Resumo
This work aimed to evaluate the supplementation of different carbohydrates
and form of inoculation in low-weight eggs. Hatchery parameters, biometry of intestinal tract,
intestinal morphometry and performance of broiler chicks were evaluated. The experimental
design used was randomized blocks with five treatments and 120 replications for hatching eggs
and four treatments and ten replications for the others parameters. The treatments were designed
as follows: whole egg; inoculation on allantoidal cavity through air cell; inoculation on allantoidal
cavity with solution of maltose, or glucose or sucrose. The data were analyzed using ANOVA,
Tukey test and chi-square test. The results showed that the inoculation through air cell caused
increase of embryo mortality and decrease of hatchability. Chicks from eggs inoculated with
carbohydrates were born heavier than those not inoculated, but this extra weight was not
maintained on the first day. The supplementation of carbohydrates in ovo did not increase the
intestinal development and did not affect the initial performance of broiler chicks.
