Abstract
The current investigation was conducted to test the potential effects of in ovo feeding of DL-methionine (MET) on hatchability, embryonic mortality, hatching weight, blood biochemical parameters and development of heart and gastrointestinal (GIT) of breeder chick embryos. 224 Rhode Island Red fertile eggs were randomly distributed into seven experimental treatments: untreated egg (control), buffered saline (0.5% NaCl), and five solutions containing increased levels of MET (0.5, 1.0, 1.5, 2.0 and 2.5%) + 0.5% NaCl, being separated into four groups/replicates (each one with 8 eggs), totaling 32 eggs/treatment. All embryos submitted to in ovo injection with MET presented a decrease in the hatchability results and an increase in the results of intermediary embryonic mortality. Chicks hatched from eggs injected with until to 1.0% MET were heavier and presented better development of the heart and GIT, especially important organs and regions for digestion and nutrient absorption. Conclusively, the in ovo feeding using MET showed positive impacts on hatching weight and GIT development of breeder chicks. However, caused negative impacts on hatchability when used at high levels.

Abstract
The current investigation was conducted to test the potential effects of in ovo feeding of creatine monohydrate (CMH) on hatchability, embryonic mortality, hatching weight, and development of heart and gastrointestinal tract (main organs and regions) of breeder chick embryos. Rhode Island Red fertile eggs were randomly distributed into seven experimental treatments: untreated egg (control), a sterile buffered solution (0.50% NaCl), and five solutions containing increased levels of CMH (0.50, 1.00, 1.50, and 2.00%) + 0.50% NaCl, being separated in four groups/replicates (three with 15 eggs and one with 16 eggs), totaling 61 eggs/treatment and a total of 427 fertile eggs used. All-in ovo injected groups with CMH decreased the hatchability and increased the intermediary embryonic mortality. At hatching, all-in ovo injected groups with CMH also increased the hatching weight and stimulated the development of the heart and the total length of the gastrointestinal tract, especially important organs for digestion of nutrients (yolk sac, pro-ventricle and gizzard) and regions for nutrient absorption (jejunum + ileum and colon + rectum). Conclusively, the in ovo feeding using CMH showed positive impacts on hatching weight and the development of gastrointestinal tract of chicks. However, caused negative impacts on hatchability.

Abstract
The objective of this research was to evaluate techniques, incubation period, and effects of amino acids in ovo feeding. First, 240 hatching eggs were selected and distributed in a 2 × 3 factorial arrangement (two techniques and 3 d). The parameters of incubation, relative weight of gastrointestinal organs, and classification of embryonic mortality were evaluated. In the second stage, 720 hatching eggs were incubated with five treatments: control, methionine (20 and 30 mg), and lysine (20 and 30 mg). These animals were housed during 14 d. The animals were divided with five treatments, nine replicates, and groupings based on sex. Incubation parameters, performance, intestinal morphometry, and relative weight of digestive tract organs were evaluated. The results indicate that the technique using a 45° needle axis passing through the air chamber hinders hatchability. In the organ weighing, there was no difference between the evaluated factors. For intestinal morphometry, there was only a significant difference between the dose factor for the crypt villi and crypt diameter. To conclude, the technique using a 90° angle without passing through the air chamber is safer for the embryos. The inoculation of methionine (20 and 30 mg) obtained data similar to the control group.
