Introduction • CBPP is an infectious disease of cattle which has a huge impact on the society. • CBPP is caused by Mycoplasma mycoides subspecies mycoides Small Colony variant (Mmm. SC). • The organism produces natural infection in cattle and water buffaloes (Bubalu babulus), but not in wild buffaloes (Syncerus caffer). • CBPP is widespread in Africa and it is recognized to be present in some countries of Asia and Europe. 23/01/2022 3

Introduction • In Africa, it is found in an area south of the Sahara, from the Tropic of Cancer to Tropic of Capricorn and from Atlantic to the Indian Ocean. • Endemic infection extends throughout the pastoral herds of much of western, central and eastern Africa, with Angola and northern Namibia in southern Africa. 23/01/2022 4

Economic analysis framework Fig. 2: Partial budgeting framework Costs Benefits New Costs Treatment of clinical cases Preventive annual vaccinations Cost of feed and management Costs Saved Slaughter fee per head Market prices for cattle Forgone Revenue Salvage value for meat, hides and skins from culled cows Reduced alternative income and social activities New Revenue Extra cows Extra milk production Extra calves born Extra meat (weight gain) 23/01/2022 6

Conclusions • Slaughter of clinical cases of CBPP is not beneficial to pastoralists • Treatment of clinical cases, annual vaccination and a combination of these two strategies have benefits to pastoralists • Vaccination services against CBPP can be delivered through signed contractual agreements between private and public veterinary departments 23/01/2022 18
