Milking-time Test – Methodology and Assessment of Vacuum Recordings during Machine Milking of Dairy Cows
The aim of the study was to improve the basic understanding and the methodology of routine milking-time testing by determining the required sampling frequency and number of cows and milkings needed to be measured in order to yield representative results. Milking-time tests represent the most direct method to validate the system vacuum of a milking machine, both the aptitude of vacuum production...
متن کاملQuarter Individual Milking in Conventional Milking Parlours
In this study, a new quarter individual milking system called Multilactor® (MULTI) was compared with a conventional milking system (CON). The target of the developments in the field of milking technique is to obtain the whole milk from the teat of the animal in the shortest possible time without causing any detrimental effect on udder health. The most direct measure of the milking system effect...
متن کاملChanges in milking parameters with robotic milking
The aim of this present study is to describe changes occurring during the milking of cows in various periods following the introduction of an AMS (automatic milking system). The following cow milking parameters were analysed: milkings per cow per day, milking yield, milking speed and milking duration. An increase in milk yield in AMS barns has been found to be possible, but it is affected by a ...
متن کاملMilking it
Evolutionary biologists have long pondered the origin of lactation in mammals: converting food into milk is energetically expensive and can consume up to 25 per cent of the food's original value. But it is ubiquitous amongst mammals although absent in birds. A new study Proceedings of the Royal Society series B (published online), has modelled the potential benefits of lactation. They have cont...
متن کاملThe effects of different milking intervals and milking times per day in jennet milk production.
In their first 150 days of lactation, nine Ragusana jennets were investigated at the 'Istituto Sperimentale Zootecnico per la Sicilia' (ISZS) in Palermo, to study the effects of different milking typologies on milk production. The jennets were kept in a paddock and were fed hay ad libitum and concentrate (3.5 kg jennet/day). From post-foaling day 21, every 3 weeks individual milk amounts were r...
