In normal use, milking parlor can cause the release of oxytocin through neuroendocrine reflex, but the use of milking parlor sometimes cause stress and lead to a decrease in milk production. In Indonesia at this time, traditional milking by hand is still widely used by dairy farmers. The purpose of this study is to investigate the use of milking parlor to the physiological and behavioral respon...
Effect of milking behavior on circulatory hormones and milk production in lactating Murrah buffaloes
The effect of milking temperament on plasma hormones, metabolites, milk yield and composition in lactating Murrah buffaloes was studied. Animals were selected from the institute herd and grouped as docile and nervous buffaloes, based on temperament score before and during milking. Blood sampling times were; before milking (-20 min.), after concentrate intake, after teat massage, during milking ...
OBJECTIVES The primary aim of this cross-sectional research study was to quantify upper limb muscle activity among workers performing milking tasks in large-herd dairy parlors. METHODS Surface electromyography (sEMG) from the trapezius, anterior deltoid, biceps brachii, wrist flexors, and wrist extensors muscles of 26 dairy workers were used to create muscle activity profiles for the milking ...
The main purpose of this article is to describe interaction between physiology of lactation and milking machine. This is important in order to avoid bad influ ences (such as: high somatic cell count (SCC), mastitis, etc.). The paper is divided into two parts: The anatomy part describes udder characteristics needed for healthy udder and high milk yield. The milking machine part describes milkin...
Milk yield, milk flow, and udder morphology traits were measured in 72 East Friesian crossbred multiparous ewes to estimate the variation in milk flow patterns present in this research flock, and to asses the repeatability of these measurements and their relationships with other lactation traits. A special milk flow apparatus designed for dairy ewes was used on two consecutive morning milkings ...
The introduction of automatic milking technology, including on-line individual data acquisition and processing, requires adaptation of dairy management methods. Automatic milking systems allow the individual cow to be milked and fed according to her production performance and potential to achieve maximal profits with minimal resources. Because the farmer is not actually present each time a milk...
Both the new ASAE S518 standard (2) and the revised draft international standard DIS/ISO 5707 (3) incorporate performance standards for vacuum stability in milking systems. New NMC procedures for system evaluation include dynamic tests for vacuum stability to demonstrate the adequacy of new or existing milking systems (7) . Such dynamic (i.e. "milking-time") tests require the use of test instru...
milk samples from high and low milk producer holstein cows, were obtained during the morning and afternoon milking over a one week period. overall, 1064 samples were tested within 14 times sampling in urmia, iran. milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. the highest and lowest concentrations were obse...
Milk yield and plasma oxytocin (OT), prolactin (PRL), and cortisol (CORT) during suckling and machine milking were measured in multiparous ewes subjected to a mixed management system of 3 sucklings and two daily milkings. Peak hormones were significantly increased and were similar during suckling and milking for PRL (181 vs. 163.3 ng x mL(-1)) and CORT (12.5 vs. 11.5 ng x mL(-1)). During the pe...
Prolactin release in response to milking stimulus in the cow and goat estimated by radioimmunoassay.
The effect of milking stimulus on the plasma prolactin concentration of lactating cows and goats was investigated by a radioimmunologic procedure. Plasma prolactin level in seven cows was increased abruptly 1 to 2mins. after the start of milking. On the other hand, the level of the hormone was increased shortly before the onset of milking in two cows at early lactation stage. In the goats at mi...
