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.

The aim of this study, the effect of addition to salep at different concentrations (2.5, 5, 7.5 and 10%) into sucuk on physicochemical, textural and sensorial properties were investigated at d fermentation and storage periods (5., 10., 20. ve 30. days). The results indicated that TBARS values gradually increased during fermentation and storage periods in all treatment groups. However, addition of 10% salep decreased TBARS values compared to control group at the end of fermentation and storage period. pH values of sucuks were decreased with addition of salep. Higher L* values were observed in sucuk with 10% salep at the end of the fermentation and storage period. Increasing levels of salep in sucuk formulation caused an increase in hardness and ash values, a decrease in moisture values in sucuk. The results of this study indicated that salep may be used in sucuk manufacture by the meat industry to improve shelf-life and quality parameters of the product.

The influence of breed and storage period of hatching eggs on the duration and results of incubation and the development of quail was studied. It has been noted that in breeding quail farms, the collection period for hatching eggs can be as long as 2-3 weeks. Storage time has a negative effect on incubation time, embryo development, egg hatchability and hatchability of young chicks, which consequently reduces the economic efficiency of the poultry farm. The study was carried out on the eggs of the Pharaoh and Texas White quail breeds. It was found that storage of quail eggs for more than 7 days reduces the hatchability of eggs by 8.3-38.2% and the hatchability of young quail eggs by 15.7-41.4%. Reduced fertilization of eggs correlated with the loss of egg weight during storage (r = 0.974-0.995, p < 0.05). Extending the shelf life of quail eggs to 14-21 days increased the average incubation hour of the Pharaoh breed by 6.3-12.1 hours, and the Texas white breed by 2.5-9.7 hours, had a significant effect during the embryogenesis period on the live weight of day-old quails of both breeds, utilization of yolk sac nutrients and development of the heart, liver and gizzard (η2 = 0.541-0.902, p <0.05-0.01). Hatchery eggs of the meat quail breeds Pharaoh and Texan White should be stored for no more than 7 days before incubation. The results of this study can be used in breeding, industrial and farm quail farms for planning sampling times, the number of eggs laid for incubation and places for planting day-old chicks, the number of future layers, the amount of feed needed; in the educational process of agrarian educational institutions.

Both pre- and post-rigor beef semimembranosus muscles were ground with salt (0, 2 and 4%) and then subdivided into two treatment groups (freezing and freeze drying) and evaluated during storage of 0, 5, 10 and 15 wk for chemical and sensory traits. Rehydration ratios of pre-rigor freeze-dried beef (salted or unsalted) were not significantly changed during a 15-wk storage period at 25°C. With the addition of 2 and 4% salt, pre-rigor freeze-dried beef was less susceptible (P&lt;0.05) to lipid oxidation (lower TBA values) than post-rigor, freeze-dried beef. Pre-rigor, freeze-dried beef was superior to post-rigor, freeze-dried meat in all sensory traits studied. Differences in TBA values were not significant between pre-rigor and post-rigor, frozen beef treatments at any salt level (0, 2 and 4%). Pre-rigor, frozen beef samples were superior (P&lt;0.05) to conventional post-rigor, frozen meat in panel tenderness and acceptability scores. The TBA values of pre- and post-rigor beef (frozen or freeze dried), in general, increased with increased salt level (0, 2 and 4%). Freeze-dried beef samples (pre- or post-rigor) were less (P&lt;0.05) tender, cohesive, acceptable and more rancid and/or off-flavor than frozen meat (pre- or post-rigor).

Abstract The aim of this study was to determine the effect of egg water loss during storage and incubation on hatch rates in heavy-type broad-breasted white BUT Big 6 turkeys. Turkey hens started laying eggs at 30 weeks of age. In weeks 2, 8, 16 and 21 of the laying season, 1512 eggs were selected randomly and divided into 4 groups of 378 eggs each. The groups of eggs were stored for 7, 10, 13 or 17 days before incubation. At the beginning and end of the storage period and on days 9, 15, 21 and 24 of incubation, eggs were weighed to determine the percent water loss relative to the egg’s weight. Four incubation cycles of 378 eggs each were performed for each storage period. A total of 16 incubation cycles were carried out (4 weeks of the laying season × 4 egg storage periods) and the following parameters were determined (%): egg fertilization, dead embryos, unhatched eggs and hatchability results from fertilized eggs. The percentages of dead embryos and unhatched poults with physical defects and abnormal position were determined in hatchery waste from each incubation cycle. Egg water loss varied throughout storage and reached 0.57% of total egg weight after 7 days, 0.79% after 10 days, 0.87% after 13 days and 1.28% after 17 days (P≤0.05). After 7 days of storage, egg water loss during a 15-day and 21-day incubation period reached 5.76% and 8.72%, and lower values were noted after 17 days of storage (P≤0.05). Egg water loss of 1.28% during storage resulted in a high rate of early embryonic mortality (14.81%) and a low hatch rate (72.12%) (P≤0.05). High water loss in stored eggs contributed to a higher percentage of congested embryos. During storage, egg water loss reached 0.72% in week 2 of the laying season, 0.78% in week 8 and ≥1% in weeks 16 and 21 of the laying season (P≤0.05). Egg water loss during a 21-day incubation period was similar in weeks 2, 8 and 16 of the laying season, and lower in week 21 (P≤0.05). The hatchability of turkey eggs was lowest in weeks 16 and 21 of the laying season (P≤0.05). Low water loss during incubation contributed to a high rate of late embryonic mortality (13.2%). High water loss during egg storage is accompanied by lower water loss during incubation. Water loss should be monitored after storage and on days 15 and 21 of incubation to evaluate water metabolism in hatching eggs.

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.

Four hundred fertile eggs of broiler breeder Ross strain were incubated in commercial Hatchery. Eggs were injected into amniotic fluid on 18th day of incubation after divided into four treatment groups (100 eggs per treatment) with two replicates. First treatment was injected 100 µl of PBS, second treatment was injected with100 µl of inactivated ND vaccine, the third treatment was injected with 100 µl of inactivated ND vaccine and 50 µl vitamin E (oily form) and finally the fourth treatment was injected with 100 µl of inactivated ND vaccine and 50 µl Cod liver oil. All injected eggs were carried back into hatchery for complete hatching process. Hatched chicks were transported to the farm of the Veterinary Medicine College/University of Baghdad for 42 days from 6/10/2011 to 16/11/2011. The hatched chicks from the previously treated groups were distributed into four treatments with two replicates for up to the experimental end. Results of treated groups showed significant (P ≤ 0.05) increase in body weight, weight gain, as well as significant reduce in feed intake and improvement in feed conversion ratio, also, antibody titers against Newcastle disease virus of treated groups showed significant (P ≤ 0.05) increase progressively with age until the end of the experiment compared with broiler chicks of control.

And Storage

The effect of testing temperature and storage period on the polarization fatigue properties of poly (vinylidene fluoride-trifluoroethylene) (P(VDF–TrFE)) ultrathin film devices were investigated. The experimental results show that, even after stored in air for 150 days, the relative remanent polarization (Pr/Pr(0)) of P(VDF–TrFE) of ultrathin films can keep at a relatively high level of 0.80 at 25 °C and 0.70 at 60 °C. To account for this result, a hydrogen fluoride (HF) formation inhibition mechanism was proposed, which correlated the testing temperature and the storage period with the microstructure of P(VDF–TrFE) molecular chain. Moreover, a theoretical model was constructed to describe the polarization fatigue evolution of P(VDF–TrFE) samples.
