“…Once the homogenization management of incubated eggs is adopted, it is naturally expected that the egg weight will not show significant changes, but the supplementation of the oils could affect the weight of the chick at birth, as already recorded in a previous study conducted by Damasceno et al (2017), this fact not observed in the present study (Table 2).…”

The objective of this study was to evaluate the effects of inoculation in egg with sources of conjugated linoleic acid (CLA) and lauric acid (LA) on hatchability, zootechnical performance and carcass characteristics of quails from one to 35 days of age. On the 7 th day of incubation, the eggs were inoculated with 0.05 mL of the supplement according to the treatments, CLA and LA. After birth, the birds were housed in cages until 35 days. A completely randomized design was used, with six treatments and six replicates of 10 birds per cage. The inoculations in eggs with CLA and LA did not interfere in the performance and carcass characteristics of quails at 21 and 35 days of age. However, may be associated with a decrease in egg hatchability. The highest absolute weight of the gizzard was observed at 35 days, from birds inoculated in egg with CLA 240 mg and LA 60 mg in the incubation phase, in comparison to the other treatments. In conclusion, the reduction in hatchability makes it impossible to recommend the use of conjugated linoleic acid and lauric acid -in ovo.

“…Our results pointed that the use of IOF increased the hatchability (IOF Control and at 0.5% L-glutamine) and the development of the gastrointestinal tract, attributing these results to the increase in available nutrients to the chicks during the embryo development. Based on positive preliminary studies using amino acids and proteins (Pedroso et al, 2006;Damasceno et al, 2017), the first objective of IOF is to increase the concentration of available nutrients and improve the embryo development of chicks (Foye et al, 2007). However, Damasceno et al (2017) reported that high levels of substances using to IOF may cause a gradual reduction in hatchability, and a subsequent increase in embryo mortality, especially the intermediary embryo mortality (shortly after inoculation).…”

“…The use of substances to IOF such as amino acids and extracted/isolated proteins may be beneficial to the embryo due to its function to growth metabolism. Physiologically, these substances are not considered the main energy source to muscle contraction, but act as an important energy source for the skeletal muscle during metabolic stress (Nelson and Cox, 2014;Damasceno et al, 2017), providing nutritional support to the embryo and assisting in the final stage of embryo development.…”

Effect of in ovo feeding of L-glutamine + ISP to chick embryos

et al. 2019

In ovo feeding (IOF) is the biotechnology that injects nutrients into the amnion of the avian embryo may cause an increase in hatchability and gastrointestinal development, and affecting the serum metabolism. This hypothesis was evaluated using 5 IOF solutions containing L-glutamine and L-glutamine + ISP (Isolated Soy Protein). 300 fertile eggs Rhode Island Red (breeders with 43-weeks) were distributed in a completely randomized experimental design with the treatments constituted by two controls (intact egg and IOF control with saline solution) and three solutions containing L-glutamine and L-glutamine + ISP, with 60 replicates (eggs) each. Data collected were subjected to the Tukey test at 5% of significance. There was a significantly lower (p<0.01) in hatchability from the IOF of L-glutamine + ISP, and a consequent increase in the intermediary embryo mortality. The yolk sac was higher (p<0.01) in chicks subjected to solutions containing 0.5% L-glutamine and 0.5% L-glutamine + 1.0% ISP, whereas all in ovo embryos presented great (p<0.05) development of heart and pancreas than intact eggs. In ovo fed embryos at 0.5% L-glutamine and 0.5% Lglutamine + 1.0% ISP presented great developed of gastrointestinal tract than intact eggs. In conclusion, the results of this study indicated that 0.5% L-glutamine may be used to IOF in chick embryos without a negative influence on chick weight and gastrointestinal tract development, acting as a metabolism regulator and obtaining better hatchability.

“…Lauric acid, in turn, is abundantly found in coconut oil and has immunological activities, which are described in several studies as antiviral, antibacterial, and anti-protozoan properties (Donaldson, Madziva, & Erlwanger 2016). The nutritional management of a diet can act as a modulator to produce specific responses, naturally strengthen immunity, and thus improve the performance of birds in the face of health challenges present in the breeding system (Damasceno et al, 2017). According to Pinto et al (2014), the current interests revolve around n-3 fatty acids that can act by inhibiting the synthesis of inflammatory mediators derived from achydodon acid.…”

The objective of this study is to evaluate the effects of in-egg inoculation with sources of conjugated linoleic acid (CLA) and lauric acid (AL), going by the weight of lymphoid organs and the biochemical profile of the blood of cut quails, from one to 35 days of age. We used 360 quails distributed in a completely randomized design, in six treatments and six replicates of 10 birds per plot. Corn oil (OM) was used to dilute the CLA and AL. The experimental treatments were: healthy eggs (control); eggs inoculated with OM thinner; eggs inoculated with CLA 120 mg / 50 mL OM; eggs inoculated with CLA 240 mg / 50 mL OM; eggs inoculated with AL 60 mg / 50 mL OM and eggs inoculated with AL 90 mg / 50 mL OM. The results were analyzed through Program R at the level of 5% significance. To verify the normal distribution of errors, the Shapiro-Wilk normality test was applied. At 21 days, an effect of p < 0.05 was observed for the total blood cholesterol content, inoculations with CLA reduced, even as AL increased, regardless of the level. At 35 days, it was found (p < 0.05) that the levels of total cholesterol and AST in the blood decreased with inoculations of CLA and AL at the lower levels, compared to those that did not receive the inoculations. The CLA and AL levels supplemented via egg inoculations did not interfere with the weight of the lymphoid organs (thymus, Fabricius bursa) of the birds, at both ages. Supplementation in eggs of cut quails with CLA 240 mg reduced the total blood cholesterol content compared to CLA 120 mg, at 21 days of age. At 35 days of age, higher concentrations of CLA and AL increased the total cholesterol and AST in the blood of birds and AL had a greater effect on the increase than CLA.
