TL;DR: Correlations between milk production on test day, and the sum of milk produced on ten test days, were higher for the young cows, were similar for different milking frequencies in the same age group, and were highest during the 4th to 7th mo.

TL;DR: Findings support data in the literature which suggest that production records of only 1 or 2 mo. are valuable guides to what a cow will produce in that lactation, and suggest that herd had little or no influence on the part-to-whole relationship.

TL;DR: Analysis of Michigan DHIA Holstein records from 1944 to 1956 supports the conclusion that significant differences in transmitting ability have not been present between groups of AB and non-AB sires studied.

TL;DR: In this paper, the average total solids measured by the small Quevenne lactometer differed significantly from the gravimetric measurements in milk from several breed and fat level groups.
