and (IV) with 100, 200 and 300 mg l-1 humic acid in the drinking water, respectively. Each group consisted of 4 replications with 20 birds each replication. The drinking water contained 2 mg l-1 probiotic. The birds were kept in litter system; feed and water were given ad libitum for 5 weeks. The parameter measured were body weight gain, feed convertion ratio (FCR) and percentage of carcass. The treatments had a significant effect on both body weight gain (P<0.05) and FCR (P<0.05). Body weight gain of control (I) 1839 g head-1 5 weeks-1, with FCR 1.66 were poorer than that of the group received humic acid: 1882 g head-1 5 weeks-1, 1.66; 1881 g head-1 5 weeks-1, 1.64; and 1874 g head-1 5 weeks-1, 1.59 for treatments II, III and IV, respectively. There were no significant different (P>0.05) between treatment II, III and IV neither on body weight gain nor FCR values.The treatments had no significant effect on carcass yield, 66.28 ± 1.78; 67.06 ± 3.11; 67.63 ± 2.06 and 67.68 ± 2.21% for treatments I, II, III and IV, respectively. It is concluded that humic acid has a potential effect as natural feed additive, which could improve growth and feed efficiency without affecting carcass yield.

Abstract

Palm kernel cake has a relatively high protein content, however its degradability in the rumen is high resulting in loosing its function as protein source for ruminant. This experiment was aimed toinvestigate the effect of feeding molasses protected palm kernel cake (BIS-M) on growth of young male Ettawah Grade (Peranakan Etawah = PE) goat. Twenty four (24) PE goats were divided into 4 groups and allocated to respective feeding BIS-M treatments. The treatments were R0 = control (without BIS-M), R1 = 15% BIS-M, R2 = 30% BIS-M and R3 = 45% BIS-M. The concentrate was fed at 400 gh-1d-1 for each individual in all treatment groups, while napier grass (Pennisetum purpureum) was offered ad libitum. The live weight of the goats were between 17-18 kg at the beginning of experiment. Feeding trial was carried out for 14 weeks consisting of 2 weeks for preliminary and 12 weeks for growth performance period. The digestibility study of the nutrient was carried out during the last 7 days of  the experiment. The experiment was arranged in a completely randomized design with 6 replications. Drinking water was available at any time. Feed intake was recorded daily while the body weight was recorded every 2 weeks. The parameters of observation were feed intake, live weight gain, nutrient digestibility and feed conversion ratio. The results indicated that the dietary treatments affected the intake and digestibility of nutrients, average daily gain and feed conversion ratio (P < 0.05). The total feed dry matter intakes were 599,30; 620,74; 690,19 and 740,04 gh-1d-1 with DM and Protein digestibility of 64.74 and 75.99; 67.47 and 73.05; 70.06 and 73.02; and 72.88 and 72.25% respectively for R0, R1, R2 and R3. The ADG were 42.06; 52.78; 61.90 and 70.24 g; with feed conversion ratio of 14.68; 10.51; 9.08; and 9.85 for R0, R1, R2 and R3. It was concluded that BIS-M can be used as source of protein with optimal utilization level at 30% of the concentrate. Key Words: Palm Kernel Cake, Molasses, Ettawah Grade goats, Performance

Abstract

Cassava waste is a by-product of cassava flour industry and its amount is increasing following the increasing of cassava flour industry. Its utilization as a feedstuff, is limited by its low protein content. The cassava waste is only utilized as the energy source. One of the alternative technology in improving the utilization of cassava waste as a feedstuff, by improving the nutritive value through fermentation process. Fermentation was carried out by solid substrate fermentation using Aspergillus niger as an inoculant and mixing with urea and ammonium sulphate as inorganic nitrogen sources. The nutritive value of the product was evaluated by feeding trial using 144 “Shaver Stabro” strain 3 days old chicks with 3 treatments i.e. 0 (control), 5.0 and 10.0% fermented cassava waste. The results showed that the true protein content of fermented cassava increased from 2.2 to 18.4%. The inclusion of fermented cassava waste up to 10% in chicken broiler ration for 4 weeks feeding did not affect the feed consumption, bodyweight gain, FCR, weight of liver and gibblets. All parameter results from 10% inclusion were not significantly different (P>0.05) with the control (0% inclusion).   Key words: Fermentation, cassava waste, utilization, broiler chickens

Abstract

It is noted that the delay of any information will attract some negative reaction because it would be useless. The objective of this study is to analyze the influence  of profitability, profit and loss, auditor opinion, public accountant size, auditor previous opinion, going concern and company size towards the audit delay in banking companies that have been listed in Jakarta Stock Exchange, Indonesia in 2005 until 2009. This research used census method on the companies that have been listed in Jakarta Stock Exchange. The analysis of hypothesis is using Multiple Regressions. Prior to hypothesis test, normality of the data test was done using kolmogorof-Smirnov test. The result of multiple regression model shows that audit delay was influenced by profitability and auditor previous opinion, with the  significance at 10%. Yet, profit and loss, public accountant size, auditor opinion, company size and going concern were not significant factors. Based on such results, it is recommended that the auditor should increase the effectiveness and efficiency of his audit performance and, for all existing studies; they should contribute to the current  literature on Auditing.

Abstract

A trial was conducted to determine the effect of various level of cassapro (fermented cassava) and halquinol supplementation on the performance of broiler chickens . Experimental rations were formulated isoprotein and isoenergy with graded level of cassapro (0, 10, 20 and 30%) . The 20 and 30% cassapro ration were prepared without and with halquinol supplementation (60 ppm). Each ration was fed to 40 of three day old broilers, divided into 4 cages ( 5 males and 5 females per cage) for 4 weeks. Increasing the level of cassapro significantly reduced body weight gain (P < 0.005), increased feed conversion ratio (FCR) (P < 0.0005) with no effect on feed intake (P < 0.10) . Halquinol supplementation has no effect on feed intake, but significantly increased body weight gain (P <0.05) and improved the FCR (P < 0.01) . It is concluded that high level of cassapro in the ration will cause poorer performance of the birds, however it can be alleviated by halquinolsupplementation.   Keywords: Broiler, cassapro, halquinol

Abstract

A series of chemical, biological assay and growth trials were conducted to determine the nutritive value of hominy, relative to corn. The crude protein, ash, NDF and ADF content of hominy were 10.25%, 2.10%, 19.10% and 4.70% respectively, and are higher than the corn level, 8.5%, 0.40%, 2.30% and 1.90% respectively. While its crude fat (3.20%) and metabolize energy (3,020 kcal/kg) contents were lower than the corn level 4,40% and 330 kcal/kg. Seven hundred DOC broilers of commercial strain were used for growth trial for 42 days. The birds were divided into 5 treatments group with 4 replications (35 bird/replicate). Experimental rations, starter and finisher, were formulated with graded levels of hominy on the expense of corn (A = 0%, B = 33.3%, C = 50%, D= 66.6% and E = 100%) with similar level of crude protein and metabolize energy. Feed consumption was not affected (P>0.05) by the treatments, however body weight gain (BWG) and feed conversion ratio (FCR) were both significantly (P<0.05) affected by the treatments. Body weight gain of treatment A (1,712 g) was similar to treatment B (1,683 g) and C (1,682 g) but significantly (P<0.05) higher than treatment D (1,598 g) and E (1,570 g). Feed convertion ratio of treatment A (2.17) was similar to the treatment B (2.26) but significantly better (P<0.05) than treatment C (2.30), D (2.36) and E (2.39). Carcass quality was not affected by the treatments except for the shank color, where treatment A (7.38) was significantly yellower than the other treatments (B=2.50, C=2.75, D=1.75 and E=1.0). It is concluded that the protein content of hominy is higher than corn, but its metabolize energy was lower than the corn. Hominy could be included in the ration replacing corn up to 33.3% without affecting performance of the bird.   Key words : Poultry, hominy, nutrient

Abstract

Enzyme (mannanase and cellulase) activities and fibre (hemicellulose, cellulose and lignin) contents were determined during the fermentation course of palm oil sludge with Aspergillus niger TL (wild type) and A. niger ES I (an asporogenous mutant). The analyses were carried out at the incubation time of 3 and 4 days of aerobic fennentation and at 2 days of anaerobic fermentation afterward. The correlations between mamlanase activity with hemicellulose content and cellulose activity with cellulose content were calculated by linear regression . The activities of matutanase and cellulase are increasing during the aerobic fennentation, while in the anaerobic fennentation the enzyme activities are decreasing due to instability of the enzymes. The enzyme activities of ESI are higher than the TL. The regression coefficient is highly significant for correlation between mamlanase and hemicellulose content of fermented product by ESI (r = 0.83; P<0.01) . While other correlations are not statistically significant (P>0 .05) . Marutanase and cellulase activities were also detected after the fermented product dried at 60°C which indicated the enzymes are quite stable .
