| description | This study aimed to evaluate the incubation performance, the Salmonella Enteritidis capacity of penetration through the eggshell and the ability of colonization of the gastrointestinal tract. Four hundred turkey eggs were incubated and distributed into four treatments with 100 experimental units each: CC and CCA (inoculation with placebo in eggshell and air chamber, respectively), ICand ICA (inoculation with 4.2 X 104 CFU/mL of Salmonella Enteritidis in eggshell and air chamber, respectively). The parameters of incubation were fertility, total hatchability and hatchability of fertile eggs, and relative chick weight to egg weight. Salmonella wasinvestigated in shell, membrane, albumen/yolk and embryo of two eggs per treatment at one, seven, 1 4, 21 and 28 days. After birth, the frequency of recovery of the pathogen in meconium of all birds was determined. The variables were analyzed by χ-square test (χ²) and Fischer test. During the whole incubation period, the agent hasremained viable in 87.5% and 1 00% of eggshell samples in treatments IC and ICA, respectively. There was migration into eggs in 33.33% and 95.45% of the samples in treatments IC and ICA, respectively. The parameters of incubation were not affected when the pathogen wasinoculated in the eggshell. It was also observed that inoculation of Salmonella Enteritidis in air chamber determined low hatchability with higher early embryonic mortality (P <0.05) than control treatment (CCA). Furthermore, air chamber control treatment determinedlow hatchability (P <0.05) with increase in late embryonic mortality (P<0.05) comparing to inoculation in eggshell. The intestinal colonization by the pathogen occurred in chicks from experimental inoculation in eggshell. It can be concluded that the assessment offertility, hatchability and ratio of chick weight by egg weight does not show presence of Salmonella Enteritidis in the hatchery. However, hatchery contamination may be determined by detection of Salmonella Enteritidis in egg components and meconium. The method of inoculationvia air chamber affected hatchability and embryo mortality. |
