“…Research has shown that EST can be measured using the specific gravity method (Hamilton, 1982), however this method is impractical for industrial organizations and is only suitable for academic verification of nondestructive equipment (NDE) or a new method, where a the Vernier caliper can be more practically used to correct the data gathered by a NDE post-hatching or by breaking the egg. It has been reported by researchers that the thickness and porosity of the eggshell has an effect on incubation results and nondestructive methods should be used to measure the eggs and, that breeding should be based on the data gathered in order to achieve better success in breeding (Saylam and Sarıca, 1999). It was also reported by researchers that breeding for egg weight loss and eggshell quality should improve breeding results and hatchery performance (Türkyilmaz, 2005).…”

The effects of eggshell thickness (EST), shape index (SI) and egg weight (EW) on the hatch window (HW), hatching time (HT), gender of hatched turkey poults hatched were investigated. Total of 150 commercial Hybrid Converter breed turkey hatching eggs obtained from a turkey meat producing integration were used. The effects of these parameters on HW and HT and gender were analyzed via ANOVA-GLM. The hatching window was 656th – 688th hours, and the procedure concluded during the 688th hour of incubation. The incubation was divided into three partitions as early (656 – 667h), midterm (668 – 676h) and late hatches (677 – 688h), with the final 32 hours of incubation divided into 7 partitions (7P) from 1 to 7 as (656 – 664h, 665 – 668h, 669 – 672h, 673 – 676h, 677 – 680h, 681 – 684h and 685 – 688h). A significant relation between EST and gender was found as eggs with thicker EST female chicks hatched more than males (p˂0.05). There was no correlation between gender and EW and SI (p˃0.05). Meanwhile, the number of hatches for 7P, EST, EW and SI were not found to affect the hatch window of turkey eggs (p˃0.05).

Özet: Bu araştırmada, kınalı kekliklerin (Alectoris chukar) 5 aylık dönemdeki yumurta verimi farklı doğrusal olmayan modeller ile analiz edilmiştir. Kekliklerde yumurta verimini tanımlamak için Gamma, McNally, Modified Compartmental ve Adams-Bell modelleri kullanılmıştır. Modelleri karşılaştırmada Pseudo belirleme katsayısı (Pseudo-R 2), Akaike Bilgi Kriteri (AIC) ve Bayesci Bilgi Kriteri (BIC) kullanılmıştır. Gamma, McNally, Modified Compartmental ve Adams-Bell modellerinde Pseudo-R 2 değerleri sırasıyla 0.9994, 0.9995, 0.9972 ve 0.9855 olarak bulunmuştur. Bu modellere göre AIC ve BIC değerleri sırasıyla; 43.810, 49.810; 42.051, 49.051; 77.057, 87.057 ve 112.597, 122.597 olarak saptanmıştır. McNally modelinin kekliklerde yumurta verimini tanımlayan en iyi model olduğu, Adams-Bell modelinin ise en az tanımlayan model olduğu sonucu ortaya çıkmıştır. Abstract: The aim of this study was to investigate the egg yields of partridge with non-linear models in 5 mounts of lying period. Gamma, McNallay, Modified Compartmental and Adams-Bell models were used to describe egg yields of partridge. Pseudo-R 2 , Akaike Information Criteria (AIC) and Bias Information Criteria (BIC) were used to compare models. Pseudo-R 2 values were 0.9994, 0.9995, 0.9972 and 0.9855 for Gamma, McNally, Modified Compartmental and Adams-Bell, respectively. AIC and BIC values of these models were 43.810, 49.810; 42.051, 49.051; 77.057, 87.057 and 112.597, 122.597, respectively. As a result, it could be said that McNally is the best and Adams-Bell model is the least one to describe egg yields of partridges.

This study was carried out to identify the effect of the egg shape index on the hatchability, performance, and carcass yield of Japanese quails (Coturnix coturnix Japonica). Eggs were incubated in three groups, according to three different egg shape index ( , and the results showed that females were heavier than males (p<0.05; p<0.01; p<0.001, respectively).The effect of egg shape index on slaughter weight (p<0.05), left leg weight (p<0.05), liver weight (p<0.01) and liver rate (p<0.01) was significant. Females were heavier at slaughter than males in the egg shape index groups SI-I (p<0.05), SI-II (p<0.05), and SI-III (p>0.05) (female/male: 296.87/283.80, 287.95/278.00 and 283.86/278.10 g, respectively). Males presented higher carcass yield in SI-I (p>0.05), SI-II (p<0.01) and SI-III (p<0.05) (female/male: 74.40/75.92, 74.50/76.44 and 74.80/76.42%) groups than females. Egg shape index had no effect on initial egg weight (IEW), shell blunt end weight (SBW), chick weight, shank length, growth performance or carcass traits, but egg shape indexwas correlated with egg length, egg width, and hatchability of fertile eggs (p<0.05).
