Prince Sergei Petrovich Urusov is known for his work in the field of agricultural animal husbandry. Being a contemporary and associate of the fundamental figures of Russian animal husbandry, such as N. P. Chirvinsky, P. N. Kuleshov. E. F. Liskun, A. I. Pridorogin, E. A. Bogdanov and others, he left a fairly large book heritage, which is still of great importance in agriculture. The main attention in his activity is paid to horse breeding and equestrian sports, goat breeding and poultry breeding, although he has some printed works on general animal husbandry, hunting, cattle, pig breeding. For a long time, nothing was said about his merits due to his belonging to the upper class of the Russian Empire.
