Subject and purpose of work: The aim of this research was to determine changes in the population of native animal breeds and to indicate the importance of subsidies under agri-environmental programs. The study concerned the years 1999-2017. Materials and methods: The research was based on the documentation of the National Research Institute of Animal Production (PIB). An assessment of the population size of native animal breeds was carried out depending on the amount of subsidies from the national subsidy up to 2004 and from agri-environmental programs since 2005. Results: Since the integration of Poland with the European Union and the mobilization of funds from agri-environmental programs, a successive increase in the number of farm animals covered by the protection program has been noted. Conclusions: This investigation demonstrated a considerable, but not exclusive dependence of the dynamics of the growth of the livestock population covered by the protection program on the amount of subsidies for breeders. The preservation of EU subsidies through agri-environmental programs in the years to come is the basis for maintaining the upward trend in the abundance of native livestock populations. Also, a greater increase in the number of animals than in the number of new beneficiaries using agri-environmental programs was observed, and this is a situation conducive to breeding work. National surveys show that native breeds are a source of obtaining products with pro-health, regional and traditional properties, for which the demand is growing, and which can also help to protect the biodiversity of farm animals.

The aim of the study was to evaluate the quality of eggs from 56-week-old hens of the native Greenleg Partridge chicken breed, maintained in three production systems and differentiated by feeding – organic (group 1), backyard (group 2) and intensive, kept indoors in a poultry Mouse (group 3 – control). Egg quality and eggshell traits were found to be related to the production groups. The eggs laid by hens from group 1 were characterized by the highest total weight and highest weight of yolk which had the most desirable colour. The yolks of these eggs were characterized by the lowest level of cholesterol and the lowest shell strength. with the highest level of vitamin E. In the backyard production system (group 2) eggs were characterized by the lowest total weight and yolk weight, the highest protein content of albumen, the highest vitamin A and the lowest vitamin E content of yolk as well as lower shell crushing strength compared to the control group.
