Effects of Ultraviolet Radiation on Skeleton Development of Broiler Chickens
Effects of Ultraviolet Radiation on Skeleton Development of Broiler Chickens
摘要
Abstract
Seven hundred and twenty one-day-old AA broiler chickens were randomly allocated into two groups (male and female for half), and put into two identical closed houses with different lighting programs. The first house was illuminated by using common incandescence light, and the second one was added with ultraviolet radiation light from the second week onwards. The birds lived in a floor with litters and free access to feed and water. Temperature, humidity and immune programs in the two houses were similar. The results showed that under ultraviolet radiation, the growth speed of skeleton increased (the shank length was significantly increased in the third week, P ＜ 0.05; the leg muscle weight was significantly improved by 3.87%, P ＜ 0.05); the skeleton quality improved (the density of skeleton mineralization was significantly increased by 6.11%, P ＜ 0.01; serum calcium, phosphorus, and alkaline phosphatase activity were all improved); and the growth performance was improved (feed conversion ratio was improved by 1.4% averagely; the uniformity of body weight, the shank length, the inclined body length and body height were significantly improved) in broiler chicken.关键词
