“…Nano-selenium at 0.3 mg/kg of feed increased estrogen (36). When given at a concentration of 4 ml/kg of body weight, selenium improves the effectiveness of the ovaries, estrogen, and progesterone (37). The number of tubular glands and goblet cells increased, which increased the thickness of the epithelium of the mucous layer of the cortical gland and an increase in the lumen between the microvilli, the antioxidant role of selenium in improving the internal environment of the bird through its antioxidant role and protection from the harmful effects of free radicals resulting from metabolism, increasing glutathione activity, and lowering the level of malondialdehyde can be attributed to the important role of selenium in improving the internal environment of the bird through its antioxidant role and protection from the harmful effects of radicals resulting from metabolism (38,39).…”

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.
