AbstractSuboptimal conditions during embryonic development can affect offspring fitness. Both egg quality and incubation behavior can affect hatching success, hatching mass, and subsequent offspring performance. These effects may differ between male and female offspring. We manipulated the prebreeding body condition of Zebra Finches (Taeniopygia guttata), using diets of different protein content. To separate possible effects on egg quality of parental body condition and incubation conditions, we did a cross-fostering experiment. We analyzed embryo survival and hatching mass with respect to body condition of the egg-laying parent, body condition of the incubating foster parent, and offspring sex. Embryos were not affected by the condition of the egg-laying parent. Eggs incubated by parents in better condition suffered less embryo mortality than those incubated by parents in poorer condition, but only when overall embryo mortality was low. Hatching mass was also affected by the incubating foster parent’s body condition. And hatchlings incubated by parents in good condition were heavier than those incubated by parents in poor condition. Female hatchlings from late-laid eggs were heavier, in comparison with the size of the egg from which they hatched, than female hatchlings from earlier-laid eggs. No such effect was found for males. Therefore, male and female embryos may differ in their sensitivity to suboptimal conditions during embryonic development. These results suggest that parental body condition during incubation can affect offspring fitness.Efectos de las Condiciones de Incubación y el Sexo de las Crías sobre el Desarrollo Embrional y la Supervivencia en Taeniopygia guttata

In this study, the eggs produced in uncontrolled village conditions were compared to free-range, organic and cage-system in two seasons, in autumn and spring, in terms of external and internal quality traits. In the autumn and spring period, 110 eggs were collected from the village eggs and 50 eggs from other production systems. In order to determine the fertility in the village eggs, 60 eggs were placed in a laboratory type incubator in both seasons and fertility control was made at the 18th day. All data of egg quality traits were performed by taking the average of the two seasons. Egg shape index, shell ratio, shell thickness, shell cleanness, shell defects, albumen and yolk traits differed significantly among production systems (P < 0.05). The lowest shape index, shell thickness and shell cleanness were found in village eggs. Higher shell rates were determined from eggs in cage and organic production compared to others (P < 0.05). The yolk height and yolk index were the lowest and the yolk colors were the darkest in the white cage eggs (P < 0.05). Brown cage eggs showed the better results in the majority of their quality traits. However, they had a higher meat and blood-spot level than other systems. In addition, the presence of cockerels in the village flocks caused the fertile eggs and approximately 85% fertility was obtained. Our results showed that it has become obvious that the village hen and free range hen eggs which can be marketed in high prices compared to the commercial eggs, have no superiority in terms of the traits they are considered. Besides, as they are significantly fertile, especially in hot summer months, according to storage duration and conditions, the probability of embryo development for these eggs has turned to be of high importance for consumption.

Egg storage duration and breeder age are probably interacting to influence egg quality, hatchability, and hatchling quality. To evaluate this interaction, the impact of breeder age (31, 42, 66 weeks) and storage duration (2, 5, 12, 19 days) was investigated on broiler breeder eggs (Arbor Acres). Thick albumen diameter and pH increased, and yolk dry matter decreased between 2 and 19 days of storage. With the increase of breeder age from 31 to 66 weeks, albumen height, percentage and dry matter and shell percentage decreased and the egg weight and yolk percentage, dry matter and diameter increased. Prolonged egg storage increased the yolk pH in all breeder ages, but earlier and steeper in the oldest breeders. Prolonged egg storage resulted in a lower hatchability of set and fertile eggs due to a higher percentage of embryonic mortality. Early mortality increased earlier and steeper with prolonged egg storage in the oldest compared to younger breeders. Between 5 and 19 days of storage, yolk free body mass, liver and proventriculus + gizzard percentages decreased, as well as hatchling length and yolk efficiency (yolk absorption per initial yolk weight). The latter effects were most pronounced in the younger than in the older breeders. Therefore, eggs are preferably stored shorter than 7 d, but if long storage (≥12 days) cannot be avoided, we recommend to store eggs of older breeders when egg quality and hatchability are most important. In case hatchling quality is most important, it would be better to store eggs of younger breeders (31 weeks) for a prolonged period.

Due to consumer attitude and perception on fertile and non-fertile eggs from pervious study, this this study aimed to evaluate the interaction effect of temperature and storage duration on fertile and non-fertile eggs on egg quality characteristics. A total of 600 eggs were obtained from Lohmann brown hens, at 44 weeks. Roasters were removed from the hen that laid non- fertile eggs. Eggs collection started after 30 days of roaster withdrawal. Eggs were stored for 5, 10, 15 and 20 days respectively under room temperature (ambient) 27 – 310C and refrigeration (100C) temperature in a 2 x 5 factorial arrangement of a completely randomized design. Egg quality characteristics and sensory evaluation were assessed using standard procedures. Data were analysed using ANOVA at á0.05. The yolk weight, yolk height, yolk diameter, yolk ratio and yolk index showed significant differences (p<0.05) with storage days. Yolk colour of fertile egg stored in refrigerator at day 15 was significantly higher than other storage days. The albumen weight, albumen height, albumen length, albumen ratio and Haugh unit shows significant difference (p<0.05). Overall acceptability of fertile eggs was recorded to be the highest at day 10 of storage at room temperature. In conclusion, interaction between storage days and temperature revealed that fertile eggs can be stored in refrigerator and at room for 10 days without adverse effect on the eggs quality.     En raison de l'attitude des consommateurs et de la perception sur les œufs fertiles et non fertiles provenant d'études perméables, cette étude visait à évaluer l'effet d'interaction de la température et de la durée de stockage sur les œufs fertiles et non fertiles sur les caractéristiques de qualité des œufs. Un total de 600 oeufs ont été obtenus à partir de poules brunes Lohmann, à 44 semaines. Les torréfacteurs ont été retirés de la poule qui pondait des œufs non fertiles. La collecte des œufs a commencé après 30 jours de retrait de la rôtissoire. Les œufs ont été conservés pendant 5, 10, 15 et 20 jours respectivement sous température ambiante (ambiante) 27 - 310C et température de réfrigération (100C) dans un arrangement factorial de 2 x 5 d'une conception complètement randomisée. Les caractéristiques de qualité des œufs et l'évaluation sensorielle ont été évaluées à l'aide de procédures normalisées. Les données ont été analysées à l'aide d'ANOVA à á0,05. Le poids du jaune, la taille du jaune, le diamètre du jaune, le rapport jaune et l'indice du jaune ont montré des différences significatives (p<0.05) avec les jours de stockage. La couleur jaune des œufs fertiles conservés au réfrigérateur au jour 15 était significativement plus élevée que les autres jours d'entreposage. Le poids d'albumen, la hauteur d'albumen, la longueur d'albumen, le rapport d'albumen et l'unité de Haugh montre la différence significative (p<0,05). Dans l'ensemble, l'acceptabilité des œufs fertiles a été enregistrée comme la plus élevée au jour 10 de l'entreposage à température ambiante. En conclusion, l'interaction entre les jours d'entreposage et la température a révélé que les œufs fertiles peuvent être conservés au réfrigérateur et à la pièce pendant 10 jours sans effet négatif sur la qualité des œufs.

A total of 144 newly - laid eggs obtained from Lohmann Brown layers were distributed and stored under three storage conditions: room temperature, polythene bag/room temperature and refrigeration. Changes in Haugh unit, yolk ), index and percentage weight loss were evaluated between 0 and 14 days at intervals of two days each, Haugh unit, yolk index, and albumen have significantly (P>0.001), while percentage weight loss increased (P<0.001) with storage duration, Generally, quality on the parameters of refrigerated eggs were significantly (P<0.05) higher than those stored used in polythene bag or those stored open in the room o. Polythene-bagged eggs had the least percentage weight loss. Significant (P<0.001) storage method x storage duration interactions were obtained. Regressing the internal egg quality measurement (Y) over storage period (X) in simple linear Y = a +bx) or the exponential (Y = ab ). regression functions showed that the predictive ability measured as also the r2 - values was generally higher with the. exponential than the simple linear model. The predictive ability of each egg quality parameter was higher with the polythene - bagged eggs than  with other storage conditions. Using the simple linear prediction model, table eggs purchased randomly from retail egg shops had quality values of eggs that were about 4 - 11 days after lay prior to purchase.

This study was aimed at determining the effect of storage duration and butyric acid supplementation on egg quality of laying hens in the third phase of production. It used experimental method that employed Completely Randomized Factorial Design consisting of 2 factors; Factor A and Factor B. Factor A had 4 treatment levels of supplementation of butyric acid in diets; A0 (control treatment), A1 (0.175 g/kg diets), A2 (0.350 g/kg diets), and A3 (0.525 g/kg diets), while Factor B consisted of 3 levels of storage duration including B1 (1 week), B2 (2 weeks), and B3 (3 weeks). Each factor had 4 replications and each replication or unit consisted of 10 laying hens. The observed variables included egg weight, albumen weight, and yolk weight. The results indicated that the supplementation of butyric acid has no significant effect on the decrease of egg weight, albumen weight and yolk weight. Duration of storage significantly affected to decrease egg weight, albumen weight, and yolk weight. It can be concluded that there was no significant interaction between administration of butyric acid and duration of storage to the egg quality but duration of storage was significantly influenced the egg quality of laying hens in the third phase of production.
