The objective of this study was to evaluate the phenotypic lactation curve of crossbred dairy cows raised in Phetchaburi and Prachuap Khiri Khan Provinces. Monthly sampling of daily milk yield of 5516 records from 485 first lactating heifers collected by the Biotechnology in Livestock Production Division Department of Livestock Development during the year 1997 to 2003 were used in this study. Monthly sampling of daily milk yield were fitted using Wilmink function (yt=a+bt+cexp-0.05t) to describe the whole and individual curves and estimated lactation parameters (a b and c). All parameters were used to calculate milk yield at day 60 (MY60) 280 (MY280) peak yield (PM) and accumulated 305 days yield (MY305). The results showed that the fixed effects of herd-year-season of calving level of HF blood or genetic provinces and age of calving were significant differences of all traits (P<0.05; a b c MY60 MY280 PM และ MY305). The phenotypic correlations between the considering traits were significant differences (P<0.05). Moreover the study on the nature of lactation curve could describe the lactating abilities and it could represent the others important traits in lactation curve. Therefore these results could guide the farmers to manage their farm and feeding the cattle to be more effective.

The objective of this study is to upgrade the quality of community product manufacturers in Kamphaeng Phet province to the national and international level of the standard for community products by using a knowledge implementation workshop promoted its processing and standard specification followed up by sample screening test of Thai FDA certified or none products; and then qualified each screened sample quality for the standards for community products by Thai Industrial Standards Institute. The result of this study revealed that the dry fish chili paste fry tapioca butter aloe vera in syrup mushroom fermented soya milk cookies noodle and chili paste which must be improved is aflatoxin sorbic acid the definition and scope of products Staphylococus aureus moisture content benzoic acid water activity respectively. Screening test showed net weight measurement and product labeling problems. The product information which met the standards could be applied for the standard quality of community product in Kamphaeng Phet province and upgraded to the quality of community product to food safety and food security.

Dust is a major problem to effect of health especially in formal sector that is not covered by health benefits. This study was proposed at investigating the total dust and particulate matter (PM10) of workers in Thumley Teptaro Wood Handicraft industry Trang Province. Survey and sampling of dust from all operators were collected three replications using a tracking ID on working period. The results showed that were two groups of Thumley Teptaro Wood Handicraft industry that total dust were 7.7540+1.3110 and 14.4162+0.9265 mg/m3 and PM10 were 8.6134+1.4806 and 4.5279+0.8743 mg/m3 respectively. Total dust and PM10 were significant difference (P<0.05). PM10 in the wood product process of Thumley Teptaro Wood Handicraft industry were 3.3422+0.6685 2.9630+0.3050 and 4.5279+0.8743 mg/m3 in sawing frog style and polishing respectively. This result indicated that total dust and PM10 in all production process of Thumley Teptaro Wood Handicraft were not exceed the standard of Occupational Safety and Heath Administrstion and the notification of Interior Ministry about safety environment in workplace. Working behavior was found that workers were affected by total dust and PM10 in wood production process. All workers used dust protector during operators work.

Gac fruit healthy fruit contains many antioxidants such as beta-carotene lycopene. Traditional process by boil reduces antioxidants. The purpose of this study is to process gac juice mixed passion fruit juice by microwave. The optimum formulation from consumer tests were done with 50 juice preferred consumer show that the average like is 3.90 point (5 point). The study used the 3X2 factorial in CRD with 600 700 and 800 watts and at 45 and 55 sec. Analyzed color amount of beta-carotene lycopene pH and microorganisms showed that 700 watts at 45 sec. gave the highest level of beta-carotene contents at 38.11 ?g/g. The comparison between the gac juice mixed passion fruit juice through boiled process and the gac juice mixed passion fruit juice through microwave process was investigated. The content of beta-carotene and lycopene of juice through microwave process was than 2.43 and 1.59 times respectively.

This research presents a study of the compressive strength porosity chloride penetration resistance to carbonation and corrosion of self-compacting concrete containing fly ash ground rice husk-bark ash and ground bottom ash. Portland cement (CT) is partially replaced with pozzolans 0-40% by weight of the cementitious materials. Fly ash ground rice husk-bark ash and ground bottom ash have a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of self-compacting concrete improves substantially with partial replacement of Portland cement with fly ash. Self-compacting concrete mix cement containing 20-40% of pozzolans can be used to make cementitious materials. The use of fly ash ground rice husk-bark ash and ground bottom ash produces concrete mix with good strength and resistance to chloride and corrosion.
