MORTALIDADE EMBRIONÁRIA E FETAL EM SUÍNOS: UMA REVISÃO

Abstract

O numero de leitoes desmamados/femea/ano e um dos principais indices de avaliacao da produtividade dentro de uma granja de suinos. Dessa forma, como a gestacao e considerada a fase mais critica da suinocultura, exige cuidados e assistencia constantes, para garantir o sucesso em todo ciclo produtivo. Em contrapartida, existem muitos fatores que podem causar a perda de embrioes e fetos. Diante disso, essa revisao tem como objetivo expor os principais aspectos relacionados a mortalidade embrionaria e fetal em suinos. A mortalidade embrionaria ocorre ate os 35 dias de gestacao, resulta em absorcao dos embrioes e pode ter causas multiplas. A mortalidade fetal e aquela que ocorre apos os 35 dias de gestacao, quando ja se iniciou a ossificacao dos conceptos. Quando ocorre dos 35 ate os 90 dias, os fetos sao considerados mumificados e aqueles que morrem apos os 90 dias sao denominados natimortos. As causas de mumificacao e natimortalidade podem estar relacionadas com a matriz, com o ambiente e com a presenca de agentes infecciosos causadores de doencas reprodutivas. Dessa forma alguns fatores que tem influencia sao: maior ordem de parto, leitegadas grandes e com baixo peso e partos prolongados. Com relacao aos agentes infecciosos, os principais sao o Parvovirus e a Leptospira. Manejo correto dos animais, medidas sanitarias e de biosseguridade sao medidas adotadas para controlar os indices de mumificacao e natimortalidade.
