“…Meanwhile, the average body weight in Common pheasant at 13 weeks of age was 1053.00±58.97 g in males and 825.00±74.25 g in females (Kokoszynski et al 2012). Compared to Rock partridge and Common pheasant, the average body weight of Japanese quail was shown to be lowest, i.e., 203.48±25.21 g in males and 228.21±26.44 g in females (Khalil et al 2006). Therefore, Rock partridge and Common pheasant can be kept for meat production (Hofbauer et al 2010;Franco & Lorenzo 2013;Wen et al 2020).…”

Rock partridge (Alectoris graeca), Common pheasant (Phasianus colchicus), and Japanese quail (Coturnix japonica) are three poultry species from the Phasianidae family birds that are kept for meat and egg production in the Republic of Turkey. This research was carried out to characterize the egg quality of Rock partridge (RP), Common pheasant (CP), and Japanese quail (JQ). The eggs parameter of egg weight (EW), shape index (SI), yolk index (YI), albumen index (AI), shell weight (SW), haugh unit (HU), yolk weight (YW), albumen weight (AW), yolk ratio (YR), albumen ratio (AR) and shell ratio (SR) were measured for data analysis. A total of 372 eggs, including 100 eggs of partridges, 200 eggs of pheasant, and 72 eggs of quail were used in this study. A Canonical Discriminant Analysis (CDA) and Hierarchical Cluster Analysis (HCA) were used in this study to characterize three different types of eggs using SPSS. 16.0 package. The results showed that nine egg parameters of AR, YI, SI, YW, AW, YR, AI, HU, and SR are identified as discriminant variables for three egg types. The results showed that the canonical correlation (R) value in this study was high, i.e., 0.98 (Function 1) and 0.79 (Function 2). The Mahalonobis distance (D2) in this study ranged from 15.28 (RP - CP) to 27.94 (CP - JQ). In conclusion, the Phasianidae poultries in this study have different egg quality traits and can be used as the species marker.

The objective of this work was to evaluate the combined effects of air temperature and air velocity on the behavior of Japanese quail (Coturnix coturnix japonica). A total of 216 Japanese quail in their initial laying phase were used. Bird behavior was categorized with an ethogram (eat, drink, stop, open wings/shiver, others). The experimental design was a randomized complete block, in a 4x4 factorial arrangement, with four air velocities (0, 1, 2, and 3 m s-1) and air temperatures (17, 23, 29, and 35°C). The behavior “stop” was greater when the birds were subjected to 17°C. At 35°C, a significant reduction (p<0.05) was observed in the behavior “eat” at 0 m s-1, compared with the other velocities. The behaviors of laying quail are similar in the morning and in the afternoon. Quail remain stopped for a longer time under cold stress conditions, at 17°C.
