“…It also improves the histological structure of the cortex, as shown in this study's findings. Except for the relevance of organic selenium in impacting the gene expression of the cortex gland in hens (26), there has been no past studies into the effect of nanoscale selenium in the shell gland. The positive role of nano selenium can be attributed to the properties of nanoparticles (27).…”

Nanotechnology has proposed many new effective forms of nutritional supplement ingredients due to their low toxicity and high bioavailability, among which are nanoselenium, due to their distinctive properties of small particles and increased surface area of compounds, allowing the opportunity for biological interactions. In this study, 48 laying hens, aged 47 weeks, of a rose type were used, and the experiment lasted for two months. The birds were fed two types of diets, one standard and the other a non-standard diet, represented by the use of crushed yellow corn for molting. The birds were divided into six groups 8 birds/group, with the first group receiving a standard diet, the second group receiving only yellow tops crushed, the third group receiving organic-Se 2 g/L with a standard diet, the fourth group receiving Nano-Se 0.5 ml/L with standard stalk, the fifth group receiving organic-Se with straw 2 g/L, and the sixth group receiving nano-Se with straw 0.5 ml/L. The results showed a significant rise in ovary weight, oviduct weight, number of immature and mature follicles, FSH, LH, as well as an improvement in the histological characteristics of the shell gland in the groups treated with nano and organic-Se, indicating that nano-Se plays a critical role in restoring most reproductive and histological parameters to their normal levels, close to the baseline. This study found that organic and nano-Se are crucial in improving most reproductive and physiological parameters of laying hens exposed to molting.

Background The rising popularity of eggs as an alternative source of protein to meat has led to significant increase in egg consumption over the past decade. To meet the increasing demand for eggs, poultry farmers have used antibiotics to treat infections and, to some extent, promote growth and egg production in raising layer. However, the emergence and global spread of antibiotic resistant bacteria has now necessitated antibiotic-free poultry farming. As alternatives to antibiotics, prebiotics are feed additives that can be used to improve the growth and laying performance of poultry which positively impacts their performance and general health. In this study we evaluated the effect of lactulose, formulated as Vetelact, on body weight, egg production, egg quality, blood biochemical parameters and expression of genes associated with reproductive performance in laying hens. Results Vetelact supplementation improved egg weight, egg production as well as egg quality. Following Vetalact supplementation, the levels of total bilirubin, total protein, globulin and phosphorus were increased, while the activities of alkaline phosphatase and lipase enzymes were increased compared to control. Vetelact at 0.10 ml/kg body weight upregulated OCX-36, OVAL, CALB1, OC-116, OCX-32 and IL8 transcripts while downregulating the transcription of Gal-10, PENK and AvBD9. At this optimal inclusion rate of Vetalect, histomorphologic analyses of intestinal tissue showed increased villi length with more goblet cell distribution and obvious mucus covering a surface, increase in the depth of intestinal crypts produce digestive enzymes, as well as more developed muscle layer that promote improved nutrient absorption. Conclusion Vetelact at a dose of 0.10 ml/ kg body weight was effective in improving productive performance of laying hens. Adding lactulose (0.10 ml/ kg body weight) to layer diet is recommended to promote growth and improve egg laying performance in antibiotics-free poultry production.

Betaine has been found to alleviate oxidative stress, inflammation, and apoptosis. However, whether dietary betaine can protect late-laying hens against these adverse effects is unknown. Here, 270 65-week-old Jinghong-1 laying hens were randomly divided into the Control, 0.1% Betaine, and 0.5% Betaine groups and fed a basal diet, 0.1%, and 0.5% betaine supplemented diet, respectively. The trial lasted for seven weeks. Birds that consumed 0.5% betaine laid more eggs with thicker eggshells. Accordingly, uterine reduced glutathione (GSH), glutathione peroxidase (GSH-PX), and ovarian superoxide dismutase (SOD) contents were increased. The uterine calcium ion content and the mRNA expression of ovalbumin, ovotransferrin, and carbonic anhydrase two were increased. Moreover, ovarian IL-1β, Caspase-1, Caspase-8, and Caspase-9 mRNA expressions were decreased; luteinising hormone receptor (LHR) and follicle-stimulating hormone receptor mRNA expressions were increased. Furthermore, dietary betaine decreased the ovaries’ mRNA expression of DNA methyltransferase 1 (DNMT)1, DNMT3a, and DNMT3b. The methylation level at the promoter region of ovarian LHR decreased. These results indicated that dietary betaine consumption with a concentration of 0.5% could increase the laying rate and the eggshell thickness during the late-laying period. The underlying mechanism may include antioxidative, anti-apoptosis, and hormone-sensitivity-enhancing properties.
