 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Genetic Parameters for Birth Weight and Weaning Weight in Anglo-Nubian, Saanen, Thai Native and Crossbred Goats) ผู้เขียน:จิตติมา กันตนามัลลกุล, ดร.พรรณวดี โสพรรณรัตน์, รองศาสตราจารย์ , Monchai Duangjinda, สุวิทย์ อโนทัยสินทวี, ดร.ศรเทพ ธัมวาสร, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractGenetic parameters were estimated for birth weight and weaning weight in Anglo-Nubian, Saanen, Thai native and crossbred goat populations maintained at the Yala Livestock Research and Breeding Center. Records on 2,845 kids descended from 54 bucks and 615 does from 1995 to 2005 were included in the analysis. Analyses were carried out using the DFREML algorithm and fitting four different animal models that included or ignored maternal genetic and permanent environmental effects. In Model 1 only the direct genetic effect was fitted. The maternal permanent environmental effect was added in Model 2, while the maternal genetic effect was added in Model 3. In Model 4, the maternal genetic and permanent environmental effects were included from Model 1. The genetic covariance between the direct and maternal effects was included in Models 3 and 4. The estimates of direct heritability increased when the maternal genetic effect was added with the direct and maternal covariance. The estimates of maternal heritability slightly decreased when the maternal permanent environmental effect was added to the model. The direct-maternal genetic correlation estimates were negative, whereas estimates of the maternal permanent environmental variance as a proportion of phenotypic variance were low. The likelihood ratio test showed that Model 4 was the best for birth weight and Model 3 was the best for weaning weight. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Web-based Information System for Management of Swine Breeding Herd Farm) ผู้เขียน:สราญ ปริสุทธิกุล, นายสุพัตร์ ฟ้ารุ่งสาง, รองศาสตราจารย์ , Monchai Duangjinda, นางอมรา ทองปาน, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA Web-based Information System (WIS) was developed using open source software (Linux Operating System, Apache web server, MySQL and PHP, which are collectively known as LAMP) to assist swine breeding herd management in data recording and tracing, as well as in problem diagnosis. A farm survey was conducted to obtain basic information including problems and farmers’ needs. The existing available computer program was analyzed to design a new system. Programs for data importing, user interface and various reports and graphs, as well as data exporting and database backups were developed. Then, data was tested from the available PigLIVE program used on a farm in Nakornpathom province. The developed WIS was pilot implemented on six farms in Ubonratchatani province. The results of the pilot implementation indicated that WIS could be operated on the Internet, the Intranet or on a stand-alone computer. In addition, it could eliminate the cost of the swine breeding herd management software and the operating system and increase the efficiency of data access on the farm. Based on recommendations from targeted end users, WIS will be updated and expanded to provide an efficient tool for swine breeding herd management in the future. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Algorithms for Calculating the Indices Determining the Production Efficiency of Swine Breeding Herds: Pigs Weaned Per Sow Per Year and Litters Per Sow Per Year) ผู้เขียน:สราญ ปริสุทธิกุล, นายสุพัตร์ ฟ้ารุ่งสาง, รองศาสตราจารย์, Monchai Duangjinda, นางอมรา ทองปาน, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThis research aimed to develop algorithms for calculating some important indices that determine the reproductive and production efficiency of swine breeding herds. Algorithms were developed for litters per mated female per year (LMFY) and pigs weaned per mated female per year (PWMFY). Both algorithms can be used to develop an information system for swine breeding herd management by using open source software. The open source software used in this research was XAMPP for Linux. The data used for testing came from the database of PigLive program from a swine farm in Nakornpathom province. The data consisted of two tables containing details on status and history, with 407 and 6,526 records, respectively. The data was imported into the new system that had been developed using a webbased system. Though the comparison of the indices did not agree exactly with the ones reported from the PigLive program based on monthly periods, the values obtained were similar with the same trends. The algorithm developed had five steps: 1) date management, 2) calculation of production, 3) data management to calculate an average mated female inventory (AMFI), 4) calculation formula and 5) presentation of the results. |
