Riboflavin binding protein was purified from the egg yolk of Aquila hastate (Eagle). The protein was purified using DEAE Sepharose ion exchange chromatography followed by gel filtration on Sephadex G-100. The purity of the protein was judged by cylindrical and slab SDSPAGE techniques. Comparison of the mobility of RfBP with that of the standard molecular weight marker protein revealed that the ...

A quantitative analysis of NMR proton relaxation in hen egg albumen and yolk is undertaken to research the causes of quality loss during the first few days of storage and to access the feasibility of an on-line NMR sensor of internal egg quality. It is shown that the change in the transverse relaxation in thick egg albumen mainly results from an increase in proton exchange rate resulting from a...

BACKGROUND Evidence showed that the occurrence of iodine deficiency endemic areas has been found in every provinces of Thailand. Thus, a new pilot programme for elimination of iodine deficiency endemic areas at the community level was designed in 2008 by integrating the concept of Sufficient Economic life style with the iodine biofortification of nutrients for community consumption. METHODS A...

An experiment was conducted with Hy-Line W-36 hens to evaluate the Val requirement in a corn-soybean meal diet. Eight experimental diets were fed with Val levels of 0.700, 0.665, 0.630, 0.595, 0.560, and 0.525%. A positive control (0.765% Val) was fed. Egg production (EP) was increased by addition of Val to 0.630%. Egg weight (EW) was increased by addition of Val to 0.655%. Broken-line regressi...
