“…The highest fertility ratio (90.9%) was recorded for the eggs whose weight and width were 10.425 g or lighter and 24.565 mm or narrower in other colored quail except for yellow quails in the current data. However, the present highest ratio was slightly lower in comparison with the corresponding ratios informed by Uckardes et al (2014). The main difference for fertility in literature may be attributed to usage of different factors (cage type, stocking density, mating ratio, and rearing system etc.…”

“…Studying the influence of cage type and mating ratio on fertility of the eggs of Japanese quail, Narinc et al (2013) noticed that the higher fertility ratios of 87.43 and 84.26% were estimated for the quails housed in individual cages and colony cages, respectively, compared with the overall fertility ratio in the study. The current general fertility ratio was lower than the ratio (82%) given as a result of selection studies in Uckardes et al (2014). However, the authors found the highest fertility ratios for control line (96.4%) and selection line (90.6%) at a stocking density of 240 cm 2 /quail in autumn in the CHAID analysis.…”

“…In the determination of optimal conditions for quail production, powerful statistical approaches help breeders to perfectly establish some decisive factors and egg traits on fertility and hatchability. Herewith, as of lately, few studies on data mining algorithms have been conducted for deciding factors and egg characteristics affecting hatchability and fertility in poultry production (Karabag et al, 2010;Kucukonder et al, 2014;Uckardes et al, 2014).…”

“…With the development of computer technology at the present time, statistical analysis of the algorithm is feasible in SAS (Statistical Analysis System), SPSS (Statistical Package for Social Sciences) (Ali et al, 2015), and STATISTICA (Camdeviren et al, 2007;Nisbet et In the classification problems, usage of various datamining algorithms for animal science has recently been recorded for beef cattle Kucukonder et al, 2015), dairy cattle (Grzesiak et al, 2010;Grzesiak et al, 2011;Zaborski et al, 2014;Bayram et al, 2015), and fisheries science (Topal et al, 2010).

Among the researchers, Uckardes et al (2014) preferred CHAID (chi-square automatic interaction detector) data-mining algorithm to identify the effects of genotype, season, and cage stocking on fertility for Japanese quail, while Kucukonder et al (2014) described the influence of season, selection, and cage stocking on fertility of Japanese quail with several classification algorithms.…”

Usability of CART algorithm for determining egg quality characteristics influencing fertility in the eggs of Japanese quail

-The objective of this study was to determine the effects of egg quality characteristics (egg weight, egg width, egg height, and shape index) on fertility of eggs of Japanese quail with different colored feathers (yellow, white, grizzled, and normal), which are of economic importance for poultry production. For this purpose, 383 eggs of Japanese quail with various feather colors were used. In the study, usability of classification and regression tree (CART) data-mining algorithm as a classification tree method is necessary for poultry breeders to define proper cut-off values of egg quality characteristics that ensure Japanese quail eggs at good quality in fertility. Fertility as the dependent variable in the study was examined as a binary trait (fertile and infertile) and all the egg quality traits accepted as explanatory variables were continuous variables. Feather color was also included as a nominal categorical explanatory variable. The classification tree results showed that the highest fertility ratio of 90.9% was obtained from the eggs of Japanese quail of white, grizzled, and normal feather colors with 10.425 g ≥ egg weight, 24.565 mm ≥ egg width, or the fertility ratio of 88.2% of the eggs was observed with 10.425 g ≤ egg weight and 25.605 mm ≥ egg width. Consequently, usability of the tree-based CART algorithm is important in practice for properly establishing fertilized eggs, depending on feather color types of Japanese quail.
