“…This finding is consistent with the data reported by Abudabos et al (2017) for the incubation of eggs of autochthonous free-range chickens, and those by Duman and (2017) for the egg incubation of meattype hybrid. On the contrary, Rosa et al (2002) found a significantly higher total mortality in the group of large eggs of an average weight of 73.2 g (9.6%), compared to eggs of an average weight of 60.0 g (7.0%) and 65.1 g (6 , 7%), which is consistent with the results obtained by Iqbal et al (2016) Kopecký (2015) found the highest total mortality in the group of eggs weighing 70-75 g (16.7%), and the lowest in the group weighing 55-60 g (9.7%).…”

Abstract:The aim of study was to examine the values of the incubation parameters (weight loss, fertilization, hatchability of placed and fertilized eggs, total, early, middle and late embryonic mortality) of eggs of different weights in brolier hybrid Cobb 500. In total, 600 eggs were divided into four equal groups (n = 150 each) according to their weight: 57.5-62.5 g (S); 62.6-67.5 g (M); 67.6-72.5 g (L) and 72.6-77.50 g (XL). Values of incubation parameters were determined and statistically processed by standard methods. The weight of eggs significantly influenced the loss of egg weight during incubation (p<0.05), with this loss being higher in smaller eggs (group S 11.10% and group M 11.40%) compared to larger eggs (group L 10.42% and group XL 10.31%). Hatchability of all eggs in groups S, M, L and XL was 76.0; 75.3; 78.7 and 66.0%, respectively, and for fertilized it was 82.0; 81.3; 82.5 and 71.7%, respectively, with no significant difference (p>0.05). The weight of eggs did not significantly affected the difference in embryo mortality values, although in the XL egg group a higher value of total, early and late mortality was found, compared to other groups. The results of this study indicate lower hatchability and higher mortality of embryos in eggs of extremely large weight, compared to other groups, which indicates that special attention should be given to the selection of hatching eggs in terms of their weight.

Cilj rada bio je da se ispitaju vrijednosti parametara inkubacije(gubitak mase, oplođenost, valivost uloženih i oplođenih jaja, te ukupan, rani,srednji i kasni embrionalni mortalitet) rasplodnih jaja različite mase teškog linijskoghibrida Cobb 500. Ukupno je ispitano 600 jaja podijeljenih u četiri jednake grupe(n=150) prema njihovoj masi: 57,5 – 62,5 (S); 62,6 – 67,5 (M); 67,6 – 72,5 (L) i 72,6 –77,50 g (XL), a vrijednosti parametara inkubacije određene su i statistički obrađenestandardnim metodama. Masa jaja uticala je statistički značajno na gubitak masejaja tokom inkubacije (p<0,05), pri čemu je taj gubitak bio veći kod jaja manje (grupaS 11,10% i grupa M 11,40%) u odnosu na jaja veće mase (grupa L 10,42% i grupaXL 10,31%). Valivost uloženih jaja u grupama S, M, L i XL iznosila je 76,0; 75,3;78,7 i 66,0%, redom, a oplođenih 82,0; 81,3; 82,5 i 71,7%, redom, pri čemu nijeustanovljena statistički značajna razlika (p>0,05). Masa jaja nije statistički značajnouticala na razliku u vrijednostima mortaliteta embriona, iako je kod jaja grupe XLustanovljena viša vrijednost ukupnog, ranog i kasnog mortaliteta u odnosu na ostalegrupe jaja. Rezultati ovog istraživanja ukazuju na niže vrijednosti valivosti i višimortalitet embriona u inkubaciji jaja izrazito velike mase u odnosu na ostale grupe,zbog čega izboru jaja za nasad treba posvetiti posebnu pažnju i u pogledu mase.

The aim of this study was to estimate the genetic parameters and inbreeding effect on the fertility, embryo mortality and hatchability traits in the Zatorska goose covered by the animal genetic resources conservation program. The material for this study contains information about results of hatching of 18 863 eggs from 721 dams and 168 sires, laid between 1998-2015. Genetic parameters were estimated based on the threshold animal model by the use of Restricted Maximum Likelihood and Gibbs sampling. The percentage of fertilized eggs ranged yearly between 37-80%. The percentage of embryo mortality was very low, ranging between 4.63-23.73%. The percentage of the hatched goslings from the total number of analyzed eggs was on average 33.18%, and 53.72% from fertilized eggs. On average based on both methods, the heritability estimates of the fertility, embryo mortality and hatchability reached 0.36, 0.07, 0.24 for males and 0.44, 0.11, 0.32 for females. The genetic trend had increasing tendency for fertility and hatchability and was stable for embryo mortality for both sexes. The obtained result shows that the Zatorska goose can be still maintained in the reserves of the local gene pool according to current rules and use in the local market as a breed with good reproductive potential.
