Enzymy paszowe w żywieniu drobiu, cz. II
Katarzyna Perz, Marcin Hejdysz
Proteazy
Na przestrzeni ostatnich kilkudziesięciu lat obserwuje się stały wzrost produkcji drobiarskiej zarówno w Polsce, jak i na całym świecie. Głównym czynnikiem determinującym utrzymanie tego trendu jest wzrost zapotrzebowania na żywność, przede wszystkim na mięso drobiowe i jego rosnąca popularność. Wysoki stopień intensyfikacji produkcji drobiarskiej wpływa na zwiększające się zanieczyszczenie gleby i powietrza różnorodnymi związkami azotu, które są przez ptaki wydalane (Oxenboll i in., 2011).
