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

Four experiments were performed to determine whether cooling cows during final maturation of oocytes and early embryonic development or injection of vitamin E at AI prevented adverse effects of heat stress on pregnancy rates in lactating Holstein dai

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
