Regulation of yield loss and milk composition during once-daily milking: a review
Livestock Production Science, 1999Abstract Once-daily milking (ODM) of ruminants results in loss of milk production. In cows this loss is very variable between individuals but in recent short-term trials, on average, the loss was 13%. Full lactation studies indicate losses of 35–50% but documentation from some commercial farms using ODM suggests that losses are lower.

Milk yield and mammary function in dairy cows milked four times daily
Journal of Dairy Research, 1990SummaryGroups of lactating cows and heifers were milked four times daily in two diagonally opposed glands for 4 weeks, and the effects on milk yield studied relative to twice-daily milked glands as controls. Mammary enzyme activities, in vitro synthesis rates of milk constituents and histological scoring were determined in mammary biopsy samples ...

Milk yield and mammary function in goats during and after once-daily milking
Journal of Dairy Research, 1990SummaryStarting in week 5 of lactation, goats were milked unilaterally once daily for 4 ½ weeks, then twice daily for 12 weeks and finally thrice daily for 2 weeks. The control gland was milked twice daily throughout. During less frequent milking, yield fell by 26%.

Estimating daily yields of cows from different milking schemes
Livestock Production Science, 2000Abstract A multiple regression model was used to derive equations for predicting 24 h milk, fat, and protein yields of dairy cows on either two-times or three-times-a-day milking under different testing schemes. New prediction equations were developed for 72 subclasses of days in milk, parity, and season of calving for each of 18 possible three-times-

Once daliy milking of dairy cows: relationship between yield loss and cisternal milk storage
Journal of Dairy Research, 1994SummaryThe proportions of milk stored in the gland cistern (cisternal) and within secretory alveolar tissue (alveolar) were determined for a group of ten cows in mid lactation, yielding ∼ 20 kg milk/d. As a proportion of total milk, cisternal milk, measured at 8 h after milking, ranged from 0·09 to 0·53.

Various approaches to daily milk yield prediction from alternative milk recording scheme
2006The objective of this research was to compare different approaches to daily milk yield prediction from alternative milk recording scheme (single morning and evening milking records). The data used in this study were 3, 730 individual test-day milk yield records collected from November 2004 to November 2005 on 560 cows reared on 15 family farms in ...
