The effect of milking on the length and diameter of the teat canal during teat regeneration immediately after milking was evaluated. The practical measurements of the teat canal were performed on 70 H...
Parturient paresis and subclinical hypocalcemia are frequent metabolic disorders in dairy cows postpartum. The aim of this study was to determine the effect of postpartum partial milking in the first ...
The aim of this paper was to study some of the teat characteristics involved in the milking ability of indigenous Greek goats such as the vacuum level of the milking machine that is required for the o...
Problems with milking and udder health can be attributed to the following causes: (1) sound intensity level (noise) > 65 dB in the milking area, (2) transmission of oscillation (vibration) > 0.3 m/s2 ...
The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties ...
To maintain a predominantly pasture-based system, the large herd milked by automatic milking rotary would be required to walk significant distances. Walking distances of greater than 1-km are associat...
One of the challenges to increase milk production in a large pasture-based herd with an automatic milking system (AMS) is to grow forages within a 1-km radius, as increases in walking distance increas...
Pasture-based automatic milking systems (AMS) require cow traffic to enable cows to be milked. The interval between milkings can be manipulated by strategically allocating pasture. The current experim...
The objective of this study was to examine the effects of concentrates containing different levels of a vitamin-trace elements premix on milk yield and composition of dairy cows. The trial, which last...

The aim of the performed work was to verify the hypothesis that different milking equipments have different influence on the blood circulation in the milk gland during milking. This influence was inve...
When an automatic milking system (AMS) is introduced on a farm the milking of cows and related work is changed in many ways compared to farms with traditional milking systems. The objective of this pa...
The paper deals with the detection of “idle milking” times for individual quarters of the udder in a group of dairy cows (randomly selected) in a parallel 2 × 12 milking parlour. A non-contact laser t...
A random sample of 40 goats was used to study the partitioning, yield and composition of milk: 8 of Saanen breed (S), 8 of Damascus breed (D), 8 crossbreds Saanen × Local Greek goat (S × L), 8 backcro...
