Incubation Parameters in the Transylvanian Naked Neck Breed Following Supplementation with Vitamin E and Selenium

The importance of the Transylvanian Naked Neck breed is highlighted not only from an economic standpoint but also from a cultural perspective, due to its adaptability to maintenance conditions and its robustness. The two nutrients, vitamin E and selenium, support the biological processes involved in reproduction and organism development, making them essential. Introducing these nutrients in the context of bird egg incubation can positively influence incubation parameters and hatch rates. The biological material consisted of birds from the Transylvanian Naked Neck breed, which were divided into two groups. The experimental group received a supplement of vitamin E and selenium in their drinking water. Supplementation with vitamin E and selenium improved egg weight, hatch percentage, and chick weight at hatching.
