Perceptions of Factors Affecting Milk Quality and Safety among Large- and Small-Scale Dairy Farmers in Zimbabwe

Table 2

Odds ratio estimate and lower (LCI) and upper confidence interval (UCI) of farmers indicating that different factors affect milk quality.

LCI: lowest confidence interval, UCI: upper confidence interval, Sig.: significance, NS: not significant (), ; higher odds ratio estimates indicate greater difference in preference levels of predictors.
