Resumo: |
This research was accomplished with the objective of studying the population density in laying and her influence in the aspects zootecnics and economical. 264 laying were housed in cages with dimensions of 100 cm x 50 cm x 40 cm in delineament entirely casualizado, with four groups distributed in factorial outline 4x4, with 8, 10, 12 and 14 birds, corresponding to 625, 500, 416,6 and 357,14 cm2/ave. The appraised characteristics were: production of eggs, medium weight of the eggs, ration consumption, mass of the eggs, alimentary conversion for dozen and eggs doesn't conform. Our results just showed significant effects of the density in the cage for the egg extra type and second and in the daily production of the eggs type second, not influencing in the other studied variables. Based on our results ended that for laying of the lineage Dekalb White, the use of cages with the population density of 625, 500, 416,6 and 357,14 cm2/ave in the production phase don't harm the quality parameters under the aspects zootecnic and economical. |
