Supplementary feeding at milking and minimum milking interval effects on cow traffic and milking performance in a pasture-based automatic milking system

Autor: Peter J. A. Copeman, Murray M Woolford, J. G. Jago, Ian Ohnstad, Kendra L Davis

Publikováno v: Journal of Dairy Research. 74:492-499

In extensive pastoral dairy farming systems herds graze 12 months of the year with the majority fed a near-100% pasture or conserved pasture diet. The viability of automatic milking in these systems will depend partly upon the amount of supplementary

Partitioning of milk accumulation between cisternal and alveolar compartments of the bovine udder: relationship to production loss during once daily milking

Autor: Peter J. A. Copeman, Stephen R. Davis, Kerst Stelwagen, V.C. Farr, Vicki R. Carruthers, Christopher H. Knight

Publikováno v: Europe PubMed Central

Experiments were undertaken to validate a method (using adrenaline injection) for determination of the size of cisternal and alveolar compartments in the udder, to use this method to determine the pattern of milk accumulation in the udder over time a

Effects of oxytocin, machine stripping and milking rate on production loss of cows milked once a day

Autor: Vicki R. Carruthers, Peter J. A. Copeman, Stephen R. Davis

Publikováno v: Journal of Dairy Research. 60:13-18

SummaryThe effect of treatments designed to improve the efficiency of milk removal and minimize loss of production in cows milked once a day (OAD) was assessed in short-term trials involving Friesian and Jersey cows. Trial 1 involved 80 cows and comp

The effect of pre-milking teat-brushing on milk processing time in an automated milking system

Autor: Kendra L Davis, Peter J. A. Copeman, J. G. Jago, Murray M Woolford

Publikováno v: The Journal of dairy research. 73(2)

Cow throughput in an automatic milking system (AMS) is limited by system parameters such as the time required for pre-milking udder preparation and cup attachment, physiological responses of the cow (such as milk let-down and milking-out rate), milki
