<b>Effect of maltose, sucrose and glucose supplementation in embryonated low-weight eggs</b> - DOI: 10.4025/actascianimsci.v32i1.5910

Abstract

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.
