The effect of the probiotics Bacillus subtilis (PB6) on the selected indicators of the table eggs quality, fat and cholesterol

The aim of this research was to monitor selected quality parameters of Japanese quails (Coturnix coturnix japonica)the loss of egg weight, changing yolk and white index, Haugh units, egg yolks color. Quail eggs were stored for 0, 1, 2, 4, 6 and 8 weeks at 4 °C. The weight of the quail eggs ranged from 11.67 to 12.27 g. The ratio of the shell range 7.60 to 8.16 % (resp. 0.89 -0.96 g), ratio of egg white from 59.33 to 62.10 % (resp. 6.31 -6.66 g) and a ratio yolk of 30.13 -32.88 % (resp. 3.68 -3.91 g). The lost of egg weight ranged from 0.47 to 2.93 % during the quail eggs storage, corresponding to a weight loss of 0.26 -0.58 g of the total weight of the eggs. The average values of the yolk index ranged from 42.67 -48.53 % and the average values of the quail egg white index ranged from 6.77 to 11.35 %. The average Haugh units were set between 56.93 and 73.72. The color of quail egg yolk was determined using the La Roche scale with the most frequent value 3. During the quail eggs storage, a statistically significant difference was found with most of the quality traits observed.

Effect of different storage times on Japanese quail egg quality characteristics

et al. 2018

“…Even more, many research studies were accomplished regarding enrichment of eggs with different micronutrients as omega-3 fatty acids, selenium and vitamin E through nutritional manipulations without deteriorating egg internal and organoleptic qualities (Hayat et al, 2014). Angelovičová et al (2013) observed the effect of dietary probiotics Bacillus subtilis (PB6) on egg weigh, egg mass weigh, egg fat content and cholesterol content in egg yolk in laying hens. Arpášová et al (2012) evaluated the influence of probiotic preparation based on lactobacillus, oregano essential oil, sumac (Rhus coriaria), propolis and pollen on egg quality parameters of laying hens.…”

Eggs and their consumption affected by the different Factors of purchase

et al. 2018

Consumers' buying behavior and preferences are affected by many factors such as the product quality, price, labeling and country of origin. The objective of this paper was to examine the opinions of the Slovak consumers about the purchase and consumption of eggs and identify their preferences at egg purchase. The input data were obtained using a questionnaire survey. The method of descriptive statistics and selected methods of measuring dependence or associations were used. The existence of statistically significant relationships was verified by the Pearson chi-square test or by the Fisher's exact test. The statistical proof of relationships was evaluated based on the significance of the test characteristic (p-value). The existence of dependence between the most important factor affecting purchasing of eggs -a price of eggs, and the age of the respondent -was confirmed. Further, the relationship between the preferred place of buying eggs and the classification criterion was also proved, i.e. whether a respondent is a breeder of the egg type of hens or not. The relationship between the preferred place of buying eggs and the gender of a respondent was confirmed as well. There was determined the dependence on the gender of a respondent in the question related to eggs consumption.

et al. 2015

Since 2008, Slovakia has implemented the National control program of Salmonella infections in laying hen flocks. This program requires the farm operators to monitor and investigate the invasive types of Salmonella (S. Enteritidis and S. Typhimurium) according to STN ISO 6579. The aim of this study was to perform a microbiological examination of dust and chicken droppings samples of laying hens in the Trenčín region for the presence of Salmonella by Horizontal method according to STN ISO 6579: 2002, to compare results with the statistics across Slovakia and selected EU countries and to evaluate the impact of official controls of salmonellosis in animals and humans. In the years 2009 - 2013 in the Trenčín region, 730 samples of dust from the conveyor belts and droppings of laying hens were taken to determine the prevalence of Salmonella in individual rearings. In these years, the incidence of positive samples was found from 0% to 29.17%. For the period from 2009 till 2013 was reported 22833 salmonellosis cases in human population of Slovakia, while in the Trenčín region it was 2636. Five-year EU-trend (2009 - 2013) showed a statistically significant decrease of salmonellosis occurence (with a mean reduction of 12% per year). The Wilcoxon signed-rank test was performed in order to provide in-depth epidemiological assessment of salmonellosis cases in Trenčin region in relation to selected characters: etiological agens, transmission mechanism, age, location as well as seasonality of infection.
