dc.description.abstract母豬生產受到許多因素如環境、營養、遺傳與經濟等之影響,為了獲得更高的利益,瞭解各個因子之間如何影響母豬生產性能極為重要。因此,本研究之目的在設計可模擬母豬在不同飼養管理組合下的繁殖狀況之線上模式。系統採用Microsoft Windows Server 2003作業系統,運用ASP.NET 2.0 (Active Server Pages.NET)程式語言結合Microsoft Access 2007資料庫,建置在國立中興大學動物科學系的伺服器上。主要架構分為建立使用者資料、模擬模式、使用說明、相關網站與聯絡程式設計者等五項。使用者經過線上註冊即可登入本系統,隨後輸入母豬資料、飼糧組成、飼養策略、畜舍環境與成本項目。本模式以每日為基礎,預測母豬在不同繁殖週期中不同階段之飼料採食量、背脂變化、體重變化、維持與利用之能量所需、以及懷孕期間胎兒發育情況;並預測泌乳期間泌乳量及仔豬生長情況等,另產生一份財務報表,藉此評估各項有利飼養工作之策略。本系統提供的資訊可供做養豬業者飼養豬隻時之決策參考。zh_TW
dc.description.abstractSow production efficiency is the result of many distinct but interacting factors including environment, nutrition, genetics, and economics that act during both the growth period and the reproductive life of the pig. It is very important to understand the factors affecting the performance of sow to get more profit. Therefore, the purpose of this study was to build an online simulation model for sow reproduction at different feeding and management environment. This system was designed by adopting Microsoft Windows Server 2003 as operation system and was written with ASP.NET 2.0 (Active Server Pages.NET) coordinated with Microsoft Access 2007 Database. This system was installed on the Server of the Department of Animal Science, National Chung Hsing University. The main functions include five sections in terms of user data, simulation, operation instruction, reports, and contact programmer. First step, user must register online before login this system. Subsequently, user must input the sow data, feed details, feeding regimes, house environment, and the cost of the project. The system was then predict the sow's voluntary feed intake, backfat thickness changes, daily weight gain, and energy needs at each day of different reproductive cycle. At the same time, system also predicted fetus growth at gestation, milk yield and piglet growth at lactation. A financial statement was also produced to assess the favorable work of the feeding strategies. Some useful information from this system could act as decision support system for farmers to manage their sows.en_US
