Daily milk yield correction factors: What are they? [PDF]

open access: yesJDS Communications, 2023
Cows are typically milked 2 or more times on a test-day, but not all these milkings are sampled and weighed. The initial approach estimated a test-day yield with doubled morning (AM) or evening (PM) yield in the AM-PM milking plans, assuming equal AM and

Effects of Once Versus Twice Daily Milking Throughout Lactation on Milk Yield and Milk Composition in Dairy Goats [PDF]

open access: yesJournal of Dairy Science, 2003
The effects of once (1X) vs. twice (2X) daily milking throughout lactation on milk yield, milk composition, somatic cell count (SCC), and udder health were studied in 32 Murciano-Granadina dairy goats. Goats were assigned at wk 2 of lactation to two treatment groups; once daily milking at 0900 (1X, n = 17), or twice daily milking at 0900 and 1700 (2X ...

Variability and correlation of milk urea content with parameters of cow productivity [PDF]

open access: yesE3S Web of Conferences, 2021
During the work, 24774 individual milk samples for Ayrshire cows (Karelia, Russia) with an annual milk yield of over 8.300 kg were tested (1.355 cows) every month for the last three years. The urea content averaged 32.19 mg% with a daily yield of 25.5 kg.

Can meteorological data improve the short-term prediction of individual milk yield in dairy cows?

open access: yesJournal of Dairy Science, 2023
: Many farms document daily milk yields of individual cows because these are a good indicator of cow well-being. It is established that extreme meteorological conditions influence the milk yields by causing heat and cold stress, whereas less is known ...
