基于个人数字助理的草食家畜饲料配方技术应用研究

Study on Feed Formula Technology of Herbivorous Livestock Based on Personal Digital Assistant

以农户和养殖场饲料配方技术应用需求为重点,在开展详细调查研究的基础上,针对调查中所反应出的需求难点,结合现有技术资源和实现手段,开发完成了基于个人数字助理(Personal Digital Assistant)的奶牛和肉羊饲料配方系统设计,并按照配方系统设计实现了营养标准数据库、饲料原料数据库及配方计算系统进行有效结合,开发出2套基于PDA的饲料配方软件(包含奶牛和肉羊饲养标准数据库各1个,奶牛和肉羊营养知识和饲料原料数据库各1个)。试验对基于个人数字助理的饲料配方与养殖场原有配方的使用效果进行了对比。利用该草食家畜饲料配方软件在4个郊区县31个试验示范点开展技术应用效果研究(其中奶牛20个,肉羊11个)。结果表明:基于个人数字助理的草食家畜饲料配方技术可使奶牛饲料转化效率提高12.20%,肉羊饲料转化效率提高15.80%,每只肉羊育肥期增收40.57元,每头奶牛奶产量提高0.60kg;而且该饲料配方系统具有便携性、操作简单、针对性强的"傻瓜化"技术特点,能够方便快捷被农户所掌握和应用,提高养殖收益并增加收入。

In carrying out a detailed study on the basis of emphasis on feed formula technology of Herbivorous Livestock in farms and livestock farm,for investigations in response to the needs of the difficult points out,the existing technical resources and means,development was based on personal assistant digital feed formula system design of the cows and mutton sheep,according to the formula system design standards for nutrition database,the feed material for the database and the system effectively combined,developed based on two of the pda for software（contains cows and mutton sheep raised the standard database of knowledge about nutrition database of raw materials and food）.The results showed that based on personal assistant of the numbers of livestock feed herbivorous livestock formula will bring cows feed into the efficiency of 12.20%,mutton sheep feed into 15.80% increased efficiency,and each time the sheep fattening income 40.57 yuan.each cow milk production increased 0.60 kg,and the food formula system had the portability and operation simple and clear objective of a technical characteristics of that convenience was the farmers had increased and application,culture and increased income.
