A study on the use of dried Morinda citrifolia waste as feed additive in broiler ration was conducted. One hundred day old chicks (doc) were allocated into 4 levels (control; 0.0; 1.2; 2.4 and 4.8 g/kg feed) of M. citrifolia waste with 5 replication. Each replication had 5 birds. The treatments were allocated in a completely randomized design. Variables measured were: feed intake, live weight, feed conversion ratio (FCR), percentages of carcass and internal organs ( liver. gizard, abdominal fat, and thickness of intestine). The results showed that M citrifolia waste supply did not significantly (P>0.05) affect all variables measured, but feed intake of those fed with high levels (4,8 g/kg) of M. citrifolia waste was significantly (P<0.05) lower than those fed with 1.2 g/kg. FCR was significantly (P<0.05 ) lower as compared to the control; 1.2 and 2.4 g/kg. It is concluded that the best treatment was the supplementation of M. citrifolia waste of 4.8 g/kg, this treatment improved feed efficiency by 5% as compared to the control.

A trial was conducted in order to study the effect of the supplementation of Avizyme 1500Â® (Danisco Animal Nutrition, Marlborough, UK) on the performance of laying hens for one year. A control diet based on corn â soybean meal was formulated to meet nutrient requirement of ISA Brown laying hens. Two treatments, the control diet (C) and C + 1000 g Avizyme/tonne diet were tested. Each diet was fed to 80 birds (20 replicates of 4 birds) from 20 to 72 weeks of age, and performances of birds (feed intake, egg production, egg size, egg mass, feed conversion ratio, and egg quality) were measured. All data were subject to analyses of variance following the t-test. Results showed that the addition of Avizyme 1500 to the feed reduced feed intake by 4% (P < 0.01), mortality by 75 % or from 15% to 3.75% (P < 0.01) and improved the feed conversion ratio by 3 % (P < 0.05).Â The high mortality of the control treatment (15%) is explained by an E.coli infection that was observed following the post-mortem examination of dead birds. The egg production (HD and HH), egg size and egg mass however were not significantly affected by the Avizyme supplementation. Egg quality (HU, yolk colour score, yolk weight and shell thickness) was not significantly affected by Avizyme supplementation. It can be concluded that the supplementation of 1000 g Avizyme /tonne of diet improved feed efficiency and this was mediated via a reduction in feed intake.

Use of the rice bran as poultry feed is restricted by its high fibre content as poultry is unable to hydrolyse the fibre into available energy. This experiment was aimed The aim of this experiment was to investigate the effect of crude enzymes supplementation on performances of broiler chickens fed diets containing 30% rice bran. The experiment was based on completely randomized design with nine experimental diets. Diets 1-5 contained 5% less than recommended protein and energy, based on determined metabolizable energy (ME) content in the rice bran at 2040 kcal/kg, without taking into account on the beneficial effect of the enzyme supplementation. These diets were: 1. A control diet (D2040, without enzymes); 2. D2040 + E. javanicum (BS4) + P. nalgiovense (S11); 3. D2040 + BS4 + A. niger; 4. D2040 + BS4 + commercial enzymes (CE); 5. D2040 +Â B. pumilus (PU4-2) + CE. Four other experimental diets contained the same protein and energy levels as in the diets 1-5, but had taken into account on the beneficial effect of the enzyme supplementation,. These diets were:Â 6. D2702 + BS4 + S11; 7. D2650 + BS4 + A. niger; 8. D2465 + BS4 + CE ;and 9. D2465 + PU4-2+ CE. Each experimental diet was repeated six times and each replication consists of 5 day-old broiler chickens. Results showed that FCR of the chickens fed D2040 + PU4-2 + CE Â diet (FCR = 1.38) and D2465 + PU4-2 + CE diet (FCR = 1.46) were significantly (P < 0.01) improved compared to the control dietÂ (FCR = 1.64). This experiment strongly shows that supplementation of PU4-2 + CE enzymes significantly (P < 0.01) improved feed efficiency of the broiler chickens by 11-16%.

Feed additives are commonly added in poultry feed as a growth promotant or to improve feed efficiency. The most common feed additive used is antibiotic at sub-therapheutic doses, although there is a controversy on its impact on human health. Previous results showed that Aloe vera gel could improve feed efficiency in broilers and an in vitro study showed that the extract have an antibacterial effect. Therefore, a further experiment was designed to study the response of broilers to Aloe vera gel or its extract as feed additives. Aloe vera was prepared in dry gel or chloroform-extract and included in the diet at levels of 0.25; 0.50 and 1.00 g/kg (equal to dry gel). Standard diets with or without antibiotic were also formulated as control and a commercial diet was included for comparison. The diets were fed to broilers from day old to 5 weeks. Each treatment has 9 replicates and 6chicks/replicate. Parameters observed were: feed consumption, weight gain and feed convertion ratios. Carcass yield, abdominal fat levels, relative weight of liver, gizzard, tractus digestivus and length of tractus digestivus were also measured at the end of feeding trial. The results showed that Aloe gel and its extract did not influence body weight gain and feed consumption of broilers significantly (P>0.05), but improved feed convertion slightly (3.50%). The response in this trial was similar as thosecommercial diet and diet added with antibiotic. There was no significant (P>0.05) effect of Aloe vera bioactives on carcass yield, abdominal fat level and relative weight of liver. However, Aloe vera gel and its extract tend to increase gizzard weight, gastro intestinal weight and length. The Aloe vera gel and its extract also reduced the total count of aerobic bacteria in the digesta of tractus digestivus. It is concluded that the Aloe vera gel improve feed efficiency in broilers by increasing the size of tractus digestivus and reducing the total count of aerobic bacteria in the gastro intestinal tract.

The experiment has been conducted to determine the nutritive value of palm oil sludge fermented with A. niger added with different sources of phosphorus (NPK, P2O5, NaH2PO4). The experiment was assigned in a factorial (3x3) design. The main factor was sources of phosphorus, while the sub factor was time of incubation (0, 4 days aerobic incubation, and 4 days aerobic incubation followed by 2 days anaerobic incubation). Parameters measured were pH, soluble nitrogen, true protein and crude protein, total Î±-amino acid (TAAA), soluble phosphorus and total phosphor, in vitro dry matter (DCBK), and true protein digestibilities (DCP). Results from the analyses showed that fermentation increased the contents of soluble and total P, protein and TAAA and the value of in vitro protein digestibility. Fermented product added with P2O5 had the highest in vitro dry matter digestibility, while the one added with NPK had true protein content and digestibility. It was concluded that additional NPK gave the best result interm of nutritive value. Â Key words: Palm oil sludge, A. niger, phosphorus sources

A study on the use of Zinc bacitracin antibiotic (ZnB) and dried Morinda citrifolia waste as feed additive in broiler ration was conducted. Two hundred and sixteen day old chicks (DOC) was allocated into 4 treatments: control; control + 50 ppm ZnB, and control + M. citrifolia waste at 2 levels (5 and 10 g/kg ration) with 9 replications. Each replicatation consist of 6 birds. The treatments were allocated in a completely randomized design. Variables measured were feed intake, live weight, feed conversion ratio (FCR), percentages of carcass and internal organs (liver, gizard, abdominal fat, and thickness of intestine). The results showed that feed intake ofÂ M. citrifolia waste was significantly (P<0.05) lower than that of control. Live weight and live weight gain of M. citrifolia waste treatments did not significantly different (P>0.05) from that of control. The use of M. citrifolia waste (5 and 10 g/kg) gave significantly lower (P<0.05) live weight than the use of antibiotic. FCR of M. citrifolia waste 5 g/kg ration and antibiotic was not significantly different (P>0.05), but was significantly lower (P<0.05 ) than that of control and M. citrifolia waste 10 g/kg. Carcass and internal organ percentages were not effected by antibiotic and M. citrifolia waste. Liver percentages with M. citrifolia waste 10 g/kg was significantly (P<0.05) higher and abdominal fat was lower (P>0,05) than that of control, control + antibiotic ZnB and M. citrifolia waste 5g/kg. It is concluded thatÂ the supplementation of M. citrifolia waste (5 g/kg) could substitute ZnB to improve feed eficiency in broiler ration. Key Words: M. Citrifolia Waste, Performances, Broiler

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.

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. Â Key words : Palm kernel cake, fermentation, broilers

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.
