Resumo: One experiment was conducted with Hyline W-36 laying hens to determine the influence of feed withdrawal on calcium and phosphorus plasma and eggshell quality. Blood was collected on days 24, 48, 72 and 96h at oviposition and 21h post-oviposition. On the control group, plasma phosphorus was significantly increased from oviposition to 21h post-oviposition. On day two, the group in feed restriction showed higher phosphorus levels 21h post-oviposition. On day 3 and 4, all the values from plasma phosphorus were lower at oviposition and 21h post-oviposition when hens were in feed withdraw. Plasma calcium was not affected during the egg formation in the hens receiving feed “ad libitum”. However, plasma calcium was declined from day 2 to 4 when hens were in feed withdraw. The egg specific gravity and eggshell weight were significantly decreased for hens receiving no feed after day 2.

A retirada de sangue foi realizada no dia 24, 48, 72 e 96h na oviposição e 21h após. No grupo controle, foi observado um aumento no fósforo plasmático da oviposição até 21 horas após. No dia 2 foi verificado um aumento nos níveis de fósforo plasmático, quando a retirada de sangue foi realizada 21 horas após a oviposição, nas aves submetidas à restrição de alimento. A partir do dia 2, todos os valores de fósforo plasmático das aves submetidas à restrição de alimento foram inferiores, tanto na oviposição quanto 21 horas após. Não foi observada flutuação do cálcio plasmático durante o processo de formação do ovo, nas aves alimentadas à vontade. Foi observado um declínio do cálcio plasmático, desde o dia 2 até o dia 4, quando as aves foram privadas de alimento. A gravidade específica dos ovos e o peso de suas cascas diminuíram em relação ao tempo em que as aves permaneceram em restrição de alimento.Editora da Universidade Estadual de Maringá2008-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/251910.4025/actascianimsci.v24i0.2519Acta Scientiarum.
