Iluminação artificial com LED de diferentes cores na avicultura de postura

Abstract

The work was carried out, the first being conducted with Japanese quail and the second conducted with Bovans White laying hens. With the following objectives: Experiment 1 - evaluate the performance of the reproductive system biometrics, relative weight of the organs of the gastrointestinal (GI) tract and the quality of Japanese quail eggs (Coturnix coturnix japonica) submitted to artificial lighting system with LED light (LED) in different colors to replace the fluorescent lamp. Experiment 2 - assess the quality of egg laying hens subjected to artificial lighting system with LED (LED) Red replacing fluorescent lamp. In the first experiment we used 240 Japanese quail. Four situations were adopted: fluorescent lamps, LED lamps green, red and blue. It was determined the performance characteristics, and reproductive system TGI and egg quality. The performance evaluations were evaluated feed intake, egg production and feed conversion (kg/kg and kg dz). For qualitative analysis it was determined the average egg weight, Haugh unit, yolk index, shell thickness, percentage of albumen, yolk and shell. The data showed effect (P<0.05) on feed intake measured for the different sources and oviduct length for two time periods (57 and 64 days of age). Isolated effect was observed for the different light sources (P<0.05) and evaluated for different periods (57 and 64 days of age) on relative weight of the liver and small intestine. In the second experiment, we used 200 laying hens at 30 weeks of age. Adopted a DIC, with 2 treatments (fluorescent lamps and red LED tapes) of 10 repetitions with 10 birds each. The performance indicators and quality of eggs showed no effect (P> 0.05) between the colors evaluated evaluated light sources.
