| 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. |
