2023 has been declared the Year of the Teacher and Mentor by the President of Russia. Stavropol State Agrarian University is famous for its outstanding teachers, who are widely known in the region, in the country and abroad. We are starting a series of interviews with educators in which they will present their views on teaching, education and students. We open the column with an interview with one of the elders of the university - Professor of the Department of Animal Feeding and General Biology, Doctor of Agricultural Sciences, Professor Nikolai Zakharovich Zlydnev. How have students changed in 50 years? What should new teachers do? Where did the love for studying cows come from?
