Research Note: In Ovo Administration of a Competitive Exclusion Culture Treatment to Broiler Embryos

Abstract: Exposure of chicks to salmonellae in the hatchery and hatchery environment limits the effectiveness of a competitive exclusion (CE) culture treatment. Therefore, in an attempt to apply treatment before chicks are exposed to salmonellae, the CE culture was introduced in ovo to unhatched embryos. An undefined, anaerobically grown CE culture, derived from cecal contents of healthy adult chickens, was diluted 1:1,000 or 1:1,000,000 and inoculated either into the air cell or beneath the inner air cell membrane of 1… Show more

“…Few researchers have entertained the idea of administering probiotics in ovo, which recently has been gaining more interest [22,23]. The earliest attempts of connecting these concepts demonstrated promising results where Salmonella typhimurium colonization was reduced in chicks administered an undefined cecal culture of bacteria in ovo [24]. Unfortunately, negative results in terms of hatchability, performance, and mortality have been noted, though these consequences may be attributed to the probiotic strain used and delivery site [22,[24][25][26].…”

Cox et al (1992) A ação de produtos de exclusão competitiva foi constatada em diversos trabalhos, através da redução da colonização por Salmonella spp. em aves (Bailey et al, 1988;Cox et al, 1992;Andreatti Filho et al, 2003).…”

Com o intuito de se antecipar à contaminação por Salmonella spp., alternativas à administração desses produtos logo após o nascimento, como o uso in ovo, estão sendo estudadas (Cox et al, 1992;Edens et al, 1997;Hulet e Meijerhof, 1997).…”
