Abstract

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.

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

The solid state fermentation technique on palm kernel meal by using Aspergillus niger wild type and NRRL 337 was studied. The fermentation was carried out at 30oC for 3 days continued with enzymatic process at room temperature and 40oC for 2 days. The result showed that at the third days of fermentation spores started to grow on the surface. The 3rd days fermentation can improve protein content and in vitro digestibility (IVDMD) with minimal loss of dry matter. The dry matter contents at 3 days fermentation were 48.88 and 48.83% for product using Aspergillus niger wild type and NRRL 337. Combination 3 days fermentation and 2 days enzymatic process at room temperature by using Aspergillus niger NRRL 337 type gave the best product with optimal IVDMD value and protein digestibility of 51.47 and 71.33%.   Key words : Palm kernel meal, fermentation, Aspergillus niger

Abstract

feed. Two hundred and ten, day-old broiler chicks were used for this study. They were allotted to 6 different diets containing either BIS or FBIS at 3 different levels (5, 10 and 15%) and one control diet. The results showed that 5% BIS and 5% FBIS could be used in broiler diet without adversely affecting feed intake, weight gain and feed conversion ratio. FCR of those diets were significantly (P<0.05) better than the control diet. Carcass yields were not significantly affected by feeding of BIS nor FBIS. The FBIS diet produced less abdominal fat than the BIS diet.   Key words : Palm kernel cake, fermentation, broilers

Abstract

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.   Key words : Ducks, palm kernel meal, fermentation

Abstract

Solid substrate fermentation by Aspergillus niger has been carried out to improve the nutritive value of palm oil sludge (POS). POS was fermented aerobically for four days in a fermentor chambers (28°C, RH 80%), with 60% moisture content Some of the product was further incubated anaerobically for 2 days at 28°C. Both products from aerobic and anaerobic fermentation processes were dried by various methods, i.e. sunlight, oven at 60°C, oven with blower at 40°C, at the moisture content less than 11%. Results of the drying methods were also compared with the fresh fermented product. Statistic analysis using factorial design (2 x 4) showed that there was no interaction between kind of fermentation processes (aerobic and anaerobic) and drying methods (fresh, sunlight, oven 60°C, and blower 40°C) for almost all parameters except total a-amino acid content Significant results (p<0.05) were obtained on the drying methods for parameters of crude protein, true protein, in vitro dry matter and protein digestibilities, and mannanase and cellulase activities. There were no significant results between treatments in the crude fiber analysis and soluble nitrogen content Significant results also did not occur between treatment of aerob and anaerob fermentation processes for almost all parameters except for dry matter digestibilities. Results from true protein and in vitro digestibilities show that the fresh fermented product has the best nutritive value, while product dried by sunlight was best among other drying processes. Results from in vivo of protein and energy digestibilities show that there were better metabolizable energy and protein for product with aerobic process and dried with oven and blower treatments, while sunlight drying was best for product processed in anaerobic condition. Although fresh fermented product gave better result from in vitro digestibilities and enzyme activity analyses, for some reasons (easy handling and preservation) sunlight drying gave best results for products processed under anaerobic condition, especially when sunlight drying is cheap.   Key words: Palm oil sludge, fermentation product, Aspergillus niger, thermal drying

Abstract

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 (28°C and 32°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 28°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 32°C for 3 days and continued by enzimatic process.   Key words: Fennentation, nutritive value, palm oil sludge

Abstract

Palm oil sludge a by product of palm oil industry is not commonly used in poultry feed due to some limiting factors such as low protein and amino acids content and high fiber content. These limiting factors were expected to be reduced by fermentation technology. Therefore an experiment was conducted to study the use of fermented (FLS) and non-fermented palm oil sludge (LS) for broiler chicken feed. Two hundred and ten day-old broiler chicks were used for this study. The birds were allocated into 35 cages with 6 birds in each cage. Each 5 group of birds were fed with one of 7 experimental diets. All diets were formulated with similar nutrient contents containing either LS or FLS at 3 different levels (5, 10 and 15%) and a control diet with no LS or FLS. The experimental diets were fed for 6 weeks and the performances were observed. Carcass yield, abdominal fat, weight of liver and gizzard were also measured at the end of the trial. The results showed that LS or FLS can be included in broiler’s diet, since the mortality, carcass yield, abdominal fat, liver and gizzard were not significantly affected. Best level inclusion of LS was 5%. Although inclusion of 10-15% LS did not affect growth and feed conversion significantly, the feed intake was significantly depressed. The best level inclusion of FLS was 10%, since higher level (15%) caused growth depression.   Key words: Palm oil sludge, fermentation, broilers
