This study was conducted to determine the influence of eggshell thickness, albumen height, yolk height and haugh unit on hatching results. A total of 746 eggs, which were obtained and evaluated for egg quality parameters from 100 brown pure line hens of 42 weeks of age, were used. Eggs were collected from each hen for 12 days and individual incubation was carried out. Eggs were grouped based on quality parameters and evaluated accordingly. The findings suggested that hatchability, hatchability of fertile eggs, early, mid and late embryonic mortality did not differ in terms of haugh unit, albumen height, eggshell thickness and yolk height groups. However, early embryonic mortality was found different between the yolk height groups. No relationship was determined among albumen height, haugh unit, eggshell thickness and hatching results. There was no relation between yolk height and hatchability of fertile eggs, hatchability, mid and late embryonic mortalities but was a positive correlation with early embryonic mortality. The results of the present study demonstrate that egg quality parameters studied here had no influence on hatching results except that early embryonic mortality increased with the yolk height.

In order to confirm the dietary calcium (Ca) requirement to keep a balance of the production performance and the albumen transparency, the study examined the effects of different dietary Ca levels on the production performance, egg quality, and albumen transparency of laying pigeons. 1080 pigeon pairs were randomly allocated into six treatment groups, each consisting of six replicates of 30 pigeon pairs per treatment. Ca levels of 0.60, 0.90, 1.20, 1.80, 2.40, and 3.00% were fed. The results showed that the laying rate, average egg weight, and feed to egg ratio were significantly influenced by Ca levels (p < 0.05). Albumen percentage, albumen height, Haugh unit, and eggshell thickness at 8 w and 16 w were significantly influenced by Ca levels (p < 0.05). The L*, a*, b*, and c* values of cooked albumen at 8 w and 16 w were all significantly influenced by Ca levels (p < 0.05). After 16 w of feeding different Ca levels, the percentage of transparent eggs had an early increasing and later decreasing trend. In conclusion, taking the transparency of pigeon eggs as an assessment index and considering production performance secondly, the optimal level of dietary Ca for laying White King pigeons is 0.90%.

ABSTRACT Eggs are one of nearly perfect protein foods, offering nutrients of great biological value. However, during storage, egg albumen and yolk components may alter and deteriorate egg quality. Therefore, the aim of this work was to assess egg quality during 9-week storage. Parameters such as Haugh unit, weight loss, egg width and length, specific gravity, yolk and albumen dimensions and their pH were evaluated weekly. A total of 270 eggs (n=5) collected from two different hen strains were evaluated under room (20 to 35 °C in summer; 11.2 to 29.7 °C in autumn) and refrigerated (0 to 5 °C in summer; -3.1 to 6.5 °C in autumn) temperatures. For storage time, an unfolding analysis was accomplished by regression analysis using orthogonal polynomials. As a second approach, principal component analysis (PCA) was performed in order to assess correlations among quality parameters on storage conditions and laying hen strains. By the end of the 9-week storage period, eggs kept under refrigeration presented similar quality parameters to eggs stored at room temperature for only 3 weeks. In contrast, eggs kept at room temperature presented faster degradation from week 1 to 5. No differences on egg quality parameters were noticed between white and brown shells eggs. PCA suggests that better egg quality (first week) was associated mainly with higher egg weight and its specific gravity, Haugh unit and albumen height. Eggs stored at room temperature should be consumed in 2 weeks or refrigerated until 8 weeks, preserving internal quality from farm to retail.

An experiment was conducted to determine the effects of feeding diets containing 0, 5, 10, and 15% ground raw rapeseed to three replicates of 14 laying hens each. Isocaloric isonitrogenous diets were fed for a 28-day experimental period and performance and egg quality parameters were measured. Egg production was depressed at the two higher levels of rapeseed inclusion but was not affected at the 5% level of inclusion. Haugh unit, albumen height, and shell deformation were not affected significantly (P > 0.05) but egg weight decreased progressively as rapeseed inclusion increased. Feed consumption was significantly depressed (P < 0.05) at the 15% level of rapeseed and slightly reduced at the other levels.

Summary The purpose of this study is to examine the effects of the storage period on the quality characteristics of Bovans Brown table eggs. Eggs from 47-week-old hens were sampled on the day of laying and stored in a refrigerator (4°C) for periods of 7, 14, 21, and 28 days. Measurements were performed for each storage period relative to the most important quality parameters of eggs. The following egg parameters were evaluated: weight, weight loss, shell breaking force, albumen height, Haugh units and yolk color. The results obtained show that the albumen height and Haugh unit (HU) were affected by the storage period and are of immense importance. The following parameters were found to be significantly influenced by different storage periods: weight loss (P<0.05), albumen height (P<0.05) and Haugh unit (P<0.01). Rapid reductions in the albumen height were recorded during 7, 14, 21 and 28 days of storage (ranging from 6.90 mm to 6.07mm). Moreover, the Haugh unit values also decreased during storage from 81.27 to 74.89 at 4°C. The present results suggest that the albumen height and the Haugh unit are the most important parameters of egg quality, obtained from commercial layers raised in battery cages, affected by a storage period of 4 weeks.

The study was conducted to investigate the effect of dietary diatomaceous earth (DE) on egg quality traits in deep litter hens. A total of 280 Lohmann Brown pullets were at 20 weeks of age divided into 4 groups. Three groups were fed on one of the three experimental diets supplemented with 2%, 3% or 4% DE, while the fourth group was fed on a control diet without DE supplementation. Each group had seven replicates of 10 birds. One egg was collected randomly per replicate (for a total of 7 eggs per group), weighed and determined for: yolk weight, albumen weight, eggshell weight, eggshell thickness, specific gravity, albumen height, yolk height, yolk colour and Haugh unit. Findings showed that DE supplementation resulted into significant (p<0.05) increase in eggshell weight and yolk height. Dietary supplementation with DE in the current study was, however, not effective on other egg quality parameters such as on eggshell weight percentage, egg specific gravity, yolk colour and Haugh unit. However, results of the study also showed that DE supplementation improved significantly (p<0.05) egg quality especially by improving viscosity as flocks grew older as compared to younger flocks. Further research should focus on the effect of dietary DE on eggshell and bone strength of layer birds. Research should also explore the interactions among the minerals found in DE (e.g. calcium, phosphorus and magnesium) and how these interactions affect egg quality in laying hens.

The study was carried out to identify some production traits of the pure Barred Rock 1 (BR1) line and rapid × slow feathering line crosses derived from the BR1 pure line, in addition to F1 crosses of all these dam lines with Rhode Island Red 1 sire line. The BR1 line previously used a brown layer dam line for barred/non-barred day-old chick auto-sexing and synthetic slow and rapid wing feathering lines. Parent lines showed significant differences in sexual maturity and egg production (P < 0.01) and early embryonic mortality (P < 0.05). However, there was no significant difference in weight at sexual maturity, average egg weight, hatchability of fertile eggs, hatchability of total eggs set, and middle and late embryonic mortalities. A significant difference was found among F1 crosses with respect to weight at sexual maturity (P < 0.05), but no significant difference (P > 0.05) could be determined for age at sexual maturity and egg production. Overall, rapid feathering hens had better production traits than slow feathering hens. The dual crossbred parent lines exhibited almost the same level of egg production traits compared with the pure line.

Abstract: The objective of this work was to evaluate the influence of the inclusion of soybean (Glycine max) gum in the diet of laying hens on egg production, egg external and internal quality, and economic viability, as well as of temperature and storage time on the oxidative stability of eggs. One hundred and eighty 40-week-old Lohmann-LSL layers were fed 0, 1, 2, 3, 4, and 5% soybean gum in the diet. In the economic analysis, the average productive performance of the layers and the cost of feed were considered. In order to evaluate oxidative stability, eggs were stored at room temperature (~30oC) or refrigerated (5oC) for 0, 7, and 21 days. The inclusion of soybean gum in the diet increased feed intake and also egg production, average weight, and mass. Soybean gum improved external and internal egg quality parameters, but reduced the Haugh unit. Oxidative stability was higher in eggs from hens fed 4% gum, at 5oC, for 21 days; however, the largest economic return was with 1% gum. The inclusion of soybean gum promotes improvements in the production, external and internal quality, and oxidative stability of eggs from commercial laying hens.

Asam kandis  (Garcinia  cowa  Roxb)  fruit has been reported to contain phytochemicals such as xanthon, hydroxy cytric acid and flavonoids that have various activities such as antimicrobial and antioxidant. This study was aimed  to investigate the effect of asam kandis extract addition in drinking water on the quality of quail eggs. Ninety nine laying quails of 59  days of age were divided into 3 treatments and 3 replications with 11 laying quails in each replication. Completely Randomized Design was used and the treatments were: T1= control  (drinking water without asam  kandis extract), T2= drinking water with asam kandis extract at pH 4, T3= drinking water with asam kandis extract at pH 3. The parameters observed were egg weight, egg shape index, yolk color, yolk percentage, albumen percentage, eggshell percentage,  shell thickness, and haugh unit score. The data obtained were analyzed by Analysis of Variance (ANOVA) and significant  differences among treatments means were tested  by Duncans multiple test. The  the addition of asam kandis extract did not affect (P0.05) on egg weight, egg shape index, yolk color, yolk percentage, albumen percentage, eggshell percentage, and haugh unit score. The addition of asam kandis extract in drinking water at pH 3 significantly (P0.05) increased eggshell thickness compare to that of other treatments. The conclusion was the addition of asam kandis extract in drinking water at pH 3 increased eggshell thickness without decreasing egg quality.

The external and internal qualities of 120 eggs (60:60) from Isa Brown (IB) and Bovan Nera (BN) layer breeders were evaluated at 15th and 30th week of their production. The genotypes differed significantly (P<0.09) m external egg quality traits except egg weight and egg length. IB recorded higher values in egg width, eggshell weight, eggshell thickness, shape index and shell ratio than BN, while the reverse trend was for egg length. This implies that IB genotype produced eggs with thicker shells than BN, which invariably will lead to a reduction in the rate of cracks and leakages both on the farm and in the hatchery thereby enhancing better hatchability. The age effect was significant (P<0.05) for all the external egg quality traits. The analysis showed that eggs produced at 30th week were better in terms of external quality traits with the exception of egg shape index. There was positive and significant (P <0.05) interaction effect between genotype and age on eggshell width and shell ratio but not for other traits. As regards internal egg quality traits, the genotypes differed significantly (P<0.05) in all the traits except yolk width, yolk height and albumen weight. IB recorded higher (P<0.05) values in yolk weight, albumen width and yolk ratio than BN, while the latter recorded higher values in albumen height, albumen ratio and haugh unit (HU) than the former The effect of age on internal traits was positive and significant (P<0.05) with the exception f yolk width, albumen width, yolk ratio and albumen ratio. The result showed that the 30th week analyses recorded higher (P<0.05) values in these traits than 15th week. This implies that the quality of breeding eggs improves with the advancing age of the birds. Breed x age interactions were significant for yolk weight and albumen width but not found for other traits. IB genotype was considered the best for external egg quality traits and produced thicker eggshell. However, BN genotype produced superior egg quality than lB having recorded higher values (P< 0.05) in HU, which is a determinant of egg quality
