“…The correlation coefficients between the 3 main internal egg components and egg weight showed that the albumen weight was strongly associated with the egg weight (r = 0.88) whereas the yolk and shell weights gave correlation coefficient values of 0.56 and 0.55, respectively. Similarly, Abanikannda and Leigh (2007) and Shi et al (2009) noticed a positive allometric relationship between albumen weight and egg weight out of the 3 components studied. However, increase in albumen weight observed in this study could not be attributed to the influence of egg weight alone because the effects of GP treatment were found to be highly significant (P = 0.002).…”

This study was conducted to investigate the potential of garlic powder (GP) in improving production efficiency, egg quality, and gut health of laying hens. A total of seventy-two 30-wk-old Dekalb white strain hens were used. The live weight of the hens ranged between 1.71 and 2.12 kg. Hens were randomly allotted into 3 dietary treatment groups in a complete randomized design experiment. The 3 dietary treatments were control (no garlic addition) and 3 and 5% GP additions to a basal diet on weight:weight ratio basis. Egg production and feed consumption were recorded daily, and hen BW and internal quality of fresh eggs were assessed weekly. Fecal samples were assessed for total bacterial load. The results from this study revealed significant (P< 0.05) increases of 0.81 mm in albumen height and 2.71 Haugh units of fresh eggs at 3% GP addition. Egg and albumen weights increased significantly (P < 0.05) by 2.06 and 1.84 g, respectively, at 5% GP over the control treatment. Egg production decreased significantly at 5% GP following a decrease in feed consumption. Similarly, log bacterial count in feces showed a dose-dependent reduction as dietary GP increased. Organoleptic evaluation of eggs from treatment birds revealed a strong garlic flavor in eggs from 5% GP group compared with the control and 3% GP groups. Results of this study suggest that dietary GP improved egg weight and albumen quality with a strong garlic flavor at high dietary levels.

“…Egg is a biological structure intended by nature for reproduction. It protects and provides complete diets for the developing embryo and serves as the principal source of food for the first few days of the chick's life (1) . It has been observed in the poultry breeding that the quails (Coturnix coturnix) were benefited as much as hens both for their meat and eggs, therefore, commercial quail breeding have become widespread (2).…”

This study was designated to evaluate some external and internal characteristics of quail eggs reared in Basrah city. Ten mature female quails were used in the present study. All birds were reared under similar environmental, managerial and hygienic conditions. To assess the egg quality parameters, a total of 100 eggs were randomly collected for 20 days. The values related to egg weight, shape index, shell weight, shell ratio , shell thickness, egg length, Egg width, Shell index and shell surface area (cm 2) are found respectively as 7.

“…The external quality focuses on the weight, size, shape and cleanliness of the egg, as well as the texture of the shell, while the internal quality refers to traits related to the yolk and albumen of the egg (Fajemilehin, 2008). Various authors suggest evaluating the relationships between some external and internal traits for a better understanding of the egg quality parameters (Khurshid et al, 2003;Abanikannda and Leigh, 2007;Alkan et al, 2015;Baykalir and Aslan, 2020). For example, the traits of weight, length and width of the egg, shape index and shell weight are highly correlated, and in turn, can be used as predictors of internal egg traits such as the weight of yolk and albumen, to facilitate their evaluation without the need to break the egg (Fajemilehin, 2008;Çiftsüren and Akkol, 2018).…”

Analysis of quality and prediction of external and internal egg traits in Mexican native turkey hens

et al. 2020

This study aimed to evaluate external and internal quality traits and determine prediction equations for some of these traits in eggs of Mexican native turkey hens. A total of 72 eggs from native turkey hens in the laying stage raised in rural municipality of Villaflores, Chiapas were measured. The external traits evaluated were: egg weight (EW), polar diameter (PD), equatorial diameter (ED), egg shape index (SI), shell weight (SW), shell percentage (SP), egg surface area (ESA) and shell weight per unit surface area (SSA). The internal traits were: albumen height (AH), yolk height (YH), albumen weight (AW), yolk weight (YW), Haugh units (HU), albumen percentage (AP), yolk percentage (YP) and yolk color (YC). The data were analyzed with descriptive statistics and Pearson correlation coefficients (r) and linear regression using the SAS program, ver. 9.4. The values obtained for the external egg quality traits showed greater variability. Pearson's correlation coefficients between external and internal traits were positive and moderately significant (P <0.05), as well as highly significant (P <0.0001), and ranged from r = 0.31 (EW vs PD) to r = 0.99 (ED vs ESA). All linear regression equations to predict EW, SW, AW and YW were found to be significant (<.0001). The best predictors of EW were PD, SI, SW and ESA (R2 = 76%). SW and YW traits can be adequately predicted using the EW and SI values together (R2 = 59% and R2 = 74%, respectively), while the AW can be predicted from the EW (R2 = 33%). Based on the results obtained, it is suggested to implement selection programs to improve the quality parameters of the native turkey hen egg in Mexico.
