Abstract
Daily composite samples of whole milk received at the plant from about 6000 herds were tested for fat by the Babcock test. Daily composite samples of this same milk after separation of cream were tested for total solids. Mean daily temps. covering the period during which this milk was being secreted were secured from the local weather bureau. Correlation coeffs. between mean daily fat test of the whole milk and the mean daily temp, ranged from -0.258 to -0.838 averaged -0.657 for 1946, using monthly intervals. Correlation coeffs. between mean daily total solids of separated milk and mean daily temps, ranged from[long dash]0.062 to[long dash]0.758 and averaged[long dash]0.443 for 1946, using monthly intervals. There was an av. increase of 0.067% total solids of the separated milk and an av. increase of 0.093% fat of the whole milk for each 10[degree]F decrease in atmospheric temp.
