【摘要】 家禽因其眼球微结构的特征,对光照的刺激十分敏感,因此在实际的生产养殖中,通过人工控制光照条件来促进家禽生长,以达到经济效益最大化。目前,在节能减排的时代背景下,在家禽养殖中,白炽灯正逐步退出历史舞台,LED因其节能作为热点替代光源之一。更为重要的是,LED对自身光因子的可调控性使得它在家禽养殖应用中能够满足家禽对光的特性需求。本论文以“梅黄”肉鸡为研究对象,比较研究了在封闭环境下5种LED光色对肉鸡生产性能的影响,并进一步对比试验了在封闭环境与半封闭环境下优势LED光色的不同补光时长对肉鸡生长生产性能的影响。本文主要的研究内容和成果如下：(1)研究了封闭环境下白、红、黄、绿、蓝5种LED光色(光照16h：黑暗8h)对肉鸡生产性能的影响。研究表明,LED黄光更能促进“梅黄”肉鸡的生长,提高其生产性能。(2)重点研究了半封闭环境下,白天自然光照射12h,封闭饲养环境后LED黄光补光0h、2h、4h、6h、8h、10h、12h七种时长对肉鸡生产性能的影响。实验中发现,Y2h的补光方式能够较好的促进肉鸡生长增重,即能更好的促进“梅黄”母鸡的生长。(3)重点研究了封闭环境下,优选光色LED黄光光照12h、14h、16h、18h、20h、22h、24h七种时长对肉鸡生产性能的影响。结果显示,Y22h的人工补光时长能够得到较大的体重,较好的屠宰性能,较低的单鸡料肉比。更多还原

【Abstract】 Poultry are very sensitive to light because of micro-structure of their eyes. Controlling the illumination conditions properly would promote the growth of poultry and maximize the profit in actual production conditions. Incandescent lamps, which have been widely used, are phasing out in poultry breeding with the implementation of policy on energy-saving and emission reduction. Whereas, lighting emitting diode (LED) are more controllable and more energy-saving, so LEDs become the most prospective light source in place of Filament lamps." Meihuang" broiler was studied in this research,five different LED colors were used to compare the influence on productive performance in a closed environment, the best LED color in previous research was studied further to get better lighting treatment to effect on broiler growth performance in a closed and semi-closed environment.In this paper, the main research contents and results are as follows:1. LED with 5 colors (white,red, yellow, green, blue, warm white) were chosen in this research to study the effect of different kinds of lighting colors on productive performances of broilers. Results indicated that Yellow LED performed best.it can promote the growth and improve the production performance of "Meihuang" broiler.2. Mainly study in the semi-closed environment(12h light during the day. Oh.2h. 4h,6h,8h, 10h,12h Yellow LED fill light at night), seven lighting treatments affect the performance of poultry production.Found in the experiments, the Y2h fill light mode can better promote the growth of poultry to put on weight, which can better promote the growth of "Meihuang" broiler.3. Mainly study in the closed environment(12h,14h,16h,18h,20h,22h,24h Yellow LED fill light during one day), seven lighting treatments affect the performance of poultry production.Found in the experiments, the Y22h fill light mode can better promote the growth of poultry to put on weight, which can better promote the growth of "Meihuang" broiler.更多还原
