Resumo
Three experiments were carried out to evaluate the effects of in ovo inoculat ion of linoleic acid, glucose,
and glutamine in chick eggs at 16th day of incubation on hatchability and performance until 10 days of age. It was used a
randomized block design with five treatments, as follows: in experiment 1, 0, 100, 200 or 300 mL of linoleic acid; in
experiment 2, 0, 100, 200 or 300 mg of glucose; and in experiment 3, 0, 10, 20 or 30 mg of glutamine. The control was
represented by the intact eggs in all experiments. In the pre hatch phase, each one of 130 eggs represented an experimental
unit, and in post hatch phase each treatment had four replicates with 15 chicks each. The inoculation of linoleic acid or
glucose increased embryo mortality and decreased hatchability and chick weight:egg weight ratio. In ovo inoculation of
linoleic acid resulted in lighter chicks. In ovo inoculation of linoleic acid, glucose, and glutamine at different concentrations
did not improve bird hatchability and performance until 10 days of age.
