as such there is nio recommendations for any nano minerals in livestock and poultry feeding. we have to see differented works and reports and like wise we have to frame our research and levels of inclusion.
regarding nano Se
here is one article for your reference

Comparative study on the effect of nano selenium (nano-Se) and sodium selenite on the growth, bioavailability, antioxidative activities, hematological and biochemical parameters, cellular and humoral immunity was done in layer chicks upto 8th week post feeding. The results showed significant differences (p
In the following publication "Cai SJ1, Wu CX, Gong LM, Song T, Wu H, Zhang LY. 2012. Effects of nano-selenium on performance, meat quality, immune function, oxidation resistance, and tissue selenium content in broilers. Poult Sci.91(10):2532-9", the authors reported that 0.3 ppm (mg of Se per kg of diet) is the best selenium dose in broiler chickens which can improve zootechnical parameters, meat quality and well-being in chickens . It is important to take into account the native Se which is presented in the basal diet (e.g. corn, soybean, wheat, etc.) as an organic form therefore more bioavailable.
