Effect of In Ovo Feeding of L-Glutamine to Chick Embryos
ABSTRACT In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine. Were used 315 fertile Rhode Island Red eggs were used (breeders with 32-weeks). The experimental design was completely randomized with the treatments constituted by two controls and five solutions containing L-glutamine levels with 45 replicates each. Data collected were subjected to polynomial regression at 5% of significance. Differences (p>0.05) were observed in hatchability and intermediary mortality, with a gradual lower of decrease in hatchability from the IOF of L-glutamine. The yolk sac was higher (p<0.05) after the IOF (control and L-glutamine) in the in ovo fed embryos at 0.5% L-glutamine. IOF of L-glutamine alone enhanced the blood pH and reduced the other serum parameters (p<0.05), which may have fuelled more embryo development, mainly vital organs how as the heart and the liver due to the larger concentration of available nutrients for the embryo. The results of this study indicate that until 0.5% L-glutamine may be supplemented in-ovo to chick embryos without negative influence on chick weight and gastrointestinal tract development, acting as serum biochemical metabolism regulator and obtaining better hatchability.
