Decreased milk yield is associated with delayed milk ejection [PDF]
Journal of Dairy Science, 2019 To determine whether individual cow milking vacuum (within the short milk tube and the liner mouthpiece) could be substituted for milk flow technology to identify delayed (bimodal) milk ejection, and the possible relationship between bimodal milk flow and milk yield, we recorded milking data from 663 Holstein cows on a 3,600-cow Michigan dairy that ...

Influence of environmental factors and parity on milk yield dynamics in barn-housed dairy cattle
Journal of Dairy Science, 2022 : We investigated the effects of environmental factors on average daily milk yield and day-to-day variation in milk yield of barn-housed Scottish dairy cows milked with an automated milking system.

The effect of milking frequency on milk yield and milk composition in ewes [PDF]
Czech Journal of Animal Science, 2020 Milking frequency is the main factor regulating milk yield and milk quality if feeding, welfare, health, and environmental conditions are adequate. Milk yield and composition are substantially influenced by breed, and consequently the breed has an impact
