AbstractFull Text

There is evidence globally that genetic gains in cattle production efficiency traits can also drive improvements in greenhouse gas (GHG) emissions intensity (i.e. methane or CO2 equivalent emissions per unit of product). In this study, we predicted improvements in GHG emissions intensity expected...

6×4 silicone liners covered buckling pressures from 6.5 to 17.9 kPa. Hard PVC teats provided penetration depths from 50-110 mm. Teat length increased liner stiffness by 39-55% which decreased a- and c-phases by 34, 83, 58 ms and 45, 48, 60 ms at 40 kPa alternate pulsation, 40/32 kPa alternate (8...

AbstractFull Text

Sophisticated statistical methods are used to predict the genetic merit of individuals. By utilizing millions of performance records from daughters, parents and other relatives, genetic and environmental effects are well separated to predict the genetic worth of each animal. Their application has...

Abstract

Over the last six years a shared cattle breeding database has been established in Ireland. This database is now being used to meet the information needs of herd books, milk recording, artificial insemination and genetic evaluation for beef and dairy cattle. Development of this database required the ...

AbstractFull Text

Milk Recording Organization from European Countries (Belgium, Germany, UK, Ireland, Luxembourg, France and Austria) worked together with research teams through an European project called OptiMIR. The goal of OptiMIR was to use the MIR spectral data from the milk recording in mathematical models to...

AbstractFull Text

In modern dairy farms, cows are milked at different stages of lactation, while a relatively large number of their glands is infected with a variety of bacteria. Thus, bulk milk quality depends on the mixture of the milked quarters. Even though many dairy animals with subclinical chronic infections...

AbstractFull Text

The cattle ticks represent a particularly important danger for ruminant production, because of the losses they directly cause, or because of the infectious diseases they are associated with. In New Caledonia, as in other tropical regions, the tick Rhipicephalus microplus represents a real plague,...

AbstractFull Text

Four milkmeters, designed for milk yield recording with sheep or goats, have been used for monitoring the settings of flow sensing devices in an automatic milking system. In two sessions data were recorded including the milking of 25 cows and of 28 cows. Parameters evaluated were total milk yield,...

AbstractFull Text

Due to the economic conditions and an efficient and fast milking process many farmers use automatic stimulations and take-offs. In addition to these facilitations there may be a positive effect on udder health. This is caused by the fact that automatic support leads to a constant work flow in...

AbstractFull Text

Investigations under standardised conditions (6 cows, milked and sampled for 16 days with varied milking interval, MI) showed, that increasing MI of 4, 8 and 12 hours lead to decreasing somatic cell count (SCC) of 499, 360 and 297 cells per ml (P≤0,016), respectively. In contrast to our study, some ...
