【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。
[Abstract]:Poultry is sensitive to light stimulation because of the characteristics of the microstructure of its eyeball. Therefore, in actual production and breeding, the light condition is controlled artificially to promote the growth of poultry in order to maximize the economic benefits. At present, under the background of energy saving and emission reduction, incandescent lamps are gradually withdrawing from the historical stage because of their energy saving as one of the hot alternative light sources in poultry farming. What is more important is that LEDs can meet the demand of light characteristics in poultry breeding applications because of their ability to regulate their own light factors. In this paper, the effects of five kinds of LED light color on the performance of broilers under closed environment were studied by using "Muihuang" broiler as the research object. Furthermore, the effects of dominant LED photochromatic time on the growth performance of broilers in closed and semi-closed environments were compared. The main contents and results of this paper are as follows: 1) the effects of white, red, yellow, green and blue LED light (16 h: dark 8 h) on the performance of broilers under closed environment were studied. The results showed that LED yellow light could promote the growth of "Mei Huang" broiler and improve its production performance. It was found that the light supplementation of Y2h could promote the growth and weight gain of broilers, that is, it could promote the growth of "Mei Huang" hens. The effect of LED yellow light on the performance of broilers was studied in this paper. The effects of light on the performance of broilers were studied in the following seven periods: 12hh, 14h, 16h, 18h, 20h, 22h and 24h, respectively. The results showed that the artificial light supplementation time of Y22h could get the higher body weight, better slaughtering performance and lower feed / meat ratio of single chicken.
