Background: The environmental contamination with eggs increases the risk of dissemination and transmission of the parasite in dogs and paratenic hosts such as humans. We aimed to evaluate different disinfectants to compare their effect on eggs.
Methods: For its realization, 850 embryonated eggs were obtained, which were suspended in a solution of 5% formaldehyde and distilled water in Eppendorf tubes. In the tubes containing the 850 embryonated eggs, researchers was added 0.5 mL of each solution (enzymatic solution, sodium hypochlorite, iodopovidone, quaternary of ammonium, benzalkonium chloride, and super oxidation solution). After mixing, an aliquot was taken, observed under the microscope, and the number of broken eggs counted at different times to find the most effective ovicidal moment.
Results: The enzymatic disinfectant present a significant difference ( = 0.05) with 276.06 broken eggs followed by ammonium with 105.20 broken eggs. After 10 min, the ammonium solution was the one that showed a significant difference of 50.50 hatched eggs, followed by the enzymatic 26.80 and hypochlorite 25.00 treatments. After 20 min, the enzymatic solution treatment showed a significant difference with the other solutions showing an increase of 98.80 broken eggs. In the 30 and 40-min times, only the enzymatic treatment showed a significant difference of 334.10 and 381.70 of broken eggs respectively.
Conclusion: The enzymatic solution has the greatest ovicidal effect against the eggs of to present a greater number of broken eggs in a given time between 20 and 40 minutes.

This study aimed to determine the efficacy of red pine and larch pine needles powder at different doses on productive performance, egg quality, hatching parameters, total fatty acid and cholesterol levels of laying quails. A total of 126 (84 ♀ and 42 ♂) 20-week-old laying quail were randomly distributed into seven experimental diets with three replicates of six (four female and two male) birds per cage. The groups were fed a basal diet (CON group), a basal diet with red pine needle powder (RPNP group) (1.

The aim of this study was to compare the performance, egg quality and economic aspects of laying hybrids of different genotypes in free-range system. In the study, three different laying genotypes (Lohmann Brown, Lohmann Sandy and ATAK-S genotype) were used. Each group consisted of four replicates and each replicate contained 20 hens.

To solve the existing problems of low yield, uneven quality, and single form of industrially scrambled eggs, we have developed a continuous high-output steam scrambled egg device based on the principle of steam injected. By establishing calibration curves for egg, oil, and steam flow rates, determining the key parameters of the equipment, and simulating the heat transfer process between steam and egg by Computational Fluid Dynamics (CFD), we created the device and verified its production performance. The results show that the capacity of this device can reach 104.

This study examines the dietary effect of dried olive pulp (OP) on the overall performance, egg quality, health, and gut microbiota of laying hens during a 36-week trial. A total of 180 Isa Brown layers, aged 23 weeks, were assigned to 15-floor pens and divided into three feeding groups (CON, OP4, and OP6) based on the dietary level of OP. Egg quality and biochemical parameters were assessed in 39- and 59-week-old hens.

The current feeding study was designed to validate the two dietary essential amino acid profiles (EAAP) established based on linear broken-line (LBL) and quadratic broken-line (QBL) models, in a previous study, against Evonik (AMINOHen) and breeder recommendations for ISA Brown layers for peak production (PP, 20 to 44 weeks of age), and post peak production (post PP, 44 to 75 weeks of age). The EAAP based on LBL models on average had 19.5% and 26.
