Heat stress in hot and humid environments reduces milk production, decreases reproduction, and increases health-related problems. The summertime environment in north-central Florida is especially difficult because the combination of high relative hum

A milking parlor simulation and a stochastic model for a capital budget for the parlor were used to determine economically preferred parlors within three milking facility sizes [40 stalls (double-20 herringbone or double-20 parallel), 64 stalls (two

A network simulation model of herringbone and parallel milking parlors was built. Parlor performance was predicted based on the number of cows milked per hour and the amount of milk harvested per shift. Modeled parlors operated using a task-oriented

A prediction method for individual cow milking time for use in milking parlor simulation models was formulated as a function of pulsation ratio, vacuum, and milk yield per cow per milking. Milking time was divided into two components: lag time, consi

An experiment was conducted in a large commercial dairy milking 1350 Holstein cows in Florida to investigate the effects of 50:50 or 70:30 pulsation ratios on milking parlor performance, milk production, and udder health. The experiment used a revers

A simulation model of double-16 and double-20 herringbone and parallel milking parlors and double-32 and double-40 parallel milking parlors was used to examine the effects of size, design, operating characteristics of the milking system, management s

Clinical mastitis records for 6.5 yr from a large north Florida dairy and corresponding daily weather data were analyzed. Monthly incidence of clinical mastitis was expressed as percent of cow-days in milk and graphed against monthly average daily ma
