This article discusses practical aspects of a non-invasive method to administer biostimulants inside the egg versus an injection method. Considering literature data and our own long-term studies, benefits and disadvantages were identified for each method of biostimulant administration. Given a large number of small poultry farms, the non-invasive method is technologically simple and cost-effective for the poultry industry. The purpose of this research was to determine the effectiveness of certain biostimulants composition for different types of poultry in a non-invasive way of its administration. The studies were conducted on different poultry farms in the Russian Federation. The experiments used eggs of Hybrid Converter turkeys, Japanese quails, grey-speckled guineafowls, and Ross 308 broilers. Biological control indicators of incubation were recorded against hatched eggs by a method generally accepted on the poultry farms. We received positive results that proved the high efficiency of the non-invasive method of delivering biostimulants into eggs, which contributed to the increased hatchability of young birds. Thus, considering all advantages of the presented method, it can be recommended for use on poultry farms.
