Clark, C.H. (1966) A survey of the accuracy and use of three milk meters. Queensland Journal of Agricultural and Animal Sciences, 23 (2). pp. 305-308.



Milk yields of 59, 15 and 31 cows were measured with the Milky Weigh, Bodmin and Johnson milk meters respectively, and comparisons were made with scale weights. Meters were accurate in one-third of readings. Most readings with the Milk Weigh meter were higher than weights (positive). Both high and low readings were noted on the Bodmin While most readings were lower than weights (negative) in the case of the Johnson. Of all readings, 83% (Milky Weigh), 74% (Bodmin) and 75% (Johnson) did not deviate more than +- 5 % from weights. Correlation coefficients of 0·9 were derived in the case of each meter. Regression coefficients were calculated and equations for regression lines prepared.
