“…With regard to embryo mortality during incubation, except for the highest early-period (0 to 6 days), medium-period (7 to 17 days) and late-period (18 to 21 days) embryo mortality rates of the heavy weight group, insignificant differences in mortality rates of weight groups totally comply with the results of earlier studies (Toplu et al, 2007;Çağlayan et al, 2009). Egg weight has no significant effect on embryo mortality rates but total (0-21 days) embryo mortality rates was increased with increasing egg weight.…”

“…With regard to hatching weights of chicks, present findings comply with the researches reporting significant impacts of egg weights on hatching weights and lighter chicks from light eggs and heavier chicks from heavy eggs (Yıldırım &Yetişir, 1998;Witt de& Schwalbach, 2004;Nazlıgül et al, 2005;Çağlayan et al, 2009). Significant effects of egg weight on body weight were lost after the second week as Yıldırım & Yetişir (1998) reported.…”

“…These discrepancies in the literature depends on the use of animals from different breeds and ages in different studies because fertility is a hereditary trait and also depends on environmental factor (Wolc et al, 2009) but it is mostly related with breeder flock ages and breed of chicks (Ulmer-Franco et al, 2010). Also fertility can highly vary even within the same breed mainly due to poor management and improper proportion of males or poor ability of males in the flock to produce viable sperms (Malago & Baitilwake, 2009) Çağlayan et al (2009 reported significantly low hatchability for light eggs but indicated insignificant differences between weight groups. Results obtained on hatchability in the present study conform to earlier findings (Elibol & Brake, 2008;Hesna Sahin et al, 2009;Ulmer-Franco et al, 2010;Alabi et al, 2012) which recommended the setting of average sized eggs for the purpose of incubation.…”

“…There are significant relationships between poultry egg weights and hatching results. Egg weight directly effects hatchability, hatching duration, embryonic mortality, hatching weights and subsequent performance of chicks (Witt de & Schwalbach, 2004;Alkan et al, 2008;Çağlayan et al, 2009;Alabi et al, 2012). Therefore, relatively heavier or lighter eggs are not preferred as hatching eggs (Abiola et al, 2008).…”

The present study was conducted to investigate the effect of hatching egg weight of broiler parent stocks on hatching results, chick performance, carcass characteristics, internal organ weights and some blood stress parameters. Eggs were divided into 3 egg weight groups (55.0 to 60.0 g (light), 60.1 to 65.0 g (medium) and 65.1 to 70.0 g (heavy)) for the experiments. After incubation, mixed-gender broiler chicks from the hatcher were placed into 27 grower pens (2x1 m) with 9 replications for 3 weight groups by using randomized block design. Each pen had 25 broiler chicks. Therefore, 225 chicks were used for each group and 675 chicks in total. The experiment was designed with nine replicates. Chi-square test, variance analysis test and Duncan multiple range test were used during statistical analysis. Hatching egg weight significantly affected egg shell thickness (p=0.042), egg weight loss on 18 th day of incubation (p<0.001), number of healthy chick (p=0.001) and deformed chicks (p=0.003), hatchability (p=0.003), hatchability yield (p=0.002), hatching weight and 7 day chick body weight (p=0.001), fresh carcass yields (p=0.002), and cooled carcass yields (p<0.001), blood triglyceride level (p=0.031), back toe relative asymmetry (p=0.032) and back toe fluctuating asymmetry (p=0.038). It was concluded in the present study that medium-weight eggs yielded better hatching results and the chicks of medium-weight eggs also yielded better outcomes with regards to other investigated parameters.

Although mostly raised as game stock and for recreational purposes, in the past decade, partridges have become one of the major alternative poultry species produced intensively. Partridges are of economic significance in many regions of the world. To ensure profitability in SUMMARYThe current research was conducted to determine the comparison of hatchability and some egg quality characteristics in spotted and unspotted partridge (Alectoris chukar) eggs. The research was carried out on 51 male and 102 female chukar partridges (Alectoris chukar) aged 50 wk, which were raised at the Research and Application Farm of the Faculty of Veterinary Medicine of Selcuk University. In total, 244 spotted and 261 unspotted eggs were used in the research. The hatching eggs were stored at 75% RH and 13°C for 14 d. Thirty spotted and 30 unspotted eggs laid on the same day were used for the evaluation of egg quality characteristics. Egg weight, chick weight, egg weight loss during the hatching period, shape index, hatchability, and some egg quality characteristics were evaluated at the end of the research. Spotted eggs exhibited a higher fertility and hatchability, as well as a lower percentage egg weight loss and embryonic mortality when compared with unspotted eggs. No significant differences were observed between spotted and unspotted eggs for egg weight, chick weight, shape index, specific gravity, albumen height, Haugh unit, yolk color green-red chromaticity (a*), albumen pH, and yolk pH. Spotted eggs had higher eggshell color a*, eggshell color blue-yellow chromaticity (b*), and eggshell strength, as well as a lower eggshell color light-dark chromaticity (l*), yolk color l*, and yolk color b* scores when compared with unspotted eggs. It was demonstrated that spots on the eggshells of chukar partridges (Alectoris chukar) improved their hatchability by affecting various quality characteristics of their eggs. It was concluded that spotted eggs are more suitable for hatching.
