How can we compare multispecies livestock rearing households? – an analysis of the impact of health and production parameters on multispecies livestock rearing outcomes

Table 4 Factors associated with the reported occurrence of different livestock health problems on cattle, small ruminant and village chicken farms in the CDZ of Myanmar (each health problem-species combination represents a separate analysis)
