Uso de gemas de ovos de aves hiperimunizadas contra Escherichia coli suína no controle da diarréia neonatal de leitões

Abstract: RESUMO -Foi avaliado o efeito das gemas de ovos de aves hiperimunizadas contra Escherichia coli (E. coli) patogênica para suínos sobre a imunidade passiva de leitões recém-nascidos em uma unidade produtora de leitões. Foram avaliados a densidade ótica do ELISA (DO) para anticorpos contra E. coli, o peso corporal e a ocorrência de diarréia diária em 137 leitões recém-nascidos oriundos de 25 fêmeas primíparas, não vacinadas contra E. coli. As porcas foram consideradas blocos. De cada fêmea, foram separados seis … Show more

“…This result confirms that the use of hyperimmunized yolks is a viable alternative to the use of antibiotics, improving piglet health and performance, similar to that shown in newborn piglets (Owusu-Asiedu et al, 2002;Ribeiro et al, 2005;Yokoyama et al, 1992). The study also confirms that the challenge model used was efficient, either through the excretion of E. coli ETEC strains in the PC piglets, or diarrhea occurrence in challenged animals, a consequence of fimbriae viability and virulence.…”

“…In this case, the GLOBIGEN® reduced F18 excretion significantly, indicating that the product has Y immunoglobulins with specific receptors for this fimbria. The product type on the market depends on the type of antigen previously used in the bird vaccination as demonstrated by Ribeiro et al (2005), and this information should be available to users.…”
