Abstract In this study, the composition of chicken eggs from diets with various lutein levels was examined. This study involved a total of 120 laying hens. Treatments included lutein-free rations and lutein concentrations of 20, 40, 60, and 80 ppm. Each treatment was applied a total of eight times. Chickens are kept in cages with access to feeding and drinking areas. The analysis of the research data was conducted utilizing a completely random design. The parameters that were measured were the egg’s weight, its yolk, and its albumen. The components of eggs fed various dietary levels of lutein from marigold extract had not been significant (P>0.05) on all egg components stored for one day. However, the treatment had a significant impact (P<0.05) on the albumen index stored for 14 days, and the yolk to albumen ratio and albumen index for eggs stored for 21 days. This study concludes that for optimum albumen weight and index and the ratio of yolk and albumen stored for 14 and 21 days, a dose of 20 and 40 ppm in the diets is sufficient.

Palm polysaccharides were believed to contain mannose monosaccharides that are beneficial as an antibiotic replacer for poultry. This experiment was conducted to study the effect of coconut and salak polysaccharides on growth performance, excreta dry matter, digestibility, and bursa of Fabricius weight of E. coli challenged broilers. A total of 140-day old unsexed broiler Cobb chicks were used as experimental birds for 4 weeks. During the first week, the chicks were allocated in five brooder pens and transferred into 20 pens on day 8. The broiler chicks were offered 5 different experimental rations. The rations were control basal diet (T1), basal diet added with antibiotic avilamycin (T2), basal diet added with commercial yeast oligosaccharides (T3), basal added with coconut polysaccharides (T4), and basal diet added with Salak (snake fruit) polysaccharides (T5). To protect the birds from New Castle diseases, vaccination was done on day 3. On day 14, the birds were challenged against E. coli for three consecutive days. Plastic feeders and drinkers were put in the pen. The experiment used a completely randomized design with five different rations, four replicate pens of 7 birds each. The data were subjected to the analysis of variance. Any significant differences detected in the variance analysis were then tested with the least significant difference test. Results indicated that after challenged with E. coli, birds fed the basal diet had lower body weight gain, mortality, excreta dry matter, and carcass percentage, but higher in FCR and bursa of Fabricius weight than the birds fed T2, T3, T4, and T5 diets. Feed intake of the E. coli challenged broilers were lower than those of broilers fed the T3 diet. Feed digestibility was not affected by the treatment diets. In conclusion, the addition of feed additives either antibiotic or palm polysaccharides could enhance the growth performance, carcass percentage, and excreta dry matter of the E. coli challenged broilers.

Fermentation has been practised in feed technology to bioconvert the inorganic minerals to organic compounds. A study was done to determine the effect of Saccharomyces cerevisiae fermented coconut dregs with the addition of selenium on growth performance, feed digestibility and the intestinal response of broiler chickens. The study used 112-day old unsexed broiler chicks for 6 weeks. The broilers were fed with 4 different experimental diets. The diets were basal diet (T1), basal diet plus 0.5% coconut dregs (T2), basal diet plus 0.5% of 5 days fermented coconut dregs (T3) and basal diet plus 0.5% of 7 days fermented coconut dregs (T4). The broilers were fed ad libitum and tap water was offered at all times. The broiler chicks were vaccinated against New Castle Diseases on the fourth day. Feeders and drinkers were placed inside the pen. The feeders, drinkers, pens and surroundings were cleaned whenever necessary. A completely randomized design was used in this study with four different treatment diets, four replicate cages of 7 birds each. The data found in this study was analyzed using an analysis of variance. A Tukey test was applied once a significant effect was detected in the analysis of variance. Results of the study indicate that body weight gain and dry matter digestibility increased when the birds were fed the diets T3 and T4. The relative gizzard weight of birds fed the T3 and T4 was lighter than the birds fed the T1 and T2. Feed intake, feed conversion ratio, carcass percentage and relative intestine weight were not affected by the experimental diets. In conclusion, feeding the birds with diets supplemented with Saccharomyces cerevisiae-fermented coconut dregs with additional selenium improved feed quality and broiler performance.

The low quality of palm kernel meal (PKM) is due to the presence of high fibrous fraction. Fermentation of a low-quality feedstuff by using fungi could improve its quality. An experiment was done to determine the effect of fungi fermented palm kernel meal on the performance of broilers. Palm kernel meal was fermented by different fungi (Aspergillus niger, Trichoderma viride and Pleorotus ostreatus). The study used 200-day-old chicks and the chicks were randomly placed in brooder cages. The broilers were fed with starter and grower diets from days 1 to 21 and days 21 to 42 respectively. Feed and water were provided ad-libitum. The treatments diets were R1: basal diet (0% PKM), R2: (10% PKM), R3: 10% Aspergillus niger fermented PKM, R4: 10% Pleorotus ostreatus fermented PKM, R5: 10% Trichoderma viride fermented PKM, R6: 20% PKM, R7: 20% Aspergillus niger fermented PKM, R8: 20% Pleorotus ostreatus fermented PKM, R9: 20% Trichoderma viride fermented PKM. A completely randomized design was used in this study. Data were analyzed by the analysis of variance. The inclusion of 20% PKM in the diet decreased body weight gain and feed intake. Supplementation of the diets with 20% fungi fermented PKM could maintain body weight gain to the same level of those birds fed the basal diets. The percentage of gizzard weight was higher in birds fed the basal diet than the other treatment birds. In conclusion, fermentation of PKM with Aspergillus niger, Trichoderma viride and Pleorotus ostreatus could improve its quality. The performance of broilers fed the 20% PKM could be maintained provided.

The low quality protein of coconut meal, coupled with high fibre content, leads to limited use of this agricultural by-product in the poultry diet. Attempts to maximize the amount of coconut meal included in the broiler feed have been made through amino acids supplementation, enzyme addition and pelleting coconut meal. Among these feed technologies and manipulation, pelleting coconut meal appears to be more powerful in promoting the growth of broiler chickens. The reasons for the improvement of broiler growth due to pelleting coconut meal have not been established yet. The mechanisms of improved growth of birds might be through increased feed intake, less energy spent and increased bulk density. Coconut meal contains a high concentration of mannose – based polysaccharides or mannan. This substance has long been believed to have prebiotic properties due to its capability to bind certain species of pathogenic bacteria in the digestive tract of birds. Voluminous reports of the positive effects of mannose-based polysaccharides from yeast have been published. Mannose –based polysaccharides from legumes, on the other hand, have been reported to have anti-nutrient property. Surprisingly, mannose-based polysaccharides from coconut behave like yeast mannan. A number of current studies indicated that mannose based polysaccharides improved body weight gain and feed digestibility. The growth of birds was negatively impacted when the birds were challenged against pathogenic bacteria of E. coli. Wet droppings and diarrhea incidences were not found in E. coli-challenged birds when the diets were supplemented with coconut mannan. In conclusions, coconut meal can be used as a feed ingredient for poultry unless the coconut meal was pelleted or enzymatically treated. Mannose-based polysaccharide from coconut was effective to promote growth and acted as prebiotic.

This study was conducted to determine the effects of the fermentation duration of coconut dregs (CD) by Saccharomyces cerevisiae and the addition of ammonium sulfate on the growth performance, feed digestibility, carcass, and digestive organ developments. A finely ground CD was autoclaved at 20 psi for 20 minutes and added distilled water to meet 80% moisture content. The autoclaved substrate was added with different concentrations of ammonium sulfate and fermented with Saccharomyces cerevisiae to produce Saccharomyces cerevisiae-fermented CD. A total of 192 day-old-unsexed Cobb broiler chicks were used and kept for 6 weeks. The birds were fed experimental diets ad-libitum. The experimental diets were produced by two durations of fermentation (5 days and 7 days) and three levels of ammonium sulfate (0%, 0.2%, and 0.4%) in 4 replicates. The experimental diets were offered ad-libitum and water were available at all times. Fermentation decreased lipid and crude fiber content of CD and the addition of ammonium sulfate increased protein content and amino acid concentration of CD. The bodyweight gain of birds increased when the CD was fermented for 5 days and with the addition of 0.2% ammonium sulfate. Dry matter digestibility and protein digestibility were improved when CD was added with 0.2% ammonium sulfate. In conclusion, fermenting CD for 5 days increased body weight gain and the addition of 0.2% ammonium sulfate improved the feeding value of the diet and growth of birds.

The uses of a prebiotic to replace antibiotic growth promoters, mycotoxin and cholesterol binders in broiler diets have been commonly practiced over the last three decades. Many products have appeared commercially to replace antibiotic growth promoters and to tackle the problems of mycotoxins contamination. Mannose-based carbohydrates, particularly mannan-oligosaccharides from yeast, appear to have properties of coping with the mycotoxin related problems. Over the last three years, studies on the use of copra-mannan (CM) in this respect have produced promising results. CM has been found to effectively improve bird performance. When the birds were challenged against Escherichia coli, the supplementation of the feed with CMs was able to maintain growth performance of birds to the same level as the growth of birds fed commercial mannan-oligosaccharides or antibiotics. Contamination of feed with 0.3 ppm aflatoxin B1 reduced feed digestibility, but not when the feed was mixed with CM. The supplementation of the diet with CMs protects the birds from wet droppings when the birds were challenged by either Escherichia coli or aflatoxin contamination. Since there is a conflicting information about using mannans in the diet, particularly between using legume mannans as an antinutrient and yeast mannans as a pronutrient, this paper reviews the potential use of CMs for the purposes of promoting growth and improving health status of broiler chickens.
