<b>The aim of study was to analyze the impact of the utility type, age and rearing system of hens on egg quality traits and the enzymatic activity of egg albumen lysozyme (LA). The material consisted of 120 eggs from two genotypes of hens: Hy-Line Brown and parent stock of Ross 308. Laying-type hens were reared divided into 2 systems: intensive (litter, balanced feed) and extensive (open runs, farm fodders). The second source of material was hens age (29, 33, 41, 53 and 70 wks) of the parent stock.. Stocks were differentiated in terms of the hens age (29, 33, 41, 53 and 70 wks). Eggs quality traits and LA were evaluated. The LA of was higher in eggs from laying than from broiler breeder hens. It decreased with the hens’ age and increased with albumen mass, it was also positively correlated with albumen height and Haugh's units. The rearing system considerably modified mass of egg and albumen and the dense albumen height, but does not affect the LA.

Performance and Egg Quality of Hens from Conservation Flocks Fed a Diet Containing Maize Distillers Dried Grains with Solubles (DDGS)The objective of the study was to evaluate laying performance and quality indices of consumption and hatching eggs in hens from conservation flocks fed a diet containing maize distillers dried grains with solubles (DDGS). A total of 360 Greenleg Partridge (Z-11) and Rhode Island Red (R-11) hens, included in the genetic resources conservation programme in Poland, were investigated. The good performance obtained by layers fed the DDGS diet indicates that maize distillers dried grains with solubles can serve as a useful source of protein in the nutrition of hens from conservation flocks, partly replacing imported soybean meal. The dietary inclusion of DDGS improved laying performance while maintaining hatchability traits and the quality of consumption eggs. The DDGS diet had an effect on nutritionally important egg quality traits, i.e. increased protein content of egg albumen and increased concentration of oleic and linoleic acids in yolk lipids, with a simultaneous increase in n-6:n-3 PUFA ratio. Dietary inclusion of DDGS also increased yolk colour intensity and Haugh units while having no effect on eggshell quality.

Feed efficiency (FE) is an important measure of productivity in the layer industry; however, little is known about how FE differs between individual hens during the egg-laying cycle and the implications for egg quality parameters. Individual 25-week-old ISA Brown hens were observed for 42 days, ranked into three FE groups (n = 48 per High (HFE), Medium (MFE) and Low (LFE) FE groups and then monitored later in the laying cycle from 35–40 weeks. The groups exhibited different feed to egg conversion ratios (p < 0.001) from 35–40 weeks. Average daily feed intake and body weight were highest (p < 0.001) in the LFE group compared to the MFE and HFE groups, while albumen height, Haugh unit and amino acid concentrations of the albumen were significantly higher in the HFE groups compared to the LFE cohort (p < 0.001). This study concludes that FE status established in early lay is a stable variable until at least 40 weeks of age, and overweight, mid-laying hens that had poor FE produced inferior egg albumen quality measurements and composition. The distinct traits of the highly efficient hens and the poor feed efficient hens may provide important information to improving productivity in egg production.

Objective. Evaluate the effect of crude palm oil (CPO) on quality traits of eggs stored various days at different temperatures. Material and Methods. A total of 240 hens, 28 weeks of age were fed diets with 30 g/kg of soybean oil (SO) or CPO. After 12 weeks, sample of eggs were stored during 0, 4, 8 and 12 days at 4, 12 and 24 °C. Egg quality traits were evaluated. Results. Egg and albumen from hens in CPO diet were heavier than those in SO (p<0.05). High storage temperature reduced egg, albumen and yolk weights, Haugh units (HU), albumen and yolk heights, pH and color (p<0.05), but increased albumen and yolk widths and albumen length (p<0.05). As storage time increased, egg weight, albumen weight and height, and yolk height, pH and colour were reduced (p<0.05). However, yolk weight and width, albumen width and length increased (p<0.05). Oil x storage time interaction (p<0.05) indicated that albumen height, HU and yellowness of yolk from hens in CPO diets were better at 12 days of storage than for hens fed SO. Conclusions. Hens in CPO diet had heavier eggs and albumen than those in SO diet. Egg quality traits decreased as temperature and days of storage increased, but, eggs from hens supplemented CPO had better quality in some traits at 12 days of storage.

 It was aimed to evaluate the effect of including the waste from passion fruit pulp extraction in diets for Japanese quail in the laying phase on their production performance and egg quality. A total of 280 female quail were distributed into five treatments with eight replicates and seven birds per cage. Treatments consisted of 0, 2, 4, 6, or 8% inclusion of passion fruit waste in the diet. The experiment began with quail at 70 days of age and lasted 63 days, with performance evaluated every 21 days and egg quality in the last two days of each cycle. There was no difference between the treatments for feed intake, body weight, specific gravity, or eggshell thickness. However, a decreasing linear regression was obtained for feed intake with the inclusion of the waste, while a quadratic response was show by egg production, weight and parts of the egg. Inclusion of up to 6% passion fruit waste in diets for quail is recommended to maintain the indices in relation to control treatment. However, the best values for egg-laying rate and for the weights of egg, albumen, yolk, and shell are obtained with 2.5 to 3.5% inclusion of passion fruit waste.

Egg quality can be determined by measuring exterior quality includes egg shape, weight, while interior includes haugh unit (HU) value, yolk and egg albumen. This research aims to assess the potential of moringa leaf solution as an effort to improve the quality of quail eggs. This research was conducted from December 2017 to January 2018. The research was conducted at Badrupuyuh Farm Kp. Sukajaya RT 01/02 Ciomas Bogor Regency. The livestock that used in this research are 100 quails with age 35 day and average weight 125,93 ± 3,056 g. The feed that been used is a layered commercial and drinking water that mixed with Moringa leaf solution. The research design that been used was Completely Randomized Design (RAL) with 4 treatments and 5 replications. Treatment given in this research is R0: Drinking water without Moringa leaf, R1: 5% of moringa leaf solution, R2: 10% of moringa leaf solution, R3: 15% of moringa leaf solution. The data obtained were analyzed using Analysis of Variance (ANOVA). If it shows significant difference (P <0.05) or very significant different (P <0.01) then we will test it again with Duncan test. The variables observed in this study are egg index, weight of shell, thick of shell, yolk color and haugh unit. The application of moringa leaves solution up to 10% can increase the quail egg yolk color but has no significant effect on the egg index, the weight of the shell, the thickness of the shell and the haugh unit.Keywords: egg quality, quail, Moringa leaf solution

Abstract. This study was conducted to determine the inner quality characteristics of eggs using external egg quality characteristics. The variables were selected in order to obtain the simplest model using ridge, LASSO and elastic net regularization methods. For this purpose, measurements of the internal and external characteristics of 117 Japanese quail eggs were made. Internal quality characteristics were egg yolk weight and albumen weight; external quality characteristics were egg width, egg length, egg weight, shape index and shell weight. An ordinary least square method was applied to the data. Ridge, LASSO and elastic net regularization methods were performed to remove the multicollinearity of the data. The regression estimating equations of the internal egg quality were significant for all methods (P<0.01). The goodness of fit of the regression estimating equations for egg yolk weight was 58.34, 59.17 and 59.11 % for the ridge, LASSO and elastic net methods, respectively. For egg albumen weight the goodness of fit of the regression estimating equations was 75.60 %, 75.94 % and 75.81 % for the respective ridge, LASSO and elastic net methods. It was revealed that LASSO, including two predictors for both egg yolk weight and egg albumen weight, was the best model with regard to high predictive accuracy.

AbstractThe objective of the study was to evaluate the quality of eggs laid by native breed hens of different ages (33 and 53 weeks of age), with particular consideration of the lysozyme parameters. Eggs were collected from 6 breeds/strains of laying hens under the genetic resources conservation in Poland, i.e. Greenleg Partridge (Z-11), Yellowleg Partridge (Ż-33), Rhode Island Red (R-11), Rhode Island White (A-33), Sussex (S-66) and Leghorn (H-22). The yolks of eggs from older hens had a more favourable, intense colour, but the freshness parameters (albumen height and Haugh units) of these eggs were lower. The albumen of eggs from older hens showed greater content and higher enzymatic activity of lysozyme in both thin and thick albumen. Among the six strains of hens, lysozyme content and enzymatic activity were highest in the egg albumen of strains Ż-33, Z-11 and R-11, and lowest in that of strain H-22. The analysed eggs showed statistically significant correlations between some interior egg quality traits (albumen weight, albumen height, Haugh units, yolk colour) and the discussed enzyme parameters. These traits are influenced by genotype and age of the hens.
