Influência do aquecimento artificial de ovos de matrizes pesadas sobre o rendimento de incubação

Abstract:  RESUMOO desenvolvimento embrionário nas aves tem início antes mesmo da postura. A variabilidade do estágio de desenvolvimento embrionário no momento da oviposição é conhecida e influencia a taxa de eclosão, uma vez que estágios muito avançados ou muito precoces são prejudiciais por tornarem os embriões mais sensíveis ao estresse do armazenamento. O aquecimento de ovos férteis no período entre a postura e o armazenamento vem sendo estudado como forma de reduzir os efeitos negativos do armazenamento sobre o re… Show more

“…The factors associated with productive outcomes include breeder age, which is of substantial importance for achieving incubation success: it has been proven to be a pre-incubation factor that influences the internal and external quality of eggs (BARACHO et al, 2013;GARCIA et al, 2015;MENDES et al, 2014;TANURE, 2008). As flocks age, egg size increases and eggs undergo changes in shell thickness, as well as in pore quantity and diameter.…”
