    The experiment was conducted to study the effectiveness of dried milky sludge (DMS) as a feed source for laying Japanese quails. The DMS was incorporated into the experimental diets at levels of 0, 5.0, 10.0, 15.0 and 20.0%. Four hundred quails were used in a completely randomized design. The results revealed that the daily egg-laying rate, feed cost/100 egg weight, egg width, egg length, egg weight, shell quality characteristics in terms of breaking time, Young's modulus, work, max force, fracturability, breaking stress, stiffness and power, as well as color intensity and yolk height improved significantly with increasing levels of DMS in the diet (P < 0.05), while feed intake/bird/day, mortality and eggshell thickness showed no significant differences (P > 0.05). From this experiment, it was found that DMS incorporated into the experimental diet at the 20.0% level yielded the most productive performance and best egg quality. © 2009 Japanese Society of Animal Science.

    The aim of this work was to study the optimal conditions for anthocyanin extraction from natural plant materials in order to develop a pH test kit. The plant materials used were butterfly pea flower (BPF), roselle red flower (RRF) and dragon fruit peel (DFP). The solvents used in this study were distilled water, 1% HCl/95% ethanol (HE), 0.1 N acetic acid, 0.5% vinegar and 20% white liquor. A plant materialto- solvent ratio of 5: 50 (w/v) and an extraction time of 2 h were employed. The result shows that BPF could produce the highest average yield of anthocyanins, and that HE was the optimal solvent. Anthocyanins from the BPF+HE extract yielded the best properties for buffers in various pH, produced easily classifiable pH ranges, and were the most suitable to develop a pH test kit. In conclusion, the pH test kit developed by this method can be used for effluent measurement and will provide results similar in term of accuracy to those produced by a commercial pH test kit and a field pH meter. © 2011 Academic Journals.

    Wolffia arrhiza meal (WAM) was evaluated as a protein replacement for soybean meal (SBM) in the diet of laying Japanese quails. A total of 480 4-week-old laying quails were randomly allocated to form six groups in a completely randomized design. Each group contained four replicates, with 20 quails per replicate. WAM was incorporated into the diets at levels of 0, 4.00, 8.00, 12.0, 16.0 and 20.0%. The results showed that feed intake per bird per day, daily egg-laying rate, feed cost per 100 egg weight, egg width, egg length, egg weight, eggshell thickness, yolk height and shell quality characteristics in terms of breaking time, Young's modulus, work, maximum force, fracturability, breaking stress, stiffness and power showed no statistically significant differences (P > 0.05) among the 0 to 16.0% levels of WAM. However, these performance measures were significantly lower with 20.0% WAM in the formulated ration (P < 0.05). Mortality showed no significant differences among dietary treatments (P > 0.05). The color intensity of the yolk increased as SBM was replaced with increasing amounts of WAM (P < 0.05). In conclusion, WAM could be successfully used in place of SBM. However, the amount used should not exceed 16.0%. © 2012 Springer Science+Business Media B.V.

    Biochars can be used as soil amendments for improving soil properties and crop yield. The objective of this research was to study the plant growth, yield, yield components, and seed quality, including nutrients and heavy metals (Pb, Cd, and Hg), in the soybean plant (Glycine max [L.] Merr.) and soil. The experiment was conducted from September 2010 to January 2011 in a greenhouse located in the Dan Khun Thot District, Nakhon Ratchasima Province, Thailand. The research comprised six treatments with four replicates in a completely randomized design. Quail litter biochar (QLB) at rates of 0, 24.6, 49.2, 73.8, 98.4 and 123 g per pot mixture were provided to soybean cv. Chiang Mai 60. The results showed that QLB could be used as a soil fertility improvement and amendment for soybean production with an optimum rate of 98.4 g per pot mixture, which gave the best performance in terms of the number of nodes, height, DM accumulation, total yield, and seed quality. After the experiment, the nutrient contents in the soil increased as the QLB content increased, but the heavy metal residues in the leaves and seeds did not change. However, QLB at levels higher than 98.4 g per pot mixture is not advisable because QLB is alkaline in nature, which may affect soil pH.
