Influence of environmental factors and parity on milk yield dynamics in barn-housed dairy cattle

open access: yesJournal 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.

Milk Composition and Production Efficiency within Feed-To-Yield Systems on Commercial Dairy Farms in Northern Ireland

open access: yesAnimals, 2022
This study examined the relationships between milk yield and diet composition, nutrient intakes, milk composition, and feed use efficiency when concentrates were offered using a feed-to-yield (FTY) approach.

Decreased milk yield is associated with delayed milk ejection [PDF]

open access: yesJournal 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 ...

The effect of milking frequency on milk yield and milk composition in ewes [PDF]

open access: yesCzech 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

Evaluation of Milk Yield and Milk Composition of Honamlı Goats

open access: yesJournal of the Hellenic Veterinary Medical Society, 2021
The aim of this study was to determine the milk yield and milk composition (total solids, fat, protein and lactose), freezing point depressionand somatic cell counts of Honamlı goat during second lactationin Turkey. The animal material of the study consisted of a total of 30 goat. Total milk yield was detected by using Fleischmann’s method.
