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.

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.
