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 hybridCobb 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 statisticallyprocessed by standard methods. The weight of eggs significantly influenced the lossof 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 and71.7%, respectively, with no significant difference (p>0.05). The weight of eggs didnot significantly affected the difference in embryo mortality values, although in theXL egg group a higher value of total, early and late mortality was found, comparedto other groups. The results of this study indicate lower hatchability and highermortality of embryos in eggs of extremely large weight, compared to other groups,which indicates that special attention should be given to the selection of hatchingeggs in terms of their weight.

This study aims to determine the correlation between hatching egg weight with egg weight loss and DOC weight of Bangkok male crossbreed chickens with Pelung broodstock. This research uses a unit of automatic digital hatching machines (temperature regulation and automatic turning). The research material is Bangkok rooster chicken, amounting to two tails and four Pelung broilers. The chicken is crossed, and then the eggs are collected to be hatched eggs. This study uses digital camera tools, digital scales, and calculators. The coded eggs are hatched for 21 days. The parameters measured in this study were: Hatching egg weight (grams), egg weight of day 18th hatching, egg weight loss (%) / egg shrinkage, DOC weight, the correlation value between the weight of hatching eggs with egg weight loss, the correlation value between the weight of hatching eggs with the weight of DOC. Data analysis using correlation. The results obtained were the average hatching egg weight of 45.91 ± 3.75 grams, the average of hatching eggs on the 18th day 41.13 ± 3.43 grams, egg weight loss 10.40 ± 0.56%, weight DOC 35.36 ± 3.33 grams, correlation of hatching egg weight to DOC0.98 weight, hatching egg correlation with egg weight loss -0.25. Based on the results of the study,  it can be concluded that the characteristics of Bangkok crossbreed hatching eggs with Pelung brooders are in the normal range.  The correlation of hatching egg weight with very high DOC weight and positively correlated, correlation of hatching egg weight with low egg weight loss and negatively correlated.

Four thousand two hundred hatching eggs were obtained from Bandarah chicken to evaluate the effect of chemical and natural egg disinfectants and fumigation on egg weight loss, embryonic mortality, hatchability, hatch time, chick weight and chick weight loss. Three incubation trials were done; each one contained 1400 hatched eggs and divided into fourteen treatments (100 eggs per each). First treatment (T1) was used as control without any treatment, eggs of second treatment (T2) were dipped in water and third treatment in alcohol, whereas T4, T5, T6, T7 treated egg groups were dipped in chemical disinfectant (sodium chloride, betadine, hydrogen peroxide, virkon S). Egg of T9, T10, T11, T12, T13 and T14 groups were dipped in natural disinfectants (oregano, cumin 02 and 04 % and oregano+ cumin01 and 02), respectively. The thickest eggshell (031mm) was recorded for betadine group in infertile eggs compared with those for formaldehyde fumigation and oregano+cumin 01% oregano+cumin 01% group (035mm) compared with all other treatment groups. Formaldehyde fumigation recorded the worst and highest significant percentage of embryonic mortality (1795%). Highest significant percentages for hatchability of fertile egg were recorded in egg groups with oregano 02 and 04% (9687 and 9576%), cumin 02 and 04 % (9551and 9715%) and oregano+cumin01 and 02% (9619 and 9615%), respectively.

A total of 9360 eggs was used in two series of experiments to study the effect of pre-incubation treatments on hatchability, egg weight, and chick weight. These treatments involved plastic packaging, alterations in atmospheric carbon dioxide, temperature, humidity, and time during the pre-incubation stage.Hatchability was maintained at a higher level when eggs were enclosed in plastic film during the pre-incubation period. There was also evidence that plastic packaging was more beneficial when eggs were held at adverse temperatures. Temperatures from 50 to 66° F did not appear to have a detrimental effect on hatchability when eggs were held for short storage periods. An increase in the carbon dioxide concentration in the egg storage environment depressed hatchability.Long pre-incubation holding periods tended to decrease egg weight at setting time and at the 18th day of incubation but appeared to increase chick weight. Temperatures ranging from 50 to 64° F had little effect on egg and chick weights. High humidity levels increased egg weight (when eggs were not enclosed in plastic packages) but this weight difference disappeared during incubation.

Abstract. This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.51-11.50 g), and heavy-weight (11.51-12.50 g). Based on storage period, eggs were divided into 5 groups as group 1 (0-3 days), group 2 (4-6 days), group 3 (7-9 days), group 4 (10-12 days), and group 5 (13-15 days). The influence of storage period on hatchability of fertile eggs and early, middle, and late period embryonic mortality rates was found significant (P<0.01). The effect of egg weight on fertility rate, hatchability of fertile eggs and early embryonic mortality was significant (P<0.05, P<0.01). The significant differences between storage period groups were observed in hatchability of fertile eggs. The differences between egg weight groups for fertility rate, hatchability of fertile eggs and early embryonic mortality was significantly higher in light weight group than the other egg weight groups. Results of this study concluded that a 12 day pre-incubation storage of hatching eggs of Japanese quails did not appreciably affect hatching parameters. Use of medium or heavy weight eggs for hatching may reduce early embryonic mortality rate.

AbstractThe aim of the study was to analyze eggshell temperature, embryo viability, and hatchability parameters of broiler breeders at different ages (26-30, 31-35, 36-40, 41-45, and 46-64 weeks). A total of 33,150 eggs from Ross 308 broiler breeders collected from commercial flocks were used to analyze the following: egg weight and egg weight loss during 18 days of incubation; eggshell temperature controlled on days 3, 14, and 18 of incubation; number of infertile eggs including eggs with dead embryos at early stages of development, that is, in the oviduct or after oviposition; the total percentage of embryonic mortality and the percentage of embryonic mortality at different times of incubation; unhatched, dead after hatching, and culled chicks as well as hatchability percentage from fertilized eggs. The hatchability results of Ross 308 broiler breeders were high from the beginning of reproductive season till the 40th week. However, the study failed to reveal any relationships between hatchability and the egg weight, average temperature of the shell, and egg weight loss during incubation period. The oldest hens, over 45 weeks of age, had the highest mortality of chicks and the greatest share of unhatched chicks.
