SPACIAL ILLUMINANCES VARIABILITY AND ENERGY CONSUMPTION IN AVIARIES FOR LAYING HENS EQUIPED WITH COMPACT FLUORESCENT LAMPS AND LIGHT EMITTING DIODE REA
Ribeiro,Priscilla A. P.; Yanagi Junior,Tadayuki; Oliveira,Daniela D. de; Ferraz,Gabriel A. E. S.; Lourençoni,Dian.
ABSTRACT The spatial illuminance distribution interferes in the commercial production of eggs and electric energy consumption, being considered the second major source of costs in the production chain. Therefore, in this study the objective was to evaluate the spatial distribution of the illuminance level and electric energy consumption in two commercial aviaries for egg production. The first aviary was equipped with compact fluorescent lamps (CFL) and the second, with light-emitting diode (LED) lamps. The illuminances in the aviaries were analyzed using descriptive statistics and their spatial distribution through geostatistics. It was found that the aviary equipped with CFL showed better uniformity in the illuminances distribution and better results in...

Morphostructural Characteristics of Three Varieties of Greybreasted Helmeted Guinea Fowl in Nigeria International Journal of Morphology
Fajemilehin,S. O. K.
Three hundred eggs were obtained from settlements around New Bussa, Niger state during the month of August 2006 and transported to Ekiti state by road. 93.33 % of the three hundred (300) eggs collected were selected for hatching. The eggs were hatched at the aviary unitof Ekiti state Agricultural Development Project, Ikole Ekiti, Nigeria. At hatching the keets were separated on the basis of their plumage colours as shown by the distinct difference in the colour of the downy feathers of the keets into three genotypes, pearl, ash and black. The keets of each genotype were randomly allocated to brooder rooms where they were floor brooded using kerosene stove. The keets were fed with diet containing 24% CP, 3000 kcal/kg ME and water ad libitum for the first 8...

Collection of Coleoptera from a poultry farm in Pelotas, Rio Grande do Sul, Brazil Ciência Rural
Pinto,Diego Moscarelli; Duarte,Juliano Lessa Pinto; Ribeiro,Paulo Bretanha; Silveira Júnior,Paulo.
To evaluate the population fluctuation of Coleoptera from a poultry farm in Pelotas, Rio Grande do Sul, Brazil, two sampling methods were used: a tube-type trap and a sandwich trap. The analyses of polynomial regression were applied independent of the type of sampling method used. The experiment was carried out for twelve months, from April 2002 to March 2003, in a broiler barn aviary at the Conjunto Agrotécnico Visconde da Graça/UFPEL. A total of 43.945 Coleopterans were captured from the following species: Alphitobius diaperinus, Carcinops troglodytes, Euspilotus rubriculus, Gnathocerus cornutus, Mezium americanum and Somotrichus unifasciatus. Among these, Alphitobius diaperinus was present in all months of the year, with larval population peak in...
