Summary: The study demonstrated that supplementation of nanoselenium (NS) or selenium yeast (SY) can enhance the performance and antioxidant capacity of hens, as well as improve selenium deposition in eggs, liver, and kidney. Selenium yeast supplementation also increased antioxidant enzyme activities, while nanoselenium supplementation resulted in higher selenium deposition in kidney tissue.

Summary: Improving the nutrition of aged laying hens is crucial for enhancing egg production. This study found that selenium yeast (SY) can ameliorate the decline in laying performance and regulate the intestinal microbiota in aged laying hens. Additionally, SY supplementation activates metabolic processes, immune responses, and oxidative stress responses.

Summary: The decline in egg quality during the late stage of the laying cycle is a significant issue in the poultry industry, causing economic losses. Our study showed that supplementing with 0.45 mg/kg selenium yeast can alleviate the decline in egg quality in aged laying hens. Additionally, selenium supplementation increased organ selenium levels and plasma antioxidant capacity. Transcriptomic analysis identified key candidate genes and potential molecular processes involved in the effect of selenium yeast on eggshell formation. Overall, our findings provide valuable insights into improving egg quality and extending the laying cycle in aged laying hens.

Summary: This study aimed to compare the superior antagonistic effects of Nano-Se, SeY, and SSe on Cd-induced inflammation response through the NF-kB/I kappa B pathway in the heart. Results demonstrated that Nano-Se was more effective in reversing Cd-induced histopathological changes and iNOS activities, reducing Cd accumulation, and antagonizing Cd-triggered inflammation response in chicken hearts compared to SeY and SSe. Se applications, especially Nano-Se, can be most efficiently used for relieving cardiotoxicity induced by Cd exposure.

Summary: This study investigated the effects of Cardamine violifolia (SEC) on laying performance and ovarian antioxidant capacity in aging laying hens. The results showed that supplementation with SEC improved laying rate, egg quality, and ovarian antioxidant capacity, exerting an antioxidant function through the modulation of the Nrf2/Keap1 signaling pathway.

Summary: The present study investigated the impact of dietary supplementation with nano-elemental, inorganic, and organic selenium (Se) on the Se content, fatty acid (FA) composition, and oxidative stability of meat. The findings revealed that both dietary supplementation with Se nanoparticles (SeNP) and a combination of sodium selenite and selenium yeast (SS+SY) significantly increased the Se levels in the breast tissue and decreased the concentrations of malondialdehyde (MDA). Furthermore, SeNP supplementation resulted in a more desirable modification of the FA composition, with higher levels of docosahexaenoic acid (22:6n-3) and total n-3 FA compared to the SS+SY group.

Summary: The study aimed to estimate the genetic parameters for traits related to nest preference and laying duration. The results showed that selecting hens that have no preference for particular nests and spend little time in the nests could help reduce the occurrence of floor eggs.

Summary: Poultry production is associated with the use of veterinary medicinal products to manage diseases. Ionophore coccidiostats, although prohibited for use in laying hens, are frequently found in commercial poultry eggs. Various factors influence the presence of residues in eggs, with the carryover of coccidiostats from feed to laying hens being the main reason. This paper reviews the causes of residue occurrence and highlights the potential application of pharmacokinetic modeling for predicting residue transfer in eggs.

Summary: This study investigated the effects of fipronil on laying hens. The results showed that doses at or below 20 mg/kg bw had no significant effects on body weight and egg production. However, hens exposed to 63.3 mg/kg bw showed significant adverse effects, including reduced body weight, lower egg yield, and histopathological changes in the liver and kidney. Furthermore, fipronil-sulfone, a metabolite of fipronil, was found to have higher concentrations and longer withdrawal periods in eggs. This highlights the potential food safety risk of fipronil-sulfone.

Summary: This study investigated the impact of feeding dried stevia leaves on the quality and antioxidant content of eggs. The results showed that feeding stevia-enriched feed can improve the color of egg yolks, and birds fed 2% stevia had the highest carotenoid content in their eggs. Storage also affected the quality of egg albumen.

Summary: This study investigated the effects of methyl sulfonyl methane (MSM) and selenium yeast (Se-Y) on production performance, liver steatosis, and antioxidant index in laying hens, and explored the biological mechanisms of MSM and Se-Y to alleviate fatty liver syndrome (FLS) via RNA-seq technology. The results provide a reference for the prevention and treatment of FLS in laying hens during the late peak laying period.
