Over the past decade (2013-2023), the ruminant population in Bangladesh has increased substantially (between 1.46 and 26.95 million individuals), with goats showing the most significant growth, while financial losses due to bovine brucellosis have risen steadily, emphasizing its economic impact (basis on species between Euro currency 12.824 and 298.272).
