In order to investigate the relative merits of mats and mattresses in terms of cow comfort, production and performance, 29 cows were housed on ethylethene vinyl acetate (EVA) mats and 29 on mattresses of loose rubber crumb with a polypropylene cover, at each of two similar dairy units (SAC Auchincruive and Myerscough). Both mats and mattresses were newly installed at the start of the trial. The...

Interactions between inflammatory cytokines and plasminogen (Pg) activation system on immune cells are yet to be established. In previous studies we reported a somatic cell-associated elevation of proteolytic activity in mammary secretion of drying-off goats and cows. The purposes of the present study were to examine the role of TNF-alpha in polymorphonuclear neutrophil (PMN)-associated Pg acti...

Objective- To compare the time of onset, duration of action and the extent of analgesia produced by a lidocaine/xylazine combination with that produced by lidocaine and xylazine alone after injection into the caudal extradural space of the Iranian river buffalo. Design- Observer-blind prospective descriptive trial, Latin square design.   Animals-  Eleven adult (aged over 2 years) female non-...

In a foster cow system, one or more calves are reared by cow. With regard to the growing rejection towards early separation of and calf after calving, such alternative rearing methods with prolonged cow–calf contact coming into focus. Nevertheless, there is lack recent studies investigating effects suckling multiple on udder health The present study aimed initially describe status development c...

A highly efficient and stereocontrolled synthesis of an aminooxy derivative of the tetrasaccharide repeating unit of a rhamnose-rich polysaccharide isolated from the cell envelop of bovine mastitis Streptococcus dysgalactiae 2023 is reported for the first time. The synthesis was accomplished utilizing a stereoselective and convergent [2 + 2] glycosylation strategy inclusive of a disaccharide Sc...

The aim of this study was to describe and analyze effects of parity, stage of lactation, milkability (3 groups of cows with differing peak flow rates), time of milking, and quarter position on milk production and milk flow measures at udder and quarter levels. Particular emphasis was put on changes to the decline phase and in duration of overmilking. More than 75,800 quarter milk flow curves an...

To obtain best results in treatment, an adequate concentration of the drug must be maintained in the udder for a period of time. Best results are usually obtained when the drugs are administered once or twice daily over a period of 2 to 4 days, depending upon the causative agent and the nature of the case. Most staphylococcal infections must be treated longer than streptococcal infections. Clin...

This study identifies and compares the distribution of mononuclear cells in the mammary gland tissues and milk of healthy and chronically infected with Staphylococcus aureus cows. Somatic cell counts (SCCs) during the 3 months before the study were > 1 x 10(6) cell/ml in the infected quarters and < 1 x 10(5) cell/ml in the infection-free quarters. Immediately after slaughter, samples from the t...

BACKGROUND Mastitis in dairy cattle results from infection of mammary tissue by a range of micro-organisms but principally coliform bacteria and Gram positive bacteria such as Staphylococcus aureus. The former species are often acquired by environmental contamination while S. aureus is particularly problematic due to its resistance to antibiotic treatments and ability to reside within mammary t...
