The fully automated milking system VMS has different functions which complements the actual milking of cows. This master thesis presents a method to improve the calculation of milk yield in dairy cows for the VMS. This report also investigates if it is possible to improve the algorithm for finding cows with mastitis (udder inflammation). The correctness of the prediction of milk yield is import...

milk and fat yields in 3x and 4x milking schedule in holstein cows of iran were investigatedusing 374170 milk and fat yield test day records measured on the 1st and 2nd lactions of 54580 dairycattle coming from 205 herds. the records had been collected from 2007 to 2009 by the iraniananimal breeding center (iabc). the results indicated that an increases in the milking frequency from3x to 4x inc...

Overmilking is a matter of concern because it may affect teat condition and udder health. The historic background for overmilking is mainly based on the assumption that all milk should be removed from the udder in order to maximise the milk yield. However, breeding for high milk yields has provided cows with a high alveolar capacity, large cistern capacity, and a higher proportion of cisternal ...

This paper reports a use of flexible bodies in Multi Body System (MBS) modeling. A combination of discrete and modal flexibility enables structural eigenfrequency investigation. The Voluntary Milking System (VMS) is a product from Swedish agricultural company DeLaval AB [1]. The VMS introduces an entirely different way of milking cows. The cows themselves decide when its time to be milked and ...

background: 99mtc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from mo-99/tc-99m generators. usually the generators are either supplied by the iran atomic energy agency or by private companies from foreign countries. in this study we have measured 99mo contamination in 99mtc elute from different generators in a period of one year. materials and methods:...

This manuscript presents the idea of providing dairy farmers with probability distributions to support decisions on mastitis management and illustrates its feasibility by two applications. Naive Bayesian networks were developed for both applications. The networks in the first application were used to compute probability distributions to support decisions on which cows from a mastitis alert list...

This paper reports an experiment conducted to assess the contribution of a computer system in the milking parlor to the detection of mastitis and estrous (udder infection and the time to inseminate the cow). The experiment was carried out in a herd of 700 cows in Israel. It was found that the computer system contributed markedly to the cows' productivity and profitability. (

In order to determine the possible effects of udder traits on milk yield and milk composition a serial of experiments were carried out on five different sheep farms, between 1998-2000. Ten breeds and genotypes were included in these experiments: Merino, (Merino x Pleven Blackhead) F1, Pleven F1 x Black East Friesian, Lacaune, (Merino x Lacaune) F1, British Milksheep, (Merino x British Milksheep...
