The objective of this study was to assess the presence of a Listeria monocytogenes-containing biofilm in milking equipment as a potential source of bulk tank milk contamination on a dairy farm where milk contamination had been previously documented. Samples were collected from milking equipment and milking parlor premises on 4 occasions and analyzed for the presence of L. monocytogenes. Pulsed-...

Milking frequency is known to affect milk production and lactation persistence in dairy cows. Despite this, the mechanisms underlying this effect are only partially understood. Previous work in dairy cows examining increases in milk yield due to increased milking frequency have identified changes in apoptosis and expression of genes regulating cytokine signaling. In addition, changes in mitocho...

The use of PCR tests as diagnostics for intramammary infections (IMI) based on composite milk samples collected in a non-sterile manner at milk recordings is increasing. Carryover of sample material between cows and non-aseptic PCR sampling may be incriminated for misclassification of IMI with Streptococcus agalactiae (S. agalactiae) in dairy herds with conventional milking parlours. Misclassif...

The study aimed to analyze the financial feasibility of implementing robotic milking on a dairy farm in western Santa Catarina/Brazil. This is descriptive case with qualitative basis using semi-structured interviews. Based cost measurement for implementation period activity 2022, comparative analysis was made incremental cash flow relative transition from conventional milking. One major finding...

in this research in order to estimate genetic parameters for milk yield at different milking times for holstein cows of razavi khorasan, a total of 180,462 monthly test day records belonging to first lactation cows calved from 2000 to 2009 were utilized. the records were analysed by a random regression test day model. in the model, the fixed effects of contemporary group of geographical locatio...

Dairy goat farms are growing in the world, but their technological level and, particularly, milking equipment less developed than those of dairy cow farms. This study aims to evaluate parlors current situation modern and suggest possible solutions or improvements. Ten located various municipalities Friuli-Venezia Giulia region (Northeast Italy) adopting different systems (parallel parlors, cart...

Transfer of sufficient immunoglobulin G (IgG) to the neonatal calf via colostrum is vital to provide the calf with immunological protection and resistance against disease. The objective of the present study was to determine the factors associated with both colostral IgG concentration and colostral weight in Irish dairy cows. Fresh colostrum samples were collected from 704 dairy cows of varying ...

Feed, is the primary motivation for the cow to visit the robotic milking stall. Highly motivated cows will visit voluntarily, thereby decreasing the need to expend labor fetching cows, and they will visit more frequently and regularly, leading to higher milk production. Forced cow traffic makes it possible to use forage at the bunk to provide motivation, and while it reduces the number of fetch...
