The objective of this research was to study the dominant feature of Khao Wong glutinous rice Kalasin province for geographical indications. The effect of three cultivated areas of glutinous rice variety (RD6) consisting of Khao Wong Huai Mek and Kong Chai districts was investigated along with their physicochemical textural properties and thermal properties. For the effect of different cultivated areas on glutinous rice properties the significant effect of different cultivated areas on chemical compounds viscosity and textural properties was observed (p?0.05). There was no significant effect of cultivated areas on amylose content (p>0.05). The highest protein and ash contents and the lowest setback hardness and chewiness values were found in the sample cultivated in Khao Wong district area. The aroma compounds analysis of rice samples revealed that methanecarboxylic acid was observed in glutinous rice cultivated in all studied areas. Whereas the highest content of 122-Trimethylcyclopropylamine was found in the sample cultivated at Khao Wong and Kong Chai districts. In addition the highest content of 2-cis-9-octadecenyloxyethanol was observed in glutinous rice cultivated at Huai Mek district.

These researches were to determine the preparing and drying on physical and chemical properties of germinated khaohang rice from KDML105. Two factors on study were preparing germinated khaohang rice (chill at 5 oC and frozen -20 oC) and drying method (tray drier and infrared drier). The results on expansion (%) and texture of cooked rice found that there were not significant influence interaction and two main factors. But main factor on infrared drying method were affected to the highest head rice yield (%) and lowest on Chroma (C*). As same as gamma amino butyric acid (GABA) had the highest 23.37 (mg/100g) and preparing germinated khaohang rice had between 20.50 to 22.21 (mg/100g). The pasting properties reducing sugar total phenolic scavenging activity of DPPH free radical (%) and resistance starch were significant influence interaction.

This research aimed to develop a flock of Thai indigenous chicken namely Chee with pure white feather in order to meet the requirement of domestic consumption and export of meat chickens. The genetics on growth must be improve with egg production was no affected. The selections were continuously done for 5 generations. Each generation 30 sires and 50 of 16 week old females were obtained. At suitable age 6 weeks after first egg laid the artificial inseminations were arranged twice weekly with 1: 5 of the male and female proportion. Eggs were collected to hatchery in the 3 consecutive weeks followed with the 2 week skips. Before the next AI of reciprocal cross the 3 groups were bred and 3 generations each. The newborn chickens from hatchery of each generation were weighed and the other measurements were done at the 4 weeks intervals. The data of weights at 16 week old chickens and breast widths were used to calculate for breeding value. The BLUP (Best Linear Unbiased Prediction) was a selection tool to select high selection index for replacement herd of each generation. For the females the 300 day egg productions were added. It was found that from the 1st to the 5th generation the average of 16 week old chickens were 1225.99 1265.86 1461.94 1326.16 and 1439.36 gram respectively. The average body weight gain was 213.37 gram and the average daily gain was 12.85 gram. The 16 week breast widths were 5.46 5.90 5.54 5.56 and 5.65 centimeter respectively. The ages of first egg laid were 211.30 178.66 175.83 171.91 and 171.10 day respectively. In the 5th generation egg production started about 40 days earlier than the 1st generation. The first egg weights were 1390 1426 1467.61 1446.33 and 1529 gram respectively. Egg productions at the 300 day old were 36.38 38.28 40.29 42.42 and 45.58 eggs and it could provide 9 eggs more than 1st generation.
